浏览器交互

获取浏览器信息

获取标题

从浏览器中读取当前页面的标题:

      String title = driver.getTitle();
title = driver.title
            String title = driver.Title;
    current_title = driver.title
    let title = await driver.getTitle();
driver.title

获取当前 URL

您可以从浏览器的地址栏读取当前的 URL,使用:

      String url = driver.getCurrentUrl();
title = driver.current_url
            String url = driver.Url;
    current_url = driver.current_url
    let currentUrl = await driver.getCurrentUrl();
driver.currentUrl

1 - 浏览器导航

打开网站

启动浏览器后你要做的第一件事就是打开你的网站。这可以通过一行代码实现:

        //Convenient
        driver.get("https://selenium.dev");
            
        //Longer way
        driver.navigate().to("https://selenium.dev");
driver.get("https://www.selenium.dev/selenium/web/index.html")
            //Convenient
            driver.Url = "https://selenium.dev";
            //Longer
            driver.Navigate().GoToUrl("https://selenium.dev");
    driver.navigate.to 'https://www.selenium.dev/'
    driver.get 'https://www.selenium.dev/'
    expect(driver.current_url).to eq 'https://www.selenium.dev/'
        //Convenient
        await driver.get('https://www.selenium.dev');

        //Longer way
        await driver.navigate().to("https://www.selenium.dev/selenium/web/index.html");
// 简便的方法
driver.get("https://selenium.dev")

// 更长的方法
driver.navigate().to("https://selenium.dev")

后退

按下浏览器的后退按钮:

        //Back
        driver.navigate().back();
            //Back
             driver.Navigate().Back();
    driver.navigate.back
        //Back
        await driver.navigate().back();
driver.navigate().back() 

前进

按下浏览器的前进键:

        //Forward
        driver.navigate().forward();
            //Forward
             driver.Navigate().Forward();
    driver.navigate.forward
        //Forward
        await driver.navigate().forward();
driver.navigate().forward()

刷新

刷新当前页面:

        //Refresh
        driver.navigate().refresh();
            //Refresh
             driver.Navigate().Refresh();
    driver.navigate.refresh
        //Refresh
        await driver.navigate().refresh();
driver.navigate().refresh()

2 - JavaScript 警告框,提示框和确认框

WebDriver提供了一个API, 用于处理JavaScript提供的三种类型的原生弹窗消息. 这些弹窗由浏览器提供限定的样式.

Alerts 警告框

其中最基本的称为警告框, 它显示一条自定义消息, 以及一个用于关闭该警告的按钮, 在大多数浏览器中标记为"确定"(OK). 在大多数浏览器中, 也可以通过按"关闭"(close)按钮将其关闭, 但这始终与“确定”按钮具有相同的作用. 查看样例警告框.

WebDriver可以从弹窗获取文本并接受或关闭这些警告.

	         Alert alert=driver.switchTo().alert();
	         //Store the alert text in a variable and verify it
	         String text = alert.getText();
	         assertEquals(text,"Sample Alert"); 
	         //Press the OK button
	         alert.accept();
	                
    element = driver.find_element(By.LINK_TEXT, "See an example alert")
    element.click()

    wait = WebDriverWait(driver, timeout=2)
    alert = wait.until(lambda d : d.switch_to.alert)
    text = alert.text
    alert.accept()
//Click the link to activate the alert
driver.FindElement(By.LinkText("See an example alert")).Click();

//Wait for the alert to be displayed and store it in a variable
IAlert alert = wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert text in a variable
string text = alert.Text;

//Press the OK button
alert.Accept();
  
    # Store the alert reference in a variable
    alert = driver.switch_to.alert

    # Get the text of the alert
    alert.text

    # Press on Cancel button
    alert.dismiss
            let alert = await driver.switchTo().alert();
            let alertText = await alert.getText();
            await alert.accept();
//Click the link to activate the alert
driver.findElement(By.linkText("See an example alert")).click()

//Wait for the alert to be displayed and store it in a variable
val alert = wait.until(ExpectedConditions.alertIsPresent())

//Store the alert text in a variable
val text = alert.getText()

//Press the OK button
alert.accept()
  

Confirm 确认框

确认框类似于警告框, 不同之处在于用户还可以选择取消消息. 查看样例确认框.

此示例还呈现了警告的另一种实现:

	         alert = driver.switchTo().alert();
	         //Store the alert text in a variable and verify it
	         text = alert.getText();
	         assertEquals(text,"Are you sure?"); 
	         //Press the Cancel button
	         alert.dismiss();
	         
    element = driver.find_element(By.LINK_TEXT, "See a sample confirm")
    driver.execute_script("arguments[0].click();", element)

    wait = WebDriverWait(driver, timeout=2)
    alert = wait.until(lambda d : d.switch_to.alert)
    text = alert.text
    alert.dismiss()
//Click the link to activate the alert
driver.FindElement(By.LinkText("See a sample confirm")).Click();

//Wait for the alert to be displayed
wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert in a variable
IAlert alert = driver.SwitchTo().Alert();

//Store the alert in a variable for reuse
string text = alert.Text;

//Press the Cancel button
alert.Dismiss();
  
    # Store the alert reference in a variable
    alert = driver.switch_to.alert

    # Get the text of the alert
    alert.text

    # Press on Cancel button
    alert.dismiss
            let alert = await driver.switchTo().alert();
            let alertText = await alert.getText();
            // Verify
//Click the link to activate the alert
driver.findElement(By.linkText("See a sample confirm")).click()

//Wait for the alert to be displayed
wait.until(ExpectedConditions.alertIsPresent())

//Store the alert in a variable
val alert = driver.switchTo().alert()

//Store the alert in a variable for reuse
val text = alert.text

//Press the Cancel button
alert.dismiss()
  

Prompt 提示框

提示框与确认框相似, 不同之处在于它们还包括文本输入. 与处理表单元素类似, 您可以使用WebDriver的sendKeys来填写响应. 这将完全替换占位符文本. 按下取消按钮将不会提交任何文本. 查看样例提示框.

             alert = driver.switchTo().alert();
	         //Store the alert text in a variable and verify it
	         text = alert.getText();
	         assertEquals(text,"What is your name?"); 
	         //Type your message
	         alert.sendKeys("Selenium");
	         //Press the OK button
	         alert.accept();
	         //quit the browser
    element = driver.find_element(By.LINK_TEXT, "See a sample prompt")
    driver.execute_script("arguments[0].click();", element)

    wait = WebDriverWait(driver, timeout=2)
    alert = wait.until(lambda d : d.switch_to.alert)
    alert.send_keys("Selenium")
    text = alert.text
    alert.accept()
//Click the link to activate the alert
driver.FindElement(By.LinkText("See a sample prompt")).Click();

//Wait for the alert to be displayed and store it in a variable
IAlert alert = wait.Until(ExpectedConditions.AlertIsPresent());

//Type your message
alert.SendKeys("Selenium");

//Press the OK button
alert.Accept();
  
    # Store the alert reference in a variable
    alert = driver.switch_to.alert

    # Type a message
    alert.send_keys('selenium')

    # Press on Ok button
    alert.accept
            await driver.wait(until.alertIsPresent());
            let alert = await driver.switchTo().alert();
            //Type your message
            await alert.sendKeys(text);
//Click the link to activate the alert
driver.findElement(By.linkText("See a sample prompt")).click()

//Wait for the alert to be displayed and store it in a variable
val alert = wait.until(ExpectedConditions.alertIsPresent())

//Type your message
alert.sendKeys("Selenium")

//Press the OK button
alert.accept()
  

3 - 同cookies一起工作

Cookie是从网站发送并存储在您的计算机中的一小段数据. Cookies主要用于识别用户并加载存储的信息.

WebDriver API提供了一种使用内置的方法与Cookie进行交互:

这个方法常常用于将cookie添加到当前访问的上下文中. 添加Cookie仅接受一组已定义的可序列化JSON对象. 这里 是一个链接, 用于描述可接受的JSON键值的列表

首先, 您需要位于有效Cookie的域上. 如果您在开始与网站进行交互之前尝试预设cookie, 并且您的首页很大或需要一段时间才能加载完毕, 则可以选择在网站上找到一个较小的页面 (通常404页很小, 例如 http://example.com/some404page)

	      driver.get("https://www.selenium.dev/selenium/web/blank.html");
	      // Add cookie into current browser context
	      driver.manage().addCookie(new Cookie("key", "value"));
    driver = webdriver.Chrome()
    driver.get("http://www.example.com")

    # Adds the cookie into current browser context
    driver.add_cookie({"name": "key", "value": "value"})
         driver.Url="https://www.selenium.dev/selenium/web/blank.html";
         // Add cookie into current browser context
         driver.Manage().Cookies.AddCookie(new Cookie("key", "value"));
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

begin
  driver.get 'https://www.example.com'
  
  # Adds the cookie into current browser context
  driver.manage.add_cookie(name: "key", value: "value")
ensure
  driver.quit
end
  
            await driver.manage().addCookie({ name: 'key', value: 'value' });
import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver

fun main() {
    val driver = ChromeDriver()
    try {
        driver.get("https://example.com")

        // Adds the cookie into current browser context
        driver.manage().addCookie(Cookie("key", "value"))
    } finally {
        driver.quit()
    }
}  
  

此方法返回与cookie名称匹配的序列化cookie数据中所有关联的cookie.

	        driver.get("https://www.selenium.dev/selenium/web/blank.html");
	        // Add cookie into current browser context
	        driver.manage().addCookie(new Cookie("foo", "bar"));
	        // Get cookie details with named cookie 'foo'
	        Cookie cookie = driver.manage().getCookieNamed("foo");
    driver = webdriver.Chrome()
    driver.get("http://www.example.com")

    # Adds the cookie into current browser context
    driver.add_cookie({"name": "foo", "value": "bar"})

    # Get cookie details with named cookie 'foo'
    print(driver.get_cookie("foo"))
         driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
         // Add cookie into current browser context
         driver.Manage().Cookies.AddCookie(new Cookie("foo", "bar"));
         // Get cookie details with named cookie 'foo'
         Cookie cookie = driver.Manage().Cookies.GetCookieNamed("foo");
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

begin
  driver.get 'https://www.example.com'
  driver.manage.add_cookie(name: "foo", value: "bar")

  # Get cookie details with named cookie 'foo'
  puts driver.manage.cookie_named('foo')
ensure
  driver.quit
end
  
            // Get cookie details with named cookie 'foo'
            await driver.manage().getCookie('foo').then(function(cookie) {
                console.log('cookie details => ', cookie);
            });
import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver

fun main() {
    val driver = ChromeDriver()
    try {
        driver.get("https://example.com")
        driver.manage().addCookie(Cookie("foo", "bar"))

        // Get cookie details with named cookie 'foo'
        val cookie = driver.manage().getCookieNamed("foo")
        println(cookie)
    } finally {
        driver.quit()
    }
}  
  

获取全部 Cookies

此方法会针对当前访问上下文返回“成功的序列化cookie数据”. 如果浏览器不再可用, 则返回错误.

	        driver.get("https://www.selenium.dev/selenium/web/blank.html");
	        // Add cookies into current browser context
	        driver.manage().addCookie(new Cookie("test1", "cookie1"));
	        driver.manage().addCookie(new Cookie("test2", "cookie2"));
	        // Get cookies
	        Set<Cookie> cookies = driver.manage().getCookies();
	         for (Cookie cookie : cookies) {
	            if (cookie.getName().equals("test1")) {
	                Assertions.assertEquals(cookie.getValue(), "cookie1");
	            }

	            if (cookie.getName().equals("test2")) {
	                Assertions.assertEquals(cookie.getValue(), "cookie2");
	            }
	         }
    driver = webdriver.Chrome()

    driver.get("http://www.example.com")

    driver.add_cookie({"name": "test1", "value": "cookie1"})
    driver.add_cookie({"name": "test2", "value": "cookie2"})

    # Get all available cookies
    print(driver.get_cookies())
         driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
         // Add cookies into current browser context
         driver.Manage().Cookies.AddCookie(new Cookie("test1", "cookie1"));
         driver.Manage().Cookies.AddCookie(new Cookie("test2", "cookie2"));
         // Get cookies
         var cookies = driver.Manage().Cookies.AllCookies;
         foreach (var cookie in cookies){
             if (cookie.Name.Equals("test1")){
                 Assert.AreEqual("cookie1", cookie.Value);
             }
             if (cookie.Name.Equals("test2")){
                 Assert.AreEqual("cookie2", cookie.Value);
             }
         }
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

begin
  driver.get 'https://www.example.com'
  driver.manage.add_cookie(name: "test1", value: "cookie1")
  driver.manage.add_cookie(name: "test2", value: "cookie2")

  # Get all available cookies
  puts driver.manage.all_cookies
ensure
  driver.quit
end
  
            await driver.manage().getCookies().then(function(cookies) {
                console.log('cookie details => ', cookies);
            });
import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver

fun main() {
    val driver = ChromeDriver()
    try {
        driver.get("https://example.com")
        driver.manage().addCookie(Cookie("test1", "cookie1"))
        driver.manage().addCookie(Cookie("test2", "cookie2"))

        // Get All available cookies
        val cookies = driver.manage().cookies
        println(cookies)
    } finally {
        driver.quit()
    }
}  
  

此方法删除与提供的cookie名称匹配的cookie数据.

	        driver.get("https://www.selenium.dev/selenium/web/blank.html");
	        driver.manage().addCookie(new Cookie("test1", "cookie1"));
	        // delete cookie named
	        driver.manage().deleteCookieNamed("test1");
    driver = webdriver.Chrome()

    driver.get("http://www.example.com")

    driver.add_cookie({"name": "test1", "value": "cookie1"})
    driver.add_cookie({"name": "test2", "value": "cookie2"})

    # Delete cookie with name 'test1'
    driver.delete_cookie("test1")
         driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
         driver.Manage().Cookies.AddCookie(new Cookie("test1", "cookie1"));
         // delete cookie named
         driver.Manage().Cookies.DeleteCookieNamed("test1");
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

begin
  driver.get 'https://www.example.com'
  driver.manage.add_cookie(name: "test1", value: "cookie1")
  driver.manage.add_cookie(name: "test2", value: "cookie2")

  # delete a cookie with name 'test1'
  driver.manage.delete_cookie('test1')
ensure
  driver.quit
end
  
            // Delete a cookie with name 'test1'
            await driver.manage().deleteCookie('test1');
import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver

fun main() {
    val driver = ChromeDriver()
    try {
        driver.get("https://example.com")
        driver.manage().addCookie(Cookie("test1", "cookie1"))
        val cookie1 = Cookie("test2", "cookie2")
        driver.manage().addCookie(cookie1)

        // delete a cookie with name 'test1'
        driver.manage().deleteCookieNamed("test1")
        
        // delete cookie by passing cookie object of current browsing context.
        driver.manage().deleteCookie(cookie1)
    } finally {
        driver.quit()
    }
}  
  

删除所有 Cookies

此方法删除当前访问上下文的所有cookie.

	        driver.get("https://www.selenium.dev/selenium/web/blank.html");
	        // Add cookies into current browser context
	        driver.manage().addCookie(new Cookie("test1", "cookie1"));
	        driver.manage().addCookie(new Cookie("test2", "cookie2"));
	        // Delete All cookies
	        driver.manage().deleteAllCookies();
    driver = webdriver.Chrome()

    driver.get("http://www.example.com")

    driver.add_cookie({"name": "test1", "value": "cookie1"})
    driver.add_cookie({"name": "test2", "value": "cookie2"})

    # Delete all cookies
    driver.delete_all_cookies()
         driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
         // Add cookies into current browser context
         driver.Manage().Cookies.AddCookie(new Cookie("test1", "cookie1"));
         driver.Manage().Cookies.AddCookie(new Cookie("test2", "cookie2"));
         // Delete All cookies
         driver.Manage().Cookies.DeleteAllCookies();
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

begin
  driver.get 'https://www.example.com'
  driver.manage.add_cookie(name: "test1", value: "cookie1")
  driver.manage.add_cookie(name: "test2", value: "cookie2")

  # deletes all cookies
  driver.manage.delete_all_cookies
ensure
  driver.quit
end
  
            // Delete all cookies
            await driver.manage().deleteAllCookies();
import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver

fun main() {
    val driver = ChromeDriver()
    try {
        driver.get("https://example.com")
        driver.manage().addCookie(Cookie("test1", "cookie1"))
        driver.manage().addCookie(Cookie("test2", "cookie2"))

        // deletes all cookies
        driver.manage().deleteAllCookies()
    } finally {
        driver.quit()
    }
}
  

Same-Site Cookie属性

此属性允许用户引导浏览器控制cookie, 是否与第三方站点发起的请求一起发送. 引入其是为了防止CSRF(跨站请求伪造)攻击.

Same-Site cookie属性接受以下两种参数作为指令

Strict:

当sameSite属性设置为 Strict, cookie不会与来自第三方网站的请求一起发送.

Lax:

当您将cookie sameSite属性设置为 Lax, cookie将与第三方网站发起的GET请求一起发送.

注意: 到目前为止, 此功能已在Chrome(80+版本), Firefox(79+版本)中提供, 并适用于Selenium 4以及更高版本.

        val cookie = Cookie.Builder("key", "value").sameSite("Strict").build()
        val cookie1 = Cookie.Builder("key", "value").sameSite("Lax").build()
        driver.manage().addCookie(cookie)
        driver.manage().addCookie(cookie1)
        println(cookie.getSameSite())
        println(cookie1.getSameSite())
    } finally {
        driver.quit()
    }
} 
  

4 - 与IFrames和frames一起工作

框架是一种现在已被弃用的方法,用于从同一域中的多个文档构建站点布局。除非你使用的是 HTML5 之前的 webapp,否则你不太可能与他们合作。内嵌框架允许插入来自完全不同领域的文档,并且仍然经常使用。

如果您需要使用框架或 iframe, WebDriver 允许您以相同的方式使用它们。考虑 iframe 中的一个按钮。 如果我们使用浏览器开发工具检查元素,我们可能会看到以下内容:

<div id="modal">
  <iframe id="buttonframe"name="myframe"src="https://seleniumhq.github.io">
   <button>Click here</button>
 </iframe>
</div>

如果不是 iframe,我们可能会使用如下方式点击按钮:

// 这不会工作
driver.findElement(By.tagName("button")).click();
    # 这不会工作
driver.find_element(By.TAG_NAME, 'button').click()
// 这不会工作
driver.FindElement(By.TagName("button")).Click();
    # 这不会工作
driver.find_element(:tag_name,'button').click
// 这不会工作
await driver.findElement(By.css('button')).click();
// 这不会工作
driver.findElement(By.tagName("button")).click()

但是,如果 iframe 之外没有按钮,那么您可能会得到一个 no such element 无此元素 的错误。 这是因为 Selenium 只知道顶层文档中的元素。为了与按钮进行交互,我们需要首先切换到框架, 这与切换窗口的方式类似。WebDriver 提供了三种切换到帧的方法。

使用 WebElement

使用 WebElement 进行切换是最灵活的选择。您可以使用首选的选择器找到框架并切换到它。

         //switch To IFrame using Web Element
         WebElement iframe = driver.findElement(By.id("iframe1"));
         //Switch to the frame
         driver.switchTo().frame(iframe);
         assertEquals(true, driver.getPageSource().contains("We Leave From Here"));
         //Now we can type text into email field
         WebElement emailE= driver.findElement(By.id("email"));
         emailE.sendKeys("admin@selenium.dev");
         emailE.clear();
    # 存储网页元素
iframe = driver.find_element(By.CSS_SELECTOR, "#modal > iframe")

    # 切换到选择的 iframe
driver.switch_to.frame(iframe)

    # 单击按钮
driver.find_element(By.TAG_NAME, 'button').click()
            //switch To IFrame using Web Element
            IWebElement iframe = driver.FindElement(By.Id("iframe1"));
            //Switch to the frame
            driver.SwitchTo().Frame(iframe);
            Assert.AreEqual(true, driver.PageSource.Contains("We Leave From Here"));
            //Now we can type text into email field
            IWebElement emailE = driver.FindElement(By.Id("email"));
            emailE.SendKeys("admin@selenium.dev");
            emailE.Clear();
    # Store iframe web element
iframe = driver.find_element(:css,'#modal> iframe')

    # 切换到 frame
driver.switch_to.frame iframe

    # 单击按钮
driver.find_element(:tag_name,'button').click
// 存储网页元素
const iframe = driver.findElement(By.css('#modal> iframe'));

// 切换到 frame
await driver.switchTo().frame(iframe);

// 现在可以点击按钮
await driver.findElement(By.css('button')).click();
// 存储网页元素
val iframe = driver.findElement(By.cssSelector("#modal>iframe"))

// 切换到 frame
driver.switchTo().frame(iframe)

// 现在可以点击按钮
driver.findElement(By.tagName("button")).click()

使用 name 或 id

如果您的 frame 或 iframe 具有 id 或 name 属性,则可以使用该属性。如果名称或 id 在页面上不是唯一的, 那么将切换到找到的第一个。

         //switch To IFrame using name or id
         driver.findElement(By.name("iframe1-name"));
         //Switch to the frame
         driver.switchTo().frame(iframe);
         assertEquals(true, driver.getPageSource().contains("We Leave From Here"));
         WebElement email=driver.findElement(By.id("email"));
         //Now we can type text into email field
         email.sendKeys("admin@selenium.dev");
         email.clear();
    # 通过 id 切换框架
driver.switch_to.frame('buttonframe')

    # 单击按钮
driver.find_element(By.TAG_NAME, 'button').click()
            //switch To IFrame using name or id
            driver.FindElement(By.Name("iframe1-name"));
            //Switch to the frame
            driver.SwitchTo().Frame(iframe);
            Assert.AreEqual(true, driver.PageSource.Contains("We Leave From Here"));
            IWebElement email = driver.FindElement(By.Id("email"));
            //Now we can type text into email field
            email.SendKeys("admin@selenium.dev");
            email.Clear();
    # Switch by ID
driver.switch_to.frame 'buttonframe'

    # 单击按钮
driver.find_element(:tag_name,'button').click
// 使用 ID
await driver.switchTo().frame('buttonframe');

// 或者使用 name 代替
await driver.switchTo().frame('myframe');

// 现在可以点击按钮
await driver.findElement(By.css('button')).click();
// 使用 ID
driver.switchTo().frame("buttonframe")

// 或者使用 name 代替
driver.switchTo().frame("myframe")

// 现在可以点击按钮
driver.findElement(By.tagName("button")).click()

使用索引

还可以使用frame的索引, 例如可以使用JavaScript中的 window.frames 进行查询.

         //switch To IFrame using index
         driver.switchTo().frame(0);
    # 切换到第 2 个框架
driver.switch_to.frame(1)
            //switch To IFrame using index
            driver.SwitchTo().Frame(0);
    # 基于索引切换到第 2 个 iframe
iframe = driver.find_elements(By.TAG_NAME,'iframe')[1]

    # 切换到选择的 iframe
driver.switch_to.frame(iframe)
// 切换到第 2 个框架
await driver.switchTo().frame(1);
// 切换到第 2 个框架
driver.switchTo().frame(1)

离开框架

离开 iframe 或 frameset,切换回默认内容,如下所示:

         //leave frame
         driver.switchTo().defaultContent();
    # 切回到默认内容
driver.switch_to.default_content()
            //leave frame
            driver.SwitchTo().DefaultContent();
    # 回到顶层
driver.switch_to.default_content
// 回到顶层
await driver.switchTo().defaultContent();
// 回到顶层
driver.switchTo().defaultContent()

5 - 打印页面

无论是共享信息还是维护档案,打印网页都是一项常见任务。 Selenium 通过其 PrintOptions、PrintsPage 和 browsingContext 类简化了这一过程,这些类为网页自动打印提供了灵活直观的接口。 这些类使得用户可以配置打印首选项,如页面布局、页边距和缩放比例,以确保输出满足特定要求。

配置

方向

通过 getOrientation()setOrientation() 方法,可以获取/设置页面方向(PORTRAITLANDSCAPE)。

    public void TestOrientation() 
    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setOrientation(PrintOptions.Orientation.LANDSCAPE);
        PrintOptions.Orientation current_orientation = printOptions.getOrientation();
    }
        public void TestOrientation()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://selenium.dev");
            PrintOptions printOptions  = new PrintOptions();
            printOptions.Orientation = PrintOrientation.Landscape;
            PrintOrientation currentOrientation = printOptions.Orientation;
        }
def test_orientation(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.orientation = "landscape" ## landscape or portrait
    assert print_options.orientation == "landscape"

范围

通过 getPageRanges()setPageRanges() 方法,可以获取设置要打印页面的范围(如 “2-4”)。

    public void TestRange() 
    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setPageRanges("1-2");
        String[] current_range = printOptions.getPageRanges();
    }
        public void TestRange()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://selenium.dev");
            PrintOptions printOptions  = new PrintOptions();
            printOptions.AddPageRangeToPrint("1-3"); // add range of pages
            printOptions.AddPageToPrint(5); // add individual page
        }   
def test_range(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.page_ranges = ["1, 2, 3"] ## ["1", "2", "3"] or ["1-3"]
    assert print_options.page_ranges == ["1, 2, 3"]

尺寸

通过 getPaperSize()setPaperSize() 方法,可以获取/设置要打印页面的纸张尺寸(如"A0"、“A6”、“Legal”、“Tabloid” 等)。

    public void TestSize() 
    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setScale(.50);
        double current_scale = printOptions.getScale();
    }
        public void TestSize()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://www.selenium.dev/");
            PrintOptions printOptions = new PrintOptions();
            PrintOptions.PageSize currentDimensions = printOptions.PageDimensions;
        }
def test_size(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.scale = 0.5 ## 0.1 to 2.0``
    assert print_options.scale == 0.5

边距

通过 getPageMargin()setPageMargin() 方法,可以获取/设置要打印页面的边距大小(也就是上、下、左右边距)。

    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        PageMargin margins = new PageMargin(1.0,1.0,1.0,1.0);
        printOptions.setPageMargin(margins);
        double topMargin = margins.getTop();
        double bottomMargin = margins.getBottom();
        double leftMargin = margins.getLeft();
        double rightMargin = margins.getRight();
    }
        public void TestMargins()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://www.selenium.dev/");
            PrintOptions printOptions = new PrintOptions();
            PrintOptions.Margins currentMargins = printOptions.PageMargins;
        }
def test_margin(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.margin_top = 10
    print_options.margin_bottom = 10
    print_options.margin_left = 10
    print_options.margin_right = 10
    assert print_options.margin_top == 10
    assert print_options.margin_bottom == 10
    assert print_options.margin_left == 10
    assert print_options.margin_right == 10

缩放

通过 getScale()setScale() 方法,可以获取/设置要打印页面的缩放尺寸(如 1.0 为 100% 或默认缩放,0.25 为 25% 等)。

    public void TestScale() 
    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setScale(.50);
        double current_scale = printOptions.getScale();
    }
        public void TestScale()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://www.selenium.dev/");
            PrintOptions printOptions = new PrintOptions();
            printOptions.ScaleFactor = 0.5;
            double currentScale = printOptions.ScaleFactor;
        }
def test_scale(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.scale = 0.5 ## 0.1 to 2.0
    current_scale = print_options.scale
    assert current_scale == 0.5

背景

通过 getBackground()setBackground() 方法,可以获取/设置背景色和图片出现,其为布尔值 truefalse

    public void TestBackground() 
    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setBackground(true);
        boolean current_background = printOptions.getBackground();
    }
        public void TestBackgrounds()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://www.selenium.dev/");
            PrintOptions printOptions = new PrintOptions();
            printOptions.OutputBackgroundImages = true;
            bool currentBackgrounds = printOptions.OutputBackgroundImages;
        }
def test_background(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.background = True ## True or False
    assert print_options.background is True

缩放至合适大小

通过 getShrinkToFit()setShrinkToFit() 方法,可以获取/设置页面是否会根据页面内容缩小,其为布尔值 truefalse

    public void TestShrinkToFit() 
    {
        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setShrinkToFit(true);
        boolean current_shrink_to_fit = printOptions.getShrinkToFit();
    }
        public void TestShrinkToFit()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://www.selenium.dev/");
            PrintOptions printOptions = new PrintOptions();
            printOptions.ShrinkToFit = true;
            bool currentShrinkToFit = printOptions.ShrinkToFit;
        }
def test_shrink_to_fit(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    print_options.shrink_to_fit = True ## True or False
    assert print_options.shrink_to_fit is True

打印

配置好打印选项后,就可以打印页面了。为此,您可以调用打印功能,生成网页的 PDF 表示形式。 生成的 PDF 文件可以保存到本地存储器中,以便进一步使用或分发。 使用 PrintsPage() 时,打印命令将以 base64 编码格式返回 PDF 数据,该格式可以解码并写入所需位置的文件,而使用 BrowsingContext() 时将返回字符串。

目前可能有多种实现方式,这取决于您所选择的语言。例如,Java 可以使用 BrowingContext()PrintsPage() 进行打印。两者都将 PrintOptions() 对象作为一个参数。

注意:BrowsingContext() 是 Selenium BiDi 实现的一部分。为启用 BiDi,请参见启用 Bidi

PrintsPage()

    public void PrintWithPrintsPageTest() 
    {
        driver.get("https://www.selenium.dev/");
        PrintsPage printer = (PrintsPage) driver;
        PrintOptions printOptions = new PrintOptions();
        Pdf printedPage = printer.print(printOptions);
        Assertions.assertNotNull(printedPage);
    }

BrowsingContext()

    public void PrintWithBrowsingContextTest() 
    {
        BrowsingContext browsingContext = new BrowsingContext(driver, driver.getWindowHandle());
        driver.get("https://www.selenium.dev/selenium/web/formPage.html");
        PrintOptions printOptions = new PrintOptions();
        String printPage = browsingContext.print(printOptions);
        Assertions.assertTrue(printPage.length() > 0);
    }

print_page()

def test_prints_page(driver):
    driver.get("https://www.selenium.dev/")
    print_options = PrintOptions()
    pdf = driver.print_page(print_options)
    assert len(pdf) > 0

6 - 同窗口和标签一起工作

窗口和标签页

WebDriver 没有区分窗口和标签页。如果你的站点打开了一个新标签页或窗口,Selenium 将允许您使用窗口句柄来处理它。 每个窗口都有一个唯一的标识符,该标识符在单个会话中保持持久性。你可以使用以下方法获得当前窗口的窗口句柄:

        // Navigate to Url
        driver.get("https://www.selenium.dev/selenium/web/window_switching_tests/page_with_frame.html");
        //fetch handle of this
        String currHandle=driver.getWindowHandle();
        assertNotNull(currHandle);
driver.current_window_handle
driver.window_handle
await driver.getWindowHandle();
driver.windowHandle

切换窗口或标签页

单击在 <a href=“https://seleniumhq.github.io"target="_blank”>新窗口 中打开链接, 则屏幕会聚焦在新窗口或新标签页上,但 WebDriver 不知道操作系统认为哪个窗口是活动的。 要使用新窗口,您需要切换到它。 如果只有两个选项卡或窗口被打开,并且你知道从哪个窗口开始, 则你可以遍历 WebDriver, 通过排除法可以看到两个窗口或选项卡,然后切换到你需要的窗口或选项卡。

不过,Selenium 4 提供了一个新的 api NewWindow 它创建一个新选项卡 (或) 新窗口并自动切换到它。

        //click on link to open a new window
        driver.findElement(By.linkText("Open new window")).click();
        //fetch handles of all windows, there will be two, [0]- default, [1] - new window
        Object[] windowHandles=driver.getWindowHandles().toArray();
        driver.switchTo().window((String) windowHandles[1]);
        //assert on title of new window
        String title=driver.getTitle();
        assertEquals("Simple Page",title);
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

    # 启动驱动程序
with webdriver.Firefox() as driver:
    # 打开网址
driver.get("https://seleniumhq.github.io")

    # 设置等待
    wait = WebDriverWait(driver, 10)

    # 存储原始窗口的 ID
    original_window = driver.current_window_handle

    # 检查一下,我们还没有打开其他的窗口
    assert len(driver.window_handles) == 1

    # 单击在新窗口中打开的链接
    driver.find_element(By.LINK_TEXT, "new window").click()

    # 等待新窗口或标签页
    wait.until(EC.number_of_windows_to_be(2))

    # 循环执行,直到找到一个新的窗口句柄
    for window_handle in driver.window_handles:
        if window_handle != original_window:
            driver.switch_to.window(window_handle)
            break

    # 等待新标签页完成加载内容
    wait.until(EC.title_is("SeleniumHQ Browser Automation"))
    # 存储原始窗口的 ID
original_window = driver.window_handle

    #检查一下,我们还没有打开其他的窗口
assert(driver.window_handles.length == 1,'Expected one window')

    #点击在新窗口中打开的链接
driver.find_element(link:'new window').click

    #等待新窗口或标签页
wait.until {driver.window_handles.length == 2}

    #循环执行,直到找到一个新的窗口句柄
driver.window_handles.each do |handle|
if handle != original_window
driver.switch_to.window handle
break
end
end

    #等待新标签页完成加载内容
wait.until {driver.title =='Selenium documentation'}
// 存储原始窗口的 ID
const originalWindow = await driver.getWindowHandle();

// 检查一下,我们还没有打开其他的窗口
assert((await driver.getAllWindowHandles()).length === 1);

// 点击在新窗口中打开的链接
await driver.findElement(By.linkText('new window')).click();

// 等待新窗口或标签页
await driver.wait(async () => (await driver.getAllWindowHandles()).length === 2,
10000
);

// 循环执行,直到找到一个新的窗口句柄
const windows = await driver.getAllWindowHandles();
windows.forEach(async handle => {if (handle !== originalWindow) {await driver.switchTo().window(handle);
}
});

// 等待新标签页完成加载内容
await driver.wait(until.titleIs('Selenium documentation'), 10000);
// 存储原始窗口的 ID
val originalWindow = driver.getWindowHandle()

// 检查一下,我们还没有打开其他的窗口
assert(driver.getWindowHandles().size() === 1)

// 点击在新窗口中打开的链接
driver.findElement(By.linkText("new window")).click()

// 等待新窗口或标签页
wait.until(numberOfWindowsToBe(2))

// 循环执行,直到找到一个新的窗口句柄
for (windowHandle in driver.getWindowHandles()) {
if (!originalWindow.contentEquals(windowHandle)) {
driver.switchTo().window(windowHandle)
break
}
}

// 等待新标签页完成加载内容
wait.until(titleIs("Selenium documentation"))

关闭窗口或标签页

当你完成了一个窗口或标签页的工作时,_并且_它不是浏览器中最后一个打开的窗口或标签页时,你应该关闭它并切换回你之前使用的窗口。 假设您遵循了前一节中的代码示例,您将把前一个窗口句柄存储在一个变量中。把这些放在一起,你会得到:

        //closing current window
        driver.close();
        //Switch back to the old tab or window
        driver.switchTo().window((String) windowHandles[0]);
    #关闭标签页或窗口
driver.close()

    #切回到之前的标签页或窗口
driver.switch_to.window(original_window)
    #关闭标签页或窗口
driver.close

    #切回到之前的标签页或窗口
driver.switch_to.window original_window
//关闭标签页或窗口
await driver.close();

//切回到之前的标签页或窗口
await driver.switchTo().window(originalWindow);
//关闭标签页或窗口
driver.close()

//切回到之前的标签页或窗口
driver.switchTo().window(originalWindow)

如果在关闭一个窗口后忘记切换回另一个窗口句柄,WebDriver 将在当前关闭的页面上执行,并触发一个 No Such Window Exception 无此窗口异常。必须切换回有效的窗口句柄才能继续执行。

创建新窗口(或)新标签页并且切换

创建一个新窗口 (或) 标签页,屏幕焦点将聚焦在新窗口或标签在上。您不需要切换到新窗口 (或) 标签页。如果除了新窗口之外, 您打开了两个以上的窗口 (或) 标签页,您可以通过遍历 WebDriver 看到两个窗口或选项卡,并切换到非原始窗口。

注意: 该特性适用于 Selenium 4 及其后续版本。

        //Opens a new tab and switches to new tab
        driver.switchTo().newWindow(WindowType.TAB);
        assertEquals("",driver.getTitle());
        
        //Opens a new window and switches to new window
        driver.switchTo().newWindow(WindowType.WINDOW);
        assertEquals("",driver.getTitle());
    # 打开新标签页并切换到新标签页
driver.switch_to.new_window('tab')

    # 打开一个新窗口并切换到新窗口
driver.switch_to.new_window('window')

打开新标签页并切换到新标签页

    driver.switch_to.new_window(:tab)

打开一个新窗口并切换到新窗口

    driver.switch_to.new_window(:window)
// 打开新标签页并切换到新标签页
// 打开一个新窗口并切换到新窗口
// 打开新标签页并切换到新标签页
driver.switchTo().newWindow(WindowType.TAB)

// 打开一个新窗口并切换到新窗口
driver.switchTo().newWindow(WindowType.WINDOW)

在会话结束时退出浏览器

当你完成了浏览器会话,你应该调用 quit 退出,而不是 close 关闭:

        //quitting driver
        driver.quit(); //close all windows
driver.quit()
driver.quit
await driver.quit();
driver.quit()

  • 退出将会
    • 关闭所有与 WebDriver 会话相关的窗口和选项卡
    • 结束浏览器进程
    • 结束后台驱动进程
    • 通知 Selenium Grid 浏览器不再使用,以便可以由另一个会话使用它(如果您正在使用 Selenium Grid)

调用 quit() 失败将留下额外的后台进程和端口运行在机器上,这可能在以后导致一些问题。

有的测试框架提供了一些方法和注释,您可以在测试结束时放入 teardown() 方法中。

/**
* 使用 JUnit 的例子
* https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/AfterAll.html
*/
@AfterAll
public static void tearDown() {
    driver.quit();
}
    # unittest teardown

如果不在测试上下文中运行 WebDriver,您可以考虑使用 try / finally,这是大多数语言都提供的, 这样一个异常处理仍然可以清理 WebDriver 会话。

try {
    //WebDriver 代码…
} finally {
    driver.quit();
}
try:
    #WebDriver 代码…
finally:
driver.quit()
try {//WebDriver 代码…} finally {driver.Quit();
}
begin
    #WebDriver 代码…
ensure
driver.quit
end
try {//WebDriver 代码…} finally {await driver.quit();
}
try {//WebDriver 代码…} finally {driver.quit()
}

Python 的 WebDriver 现在支持 Python 上下文管理器,当使用 with 关键字时,可以在执行结束时自动退出驱动程序。

with webdriver.Firefox() as driver:
  # WebDriver 代码…

# 在此缩进位置后 WebDriver 会自动退出

窗口管理

屏幕分辨率会影响 web 应用程序的呈现方式,因此 WebDriver 提供了移动和调整浏览器窗口大小的机制。

获取窗口大小

获取浏览器窗口的大小(以像素为单位)。

// 分别获取每个尺寸
int width = driver.manage().window().getSize().getWidth();
int height = driver.manage().window().getSize().getHeight();

// 或者存储尺寸并在以后查询它们
Dimension size = driver.manage().window().getSize();
int width1 = size.getWidth();
int height1 = size.getHeight();
    # 分别获取每个尺寸
width = driver.get_window_size().get("width")
height = driver.get_window_size().get("height")

    # 或者存储尺寸并在以后查询它们
size = driver.get_window_size()
width1 = size.get("width")
height1 = size.get("height")
// 分别获取每个尺寸
int width = driver.Manage().Window.Size.Width;
int height = driver.Manage().Window.Size.Height;

// 或者存储尺寸并在以后查询它们
System.Drawing.Size size = driver.Manage().Window.Size;
int width1 = size.Width;
int height1 = size.Height;
    # 分别获取每个尺寸
width = driver.manage.window.size.width
height = driver.manage.window.size.height

    # 或者存储尺寸并在以后查询它们
size = driver.manage.window.size
width1 = size.width
height1 = size.height
分别获取每个尺寸
或者存储尺寸并在以后查询它们
// 分别获取每个尺寸
val width = driver.manage().window().size.width
val height = driver.manage().window().size.height

// 或者存储尺寸并在以后查询它们
val size = driver.manage().window().size
val width1 = size.width
val height1 = size.height

设置窗口大小

恢复窗口并设置窗口大小。

driver.manage().window().setSize(new Dimension(1024, 768));
driver.set_window_size(1024, 768)
driver.Manage().Window.Size = new Size(1024, 768);
driver.manage.window.resize_to(1024,768)
await driver.manage().window().setRect({width: 1024, height: 768});
driver.manage().window().size = Dimension(1024, 768)

得到窗口的位置

获取浏览器窗口左上角的坐标。

// 分别获取每个尺寸
int x = driver.manage().window().getPosition().getX();
int y = driver.manage().window().getPosition().getY();

// 或者存储尺寸并在以后查询它们
Point position = driver.manage().window().getPosition();
int x1 = position.getX();
int y1 = position.getY();
    # 分别获取每个尺寸
x = driver.get_window_position().get('x')
y = driver.get_window_position().get('y')

    # 或者存储尺寸并在以后查询它们
position = driver.get_window_position()
x1 = position.get('x')
y1 = position.get('y')
// 分别获取每个尺寸
int x = driver.Manage().Window.Position.X;
int y = driver.Manage().Window.Position.Y;

// 或者存储尺寸并在以后查询它们
Point position = driver.Manage().Window.Position;
int x1 = position.X;
int y1 = position.Y;
    #Access each dimension individually
x = driver.manage.window.position.x
y = driver.manage.window.position.y

    # Or store the dimensions and query them later
rect  = driver.manage.window.rect
x1 = rect.x
y1 = rect.y
分别获取每个尺寸
或者存储尺寸并在以后查询它们
// 分别获取每个尺寸
val x = driver.manage().window().position.x
val y = driver.manage().window().position.y

// 或者存储尺寸并在以后查询它们
val position = driver.manage().window().position
val x1 = position.x
val y1 = position.y

设置窗口位置

将窗口移动到设定的位置。

// 将窗口移动到主显示器的左上角
driver.manage().window().setPosition(new Point(0, 0));
    # 将窗口移动到主显示器的左上角
driver.set_window_position(0, 0)
// 将窗口移动到主显示器的左上角
driver.Manage().Window.Position = new Point(0, 0);
driver.manage.window.move_to(0,0)
// 将窗口移动到主显示器的左上角
await driver.manage().window().setRect({x: 0, y: 0});
// 将窗口移动到主显示器的左上角
driver.manage().window().position = Point(0,0)

最大化窗口

扩大窗口。对于大多数操作系统,窗口将填满屏幕,而不会阻挡操作系统自己的菜单和工具栏。

driver.manage().window().maximize();
driver.maximize_window()
driver.Manage().Window.Maximize();
driver.manage.window.maximize
await driver.manage().window().maximize();
driver.manage().window().maximize()

最小化窗口

最小化当前浏览上下文的窗口. 这种命令的精准行为将作用于各个特定的窗口管理器.

最小化窗口通常将窗口隐藏在系统托盘中.

注意: 此功能适用于Selenium 4以及更高版本.

driver.manage().window().minimize();
driver.minimize_window()
driver.Manage().Window.Minimize();
driver.manage.window.minimize
await driver.manage().window().minimize();
driver.manage().window().minimize()

全屏窗口

填充整个屏幕,类似于在大多数浏览器中按下 F11。

driver.manage().window().fullscreen();
driver.fullscreen_window()
driver.Manage().Window.FullScreen();
driver.manage.window.full_screen
await driver.manage().window().fullscreen();
driver.manage().window().fullscreen()

屏幕截图

7 - 虚拟身份验证器

一种Web身份验证器模型的表示形式.

Web 应用程序可以启用基于公钥的身份验证机制(称为 Web 身份验证)以无密码方式对用户进行身份验证。 Web 身份验证 定义了允许用户创建公钥凭据并将其注册到身份验证器的 API。 身份验证器可以是硬件设备或软件实体,用于存储用户的公钥凭证并根据请求检索它们。

顾名思义,虚拟身份验证器模拟此类身份验证器进行测试。

虚拟身份验证器选项

虚拟身份验证器具有 一组属性。 这些属性在 Selenium 绑定中映射为 VirtualAuthenticatorOptions。

    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
      .setIsUserVerified(true)
      .setHasUserVerification(true)
      .setIsUserConsenting(true)
      .setTransport(VirtualAuthenticatorOptions.Transport.USB)
      .setProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
      .setHasResidentKey(false);
            // Create virtual authenticator options
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetIsUserVerified(true)
                .SetHasUserVerification(true)
                .SetIsUserConsenting(true)
                .SetTransport(VirtualAuthenticatorOptions.Transport.USB)
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);
    options = VirtualAuthenticatorOptions()
    options.is_user_verified = True
    options.has_user_verification = True
    options.is_user_consenting = True
    options.transport = VirtualAuthenticatorOptions.Transport.USB
    options.protocol = VirtualAuthenticatorOptions.Protocol.U2F
    options.has_resident_key = False
      options = new VirtualAuthenticatorOptions();
      options.setIsUserVerified(true);
      options.setHasUserVerification(true);
      options.setIsUserConsenting(true);
      options.setTransport(Transport['USB']);
      options.setProtocol(Protocol['U2F']);
      options.setHasResidentKey(false);

添加虚拟身份验证器

它使用提供的属性创建一个新的虚拟身份验证器。

    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
      .setProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
      .setHasResidentKey(false);

    VirtualAuthenticator authenticator =
      ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(options);
            // Create virtual authenticator options
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);

            // Register a virtual authenticator
            ((WebDriver)driver).AddVirtualAuthenticator(options);

            List<Credential> credentialList = ((WebDriver)driver).GetCredentials();
    options = VirtualAuthenticatorOptions()
    options.protocol = VirtualAuthenticatorOptions.Protocol.U2F
    options.has_resident_key = False

    # Register a virtual authenticator
    driver.add_virtual_authenticator(options)
            options.setProtocol(Protocol['U2F']);
            options.setHasResidentKey(false);

            // Register a virtual authenticator
            await driver.addVirtualAuthenticator(options);

删除虚拟身份验证器

删除之前添加的虚拟身份验证器。

    ((HasVirtualAuthenticator) driver).removeVirtualAuthenticator(authenticator);
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetProtocol(VirtualAuthenticatorOptions.Protocol.U2F)
                .SetHasResidentKey(false);

            String virtualAuthenticatorId = ((WebDriver)driver).AddVirtualAuthenticator(options);

            ((WebDriver)driver).RemoveVirtualAuthenticator(virtualAuthenticatorId);
    options = VirtualAuthenticatorOptions()

    # Register a virtual authenticator
    driver.add_virtual_authenticator(options)

    # Remove virtual authenticator
    driver.remove_virtual_authenticator()
            await driver.addVirtualAuthenticator(options);
            await driver.removeVirtualAuthenticator();

    rp_id = "localhost"
    user_handle = bytearray({1})
    privatekey = urlsafe_b64decode(BASE64__ENCODED_PK)
    sign_count = 0

    # create a  resident credential using above parameters
    resident_credential = Credential.create_resident_credential(credential_id, rp_id, user_handle, privatekey, sign_count)
            options.setProtocol(Protocol['CTAP2']);
            options.setHasResidentKey(true);
            options.setHasUserVerification(true);
            options.setIsUserVerified(true);

            await driver.addVirtualAuthenticator(options);

            let residentCredential = new Credential().createResidentCredential(
                new Uint8Array([1, 2, 3, 4]),
                'localhost',
                new Uint8Array([1]),
                Buffer.from(BASE64_ENCODED_PK, 'base64').toString('binary'),
                0);

            await driver.addCredential(residentCredential);

创建临时凭据

使用给定的所需凭据 参数 创建一个常驻(无状态)凭据。

    byte[] credentialId = {1, 2, 3, 4};
    Credential nonResidentCredential = Credential.createNonResidentCredential(
      credentialId, "localhost", ec256PrivateKey, /*signCount=*/0);
            byte[] credentialId = { 1, 2, 3, 4 };

            Credential nonResidentCredential = Credential.CreateNonResidentCredential(
              credentialId, "localhost", base64EncodedEC256PK, 0);
    # parameters for Non Resident Credential
    credential_id = bytearray({1, 2, 3, 4})
    rp_id = "localhost"
    privatekey = urlsafe_b64decode(BASE64__ENCODED_PK)
    sign_count = 0

    # create a non resident credential using above parameters
    credential = Credential.create_non_resident_credential(credential_id, rp_id, privatekey, sign_count)
            let nonResidentCredential = new Credential().createNonResidentCredential(
                new Uint8Array([1, 2, 3, 4]),
                'localhost',
                Buffer.from(base64EncodedPK, 'base64').toString('binary'),
                0);

                'localhost',
                new Uint8Array([1]),
                Buffer.from(BASE64_ENCODED_PK, 'base64').toString('binary'),
                0);

            await driver.addCredential(residentCredential);

            let credentialList = await driver.getCredentials();

删除凭据

根据传递的凭据ID从身份验证器中删除凭据。

            ((WebDriver)driver).AddVirtualAuthenticator(new VirtualAuthenticatorOptions());

            byte[] credentialId = { 1, 2, 3, 4 };

            Credential nonResidentCredential = Credential.CreateNonResidentCredential(
              credentialId, "localhost", base64EncodedEC256PK, 0);

            ((WebDriver)driver).AddCredential(nonResidentCredential);

            ((WebDriver)driver).RemoveCredential(credentialId);
    VirtualAuthenticator authenticator =
      ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(new VirtualAuthenticatorOptions());

    byte[] credentialId = {1, 2, 3, 4};
    Credential credential = Credential.createNonResidentCredential(
      credentialId, "localhost", rsaPrivateKey, 0);

    authenticator.addCredential(credential);

    authenticator.removeCredential(credentialId);
    driver.remove_credential(credential.id)

删除所有凭据

从身份验证器中删除所有凭据。

    VirtualAuthenticator authenticator =
      ((HasVirtualAuthenticator) driver).addVirtualAuthenticator(new VirtualAuthenticatorOptions());

    byte[] credentialId = {1, 2, 3, 4};
    Credential residentCredential = Credential.createNonResidentCredential(
      credentialId, "localhost", rsaPrivateKey, /*signCount=*/0);

    authenticator.addCredential(residentCredential);

    authenticator.removeAllCredentials();
            ((WebDriver)driver).AddVirtualAuthenticator(new VirtualAuthenticatorOptions());

            byte[] credentialId = { 1, 2, 3, 4 };

            Credential nonResidentCredential = Credential.CreateNonResidentCredential(
              credentialId, "localhost", base64EncodedEC256PK, 0);

            ((WebDriver)driver).AddCredential(nonResidentCredential);

            ((WebDriver)driver).RemoveAllCredentials();
    driver.remove_all_credentials()
            await driver.addVirtualAuthenticator(options);

            let nonResidentCredential = new Credential().createNonResidentCredential(
                new Uint8Array([1, 2, 3, 4]),
                'localhost',
                Buffer.from(BASE64_ENCODED_PK, 'base64').toString('binary'),
                0);

            await driver.addCredential(nonResidentCredential);
            driver.removeAllCredentials();

设置用户验证状态

设置身份验证器是模拟用户验证成功还是失败。

    VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
      .setIsUserVerified(true);
            VirtualAuthenticatorOptions options = new VirtualAuthenticatorOptions()
                .SetIsUserVerified(true);
    # Create virtual authenticator options
    options = VirtualAuthenticatorOptions()
    options.is_user_verified = True
}, { browsers: [Browser.CHROME]});
