Chrome 特定功能
特定于 Google Chrome 浏览器的功能和特性.
默认情况下，Selenium 4与Chrome v75及更高版本兼容. 但是请注意Chrome浏览器的版本与chromedriver的主版本需要匹配.
Options
所有浏览器的通用功能请看这 Options page.
Chrome浏览器的特有功能可以在谷歌的页面找到: Capabilities & ChromeOptions
基于默认选项的Chrome浏览器会话看起来是这样:

日志级别
共有六种日志级别: ALL, DEBUG, INFO, WARNING, SEVERE, 以及 OFF.
注意 --verbose 等效于 --log-level=ALL 以及 --silent 等效于 --log-level=OFF,
因此, 此示例只是通用地设置日志级别:

日志文件功能
有 2 个功能仅在写入文件时可用:
- 追加日志
- 可读时间戳
要使用它们, 您还需要显式指定日志路径和日志级别. 日志输出将由驱动程序管理, 而不是由进程管理, 因此可能会看到细微的差异.

禁用构建检查
Chromedriver 和 Chrome 浏览器版本应该匹配, 如果它们不匹配, 驱动程序将出错. 如果您停用构建检查功能, 则可以强制将驱动程序与任何版本的 Chrome 一起使用. 请注意, 这是一项不受支持的功能, 并且不会调查 bug.
