我想在我的 selenium chromedriver 项目中使用 2 个实验选项，但我没有获得有关“add_experimental_option”函数的足够信息，我想使用 2 个实验选项“prefs”和“debuggerAddress”，当我尝试运行它时，报错，只能用一个，怎么两个都用？

opt = Options()
opt.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
opt.add_experimental_option("prefs", { \
    "profile.managed_default_content_settings.images": 2
})

错误信息

ChromeOptions 对象

  • prefs [type: dictionary]：一个字典，每个条目都包含首选项的名称及其值。这些首选项仅适用于正在使用的用户配置文件。

  • debuggerAddress [type: string] : 要连接的 Chrome 调试器服务器的地址，格式为 <hostname/ip:port>，例如 '127.0.0.1:38947'

experimental_option您可以按如下方式添加两者：

opt = webdriver.ChromeOptions()
prefs = {"profile.managed_default_content_settings.images" : 2}
opt.add_experimental_option("prefs", prefs)
opt.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', options=opt, service_log_path='NUL')
