Selenium chrome 使用多个 add_experimental_option

Question

我想在我的 selenium chromedriver 项目上使用 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，它出现错误，我只能使用其中一个，我如何才能同时使用它们？

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

Answer 1

ChromeOptions objects

prefs [类型：字典]：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个人资料。
debuggerAddress [类型：字符串]：要连接的 Chrome 调试器服务器的地址，格式为，例如'127.0.0.1:38947'

您可以按如下方式添加 experimental_option：

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')
