硒铬使用多个add_experimental_option

Question

我想在我的硒chromedriver项目上使用两个实验选项，但我没有得到足够的关于"add_experimental_option"函数，我想使用2个实验选项"；prefs"；以及"；debuggerAddress"；，当我尝试运行它时，它会出错，我只能使用其中一个，我怎么能同时使用它们呢？

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

错误消息

ChromeOptions对象

• prefs〔type：dictionary〕：一个字典，每个条目都由首选项的名称及其值组成。这些首选项仅应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">

您可以按如下方式添加两个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:pathtochromedriver.exe', options=opt, service_log_path='NUL')
