如何在pythonselenium中设置Chrome实验选项same-site-by-default-cookie

Question

我想这应该工作：

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option('same-site-by-default-cookies', 'true')
driver = webdriver.Chrome(chrome_options=options)

启用为将来的chrome版本安排的samesite cookie限制。不是，有错误：

selenium.common.exceptions.InvalidArgumentException: 
Message: invalid argument: cannot parse capability: goog:chromeOptions
from invalid argument: unrecognized chrome option: same-site-by-default-cookies

我可以使用chrome：// flags手动更改选项，然后查看它是否有效。但是，我想使其自动化，然后运行测试脚本来查看它。

这里有Java代码：https :

cI8hj7eihRo 可以做到，但是我不确定如何将其传输到python。

有没有可用的参考资料，可以帮助我设置此选项或其他选项？

在Chrome上测试：版本79.0.3945.130（正式版本）（64位）

在Python中，您可以使用以下代码

    chrome_options = webdriver.ChromeOptions()
    experimentalFlags = ['same-site-by-default-cookies@1','cookies-without-same-site-must-be-secure@1']
    chromeLocalStatePrefs = { 'browser.enabled_labs_experiments' : experimentalFlags}
    chrome_options.add_experimental_option('localState',chromeLocalStatePrefs)
    driver = webdriver.Chrome(options=chrome_options)
    driver.get("https://www.bing.com")

Python Selenium客户端将发送以下功能

            }
         },
         "platformName": "any"
      },

         }
      },
      "platform": "ANY",
      "version": ""
   }
}

检查它是否实际工作。转到chrome：// flags /
