python-3.x - 如何在 python selenium 中设置 Chrome 实验性选项 same-site-by-default-cookie

Question

我想这应该可行:

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

为 future 的 chrome 版本启用 samesite cookies 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 手动更改选项并查看它是否正常工作。但是我想自动化它并运行测试脚本来查看它。

这里有java代码:https://groups.google.com/forum/#!topic/chromedriver-users/cI8hj7eihRo 这可以做到，但我不确定如何将它转移到 python。

是否有任何引用资料可以帮助我设置此选项或不同的选项？

在 Chrome 上测试:版本 79.0.3945.130(官方构建)(64 位)

在Python中你可以使用下面的代码

    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 客户端将发送如下功能

      },

}

检查它是否真的有效。转到 chrome://flags/
