如何通过Python请求复制Google登录？

Question

众所周知，谷歌使用电子邮件和密码向其服务器验证帐户。我如何做他们登录网站（https://accounts.google.com/signin/v2/identifier?sacu=1&rip=1&flowName=GlifWebSignIn&flowEntry=ServiceLogin）上的Auth所做的相同操作；通过Python请求？我检查了一下，在网络请求中出现了很多东西，比如f.req，值出现在no-where和类似的地方。下面的请求是发送实际登录请求所必需的，该请求通过向其服务器发送电子邮件字符串来声明是否在google数据库中找到了该帐户，然后它会收到gf.alr | gf.uicd | gf.ttu，其值都是实际登录请求所必需的。有人能帮我理解什么是f.req和bgRequest吗？我从哪里可以得到这些？我设法很容易地得到了主机的cookies&；但是我不完全理解为什么NID的价值不断变化。如果有人能帮助我，我会很高兴的
