Python Simulation Login

Here's a simulated login for Python (www.zhihu.com) to test

First use Firefox and fiddler to intercept all requests, including the URL to the landing page (www.zhihu.com/signin) and the login URL (www.zhihu.com/login/phone_num)

To view the source code of the page, you need to pass in a special value: __XSRF=1A2823B23E14B52E9F4867CB5D60D3D3

This special property is in the request to access the login page, back from the server side, nonsense said, on the code
