How to solve the 302 redirection problem when using requests in Python

When using requests to simulate login, using request.get(url) directly can easily cause 302 redirection. The reason is that cookies are not persistent (requests comes with cookie processing, but it is not persistent).

The solution is to use the request.Session() object to persist cookie and other states.

For example:

 s = requests.Session()
 response = s.get(url, headers=headers)
 
 #其他操作

Another situation that will cause 302 redirection is: when using the Session object to request the page, the corresponding request header (for example: Referer) is not passed in, causing the server verification to fail. Return

redirect message. The solution is to construct the corresponding request header and pass it in when fetching the page.
