python - How to determine if the crawler has logged in successfully?

Question

Read this tutorial: https://github.com/xchaoinfo/fuck-login/blob/master/015 CSDN/csdn.py, this is the code to simulate logging into csdn, using response.status_code (the above link code (line 63) is equal to 200 to determine whether the login is successful, but this is not the case. I tried to enter the wrong password, and the status_code is still equal to 200. I looked online and said that status_code==200 means that the server successfully accepted the client. ask.

So what should we do to determine whether the login is successful?
