Python Simulation Login 3: Enter the course selection system (manually enter the verification code stage)

In fact, the most want to do is to choose the class plug-in, so this time to try to choose the course system, but the course selection system has a verification code.　It's a sore egg.　needs to be identified. But now you can use another method. is to download to local manual input. It only takes one time to be enough.　Because the landing is successful, you can manipulate other things at will. Later, the intelligent identification of verification code is learned.

The first is primarily analog logic. First set up a cookie memory, use it to access the verification Code link. Then you get a cookie. There is also a download good captcha image, on the local. Then submit the verification Code, username, password, and the cookie to the login.　So the cookie is consistent. A bit uncomfortable is the need to see what the image looks like in the local, and then enter the console. The specific code is:
