This is called DarkWatchman. It cannot take a course automatically now, but it can trigger one link to send email to you, so you can be notified to go to take a course you want.
1. Server side is used to receive information. I use PHP to send email. You may want to change it if you like.
2. Client side is used to auto refresh page in Chrome. Please use your own server side link.
3. If you have a useable service to recognize identifying code, I think you can improve DarkWatchman to take course automatically. Go ahead! Students will thank you.
Let us study more useful things and take less time to select courses!
