How to identify Yi verification code?

Rookie, don't use it for improper purposes. I'll teach you.

The general idea is this: take out the picture of the verification code and put it in the photo frame (you can create a new window, do it yourself, add a button and the edit box will be OK). By setting a code to trigger this window, you can achieve the effect of manually entering the verification code. As for whether you understand or not, that's your responsibility. Don't use it on crooked ways.
