LZ did not understand the meaning of the existence of the verification code ah, if you can skip the verification code, the verification code has the meaning of existence? The verification code is to prevent the robot and other simulated human operation and exist. Of course, there are some online verification code identification tools, but are only able to identify some of the image is relatively clear and simple verification code. Complex verification codes still have to be manually manipulated.

1. Simple verification code is submitted after OCR recognition
2. Complex verification code, then only after the manual recognition after the download submitted.

I have previously written a mock login with a verification code. Ideas are as follows:
1. Load the verification code required to login and record the cookies
2, the verification code, user name, password, cookies submitted to the landing page
3. Successful landing.
This is a manual identification verification code.
If the machine is to be recognized, it will be helpless.
