Provides various official and user-released code examples. For code reference, you are welcome to exchange and learn the verification code I hate 3.2.2. Unlock the current form in the same unlock mode as your mobile phone to prevent machine registration.
I can't paste it. I will give it an address. It's from open source China.

I didn't understand the dumb, so it was just a mess. Here I will explain the application scenario of this front-end.
My design is to use the current empty module to receive and verify
1. Use the initial function in the Controller to generate a 32-bit password based on the current browser, message, and other information. (judge before generation, if the browser is not used or the message is incomplete, it will be used when the form is submitted ,)
2. Fill in the form POST address of the client (if it is not unlocked, the POST target address does not exist, and the 404 page is displayed directly ),
3. The operation between unlocking has been said, and you can do whatever you want. I added a get here, and the specific information is as follows, the server uses the current time and other information to decrypt the 32-bit encryption matrix, and finally obtains the 32-bit hexadecimal address, after the submission, the post value will change accordingly to the 32-bit hex address generated at the end. After the server compares the value, it must be processed or discarded.
