ThinkPHP WeChat code scanning payment interface

Recently I have been struggling with WeChat scan code payment. I read the official WeChat documentation and searched many web pages. I found that it does not match the documentation/demo. Now I have figured it out myself (the file name has been changed). I will post it and share it.

1. Place useful official lib files and related files in the vendor

2. Call the same payment interface

WechatController

The above introduces the ThinkPHP WeChat QR code scanning payment interface, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
