Detailed explanation of a simple example of developing UnionPay payment interface in PHP

Payment interface Now there are third-party payment interfaces and bank payment interfaces. Here we will introduce the method of developing the PHP version of UnionPay payment interface.

When paying with UnionPay, you must first pay attention to two important parts:

The extension openssl is enabled

The examples in the development manual are only for reference, because they are basically wrong. You can try to go to the official website for a demo. . . Note that now UnionPay is developing, there is no test key provided, it can only be developed in the official environment

The following is a payment class I wrote using ThinkPHP
