This article mainly introduces the development process of PHP WeChat payment in detail. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.
Put the Cert and Lib directories of the WeChat payment SDK Thinkphp, the directory is
Now we will introduce the WeChat payment authorization directory issue. The first is to fill in the payment authorization directory in the WeChat payment development configuration,
Then fill in the js interface security domain.
After these settings are completed, it is basically half completed. Pay attention to the set directory and the directory in my thinkphp.
Fill in the relevant configuration correctly.
