PHP WeChat payment development example, PHP payment example

PHP WeChat payment development process is shared with everyone for your reference. The specific content is as follows

1. Development environment
Thinkphp 3.2.3
WeChat: Service account, certified
Development domain name: http://test.paywechat.com (customized domain name, not accessible from the external network)

2. Relevant files and permissions are required
WeChat payment needs to be activated
WeChat public platform developer documentation: http://mp.weixin.qq.com/wiki/home/index.html
WeChat Pay developer documentation: https://pay.weixin.qq.com/wiki/doc/api/index.html
WeChat payment SDK download address: https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

3. Development
Download the PHP version of WeChat Payment SDK. The file directory is as shown below:

Put the Cert and Lib directories of WeChat Payment SDK into Thinkphp, the directory is

Now we will introduce the issue of WeChat payment authorization directory. The first step is to fill in the payment authorization directory in WeChat payment development configuration.

Then fill in the JS interface security domain.

Finally set web authorization

After these settings are completed, it is almost half complete. Pay attention to the set directory and the directory in my thinkphp.

4. WeChat payment configuration

Fill in the relevant configuration correctly.

This is basically complete, you can open it on WeChat http://test.paywechat.com/Charge/index.php/Test/index/
In my environment, the HTTP server does not rewrite the URL. WeChat payment continues to be explored. There may be problems or deficiencies in some places. I hope everyone can understand and learn from each other.

The above is all the content of PHP WeChat payment development. I hope it will be helpful to everyone's learning, and I also hope everyone will support Bangkejia.
