php Example third party

The following editor will bring you a WeChat third-party login (native) demo [must read]. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

I have been working in an ecstore company for a while. The company hopes to develop its own products and has been cultivating new people.

Recently I have to log in to WeChat myself. I wrote the native WeChat third-party login based on the ectore framework to get familiar with WeChat third-party login and write it on ecstore.

A simple demo, not very good, I want to share it with you, hoping it can bring ideas to friends who want to do third-party login on WeChat...
