About TP5-WeChat H5 Payment

Directly upload the code to use the official DEMO

We directly have a method to pay:

There will be a few problems

1: Remember that money is a digital type

2: When returning to the jump link at the end: remember to add &redirect_url= address to the tail, otherwise it will not be lifted

3: For browsers like Baidu APP, there will be no callback after successful payment. The value can get the ID value, and use this to determine whether to pay.

4: You can go to WeChat to obtain information such as APPid of other merchants!
