This is the callback directory
This is the code
Jump to the home page after successful payment. Then the callback does not respond. Is it a problem with my jump?
....After going through 10,000 pitfalls, I am about to succeed. Something went wrong with the callback. . Don't know where it is yet. God, please give me a clear path.
If the callback responds, a certain data in the database will be updated. But after the payment was successful, there was no callback and the database did not respond. God, please show me a clear way. God, please show me a clear way. God, please show me a clear way. Important things must be said three times!

The callback function in the second picture cannot be sure of success. It depends on the asynchronous notification url you set in the first picture. After the user pays, WeChat will access the asynchronous notification url you set and send some information back to this page. Parameters, if it doesn’t work, it’s because your URL setting is wrong, or there’s a bug in the callback page. Isn’t there a debugging tool? It’s OK to monitor the callback page
