Pro-test repair payment gateway early check-in source code/with tutorial/payment received/optimize code scanning process

Friends shared that H5 gets up early to check in, so I won't introduce the specific model. Everyone should have an impression of this model. This model has been released before. After completing this model, the platform's gateway address was changed. The day before yesterday, a member friend who downloaded and built it reflected this problem, but explained it to him did not make sense. While updating the gateway address, I also optimized the code scanning process, so that all callbacks and logins will be OK. The tutorial is the same as before, and it will be OK as soon as you build it. Everything has been repaired, so be careful and make no mistakes. The things are as shown below. Take them if you need them ~ The tutorial has also been updated.
The new H5 early check-in tutorial has been packaged together.
