Debugging can be performed by writing files or databases. I usually write files! For example, the code entry begins to write files, record the user's openid and sent content, and so on. The most extreme case is that each line of code is followed by debugging information. of course, this is not necessary! You just need to add it where you are interested and have questions! If the previous debugging information is available and the other debugging information is missing, it must be a problem with the intermediate code! In addition, remember to check whether the code has syntax errors or the like. open it in the editor.

Another php example in the public account development document first runs the example. Then, compare the example to debug your code at, and ensure that you have no problem with the connection.
Then, I made a client to simulate the user to send messages to the background and test my logic.
