When doing the login authorization of the mini program today, after login authorization, When skey was brought into the background and the session value of skey was obtained, it could not be obtained. After struggling for a long time, I realized that it was a problem with session_id. It is because the session_id is not passed that the backend receives the value passed from the frontend. The value is clearly present in the session but cannot be obtained.

When logging in for authorization, the background server must return the session_id of this session

The applet must save the session_id passed from the background

When users log in to the mini program, they must first determine whether the current user is authorized. The skey needs to be passed into the background to determine whether the current skey has expired. When requesting the background, you need to add session_id to the hearer header to determine whether it belongs to the same session.
