WeChat applet session cannot be cached

Question

1, the front end has put the session_id in the header.

2. The problem now is that the session_id of the server will change. Every time I call my backend interface, the session_id changes, and the session still cannot be saved. How to solve this.

Answer 1

It is equivalent to a new connection access interface every time, and it is useless to save the session.

Answer 2

This should be caused by cross-domain issues
