Want to know where the access_token of each system is stored? It stands to reason that this situation can be avoided by ensuring that each system reads the cache in one place!

Our general approach is to store it in redis. The premise is that the redis data read by your three systems is consistent!

Save to redis and call together.

The above is a WeChat public account shared by multiple systems. When uploading pictures, the access_token expired will be returned. How to solve it? For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
