This article mainly introduces the "how to use python code to achieve Mini Program login process timing" related knowledge, editor through the actual case to show you the operation process, the method of operation is simple and fast, practical, I hope that this "how to use python code to achieve Mini Program login process timing" article can help you solve the problem.

Login on Mini Program

Login process timing

Description:

Call wx.login () to get the temporary login credential code and pass it back to the developer server.

Call the auth.code2Session API in exchange for the user's unique ID OpenID and session key session_key.

After that, the developer server can generate a custom login state according to the user identity, which can be used to identify the user during the front-end interaction in the subsequent business logic.

Note:

The session key session_key is a key that encrypts and signs user data. In order to apply its own data security, the developer server should not send the session key to Mini Program, nor should it provide this key to the public.

Temporary login credentials code can only be used once

Login summary of Mini Program

1. Execute wx.login () on Mini Program to obtain code

2 send the code in 1 to the backend, and the backend calls the interface auth.code2Session to get openid and session_key

3 Custom login status, we generate a key to bind with openid and session_key. Return key to Mini Program

4 save it on Mini Program, and the next time you request an API to log in, bring key with you.
