codes:

• server: https://github.com/authlib/example-oauth2-server
• client: https://docs.authlib.org/en/latest/client/flask.html

quick start:

1. init database

Create database test by yourself on MySQL, then run:

$ cd server
$ flask initdb

Check the test database and you will find four tables have been created.

+----------------+
| Tables_in_test |
+----------------+
| oauth2_client  |
| oauth2_code    |
| oauth2_token   |
| user           |
+----------------+

2. run oauth server

$ cd server
$ flask run

or you can run

python app.py

3. create user and client

access the server website: http://127.0.0.1:5000

input a name and press the "Login/Signup" button

click the "Create Client" and input like this

after submit you would get the client_id and client_secret

4. run client

Open the client/app.py and fill the client_id and client_secert

and run client with

$ python app.py

5. try the oauth2.0

access the client website: http://127.0.0.1:3000

click login.

because we have logged in the server, it knows our username.

check Consent and submit. tada, oauth2 success~

That's all for oauth2 login. But if you click Logout, it would call the server/logout. And if you want to login with oauth2, you should login the server first.
