This is an example of OpenID Connect 1.0 server in Flask and Authlib.

• Documentation: https://docs.authlib.org/en/latest/flask/2/
• Authlib Repo: https://github.com/lepture/authlib

Take a quick look

This is a ready to run example, let's take a quick experience at first. To run the example, we need to install all the dependencies:

$ pip install -r requirements.txt

Set Flask and Authlib environment variables:

# disable check https (DO NOT SET THIS IN PRODUCTION)
$ export AUTHLIB_INSECURE_TRANSPORT=1

Create Database and run the development server:

$ flask initdb
$ flask run

Now, you can open your browser with http://127.0.0.1:5000/, login with any name you want.

Before testing, we need to create a client:

NOTE: YOU MUST ADD openid SCOPE IN YOUR CLIENT

Let's take authorization_code grant type as an example. Visit:

http://127.0.0.1:5000/oauth/authorize?client_id=${CLIENT_ID}&scope=openid+profile&response_type=code&nonce=abc

After that, you will be redirect to a URL. For instance:

https://example.com/?code=RSv6j745Ri0DhBSvi2RQu5JKpIVvLm8SFd5ObjOZZSijohe0

Copy the code value, use curl to get the access token:

curl -u "${CLIENT_ID}:${CLIENT_SECRET}" -XPOST http://127.0.0.1:5000/oauth/token -F grant_type=authorization_code -F code=RSv6j745Ri0DhBSvi2RQu5JKpIVvLm8SFd5ObjOZZSijohe0
