OAuth flow

Authorization code flow:

http://localhost:7777/oauth/authorize?client_id=client-id&state=123456&response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A7000%2Fcallback&state=dvoQ6Jtv0PV68tBUgUMM035oFiZw57

Implicit flow: http://localhost:7777/oauth/authorize?client_id=client-id&state=123456&response_type=token&redirect_uri=http%3A%2F%2Flocalhost%3A7000%2Fcallback&state=dvoQ6Jtv0PV68tBUgUMM035oFiZw57

Exchange the code to get the token with {code} replaced by the code obtained in previous step.

http -f -a client-id:client-secret http://localhost:7777/oauth/token grant_type=authorization_code code={code}

Get user info:

http http://localhost:7777/oauth/user_info 'Authorization:Bearer {token}'

How to create new migration

Whenever the model changes, a new migration needs to be created

Set the database connection to use staging environment:

ln -sf ~/config/simplelogin/staging.env .env

Generate the migration script and make sure to review it:

flask db migrate

Code structure

OpenID, OAuth2 response_type & scope

According to https://medium.com/@darutk/diagrams-of-all-the-openid-connect-flows-6968e3990660

• response_type can be either code, token, id_token or any combination.
• scope can contain openid or not

Below is the different combinations that are taken into account until now:

response_type=code scope: with openid in scope, return id_token at /token: OK without: OK

response_type=token scope: with and without openid, nothing to do: OK

response_type=id_token return id_token in /authorization endpoint

response_type=id_token token return id_token in addition to access_token in /authorization endpoint

response_type=id_token code return id_token in addition to authorization_code in /authorization endpoint
