Flask OAuth2 Server

I am creating a REST API using Swagger based on the PetStore example.

I am using the Python-Flask Generated Server.

I need to use OAuth2 for authentication.

 

From what I undeerstand I need to:

1. Implement a user database.

2. Log in with a registered user and return an Access Token.

3. Use this token with any subsequent API calls to access resources.

 

I see examples where one uses e.g. FaceBook or Google to obtain the AccessToken but I want my server to handle everything.

 

Are there any examples of a python OAuth2 Server that works with Swagger?

When I test the online PetStore Editor: https://editor.swagger.io it directs me to this link:

http://petstore.swagger.io/oauth/login.jsp which says: "You can find the source code to the server" but the link is broken :(
