OAuth2 API Guard Sample

This Rails app demos how to build an OAuth 2 Authorization Server and Resource Server (API), and guard it with OAuth 2 Bearer Token.

Most components are built with existing solutions:

  • Resource Owner (User) & its Authentication: Devise
  • Authorization Server: Doorkeeper
  • Resource Server (API): Grape
  • Resource Server Guard: Rack::OAuth2 (built from scratch, not using doorkeeper_for which is Rails-only)

Tutorials

I've written the tutorial of this sample in my blog, however it's currently written only in Chinese. I'm going to publish an English version soon.
