oauth2-provider

Simple OAuth2 provider code extracted from hashblue.com

Details

• Implements draft 11 of the oauth2 spec
• Handles the authorization_code and password grant types
• Supports ActiveRecord and Mongoid

Usage Instructions

In your Gemfile:

gem 'oauth2-provider', :git => 'git@github.com:freerange/oauth2-provider.git'

If you're using ActiveRecord, grab the schema out of spec/schema.rb, and run the migration.

To dish out authorization codes you will need to implement something like this:

class AuthorizationController < ApplicationController
  include OAuth2::Provider::Rack::AuthorizationCodesSupport

  before_filter :authenticate_user!
  before_filter :block_invalid_authorization_code_requests

  def new
    @client = oauth2_authorization_request.client
  end

  def create
    if params[:yes].present?
      grant_authorization_code(current_user)
    else
      deny_authorization_code
    end
  end

end

And add a couple of routes:

match "/oauth/authorize", :via => :get, :to => "authorization#new"
match "/oauth/authorize", :via => :post, :to => "authorization#create"

oauth2-provider will handle requests to /oauth/access_token to handle conversion of authorization codes to access tokens.
