This app is an example of an OAuth 2 provider using Doorkeeper gem, Rails 7.x and Devise. Check out the app hosted on heroku for a live demo.
For more information about the gem, documentation, wiki and another resources, check out the project on GitHub
First clone the repository from GitHub:
git clone git://github.com/doorkeeper-gem/doorkeeper-provider-app.git
Install all dependencies with:
bundle install
After that you're almost ready to go.
The configuration is quite simple, all you need to do is run:
bundle exec rake db:setup
This will generate all necessary tables, create fake data, create an user and a client application.
The generated user email is [email protected]
and password is doorkeeper
.
The application id
and secret
will show up on terminal when the script ends.
After that, you can just fire up the rails server
and you're ready to go.
The endpoints is mounted under /oauth
so our routes look like this:
GET /oauth/authorize
POST /oauth/authorize
DELETE /oauth/authorize
POST /oauth/token
resources /oauth/applications
This app provides a sample JSON API under /api/v1
. The current API endpoints are:
/api/v1/profiles.json
/api/v1/me.json
In routes.rb
you can check out how they're made:
namespace :api do
namespace :v1 do
resources :profiles
get '/me' => "credentials#me"
end
end
We namespace the API controllers to avoid name clashing and collisions between your existing application and the API. This way, you can make changes to your application without messing up with the API's behavior.
You can find all controllers under /app/controllers/api/v1
folder.
The api_controller.rb
works as a parent class to the other controllers. It only defines a method that returns
the current resource owner, based on the access token:
def current_resource_owner
User.find(doorkeeper_token.resource_owner_id) if doorkeeper_token
end
This is required if you want to return data based on the current user, like in credentials_controller.rb
To make your API only available for OAuth users, you need to tell doorkeeper to require an access token in your api controller, like this:
module Api::V1
class ProfilesController < ApiController
before_action :doorkeeper_authorize!
def index
render json: Profile.recent
end
end
end
However, see also the Doorkeeper wiki article about using scopes.
If you attempt to access any of the protected resources without an proper access token, you'll get an 401 Unauthorized
response.
You can manage all client applications in /oauth/applications
.
If you want to create a client application, check out this example using Sinatra and this another one using Rails and Devise.
