omniauth-gitbook

Gitbook Oauth2 strategy for Omniauth.

Usage - OmniAuth

If you only integrate OmniAuth to your project, follows to OmniAuth offical document, you have to add callback route and have a controller to handle data from oauth exchange.

Before all, add configuration for omniauth-gotbook at config/initializers/omniauth.rb.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :developer unless Rails.env.production?
  provider :gitbook, ENV['CLIENT_ID'], ENV['CLIENT_SECRET']
end

Add callback route to route.rb.

get '/auth/:provider/callback', to: 'sessions#create'

Handle json data in controller.

class SessionsController < ApplicationController
  def create
    @user = User.find_or_create_from_auth_hash(auth_hash)
    self.current_user = @user
    redirect_to '/'
  end

  protected

  def auth_hash
    request.env['omniauth.auth']
  end
end

Usage - Devise

If you integrate Devise to your rails project, follows to Devise - OmniAuth: Overview, here are some steps.

If you have no config/initializers/devise.rb, run the generator.

rails g devise:install

Add configuration to config/initializers/devise.rb for omniauth-gitbook.

Devise.setup do |config|
  config.omniauth :gitbook, [CLIENT_ID], [CLIENT_SECRET]
end

And if your devise model named User, add callback route to route.rb.

devise_for :users, controllers: { omniauth_callbacks: 'users/omniauth_callbacks' }

Then you can get user's data in controller.

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def gitbook
    @user = User.find_or_create_by_oauth2(request.env[omniauth.auth])
    
    if @user.persisted?
      sign_in_and_redirect_to root_path, event: :authentication
    end
  end
end
