Omniauth::Bungie::Oauth2

A Bungie OAuth2 strategy for Omniauth.

Add this line to your application's Gemfile:

gem 'omniauth-bungie-oauth2'

And then execute:

$ bundle

For usage this gem You must create an application with authentication access on Bungie.net. You should set Confidential value in the OAuth Client Type field.

After this, you can integrate this strategy with your application. (More about A Bungie OAuth2 you can read on Help page)

This provider uses four arguments:

• client_id - OAuth client_id,
• client_secret - OAuth client_secret,
• x_api_key - API Key,
• redirect_uri - Redirect URL.

For integration with Rails You have to setup your strategy configuration in config/initializers/devise.rb:

Devise.setup do |config|
  config.omniauth :bungie,
    'client_id',
    'client_secret',
    'x_api_key',
    'redirect_url'
end

You can also define it in initializers with config.middleware.use OmniAuth::Builder.

After this You should define omniauth callback in routes and controller.

routes.rb:

devise_for :users, :controllers => {
  :omniauth_callbacks => 'devise/omniauth_callbacks',
}

devise/omniauth_callbacks_controller.rb

class Devise::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def bungie
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      @user.remember_me = true

      sign_in_and_redirect @user, :event => :authentication

      set_flash_message(:notice, :success, :kind => 'Bungie') if is_navigational_format?
    else
      session["devise.bungie_data"] = request.env["omniauth.auth"]

      redirect_to '/'
    end
  end
end

Now You should define from_omniauth method in your User model:

def self.from_omniauth(auth)
  where(:uid => auth.uid).first_or_create do |user|
    user.membership_id = auth.info.membership_id
    user.display_name  = auth.info.display_name
    user.unique_name   = auth.info.unique_name
  end
end

Do not forget to specify model fields in your migration.

After all manipulation the request.env["omniauth.auth"] have the next fields:

• uid with BungieNetUser membershipId
• info with membershipId, uniqueName, displayName
• extra with GetMembershipDataForCurrentUser result
