Omniauth::HubAz

An omniauth gem to authenticate with hub-az

Add this line to your application's Gemfile:

gem 'omniauth-hub_az'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install omniauth-hub_az

Create an initializer file and configure the following parameters;

Omniauth::HubAz.setup do |config|
  config.public_key = OpenSSL::PKey::RSA.new(Rails.application.credentials.hub_az[:public_key])
  config.algorithm = 'RS512'
end

Configure the devise.rb initializer;

  config.omniauth :hub_az, Rails.application.credentials.hub_az[:client_id], Rails.application.credentials.hub_az[:client_secret]

Change your routes file to handle omniauth authentication;

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

and create that controller

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController

  def hub_az
    authorization = request.env["omniauth.auth"]

    # test that the info is valid? (verification with the public key was successfull)
    if authorization.info.valid? && authorization.info.roles.include?('some-role')
      @user = User.find_or_initialize_by(email: authorization.info.email) do |user|
        user.password = Devise.friendly_token[0, 20]
      end
      # set additional attributes that should be updated after each authentication
      @user.save!

      sign_in_and_redirect @user, event: :authentication
    else
      redirect_to new_user_session_path, alert: 'Unable to login, make sure you have the correct roles assigned.'
    end
  end

end

Include the mixin to your API controller to obtain additional methods to valid an incoming Bearer token;

class Api::V1::ExampleController < ApplicationController

  include Omniauth::HubAz::Mixins::ControllerHelper

  before_action :valid_hub_az_token_required!
  before_action do
    hub_az_token_requires_role!('some-api-role')
  end

end
