Cgtrader OAuth2 Strategy for OmniAuth.

Add to your Gemfile:

gem 'omniauth-cgtrader'

Then bundle install.

OmniAuth::Strategies::Cgtrader is simply a Rack middleware. Read the OmniAuth docs for detailed instructions: https://github.com/intridea/omniauth.

Here's a quick example, adding the middleware to a Rails app in config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :cgtrader, ENV['CGT_API_ID'], ENV['CGT_API_SECRET']
end

Here's an example Auth Hash available in request.env['omniauth.auth']:

{
  provider: 'cgtrader',
  uid: '1234567',
  info: {
    id: '123',
    email: 'joe@bloggs.com',
    username: 'joe_bloggs',
    is_admin: false,
    avatar_url: 'https://upload.wikimedia.org/wikipedia/commons/8/89/Portrait_Placeholder.png'
  },
}
