Introducción

The

gem omniauth-google-oauth2 provides a strategy to authenticate with Google via OAuth2 in OmniAuth.

Get your API key at:

https://code.google.com/apis/console/

Note the Client ID and the Client Secret.

For more details, read the Google docs:

https://developers.google.com/accounts/docs/OAuth2.

Configuration

You can configure several options, which you pass in to the provider method via a hash:

Here's an example of a possible configuration where

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"],
    {
      :name => "google",
      :scope => "userinfo.email, userinfo.profile, plus.me, http://gdata.youtube.com",
      :prompt => "select_account",
      :image_aspect_ratio => "square",
      :image_size => 50
    }
end

Auth Hash

Here's an example of an authentication hash available in the callback by accessing request.env["omniauth.auth"]:

{
    :provider => "google_oauth2",
    :uid => "123456789",
    :info => {
        :name => "John Doe",
        :email => "john@company_name.com",
        :first_name => "John",
        :last_name => "Doe",
        :image => "https://lh3.googleusercontent.com/url/photo.jpg"
    },
    :credentials => {
        :token => "token",
        :refresh_token => "another_token",
        :expires_at => 1354920555,
        :expires => true
    },
    :extra => {
        :raw_info => {
            :id => "123456789",
            :email => "user@domain.example.com",
            :verified_email => true,
            :name => "John Doe",
            :given_name => "John",
            :family_name => "Doe",
            :link => "https://plus.google.com/123456789",
            :picture => "https://lh3.googleusercontent.com/url/photo.jpg",
            :gender => "male",
            :birthday => "0000-06-25",
            :locale => "en",
            :hd => "company_name.com"
        }
    }
}
