[![Gem Version](https://badge.fury.io/rb/omniauth-google-oauth2.svg)](https://badge.fury.io/rb/omniauth-google-oauth2)
[![Build Status](https://travis-ci.org/zquestz/omniauth-google-oauth2.svg)](https://travis-ci.org/zquestz/omniauth-google-oauth2)
# OmniAuth Google OAuth2 Strategy
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
## Installation
Add to your `Gemfile`:
```ruby
gem 'omniauth-google-oauth2'
```
Then `bundle install`.
## Google API Setup
* Go to 'https://console.developers.google.com'
* Select your project.
* Go to Credentials, then select the "OAuth consent screen" tab on top, and provide an 'EMAIL ADDRESS' and a 'PRODUCT NAME'
* Wait 10 minutes for changes to take effect.
## Usage
Here's an example for adding the middleware to a Rails app in `config/initializers/omniauth.rb`:
```ruby
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET']
end
```
You can now access the OmniAuth Google OAuth2 URL: `/auth/google_oauth2`
For more examples please check out `examples/omni_auth.rb`
NOTE: While developing your application, if you change the scope in the initializer you will need to restart your app server. Remember that either the 'email' or 'profile' scope is required!
## Configuration
You can configure several options, which you pass in to the `provider` method via a hash:
* `scope`: A comma-separated list of permissions you want to request from the user. See the [Google OAuth 2.0 Playground](https://developers.google.com/oauthplayground/) for a full list of available permissions. Caveats:
* The `email` and `profile` scopes are used by default. By defining your own `scope`, you override these defaults, but Google requires at least one of `email` or `profile`, so make sure to add at least one of them to your scope!
* Scopes starting with `https://www.googleapis.com/auth/` do not need that prefix specified. So while you can use the smaller scope `books` since that permission starts with the mentioned prefix, you should use the full scope URL `https://docs.google.com/feeds/` to access a user's docs, for example.
* `redirect_uri`: Override the redirect_uri used by the gem.
* `prompt`: A space-delimited list of string values that determines whether the user is re-prompted for authentication and/or consent. Possible values are:
* `none`: No authentication or consent pages will be displayed; it will return an error if the user is not already authenticated and has not pre-configured consent for the requested scopes. This can be used as a method to check for existing authentication and/or consent.
* `consent`: The user will always be prompted for consent, even if he has previously allowed access a given set of scopes.
* `select_account`: The user will always be prompted to select a user account. This allows a user who has multiple current account sessions to select one amongst them.
If no value is specified, the user only sees the authentication page if he is not logged in and only sees the consent page the first time he authorizes a given set of scopes.
* `image_aspect_ratio`: The shape of the user's profile picture. Possible values are:
* `original`: Picture maintains its original aspect ratio.
* `square`: Picture presents equal width and height.
Defaults to `original`.
* `image_size`: The size of the user's profile picture. The image returned will have width equal to the given value and variable height, according to the `image_aspect_ratio` chosen. Additionally, a picture with specific width and height can be requested by setting this option to a hash with `width` and `height` as keys. If only `width` or `height` is specified, a picture whose width or height is closest to the requested size and requested aspect ratio will be returned. Defaults to the original width and height of the picture.
* `name`: The name of the strategy. The default name is `google_oauth2` but it can be changed to any value, for example `google`. The OmniAuth URL will thus change to `/auth/google` and the `provider` key in the auth hash will then return `google`.
* `access_type`: Defaults to `offline`, so a refresh token is sent to be used when the user is not present at the browser. Can be set to `online`. More about [offline access](https://developers.google.com/identity/protocols/OAuth2WebServer#offline)
* `hd`: (Optional) Limit sign-in to a particular Google Apps hosted domain. This can be simply string `'domain.com'` or an array `%w(domain.com domain.co)`. More information at: https://developers.google.com/accounts/docs/OpenIDConnect#hd-param
* `jwt_leeway`: Number of seconds passed to the JWT library as leeway. Defaults to 60 seconds.
* `skip_jwt`: Skip JWT processing. This is for users who are seeing JWT decoding errors with the `iat` field. Always try adjusting the leeway before disabling JWT processing.
* `login_hint`: When your app knows which user it is trying to authenticate, it can provide this parameter as a hint to the authentication server. Passing this hint suppresses the account chooser and either pre-fill the email box on the sign-in form, or select the proper session (if the user is using multiple sign-in), which can help you avoid problems that occur if your app logs in the wrong user account. The value can be either an email address or the sub string, which is equivalent to the user's Google+ ID.
* `include_granted_scopes`: If this is provided with the value true, and the authorization request is granted, the authorization will include any previous authorizations granted to this user/application combination for other scopes. See Google's [Incremental Authorization](https://developers.google.com/accounts/docs/OAuth2WebServer#incrementalAuth) for additional details.
* `openid_realm`: Set the OpenID realm value, to allow upgrading from OpenID based authentication to OAuth 2 based authentication. When this is set correctly an `openid_id` value will be set in `[:extra][:id_info]` in the authentication hash with the value of the user's OpenID ID URL.
Here's an example of a possible configuration where the strategy name is changed, the user is asked for extra permissions, the user is always prompted to select his account when logging in and the user's profile picture is returned as a thumbnail:
```ruby
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET'],
{
scope: 'userinfo.email, userinfo.profile, 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']`:
```ruby
{
"provider" => "google_oauth2",
"uid" => "100000000000000000000",
"info" => {
"name" => "John Smith",
"email" => "john@example.com",
"first_name" => "John",
"last_name" => "Smith",
"image" => "https://lh4.googleusercontent.com/photo.jpg",
"urls" => {
"google" => "https://plus.google.com/+JohnSmith"
}
},
"credentials" => {
"token" => "TOKEN",
"refresh_token" => "REFRESH_TOKEN",
"expires_at" => 1496120719,
"expires" => true
},
"extra" => {
"id_token" => "ID_TOKEN",
"id_info" => {
"azp" => "APP_ID",
"aud" => "APP_ID",
"sub" => "100000000000000000000",
"email" => "john@example.com",
"email_verified" => true,
"at_hash" => "HK6E_P6Dh8Y93mRNtsDB1Q",
"iss" => "accounts.google.com",
"iat" => 1496117119,
"exp" => 1496120719
},
"raw_info" => {
"sub" => "100000000000000000000",
"name" => "John Smith",
"given_name" => "John",
"family_name" => "Smith",
"profile" => "https://plus.google.com/+JohnSmith",
"picture" => "https://lh4.googleusercontent.com/photo.jpg?sz=50",
"email" => "john@example.com",
"email_verified" => "true",
"locale" => "en",
"hd" => "company.com"
}
}
}
```
### Devise
First define your application id and secret in `config/initializers/devise.rb`. Do not use the snippet mentioned in the [Usage](https://github.com/zquestz/omniauth-google-oauth2#usage) section.
Configuration options can be passed as the last parameter here as key/value pairs.
```ruby
config.omniauth :google_oauth2, 'GOOGLE_CLIENT_ID', 'GOOGLE_CLIENT_SECRET', {}
```
NOTE: If you are using this gem with devise with above snippet in `config/initializers/devise.rb` then do not create `config/initializers/omniauth.rb` which will conflict with devise configurations.
Then add the following to 'config/routes.rb' so the callback routes are defined.
```ruby
devise_for :users, controllers: { omniauth_callbacks: 'users/omniauth_callbacks' }
```
Make sure your model is omniauthable. Generally this is "/app/models/user.rb"
```ruby
devise :omniauthable, omniauth_providers: [:google_oauth2]
```
Then make sure your callbacks controller is setup.
```ruby
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def google_oauth2
# You need to implement the method below in your model (e.g. app/models/user.rb)
@user = User.from_omniauth(request.env['omniauth.auth'])
if @user.persisted?
flash[:notice] = I18n.t 'devise.omniauth_callbacks.success', kind: 'Google'
sign_in_and_redirect @user, event: :authentication
else
session['devise.google_data'] = request.env['omniauth.auth'].except(:extra) # Removing extra as it can overflow some session stores
redirect_to new_user_registration_url, alert: @user.errors.full_messages.join("\n")
end
end
end
```
and bind to or create the user
```ruby
def self.from_omniauth(access_token)
data = access_token.info
user = User.where(email: data['email']).first
# Uncomment the section below if you want users to be created if they don't exist
# unless user
# user = User.create(name: data['name'],
# email: data['email'],
# password: Devise.friendly_token[0,20]
# )
# end
user
end
```
For your views you can login using:
```erb
<%= link_to "Sign in with Google", user_google_oauth2_omniauth_authorize_path %>
<%# Devise prior 4.1.0: %>
<%= link_to "Sign in with Google", user_omniauth_authorize_path(:google_oauth2) %>
```
An overview is available at https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview
### One-time Code Flow (Hybrid Authentication)
Google describes the One-time Code Flow [here](https://developers.google.com/+/web/signin/server-side-flow). This hybrid authentication flow has significant functional and security advantages over a pure server-side or pure client-side flow. The following steps occur in this flow:
1. The client (web browser) authenticates the user directly via Google's JS API. During this process assorted modals may be rendered by Google.
2. On successful authentication, Google returns a one-time use code, which requires the Google client secret (which is only available server-side).
3. Using a AJAX request, the code is POSTed to the Omniauth Google OAuth2 callback.
4. The Omniauth Google OAuth2 gem will validate the code via a server-side request to Google. If the code is valid, then Google will return an access token and, if this is the first time this user is authenticating against this application, a refresh token. Both of these should be stored on the server. The response to the AJAX request indicates the success or failure of this process.
This flow is immune to replay attacks, and conveys no useful information to a man in the middle.
The omniauth-google-oauth2 gem supports this mode of operation out of the box. Implementors simply need to add the appropriate JavaScript to their web page, and they can take advantage of this flow. An example JavaScript snippet follows.
```javascript
// Basic hybrid auth example following the pattern at:
// https://developers.google.com/identity/sign-in/web/reference
<script src="https://apis.google.com/js/platform.js?onload=init" async defer></script>
...
function init() {
gapi.load('auth2', function() {
// Ready.
$('.google-login-button').click(function(e) {
e.preventDefault();
gapi.auth2.authorize({
client_id: 'YOUR_CLIENT_ID',
cookie_policy: 'single_host_origin',
scope: 'email profile',
response_type: 'code'
}, function(response) {
if (response && !response.error) {
// google authentication succeed, now post data to server.
jQuery.ajax({type: 'POST', url: '/auth/google_oauth2/callback', data: response,
success: function(data) {
// response from server
}
});
} else {
// google authentication failed
}
});
});
});
};
```
#### Note about mobile clients (iOS, Android)
The documentation at https://developers.google.com/identity/sign-in/ios/offline-access specifies the _REDIRECT_URI_ to be either a set value or an EMPTY string for mobile logins to work. Else, you will run into _redirect_uri_mismatch_ errors.
In that case, ensure to send an additional parameter `redirect_uri=` (empty string) to the `/auth/google_oauth2/callback` URL from your mobile device.
#### Note about CORS
If you're making POST requests to `/auth/google_oauth2/callback` from another domain, then you need to make sure `'X-Requested-With': 'XMLHttpRequest'` header is included with your request, otherwise your server might respond with `OAuth2::Error, : Invalid Value` error.
## Fixing Protocol Mismatch for `redirect_uri` in Rails
Just set the `full_host` in OmniAuth based on the Rails.env.
```
# config/initializers/omniauth.rb
OmniAuth.config.full_host = Rails.env.production? ? 'https://domain.com' : 'http://localhost:3000'
```
