Gem Version

Description

This is Google's officially supported ruby client library for using OAuth 2.0 authorization and authentication with Google APIs.

Install

Be sure https://rubygems.org/ is in your gem sources.

For normal client usage, this is sufficient:

$ gem install googleauth

Example Usage

require 'googleauth'

# Get the environment configured authorization
scopes =  ['https://www.googleapis.com/auth/cloud-platform',
           'https://www.googleapis.com/auth/compute']
authorization = Google::Auth.get_application_default(scopes)

# Add the the access token obtained using the authorization to a hash, e.g
# headers.
some_headers = {}
authorization.apply(some_headers)

Application Default Credentials

This library provides an implementation of application default credentials for Ruby.

The Application Default Credentials provide a simple way to get authorization credentials for use in calling Google APIs.

They are best suited for cases when the call needs to have the same identity and authorization level for the application independent of the user. This is the recommended approach to authorize calls to Cloud APIs, particularly when you're building an application that uses Google Compute Engine.

User Credentials

The library also provides support for requesting and storing user credentials (3-Legged OAuth2.) Two implementations are currently available, a generic authorizer useful for command line apps or custom integrations as well as a web variant tailored toward Rack-based applications.

The authorizers are intended for authorization use cases. For sign-on, see Google Identity Platform

Example (Web)

require 'googleauth'
require 'googleauth/web_user_authorizer'
require 'googleauth/stores/redis_token_store'
require 'redis'

client_id = Google::Auth::ClientId.from_file('/path/to/client_secrets.json')
scope = ['https://www.googleapis.com/auth/drive']
token_store = Google::Auth::Stores::RedisTokenStore.new(redis: Redis.new)
authorizer = Google::Auth::WebUserAuthorizer.new(
  client_id, scope, token_store, '/oauth2callback')


get('/authorize') do
  # NOTE: Assumes the user is already authenticated to the app
  user_id = request.session['user_id']
  credentials = authorizer.get_credentials(user_id, request)
  if credentials.nil?
    redirect authorizer.get_authorization_url(login_hint: user_id, request: request)
  end
  # Credentials are valid, can call APIs
  # ...
end

get('/oauth2callback') do
  target_url = Google::Auth::WebUserAuthorizer.handle_auth_callback_deferred(
    request)
  redirect target_url
end

Example (Command Line)

require 'googleauth'
require 'googleauth/stores/file_token_store'

OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'

scope = 'https://www.googleapis.com/auth/drive'
client_id = Google::Auth::ClientId.from_file('/path/to/client_secrets.json')
token_store = Google::Auth::Stores::FileTokenStore.new(
  :file => '/path/to/tokens.yaml')
authorizer = Google::Auth::UserAuthorizer.new(client_id, scope, token_store)

user_id = ENV['USER']
credentials = authorizer.get_credentials(user_id)
if credentials.nil?
  url = authorizer.get_authorization_url(base_url: OOB_URI )
  puts "Open #{url} in your browser and enter the resulting code:"
  code = gets
  credentials = authorizer.get_and_store_credentials_from_code(
    user_id: user_id, code: code, base_url: OOB_URI)
end

# OK to use credentials

Example (Service Account)

scope = 'https://www.googleapis.com/auth/androidpublisher'

authorizer = Google::Auth::ServiceAccountCredentials.make_creds(
  json_key_io: File.open('/path/to/service_account_json_key.json'),
  scope: scope)

authorizer.fetch_access_token!

You can also use a JSON keyfile by setting the GOOGLE_APPLICATION_CREDENTIALS environment variable.

export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_json_key.json
require 'googleauth'
require 'google/apis/drive_v3'

Drive = ::Google::Apis::DriveV3
drive = Drive::DriveService.new

scope = 'https://www.googleapis.com/auth/drive'

authorizer = Google::Auth::ServiceAccountCredentials.from_env(scope: scope)
drive.authorization = authorizer

list_files = drive.list_files()

3-Legged OAuth with a Service Account

This is similar to regular service account authorization (see this answer for more details on the differences), but you'll need to indicate which user your service account is impersonating by manually updating the sub field.

scope = 'https://www.googleapis.com/auth/androidpublisher'

authorizer = Google::Auth::ServiceAccountCredentials.make_creds(
  json_key_io: File.open('/path/to/service_account_json_key.json'),
  scope: scope
)
authorizer.update!(sub: "[email protected]")

authorizer.fetch_access_token!

Example (Environment Variables)

export GOOGLE_ACCOUNT_TYPE=service_account
export GOOGLE_CLIENT_ID=000000000000000000000
export [email protected]
export GOOGLE_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----\n...\n-----END PRIVATE KEY-----\n"
require 'googleauth'
require 'google/apis/drive_v3'

Drive = ::Google::Apis::DriveV3
drive = Drive::DriveService.new

# Auths with ENV vars:
# "GOOGLE_CLIENT_ID",
# "GOOGLE_CLIENT_EMAIL",
# "GOOGLE_ACCOUNT_TYPE", 
# "GOOGLE_PRIVATE_KEY"
auth = ::Google::Auth::ServiceAccountCredentials
  .make_creds(scope: 'https://www.googleapis.com/auth/drive')
drive.authorization = auth

list_files = drive.list_files()

Storage

Authorizers require a storage instance to manage long term persistence of access and refresh tokens. Two storage implementations are included:

  • Google::Auth::Stores::FileTokenStore
  • Google::Auth::Stores::RedisTokenStore

Custom storage implementations can also be used. See token_store.rb for additional details.

Supported Ruby Versions

This library is supported on Ruby 2.5+.

Google provides official support for Ruby versions that are actively supported by Ruby Core—that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. Currently, this means Ruby 2.5 and later. Older versions of Ruby may still work, but are unsupported and not recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.
