gmail_xoauth Gem Version Dependency Status

Get access to Gmail IMAP and STMP via OAuth2 and OAuth 1.0a, using the standard Ruby Net libraries.

The gem supports 3-legged OAuth, and 2-legged OAuth for Google Apps Business or Education account owners.

Install

$ gem install gmail_xoauth

Usage for OAuth 2.0

Get your OAuth 2.0 tokens

You can generate and validate your OAuth 2.0 tokens thanks to the oauth2.py tool.

Create your API project in the Google APIs console, from the "API Access" tab.

$ python oauth2.py --generate_oauth2_token --client_id=364545978226.apps.googleusercontent.com --client_secret=zNrNsBzOOnQy8_O-8LkofeTR

IMAP OAuth 2.0

require 'gmail_xoauth'
imap = Net::IMAP.new('imap.gmail.com', 993, usessl = true, certs = nil, verify = false)
imap.authenticate('XOAUTH2', 'myemail@gmail.com', my_oauth2_token)
messages_count = imap.status('INBOX', ['MESSAGES'])['MESSAGES']
puts "Seeing #{messages_count} messages in INBOX"

SMTP OAuth 2.0

require 'gmail_xoauth'
smtp = Net::SMTP.new('smtp.gmail.com', 587)
smtp.enable_starttls_auto
smtp.start('gmail.com', 'myemail@gmail.com', my_oauth2_token, :xoauth2)
smtp.finish

Usage for OAuth 1.0a

== OAuth 1.0 has been officially deprecated as of April 20, 2012. ==

Get your OAuth 1.0a tokens

For testing, you can generate and validate your OAuth tokens thanks to the awesome xoauth.py tool.

$ python xoauth.py --generate_oauth_token --user=myemail@gmail.com

Or if you want some webapp code, check the gmail-oauth-sinatra project.

IMAP 3-legged OAuth 1.0a

For your tests, Gmail allows to set 'anonymous' as the consumer key and secret.

require 'gmail_xoauth'
imap = Net::IMAP.new('imap.gmail.com', 993, usessl = true, certs = nil, verify = false)
imap.authenticate('XOAUTH', 'myemail@gmail.com',
  :consumer_key => 'anonymous',
  :consumer_secret => 'anonymous',
  :token => '4/nM2QAaunKUINb4RrXPC55F-mix_k',
  :token_secret => '41r18IyXjIvuyabS/NDyW6+m'
)
messages_count = imap.status('INBOX', ['MESSAGES'])['MESSAGES']
puts "Seeing #{messages_count} messages in INBOX"

Note that the Net::IMAP#login method does not use support custom authenticators, so you have to use the Net::IMAP#authenticate method.

IMAP 2-legged OAuth 1.0a

require 'gmail_xoauth'
imap = Net::IMAP.new('imap.gmail.com', 993, usessl = true, certs = nil, verify = false)
imap.authenticate('XOAUTH', 'myemail@mydomain.com',
  :two_legged => true,
  :consumer_key => 'a',
  :consumer_secret => 'b'
)

SMTP 3-legged OAuth 1.0a

For your tests, Gmail allows to set 'anonymous' as the consumer key and secret.

require 'gmail_xoauth'
smtp = Net::SMTP.new('smtp.gmail.com', 587)
smtp.enable_starttls_auto
secret = {
  :consumer_key => 'anonymous',
  :consumer_secret => 'anonymous',
  :token => '4/nM2QAaunKUINb4RrXPC55F-mix_k',
  :token_secret => '41r18IyXjIvuyabS/NDyW6+m'
}
smtp.start('gmail.com', 'myemail@gmail.com', secret, :xoauth)
smtp.finish

Note that Net::SMTP#enable_starttls_auto is not defined in Ruby 1.8.6.

SMTP 2-legged OAuth 1.0a

require 'gmail_xoauth'
smtp = Net::SMTP.new('smtp.gmail.com', 587)
smtp.enable_starttls_auto
secret = {
    :two_legged => true,
  :consumer_key => 'a',
  :consumer_secret => 'b'
}
smtp.start('gmail.com', 'myemail@mydomain.com', secret, :xoauth)
smtp.finish

Compatibility

Tested on Ruby MRI 1.8.6, 1.8.7, 1.9.1, 1.9.2 and 1.9.3. Feel free to send me a message if you tested this code with other implementations of Ruby.

The only external dependency is the oauth gem.

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
