• Authorization
• Access!
Wednesday, May 6, 2009
Sign in with Twitter
• Consumer
• Request Token
• Authorize (Just Once)
• Access!

require 'oauth'require 'json'
# register your application at http://twitter.com/apps
consumer = OAuth::Consumer.new( 'mykey','mysecret', :site => 'http://twitter.com/')
request_token = consumer.get_request_tokenputs request_token.authorize_url
# go and visit the authorize URL
access_token = request_token.get_access_tokenme = JSON.parse(access_token.get('/account/verify_credentials.json').body)
me['screen_name'] # => 'mbleigh'
gem install oauth --version 0.3.2
