The OAuth Shuffle

• Consumer

• Request Token

• Authorization

• Access!


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

Caveat OAuth

• The Advisory (no callbacks)

• Solution: One Dev App

• Read/Write Inconsistency

• Solution: Delete and Recreate
