OAuth 1.0 and 2.0 strategies for the OmniAuth gem.

To get just OAuth functionality:

gem install oa-oauth

For the full auth suite:

gem install omniauth

Use the strategy as a middleware in your application:

require 'omniauth/oauth'

use OmniAuth::Strategies::Twitter, 'consumer_key', 'consumer_secret'

Then simply direct users to ‘/auth/twitter’ to have them authenticate via Twitter.

If you want to allow multiple providers, use the OmniAuth Builder:

require 'omniauth/oauth'

use OmniAuth::Builder do
  provider :twitter, 'consumer_key', 'consumer_secret'
  provider :facebook, 'client_id', 'client_secret'
end
