FBGraph supports the most (no analytics yet) features of Facebook Open Graph API: developers.facebook.com/docs/reference/api/
Without a token (for authorization)
client = FBGraph::Client.new(:client_id => 'client_id',:secret_id =>'secret_id')
With a token
client = FBGraph::Client.new(:client_id => 'client_id',:secret_id =>'secret_id' ,:token => token)
All methods are chainable
Examples:
client.selection.me.photos.until(Time.now.to_s).since(3.days.ago).limit(10).info
client.selection.user('id').videos.offset(10).info
client.search.query('q').on('users').limit(20).info
returns the authorize url
redirect_to client.authorization.authorize_url(:redirect_uri => callback_url , :scope => 'email,user_photos,friends_photos')
process the callback and returns the access token
access_token = client.authorization.process_callback(params[:code], :redirect_uri => callback_url)
Facebook send a segned_request as a parameter. Can be decoded with the method parse_signed_request of FBGraph::Canvas module
> FBGraph::Canvas.parse_signed_request(params[:signed_request])
All objects and their connections can be accesed
Examples:
client.selection.me.home.info!
client.selection.user('id').photos.info!
client.selection.photo('id').comments.info!
client.selection.page('id').info!
