How do web apps publish Facebook news and notification feeds without user involvement in the FB app?

Question

I have an existing Rails web application that I would like to integrate with Facebook, so when a user takes actions in my applications, news containing external links is later sent to the users’s wall / channel with a daemon summing up the latest Events. Currently, I do not need a separate single, etc., Just the ability to send updates.

I would also like to be able to send notifications to friends of users if they also use the application, but I would be pleased only with the functionality of the news feeds.

I am working on a pragmatic book by Facebook Platform Development programmer Michael Mangino, which uses the facebooker plugin, and the beginning of the book says the following:

Facebook uses sessions to verify that our application is acting on behalf of the active user. When we want to send a notification on behalf of our user, we will provide Facebook with information about user sessions. Facebook will verify that the session actually belongs to the requestor and also verify that the User has been active on ours for the past hour. Facebook uses the session to prevent the application from taking action on behalf of a user who is not active using them

What is considered "active in the application" and what does it mean in this context? I saw other applications that do things such as automatically placing RSS feeds in a user’s profile, so it looks like they have similar applications where the only interaction is a one-time installation and setup.

How do these applications work, and is it possible to get this functionality from facebooker?

Answer 1

user = session[:facebook_session].user
user.publish_to(user, :message => "action!",
                            :attachment => {:name => "name of attachment",
                                            :href => "http://link.where.attachment.description.should.link.to",
                                            :media => [{:type => "image",
                                                        :src => "http://link.to.where.attachment.is",
                                                        :href => "http://link.where.attachment.description.should.link.to"}]},
                            :action_links => [{:text => 'Action Link Title',
                                               :href => 'http://www.action.link'}])

"publish_stream". , . http://wiki.developers.facebook.com/index.php/Extended_permissions

Facebooker:: User.publish_to. . Facebooker:: Session.send_notification ( )

99% , facebooker API facebook , , . , .

, facebooker, , Facebooker:: Session Facebooker:: User.

fbsession = Facebooker::Session.create(api_key, secret_key)
fbuser = Facebooker::User.new(<Facebooker user id>, fbsession)

#requires "publish_stream" extended permission
fbuser.publish_to(fbuser, :message => "This is a post")

fbsession.send_notification(fbuser.id, "<fb:fbml>some sweet fbml</fb:fbml>")

Answer 3

I am in a similar situation ... here are my current findings. I hope they help.

To get the URL that the user must click to grant access to the publication

facebook_session = Facebooker::Session.create
facebook_session.permission_url('publish_stream')

To then send a message to the user profile

facebook_session = Facebooker::Session.create
facebook_session.post 'facebook.stream.publish', :uid => [UID], :message => 'test'

I am sure that the above method has limitations, but late, I am tired and I will pick it back in the morning. :-)
