Question

tornado accepts OAuth1, 2 and OpenID, and from search in SO: OpenID is just to login, OAuth is to tell other service (for example Facebook): ok, come to my account, and use what i give you the permission to use.

so because of this, how to make a simple “hello world” print in my Facebook wall, because if this will work, then one will avoid using a pubsub in his application, and let Facebook display notification (since there is a great chance that a user have Facebook account).

NB: the example the ships with Tornado is to “how to see my notification from localhost”

Answer 1

here is how, you need this: Python-Facebook SDK and you add this to the facebook example, dont know if it is non blocking, but i see the self._on_stream which i think it’s a callback, so it is non-blocking?

import facebook 

class MainHandler(BaseHandler, tornado.auth.FacebookGraphMixin): 
    @tornado.web.authenticated 
    @tornado.web.asynchronous 
    def get(self): 
        self.facebook_request("/me/home", self._on_stream, access_token=self.current_user["access_token"]) 
    a = self.current_user["access_token"] 
    print a # for debug
    graph = facebook.GraphAPI(a) 
    graph.put_object("me", "feed", message="I am writing on my wall!") 

NB: you can post a message only one time in 5 minutes
