Question

there is Facebook OAuth2 module in Tornado, but i dont get the idea behind it:
the example will get the “stream” from my wall, but because i want to see how to post on the wal using Tornado, i found a another Python module, but this one dont use the OAuth, but requires another key: a Token, and when i go to Facebook and generate it, it give me two application: the one that i created from Tornado, and the second one is “Graph API Explorer” that allowed me to generate a long key in “Extended Permission”, but i still cant post on my Facebook Wall.

Update: here is the code iused with the Python-Facebook module:

import facebook

graph=facebook.GraphAPI("____")
profile = graph.get_object("me")
graph.put_object("me", "feed", message="I am writing on my wall!")
print profile

and gives me this error:

facebook.GraphAPIError: Error validating access token: This may be because the user logged out or may be due to a system error.

Update2: it worked, it seems that i must wait a certain time to validate the save the Token in their database?

so my question is still: what is the difference between the Token and the OAuth Acces in Tornado. because am planning to use a notification everytime the application updates to Facebook Users (posting the update in the page’s wall to be seen by the users of that page)

Update3: it seems that Facebook dont allow to post more than one post by a period of time, else i got an error:

Traceback (most recent call last):
File "C:\Users\toto\Desktop\tooooooooooorfacebook.py", line 5, in <module>
graph.put_object("me", "feed", message="this is a test")
File "C:\Python27\lib\site-packages\facebook.py", line 140, in put_object
post_args=data)
File "C:\Python27\lib\site-packages\facebook.py", line 298, in request
raise GraphAPIError(response)
facebook.GraphAPIError: (#506) Duplicate status message

Answer 1

am sorry for asking it, now i think it got the difference:

since there is time limit to the Token, so it will be a hard task to generate it everytime by the Admin, this what Tornado do, it asks for the Token for every access, so it will get the Refreshed one.

self.facebook_request("/me/home", self._on_stream, access_token=self.current_user["access_token"])

so it gets everytime the Token.

thank you again and sorry again.
