Facebook publish actions - Values from preview obj

问题:

Ok I am trying to publish an action on facebook from my mobile game.

I have set up an object (say "picture") and an action (say "draw") I have set up an external web page whose meta data describes the object "picture"

Now I send a post request from my game with parameters

  • access_token = token
  • picture = the external link of the object

The action is published. But not with the values I give in my external page's meta data. The action published has the values which i gave to the PREVIEW OBJECT of the object "picture"

In short, the action published takes its values (like og:title, og:image, etc) from the PREVIEW OBJECT of "picture" and not from the external link's meta data.

Hope that makes sense.

I'm pretty sure the solution would be something really simple, but I can't figure out what the problem is. Please help.
