I’m developing a new Facebook Canvas application within an iFrame and trying to authorize users. The new OAuth api recommends I do a redirect to the following to authorize a user in my app:
https://graph.facebook.com/oauth/authorize?
client_id=…&
redirect_uri=http://www.example.com/oauth_redirect
However this produces a weird problem where a full Facebook page requesting permissions from the user is rendered within the iFrame itself (i.e. facebook within Facebook). Does anyone know how to solve this with the new OAuth API as I don’t want to start using old REST API methods.
Even I had the same issue and I posted it in facebook forum. The moderator informed me that it is an issue for which there is no solution as of now. Take a look at this thread – http://forum.developers.facebook.com/viewtopic.php?id=56590
