问题
I am using Koala to handle FB calls. Everything is working fine except I can't figure out how to deauthorize a user's FB permissions.
The equivalente REST call would be to:
DELETE /{user-id}/permissions/{permission-name}
The Koala wiki indicates all REST calls are supported via:
@rest = Koala::Facebook::API.new(oauth_access_token)
@rest.fql_query(my_fql_query) # convenience method
@rest.fql_multiquery(fql_query_hash) # convenience method
@rest.rest_call("stream.publish", arguments_hash) # generic version
but this doesn't tell me much.
I would prefer to use Koala as I have app secret security enabled and generating app_secret_proof for plain FB REST calls is a major hassle. Koala handles it transparently.

Figured it out.
After instantiating the @rest object:
@rest = Koala::Facebook::API.new(oauth_access_token, app_secret)
you can check out its methods via:
@rest.methods
and you'll notice it returns RESTful methods like #get_object, #put object, and our winner: #delete_object.
Then it's just a matter of doing:
@rest.delete_object("me/permissions")
success!
