I have a kind of one:

(it isn't on my github because I still haven't cleaned it up much)


The main function you want is fbGraph() which does a request via 
curl
and returns it as a Variant[string].

Variant[string] fbGraph(string[] info, string id, bool useCache = 
false, long maxCacheHours = 2) {



The info takes [null, access_token] (the first argument is 
obsolete, but so much
of my code passes an array that I didn't want to change it).



The second argument is the Facebook ID or the connection you 
want. For example

"adam.d.ruppe"

or "adam.d.ruppe/friends".



Then the cache function will save to a local file in /tmp (this 
thing assumes linux)
and pull from it for up to maxCacheHours instead of asking the 
network.




The getBasicDataFromVariant function is a convenience once to 
pull just very basic
info out of some requests, for example, /friends, which returns { 
"data" : [] } format.


I don't do a lot of posting, but postToFacebookWall does a wall 
message. It needs
your token to have publish_stream.




Getting permission is not in that file. I have functions for it, 
but they are in
one of my proprietary files so I have to make sure it is all 
sanitized before
I pull it out (which isn't easy since they save it to the app's 
database too).




The basic ideas though is to just redirect them here:


	return (stripWhitespace(
		"http://www.facebook.com/dialog/oauth/?
		  scope="~scopeWanted~"&
		  client_id="~appId~"&
		  redirect_uri="~std.uri.encodeComponent(action)
		 ~"&
		  response_type=code"
	));
