authentication - Facebook decoded signed_request contains extra data which isn't mentioned in the documentation -

-

i have facebook signed_request received subscribing auth.login event , after user logs in using facebook login button

after decode signed_request have following information in it:

{'issued_at': 1318492701,  'code': 'aqcxi5aiyytylfntkyhtkwdho02lp[truncated]',  'user_id': '100000xxxxxxxxx',  'algorithm': 'hmac-sha256'}

i cannot find in signed_request documentation. code , what's use?

i thought might used obtain authorization code stated in this thread along signed_request receive access token user in response login event.

this signed_request javascript sdk, right? code used sdk isn't server-side authentication. actually, update documentation reflect signed_request behaviors.
