I'm trying to authenticate users coming to my site from a click on an opengraph action in facebook.
I've generate the action successfully with the following code. This goes out to my timeline successfully. So far, so good.
require 'cgi'
client_id ="CLIENT_ID"
client_secret = "CLIENT_SECRET"
recipe = "http://foodonthetable.shadr.us/recipes/1007-spanish-chicken-and-rice"
access_token = "LONGACCESSTOKEN"
# PUBLISH
result = `curl -F access_token=#{access_token} -F recipe=#{recipe} https://graph.facebook.com/me/foodonthetable_mrh:plan_to_cook`
puts result
When I click on the link in the timeline, I'm taken to the following URL. This is where
I start having issues. Basically, I want to recognize the user coming in
through this link and log them in (or create a new user). I have
authenticated referrals turned on, and I'm receiving the code parameter as
expected.
http://foodonthetable.shadr.us/recipes/1007-spanish-chicken-and-rice?fb_action_ids=384156608318085&fb_action_types=foodonthetable_mrh%3Aplan_to_cook&fb_source=timeline_og&action_object_map=%7B%22384156608318085%22%3A10151004406923956%7D&code=AQAPExNw7MHkxcLTEi5L24iD79pVa-WYxyhBA_bhdWLCM0PCGDuPjh1WqmAyd3_O3_LSjYzPawrinHNP3nv9BCMB_XuTnr8De8xQ2AwXqCaeHUzZUPm2MPyQ_eodOC9-YtjkvXm_PzRX3JG58khalT3AJjVuZvKHn5hWGDSohXLRbHGxW-vOg_Whm3mt_WUkdd0#_=_
However, when I try to get the auth_token using this code, I'm not able to.
I've tried using a couple of different versions of the redirect_uri thinking
that might be the problem (based on other posts) but nothing seems to work.
redirect_uri = "http://foodonthetable.shadr.us/recipes/1007-spanish-chicken-and-rice"
redirect_uri = "http://foodonthetable.shadr.us/facebook_connect/connect"
code = "AQAPExNw7MHkxcLTEi5L24iD79pVa-WYxyhBA_bhdWLCM0PCGDuPjh1WqmAyd3_O3_LSjYzPawrinHNP3nv9BCMB_XuTnr8De8xQ2AwXqCaeHUzZUPm2MPyQ_eodOC9-YtjkvXm_PzRX3JG58khalT3AJjVuZvKHn5hWGDSohXLRbHGxW-vOg_Whm3mt_WUkdd0"
result = `curl -F client_id=#{client_id} -F redirect_uri=#{redirect_uri} -F client_secret=#{client_secret} -F code=#{code} https://graph.facebook.com/oauth/access_token`
puts result
No matter what I do here, I always get the following error:
{"error":{"message":"Error validating verification code.","type":"OAuthException","code":100}}
Any help would be appreciated.
