MiniFB.parse_cookie_information returns nil

[George Faraj]

Hello,

I'm having a problem with the facebook cookies right now. I didn't use to have this problem before yesterday, and I haven't been able to get it to work since. 

Here's the situation:

I have a <fb:login_button> in my pages. I'm subscribing to the auth.login facebook API event, that refreshes the page when the user logs in. Currently, if the user logs in using this button, the page is refreshed correctly. My app calls check_facebook_login (below) and cannot parse the cookie correctly. The parse_cookie_information method returns nil. As I said, this worked perfectly before yesterday, so I'm not sure what is going on.

Here's my code:

  def check_facebook_login

    begin

      fb_cookie = MiniFB.parse_cookie_information(Settings.facebook.app_id, cookies)

      Rails.logger.info 'verifying cookie: ' + cookies.inspect + ' fb_cookie: ' + fb_cookie.inspect

      if MiniFB.verify_cookie_signature(Settings.facebook.app_id, Settings.facebook.app_secret, cookies)

        Rails.logger.info 'cookie verified, creating session'

        @_fb_session = MiniFB::Session.new(Settings.facebook.api_key, Settings.facebook.app_secret, fb_cookie['session_key'], fb_cookie['uid'])

        Rails.logger.info 'looking for existing user'

        user = User.find_by_facebook_id(@_fb_session.uid)

        if user.nil?

          Rails.logger.info 'registering new user'

          user = User.new

          user.name = @_fb_session.user['name']

          user.facebook_id = @_fb_session.user['uid']

          user.save

        end

        set_current_user(user)

      elsif is_logged_in?

        Rails.logger.info 'could not verify cookie, logged out'

        set_current_user(nil)

      end

    rescue MiniFB::FaceBookError => error

      Rails.logger.info error.message

      Rails.logger.info error.backtrace.inspect

      set_current_user(nil)

    end

  end

Logger output:

Started GET "/posts" for 127.0.0.1 at 2011-01-29 10:28:22 -0800

Any ideas why the cookies dont include the facebook ones? What can I do to fix this?

Thanks!

U figure this out?

[George Faraj]

Yes, thanks for checking in. Stupid system time had automatically changed to a time in the future, so the cookies were expiring immediately. Thanks!
