Please Someone suggest me the proper way to integrate Facebook Chat

回答1:

It's a really old question, but I just faced the same problem and posting this in case anyone faces the same problem.

I had not installed pyopenssl, and installing it fixed the problem immediately.



回答2:

You need to check several things:

  • The error returned by punjab is remote-connection-failed. It means it could not open a connection to chat.facebook.com. Your punjab logs does not seem to match, as you do not have any attempt to connect to Facebook.
  • You might hurt cross domain problem and that might be the reason why you client does not connect to Punjab. Punjab is running on port 5280 and your client is served on port 80. It is different service and your browser might prevent connecting back to port 5280 from a client served on port 80. Check your Javascript browser log. I would expect an error there.
  • Facebook does not support standard authentication when using proxy. You will need a library that supports X-FACEBOOK-PLATFORM SASL authentication mechanism. See: http://developers.facebook.com/docs/chat/
