I digged much into internet, but being newbie, couldn't do much. I have summed up the following : Facebook Chat can be used via two Authentication (via Facebook Chat API official documentation) :
1> X-FACEBOOK-PLATFORM 2> DIGEST-MD5
1> X-FACEBOOK-PLATFORM Method has very less documentation, none being official, closest using pyfacebook & pyxmpp (The official facebook chat api page has a reference at the end). Implementing the both to GAE is another headache, apart from the debug problems suffered hence. The creation of apps and using its ID as stated in some resources is not a problem though. I found a nice GAE walkthrough of pyfacebook on riccomini.name/Topics/Web/GoogleAppEngine/FacebookConnect/
2> DIGEST-MD5 is the common method of username - password which can be carries out by any xmpp client. So i though i could use a XMPP python client library like xmpppy which suited me best (as i don't need advanced functions)
Coming staraight to my question : is my inference correct? I am thinking to proceed via Method 2 (Im well aware of the security risks involved in MD5 crypting of password, please don't remind me of that). I could find no refence of using xmpppy with GAE, so am I proceeding correct?
Could anyone provide me a reference of xmpppy used along with GAE ??
(I'm sorry if i was unclear. Cant help, i am no silicon valley engineer but a simple student of age 15yrs)
You can't connect to external XMPP servers using App Engine, so if Facebook requires it for chat integration, this isn't possible.
