xmpppy and Facebook Chat Integration
Question: I'm trying to create a very simple script that uses python's xmpppy to send a
message over facebook chat.

    
    
    import xmpp
    FACEBOOK_ID = "username@chat.facebook.com"
    PASS = "password"
    SERVER = "chat.facebook.com"
    jid=xmpp.protocol.JID(FACEBOOK_ID)
    C=xmpp.Client(jid.getDomain(),debug=[])
    if not C.connect((SERVER,5222)):
        raise IOError('Can not connect to server.')
    if not C.auth(jid.getNode(),PASS):
        raise IOError('Can not auth with server.')
    C.send(xmpp.protocol.Message("friend@chat.facebook.com","Hello world",))
    

This code works to send a message via gchat, however when I try with facebook
I recieve this error:

An error occurred while looking up _xmpp-client._tcp.chat.facebook.com

When I remove @chat.facebook.com from the FACEBOOK_ID I get this instead:

    
    
    File "gtalktest.py", line 11, in 
        if not C.connect((SERVER,5222)):
      File "/home/john/xmpppy-0.3.1/xmpp/client.py", line 195, in connect
        if not CommonClient.connect(self,server,proxy,secure,use_srv) or secureNone and not secure: return self.connected
      File "/home/john/xmpppy-0.3.1/xmpp/client.py", line 179, in connect
        if not self.Process(1): return
      File "/home/john/xmpppy-0.3.1/xmpp/dispatcher.py", line 302, in dispatch
        handler['func'](session,stanza)
      File "/home/john/xmpppy-0.3.1/xmpp/dispatcher.py", line 214, in streamErrorHandler
        raise exc((name,text))
    xmpp.protocol.HostUnknown: (u'host-unknown', '')
    

I also notice any time I import xmpp I get the following two messages when
running:

    
    
    /home/john/xmpppy-0.3.1/xmpp/auth.py:24: DeprecationWarning: the sha module is deprecated; use the hashlib module instead
      import sha,base64,random,dispatcher
    /home/john/xmpppy-0.3.1/xmpp/auth.py:26: DeprecationWarning: the md5 module is deprecated; use hashlib instead
      import md5
    

I'm fairly new to solving these kinds of problems, and advise, or links to
resources that could help me move forward in solve these issues would be
greatly appreciated. Thanks for reading!


Answer: I also started the same project, and was trapped into same problem. I found
the solution too. You have to write the UserName of facebook (Hence You must
opt one Username) and that too in small Caps. This is the most important part.
Most probably you too like me would not be writing it in small Caps.
