Simple XMPP bot on python

Question

I have the simple code of XMPP bot by python and http://xmpppy.sourceforge.net/

#!/usr/bin/python
# -*- coding: utf-8 -*-

import xmpp
import urllib2
import ConfigParser

config = ConfigParser.ConfigParser()
config.read('ipbot.conf')

##########################
user= (config.get('account', 'login'))
password=(config.get('account', 'password'))
presence=(config.get('presence','presence'))
##########################

jid=xmpp.protocol.JID(user)
client=xmpp.Client(jid.getDomain())
client.connect()
client.auth(jid.getNode(),password)

################Parse IP##################
strURL='http://api.wipmania.com/'
f = urllib2.urlopen(urllib2.Request(strURL))
response = f.read()
ipget= response.split("<br>")
f.close()
#############################################

def status(xstatus):
    status=xmpp.Presence(status=xstatus,show=presence,priority='1')
    client.send(msging)

def message(conn,mess):

  global client

  if ( mess.getBody() == "ip" ):
    client.send(xmpp.protocol.Message(mess.getFrom(),ipget[1]+" => "+ipget[0]))#Send IP

client.RegisterHandler('message',message)

client.sendInitPresence()

while True:
    client.Process(1)

Please, tell me, how to translate this code to use http://wokkel.ik.nu/ and twistedmatrix.com/ Thanks a lot.

Answer 1

The following code should do it. A few notes:

• Wokkel uses so-called subprotocol handlers to cover support for specific subprotocols, usually split up by conceptual feature, by namespace or per XEP.
• XMPPClient is a so-called stream manager that establishes connections, and takes care of authentication with the server. It works with the hooked-up subprotocol handlers to process traffic with the XML stream it manages. It automatically reconnects if the connection has been lost.
• This example defines one new handler to process incoming messages.
• Unlike the original code, here the request to retrieve the IP address is done for each incoming message with ip in the body.
• In the original code, status was never called. I now the use PresenceProtocol subprotocol handler to send out the presence each time a connection has been established and authentication has taken place.

The example is a so-called Twisted Application, to be started using twistd, as mentioned in the docstring. This will daemonize the process and logs go to twisted.log. If you specify -n (before -y), it will not detach and log to the console instead.
