Programming Jabber

JabberRPCRequester

Now that we’ve got our Jabber-RPC responder all set up, it’s time to turn our attention to our requester, JabberRPCRequester, shown in Example 10-12. This is a Python script that uses the Jabberpy library and Pythonware’s xmlrpclib library. It’s a pretty simple affair.

Example 10-12. The JabberRPCRequester script, written in Python

import jabber
import xmlrpclib
import string
import sys

Server   = 'qmacro.dyndns.org'
Username = 'client'
Password = 'pass'
Resource = 'jrpc-client'
Endpoint = '[e-mail]/jrpc-server';
Method   = 'examples.getCountyName';

county   = string.atoi(sys.argv[1])

con = jabber.Client(host=Server)
try:
    con.connect()
except IOError, e:
    print "Couldn't connect: %s" % e
    sys.exit(0)

con.auth(Username,Password,Resource)

request = xmlrpclib.dumps(((county),),
    methodname=Method);

iq = jabber.Iq(to=Endpoint, type="set')
iq.setQuery('jabber:iq:rpc')
iq.setQueryPayload(request)

result = con.SendAndWaitForResponse(iq)

if result.getType() == 'result':
    response = str(result.getQueryPayload())
    parms, func = xmlrpclib.loads(response)
    print parms[0]
else:
    print "Could not complete call"

con.disconnect()
