Easy way to send a message to an XMPP/Jabber conference room? (Shell or Python, Debian wheezy)

Question

What is an easy way to send a message to a XMPP/Jabber conference room? Either at the command line (Shell), or by using Python? Ideally, all commands and/or libraries should be available in Debian wheezy (or jessie), without using pip.

Answer 1

I had some problems in getting python-pyxmpp to work, maybe I was just to impatient. Anyway I found another solution, that worked for me, but using sleekxmpp for their website. The solution is not better (nor worse, I hope) than goncalopps, only I got it faster to work on Debian wheezy.

$ sudo apt-get install python-sleekxmpp

and here's the code:

import optparse
import sys
import time

import sleekxmpp


class MUCBot(sleekxmpp.ClientXMPP):
    def __init__(self, jid, password, room, nick, message):
        sleekxmpp.ClientXMPP.__init__(self, jid, password)
        self.room = room
        self.nick = nick
        self.add_event_handler("session_start", self.start)
        self.message = message

    def start(self, event):
        self.getRoster()
        self.sendPresence()
        self.plugin['xep_0045'].joinMUC(self.room, self.nick, wait=True)
        self.send_message(mto=self.room, mbody=self.message, mtype='groupchat')
        time.sleep(10)
        self.disconnect()


if __name__ == '__main__':
    op = optparse.OptionParser(usage='%prog [options] your message text')
    op.add_option("-j", "--jid", help="JID to use")
    op.add_option("-n", "--nick", help="MUC nickname")
    op.add_option("-p", "--password", help="password to use")
    op.add_option("-r", "--room", help="MUC room to join")
    opts, args = op.parse_args()

    if None in [opts.jid, opts.nick, opts.password, opts.room] \
       or len(args) < 1:
        op.print_help()
        sys.exit(1)

    xmpp = MUCBot(opts.jid, opts.password, opts.room, opts.nick,
                  " ".join(args))
    xmpp.register_plugin('xep_0030')  # Service Discovery
    xmpp.register_plugin('xep_0045')  # Multi-User Chat
    xmpp.register_plugin('xep_0199')  # XMPP Ping

    if xmpp.connect():
        xmpp.process(threaded=False)
    else:
        print "connect() failed"

Not sure, whether the plugin for xep_0199 is really needed.

First

apt-get install python-pyxmpp

Then, something like this

from pyxmpp.all import JID,Iq,Presence,Message,StreamError
from pyxmpp.jabber.muc import MucRoomState, MucRoomManager, MucRoomHandler
from pyxmpp.jabber.client import JabberClient
from pyxmpp.interface import implements
from pyxmpp.interfaces import *
from pyxmpp.streamtls import TLSSettings

def execute(user, password, tls_option, message_handler, idle_function, delay=1):
    global client, roomManager
    tls_settings= TLSSettings(require = True, verify_peer = (tls_option!='tls_no_verify'))
    client= Client(JID(user), password, tls_settings)
    client.connect()

    EchoHandler.message= message_handler
    roomManager = MucRoomManager(client.stream);
    roomManager.set_handlers()


def joinMUC( handler, room_jid, nick, password= None):
    global roomManager
    handler.password= password
    roomState = roomManager.join( room=JID(room_jid), nick=nick, handler=handler, history_maxchars=0, password= password )
    return roomState

from pyxmpp.jabber.muc import MucRoomHandler
roomManager= None
execute(username, password, 'tls_no_verify', process_message_callback, periodic_callback)
state= joinMUC( room_handler, "conferencename@mydomain.tld", user, passwd)
state.send_message("something spammy!")

I cannibalized this from some old code I had laying around, and I have no means to test it right now, but it should be a good starting point. Feel free to improve it

You could use Gajims remote_control for that task. You get the option for OMEMO-encrpytion on top.

First activate remote_control in Gajim in preferences -> advanced -> advanced config editor. Then restart Gajim.

Now you can send a message via terminal:

gajim-remote send_groupchat_message to@xmppserver.com 'Hello'

In python you can use subprocess, for example:

from subprocess import call
call(gajim-remote send_groupchat_message to@xmppserver.com 'Hello', shell=True)

Answer 4

I first used python-xmpp, but the package is not available any longer on Ubuntu 20.04, likely because it only seems to work with Python 2.x.

The python-sleekxmpp alternative in @user923543's answer by now is deprecated in favor of Slixmpp, a fork which takes full advantage of Python 3 and asyncio.

In Slixmpp's documentation, there's an example application that allows sending a single XMPP message. This works well on Ubuntu 20.04 / Python 3.8, but had errors on Ubuntu 18.04 / Python 3.6 (which also isn't officially supported).

I'm reproducing it here to avoid stale links; note that even though the header says This file is part of Slixmpp., it was not part of the package that I had installed:

        # will receive it.
        self.recipient = recipient
