SleekXMPP Quickstart - Echo Bot
|
||||||
|
===============================
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
If you have any issues working through this quickstart guide
|
||||||
|
or the other tutorials here, please either send a message to the
|
||||||
|
`mailing list <http://groups.google.com/group/sleekxmpp-discussion>`_
|
||||||
|
or join the chat room at `sleek@conference.jabber.org
|
||||||
|
<xmpp:sleek@conference.jabber.org?join>`_.
|
||||||
|
|
||||||
|
If you have not yet installed SleekXMPP, do so now by either checking out a version
|
||||||
|
from `Github <http://github.com/fritzy/SleekXMPP>`_, or installing it using ``pip``
|
||||||
|
or ``easy_install``.
|
||||||
|
|
||||||
|
.. code-block:: sh
|
||||||
|
|
||||||
|
pip install sleekxmpp # Or: easy_install sleekxmpp
|
||||||
|
|
||||||
|
|
||||||
|
As a basic starting project, we will create an echo bot which will reply to any
|
||||||
|
messages sent to it. We will also go through adding some basic command line configuration
|
||||||
|
for enabling or disabling debug log outputs and setting the username and password
|
||||||
|
for the bot.
|
||||||
|
|
||||||
|
For the command line options processing, we will use the built-in ``optparse``
|
||||||
|
module and the ``getpass`` module for reading in passwords.
|
||||||
|
|
||||||

TL;DR Just Give Me the Code
|
||||||
|
---------------------------
|
||||||
|
As you wish: :ref:`the completed example <echobot_complete>`.
|
||||||
|
|
||||||
|
Overview
|
||||||
|
--------
|
||||||
|
|
||||||
|
To get started, here is a brief outline of the structure that the final project will have:
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
#!/usr/bin/env python
|
||||||
|
# -*- coding: utf-8 -*-
|
||||||
|
|
||||||
|
import sys
|
||||||
|
import logging
|
||||||
|
import getpass
|
||||||
|
from optparse import OptionParser
|
||||||
|
|
||||||
|
import sleekxmpp
|
||||||
|
|
||||||
|
'''Here we will create out echo bot class'''
|
||||||
|
|
||||||
|
if __name__ == '__main__':
|
||||||
|
'''Here we will configure and read command line options'''
|
||||||
|
|
||||||
|
'''Here we will instantiate our echo bot'''
|
||||||
|
|
||||||
|
'''Finally, we connect the bot and start listening for messages'''
|
||||||
|
|
||||||
|
Default Encoding
|
||||||
|
----------------
|
||||||
|
XMPP requires support for UTF-8 and so SleekXMPP must use UTF-8 as well. In
|
||||||
|
Python3 this is simple because Unicode is the default string type. For Python2.6+
|
||||||
|
the situation is not as easy because standard strings are simply byte arrays and
|
||||||
|
use ASCII. We can get Python to use UTF-8 as the default encoding by including:
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
if sys.version_info < (3, 0):
|
||||||
|
reload(sys)
|
||||||
|
sys.setdefaultencoding('utf8')
|
||||||
|
|
||||||
|
.. warning::
|
||||||
|
|
||||||
|
Until we are able to ensure that SleekXMPP will always use Unicode in Python2.6+, this
|
||||||
|
may cause issues embedding SleekXMPP into other applications which assume ASCII encoding.
|
||||||
|
|
||||||
|
Creating the EchoBot Class
|
||||||
|
--------------------------
|
||||||
|
|
||||||
|
There are three main types of entities within XMPP — servers, components, and
|
||||||
|
clients. Since our echo bot will only be responding to a few people, and won't need
|
||||||
|
to remember thousands of users, we will use a client connection. A client connection
|
||||||
|
is the same type that you use with your standard IM client such as Pidgin or Psi.
|
||||||
|
|
||||||
|
SleekXMPP comes with a :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>` class
|
||||||
|
which we can extend to add our message echoing feature. :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>`
|
||||||
|
requires the parameters ``jid`` and ``password``, so we will let our ``EchoBot`` class accept those
|
||||||
|
as well.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
class EchoBot(sleekxmpp.ClientXMPP):
|
||||||
|
|
||||||
|
def __init__(self, jid, password):
|
||||||
|
super(EchoBot, self).__init__(jid, password)
|
||||||
|
|
||||||
|
Handling Session Start
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
The XMPP spec requires clients to broadcast its presence and retrieve its roster (buddy list) once
|
||||||
|
it connects and establishes a session with the XMPP server. Until these two tasks are completed,
|
||||||
|
some servers may not deliver or send messages or presence notifications to the client. So we now
|
||||||
|
need to be sure that we retrieve our roster and send an initial presence once the session has
|
||||||
|
started. To do that, we will register an event handler for the :term:`session_start` event.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
def __init__(self, jid, password):
|
||||||
|
super(EchoBot, self).__init__(jid, password)
|
||||||
|
|
||||||
|
self.add_event_handler('session_start', self.start)
|
||||||
|
|
||||||
|
|
||||||
|
Since we want the method ``self.start`` to execute when the :term:`session_start` event is triggered,
|
||||||
|
we also need to define the ``self.start`` handler.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
def start(self, event):
|
||||||
|
self.send_presence()
|
||||||
|
self.get_roster()
|
||||||
|
|
||||||
|
.. warning::
|
||||||
|
|
||||||
|
Not sending an initial presence and retrieving the roster when using a client instance can
|
||||||
|
prevent your program from receiving presence notifications or messages depending on the
|
||||||
|
XMPP server you have chosen.
|
||||||
|
|
||||||
|
Our event handler, like every event handler, accepts a single parameter which typically is the stanza
|
||||||
|
that was received that caused the event. In this case, ``event`` will just be an empty dictionary since
|
||||||
|
there is no associated data.
|
||||||
|
|
||||||
|
Our first task of sending an initial presence is done using :meth:`send_presence <sleekxmpp.basexmpp.BaseXMPP.send_presence>`.
|
||||||
|
Calling :meth:`send_presence <sleekxmpp.basexmpp.BaseXMPP.send_presence>` without any arguments will send the simplest
|
||||||
|
stanza allowed in XMPP:
|
||||||
|
|
||||||
|
.. code-block:: xml
|
||||||
|
|
||||||
|
<presence />
|
||||||
|
|
||||||
|
|
||||||
|
The second requirement is fulfilled using :meth:`get_roster <sleekxmpp.clientxmpp.ClientXMPP.get_roster>`, which
|
||||||
|
will send an IQ stanza requesting the roster to the server and then wait for the response. You may be wondering
|
||||||
|
what :meth:`get_roster <sleekxmpp.clientxmpp.ClientXMPP.get_roster>` returns since we are not saving any return
|
||||||
|
value. The roster data is saved by an internal handler to ``self.roster``, and in the case of a :class:`ClientXMPP
|
||||||
|
<sleekxmpp.clientxmpp.ClientXMPP>` instance to ``self.client_roster``. (The difference between ``self.roster`` and
|
||||||
|
``self.client_roster`` is that ``self.roster`` supports storing roster information for multiple JIDs, which is useful
|
||||||
|
for components, whereas ``self.client_roster`` stores roster data for just the client's JID.)
|
||||||
|
|
||||||
|
It is possible for a timeout to occur while waiting for the server to respond, which can happen if the
|
||||||
|
network is excessively slow or the server is no longer responding. In that case, an :class:`IQTimeout
|
||||||
|
<sleekxmpp.exceptions.IQTimeout>` is raised. Similarly, an :class:`IQError <sleekxmpp.exceptions.IQError>` exception can
|
||||||
|
be raised if the request contained bad data or requested the roster for the wrong user. In either case, you can wrap the
|
||||||
|
``get_roster()`` call in a ``try``/``except`` block to retry the roster retrieval process.
|
||||||
|
|
||||||
|
The XMPP stanzas from the roster retrieval process could look like this:
|
||||||
|
|
||||||
|
.. code-block:: xml
|
||||||
|
|
||||||
|
<iq type="get">
|
||||||
|
<query xmlns="jabber:iq:roster" />
|
||||||
|
</iq>
|
||||||
|
|
||||||
|
<iq type="result" to="echobot@example.com" from="example.com">
|
||||||
|
<query xmlns="jabber:iq:roster">
|
||||||
|
<item jid="friend@example.com" subscription="both" />
|
||||||
|
</query>
|
||||||
|
</iq>
|
||||||
|
|
||||||
|
Responding to Messages
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
Now that an ``EchoBot`` instance handles :term:`session_start`, we can begin receiving and
|
||||||
|
responding to messages. Now we can register a handler for the :term:`message` event that is raised
|
||||||
|
whenever a messsage is received.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
def __init__(self, jid, password):
|
||||||
|
super(EchoBot, self).__init__(jid, password)
|
||||||
|
|
||||||
|
self.add_event_handler('session_start', self.start)
|
||||||
|
self.add_event_handler('message', self.message)
|
||||||
|
|
||||||
|
|
||||||
|
The :term:`message` event is fired whenever a ``<message />`` stanza is received, including for
|
||||||
|
group chat messages, errors, etc. Properly responding to messages thus requires checking the
|
||||||
|
``'type'`` interface of the message :term:`stanza object`. For responding to only messages
|
||||||
|
addressed to our bot (and not from a chat room), we check that the type is either ``normal``
|
||||||
|
or ``chat``. (Other potential types are ``error``, ``headline``, and ``groupchat``.)
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
def message(self, msg):
|
||||||
|
if msg['type'] in ('normal', 'chat'):
|
||||||
|
msg.reply("Thanks for sending:\n%s" % msg['body']).send()
|
||||||
|
|
||||||
|
Let's take a closer look at the ``.reply()`` method used above. For message stanzas,
|
||||||
|
``.reply()`` accepts the parameter ``body`` (also as the first positional argument),
|
||||||
|
which is then used as the value of the ``<body />`` element of the message.
|
||||||
|
Setting the appropriate ``to`` JID is also handled by ``.reply()``.
|
||||||
|
|
||||||
|
Another way to have sent the reply message would be to use :meth:`send_message <sleekxmpp.basexmpp.BaseXMPP.send_message>`,
|
||||||
|
which is a convenience method for generating and sending a message based on the values passed to it. If we were to use
|
||||||
|
this method, the above code would look as so:
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
def message(self, msg):
|
||||||
|
if msg['type'] in ('normal', 'chat'):
|
||||||
|
self.send_message(mto=msg['from'],
|
||||||
|
mbody='Thanks for sending:\n%s' % msg['body'])
|
||||||
|
|
||||||
|
Whichever method you choose to use, the results in action will look like this:
|
||||||
|
|
||||||
|
.. code-block:: xml
|
||||||
|
|
||||||
|
<message to="echobot@example.com" from="someuser@example.net" type="chat">
|
||||||
|
<body>Hej!</body>
|
||||||
|
</message>
|
||||||
|
|
||||||
|
<message to="someuser@example.net" type="chat">
|
||||||
|
<body>Thanks for sending:
|
||||||
|
Hej!</body>
|
||||||
|
</message>
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
XMPP does not require stanzas sent by a client to include a ``from`` attribute, and
|
||||||
|
leaves that responsibility to the XMPP server. However, if a sent stanza does
|
||||||
|
include a ``from`` attribute, it must match the full JID of the client or some
|
||||||
|
servers will reject it. SleekXMPP thus leaves out the ``from`` attribute when replying
|
||||||
|
using a client connection.
|
||||||
|
|
||||||
|
Command Line Arguments and Logging
|
||||||
|
----------------------------------
|
||||||
|
|
||||||
|
While this isn't part of SleekXMPP itself, we do want our echo bot program to be able
|
||||||
|
to accept a JID and password from the command line instead of hard coding them. We will
|
||||||
|
use the ``optparse`` module for this, though there are several alternative methods, including
|
||||||
|
the newer ``argparse`` module.
|
||||||
|
|
||||||
|
We want to accept three parameters: the JID for the echo bot, its password, and a flag for
|
||||||
|
displaying the debugging logs. We also want these to be optional parameters, since passing
|
||||||
|
a password directly through the command line can be a security risk.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
if __name__ == '__main__':
|
||||||
|
optp = OptionParser()
|
||||||
|
|
||||||
|
optp.add_option('-d', '--debug', help='set logging to DEBUG',
|
||||||
|
action='store_const', dest='loglevel',
|
||||||
|
const=logging.DEBUG, default=logging.INFO)
|
||||||
|
optp.add_option("-j", "--jid", dest="jid",
|
||||||
|
help="JID to use")
|
||||||
|
optp.add_option("-p", "--password", dest="password",
|
||||||
|
help="password to use")
|
||||||
|
|
||||||
|
opts, args = optp.parse_args()
|
||||||
|
|
||||||
|
if opts.jid is None:
|
||||||
|
opts.jid = raw_input("Username: ")
|
||||||
|
if opts.password is None:
|
||||||
|
opts.password = getpass.getpass("Password: ")
|
||||||
|
|
||||||
|
Since we included a flag for enabling debugging logs, we need to configure the
|
||||||
|
``logging`` module to behave accordingly.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
if __name__ == '__main__':
|
||||||
|
|
||||||
|
# .. option parsing from above ..
|
||||||
|
|
||||||
|
logging.basicConfig(level=opts.loglevel,
|
||||||
|
format='%(levelname)-8s %(message)s')
|
||||||
|
|
||||||
|
|
||||||
|
Connecting to the Server and Processing
|
||||||
|
---------------------------------------
|
||||||
|
There are three steps remaining until our echo bot is complete:
|
||||||
|
1. We need to instantiate the bot.
|
||||||
|
2. The bot needs to connect to an XMPP server.
|
||||||
|
3. We have to instruct the bot to start running and processing messages.
|
||||||
|
|
||||||
|
Creating the bot is straightforward, but we can also perform some configuration
|
||||||
|
at this stage. For example, let's say we want our bot to support `service discovery
|
||||||
|
<http://xmpp.org/extensions/xep-0030.html>`_ and `pings <http://xmpp.org/extensions/xep-0199.html>`_:
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
if __name__ == '__main__':
|
||||||
|
|
||||||
|
# .. option parsing and logging steps from above
|
||||||
|
|
||||||
|
xmpp = EchoBot(opts.jid, opts.password)
|
||||||
|
xmpp.register_plugin('xep_0030') # Service Discovery
|
||||||
|
xmpp.register_plugin('xep_0199') # Ping
|
||||||
|
|
||||||
|
If the ``EchoBot`` class had a hard dependency on a plugin, we could register that plugin in
|
||||||
|
the ``EchoBot.__init__`` method instead.
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
If you are using the OpenFire server, you will need to include an additional
|
||||||
|
configuration step. OpenFire supports a different version of SSL than what
|
||||||
|
most servers and SleekXMPP support.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
import ssl
|
||||||
|
xmpp.ssl_version = ssl.PROTOCOL_SSLv3
|
||||||
|
|
||||||
|
Now we're ready to connect and begin echoing messages. If you have the package
|
||||||
|
``dnspython`` installed, then the :meth:`sleekxmpp.clientxmpp.ClientXMPP` method
|
||||||
|
will perform a DNS query to find the appropriate server to connect to for the
|
||||||
|
given JID. If you do not have ``dnspython``, then SleekXMPP will attempt to
|
||||||
|
connect to the hostname used by the JID, unless an address tuple is supplied
|
||||||
|
to :meth:`sleekxmpp.clientxmpp.ClientXMPP`.
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
if __name__ == '__main__':
|
||||||
|
|
||||||
|
# .. option parsing & echo bot configuration
|
||||||
|
|
||||||
|
if xmpp.connect():
|
||||||
|
xmpp.process(block=True)
|
||||||
|
else:
|
||||||
|
print('Unable to connect')
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
For Google Talk users withouth ``dnspython`` installed, the above code
|
||||||
|
should look like:
|
||||||
|
|
||||||
|
.. code-block:: python
|
||||||
|
|
||||||
|
if __name__ == '__main__':
|
||||||
|
|
||||||
|
# .. option parsing & echo bot configuration
|
||||||
|
|
||||||
|
if xmpp.connect(('talk.google.com', 5222)):
|
||||||
|
xmpp.process(block=True)
|
||||||
|
else:
|
||||||
|
print('Unable to connect')
|
||||||
|
|
||||||
|
To begin responding to messages, you'll see we called :meth:`sleekxmpp.basexmpp.BaseXMPP.process`
|
||||||
|
which will start the event handling, send queue, and XML reader threads. It will also call
|
||||||
|
the :meth:`sleekxmpp.plugins.base.base_plugin.post_init` method on all registered plugins. By
|
||||||
|
passing ``block=True`` to :meth:`sleekxmpp.basexmpp.BaseXMPP.process` we are running the
|
||||||
|
main processing loop in the main thread of execution. The :meth:`sleekxmpp.basexmpp.BaseXMPP.process`
|
||||||
|
call will not return until after SleekXMPP disconnects. If you need to run the client in the background
|
||||||
|
for another program, use ``block=False`` to spawn the processing loop in its own thread.
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
Before 1.0, controlling the blocking behaviour of :meth:`sleekxmpp.basexmpp.BaseXMPP.process` was
|
||||||
|
done via the ``threaded`` argument. This arrangement was a source of confusion because some users
|
||||||
|
interpreted that as controlling whether or not SleekXMPP used threads at all, instead of how
|
||||||
|
the processing loop itself was spawned.
|
||||||
|
|
||||||
|
The statements ``xmpp.process(threaded=False)`` and ``xmpp.process(block=True)`` are equivalent.

The Final Product

|

Here then is what the final result should look like after working through the guide above. The code

You can run the code using:
|
||||||
|
|
||||||
|
.. code-block:: sh
|
||||||
|
|
||||||
|
python echobot.py -d -j echobot@example.com
|
||||||
|
|
||||||
|
which will prompt for the password and then begin echoing messages. To test, open
|
||||||
|
your regular IM client and start a chat with the echo bot. Messages you send to it should
|
||||||
|
be mirrored back to you. Be careful if you are using the same JID for the echo bot that
|
||||||
|
you also have logged in with another IM client. Messages could be routed to your IM client instead
|
||||||
|
of the bot.

SleekXMPP Quickstart
|
|
||||||
====================
|
|

|
|
||||||
.. note::
|
|
||||||
|
|
||||||
If you have any issues working through this quickstart guide
|
|
||||||
or the other tutorials here, please either send a message to the
|
|
||||||
`mailing list <http://groups.google.com/group/sleekxmpp-discussion>`_

or join the chat room at `sleek@conference.jabber.org
|
|
||||||
<xmpp:sleek@conference.jabber.org?join>`_.
|
|
||||||
|
|
||||||
If you have not yet installed SleekXMPP, do so now by either checking out a version
|
|
||||||
from `Github <http://github.com/fritzy/SleekXMPP>`_, or installing it using ``pip``
|
|
||||||
or ``easy_install``.
|
|
||||||
|
|
||||||
.. code-block:: sh
|
|
||||||
|
|
||||||
pip install sleekxmpp # Or: easy_install sleekxmpp
|
|
||||||
|
|
||||||
|
|
||||||
As a basic starting project, we will create an echo bot which will reply to any
|
|
||||||
messages sent to it. We also go through adding some basic command line configuration
|
|
||||||
for enabling or disabling debug log outputs and setting the username and password
|
|
||||||
for the bot.
|
|
||||||
|
|
||||||
For the command line options processing, we will use the built-in ``optparse``
|
|
||||||
module and the ``getpass`` module for reading in passwords.

||||||

|
|
||||||
Overview
|
|
||||||
--------
|
|
||||||
|
|
||||||
To get started, here is a brief outline of the structure that the final project will have:
|
|
||||||
|
|
||||||
.. code-block:: python
|
|
||||||
|
|
||||||
#!/usr/bin/env python
|
|
||||||
# -*- coding: utf-8 -*-
|
|
||||||
|
|
||||||
import sys
|
|
||||||
import logging
|
|
||||||
import getpass
|
|
||||||
from optparse import OptionParser
|
|
||||||
|
|
||||||
import sleekxmpp
|
|
||||||
|
|
||||||
'''Here we will create out echo bot class'''
|
|
||||||
|
|
||||||
if __name__ == '__main__':
|
|
||||||
'''Here we will configure and read command line options'''
|
|
||||||
|
|
||||||
'''Here we will instantiate our echo bot'''
|
|
||||||
|
|
||||||
'''Finally, we connect the bot and start listening for messages'''
|
|
||||||
|
|
||||||
Creating the EchoBot Class
|
|
||||||
--------------------------
|
|
||||||
|
|
||||||
There are three main types of entities within XMPP — servers, components, and
|
|
||||||
clients. Since our echo bot will only be responding to a few people, and won't need
|
|
||||||
to remember thousands of users, we will use a client connection. A client connection
|
|
||||||
is the same type that you use with your standard IM client such as Pidgin or Psi.
|
|
||||||
|
|
||||||
SleekXMPP comes with a :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>` class
|
|
||||||
which we can extend to add our message echoing feature. :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>`
|
|
||||||
requires the parameters ``jid`` and ``password``, so we will let our ``EchoBot`` class accept those
|
|
||||||
as well.
|
|
||||||
|
|
||||||
.. code-block:: python
|
|
||||||
|
|
||||||
class EchoBot(sleekxmpp.ClientXMPP):
|
|
||||||
|
|
||||||
def __init__(self, jid, password):
|
|
||||||
super(EchoBot, self).__init__(jid, password)
|
|
||||||
|
|
||||||
Handling Session Start
|
|
||||||
~~~~~~~~~~~~~~~~~~~~~~
|
|
||||||
The XMPP spec requires clients to broadcast its presence and retrieve its roster (buddy list) once
|
|
||||||
it connects and establishes a session with the XMPP server. Until these two tasks are completed,
|
|
||||||
some servers may not deliver or send messages or presence notifications to the client. So we now
|
|
||||||
need to be sure that we retrieve our roster and send an initial presence once the session has
|
|
||||||
started. To do that, we will register an event handler for the :term:`session_start` event.
|
|
||||||
|
|
||||||
.. code-block:: python
|
|
||||||
|
|
||||||
def __init__(self, jid, password):
|
|
||||||
super(EchoBot, self).__init__(jid, password)
|
|
||||||
|
|
||||||
self.add_event_handler('session_start', self.start)
|
|
||||||
|
|
||||||
|
|
||||||
Since we want the method ``self.start`` to execute when the :term:`session_start` event is triggered,
|
|
||||||
we also need to define the ``self.start`` handler.
|
|
||||||
|
|
||||||
.. code-block:: python
|
|
||||||
|
|
||||||
def start(self, event):
|
|
||||||
self.send_presence()
|
|
||||||
self.get_roster()
|
|
||||||
|
|
||||||
.. warning::
|
|
||||||
|
|
||||||
Not sending an initial presence and retrieving the roster when using a client instance can
|
|
||||||
prevent your program from receiving presence notifications or messages depending on the
|
|
||||||
XMPP server you have chosen.
|
|
||||||
|
|
||||||
Our event handler, like every event handler, accepts a single parameter which typically is the stanza
|
|
||||||
that was received that caused the event. In this case, ``event`` will just be an empty dictionary since
|
|
||||||
there is no associated data.
|
|
||||||
|
|
||||||
Our first task of sending an initial presence is done using :meth:`send_presence <sleekxmpp.basexmpp.BaseXMPP.send_presence>`.
|
|
||||||
Calling :meth:`send_presence <sleekxmpp.basexmpp.BaseXMPP.send_presence>` without any arguments will send the simplest
|
|
||||||
stanza allowed in XMPP:
|
|
||||||
|
|
||||||
.. code-block:: xml
|
|
||||||
|
|
||||||
<presence />
|
|
||||||
|
|
||||||
|
|
||||||
The second requirement is fulfilled using :meth:`get_roster <sleekxmpp.clientxmpp.ClientXMPP.get_roster>`, which
|
|
||||||
will send an IQ stanza requesting the roster to the server and then wait for the response. You may be wondering
|
|
||||||
what :meth:`get_roster <sleekxmpp.clientxmpp.ClientXMPP.get_roster>` returns since we are not saving any return
|
|
||||||
value. The roster data is saved by an internal handler to ``self.roster``, and in the case of a :class:`ClientXMPP
|
|
||||||
<sleekxmpp.clientxmpp.ClientXMPP>` instance to ``self.client_roster``. (The difference between ``self.roster`` and
|
|
||||||
``self.client_roster`` is that ``self.roster`` supports storing roster information for multiple JIDs, which is useful
|
|
||||||
for components, whereas ``self.client_roster`` stores roster data for just the client's JID.)
|
|
||||||
|
|
||||||
It is possible for a timeout to occur while waiting for the server to respond, which can happen if the
|
|
||||||
network is excessively slow or the server is no longer responding. In that case, an :class:`IQTimeout
|
|
||||||
<sleekxmpp.exceptions.IQTimeout>` is raised. Similarly, an :class:`IQError <sleekxmpp.exceptions.IQError>` exception can
|
|
||||||
be raised if the request contained bad data or requested the roster for the wrong user. In either case, you can wrap the
|
|
||||||
``get_roster()`` call in a ``try``/``except`` block to retry the roster retrieval process.
|
|
||||||
|
|
||||||
The XMPP stanzas from the roster retrieval process could look like this:
|
|
||||||
|
|
||||||
.. code-block:: xml
|
|
||||||
|
|
||||||
<iq type="get">
|
|
||||||
<query xmlns="jabber:iq:roster" />
|
|
||||||
</iq>
|
|
||||||
|
|
||||||
<iq type="result" to="echobot@example.com" from="example.com">
|
|
||||||
<query xmlns="jabber:iq:roster">
|
|
||||||
<item jid="friend@example.com" subscription="both" />
|
|
||||||
</query>
|
|
||||||
</iq>
|
|
||||||
|
|
||||||
Responding to Messages
|
|
||||||
~~~~~~~~~~~~~~~~~~~~~~
|
|
||||||
Now that an ``EchoBot`` instance handles :term:`session_start`, we can begin receiving and responding
|
|
||||||
to messages. The :term:`message` event is fired whenever a ``<message />`` stanza is received, including
|
|
||||||
for group chat messages, errors, etc. Properly responding to messages thus requires checking the ``'type'``
|
|
||||||
interface of the message :term:`stanza object`.
