A common use case for SleekXMPP is to send one-off messages from -time to time. +time to time. For example, one use case could be sending out a notice when +a shell script finishes a task. + +We will create our one-shot bot based on the pattern explained in :ref:`echobot`. To +start, we create a client class based on :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>` and +register a handler for the :term:`session_start` event. We will also accept parameters +for the JID that will receive our message, and the string content of the message. + +.. code-block:: python + + import sleekxmpp + + + class SendMsgBot(sleekxmpp.ClientXMPP): + + def __init__(self, jid, password, recipient, msg): + super(SendMsgBot, self).__init__(jid, password) + + self.recipient = recipient + self.msg = msg + + self.add_event_handler('session_start', self.start) + + def start(self, event): + self.send_presence() + self.get_roster() + +Note that as in :ref:`echobot`, we need to include send an initial presence and request +the roster.

If we were to call +:meth:`disconnect <sleekxmpp.xmlstream.XMLStream.disconnect>` without any parameters, then it is possible +for the client to disconnect before the send queue is processed and the message is actually +sent on the wire. To ensure that our message is processed, we use +:meth:`disconnect(wait=True) <sleekxmpp.xmlstream.XMLStream.disconnect>`. + +.. code-block:: python + + def start(self, event): + self.send_presence() + self.get_roster() + + self.send_message(mto=self.recipient, mbody=self.msg) + + self.disconnect(wait=True) + +.. warning:: + + If you happen to be adding stanzas to the send queue faster than the send thread + can process them, then :meth:`disconnect(wait=True) <sleekxmpp.xmlstream.XMLStream.disconnect>` + will block and not disconnect. + +Final Product +------------- + +.. compound:: + + The final step is to create a small runner script for initialising our ``SendMsgBot`` class and adding some + basic configuration options. By following the basic boilerplate pattern in :ref:`echobot`, we arrive + at the code below. To experiment with this example, you can use: + + .. code-block:: sh + + python send_client.py -d -j oneshot@example.com -t someone@example.net -m "This is a message" + + which will prompt for the password and then log in, send your message, and then disconnect. To test, open + your regular IM client with the account you wish to send messages to. When you run the ``send_client.py`` + example and instruct it to send your IM client account a message, you should receive the message you + gave. If the two JIDs you use also have a mutual presence subscription (they're on each other's buddy lists) + then you will also see the ``SendMsgBot`` client come online and then go offline. + +.. include:: ../../examples/send_client.py + :literal: |
