Jabber/XMPP track l r .com Djabot – Python Jabber Bot Good security – TLS support Decentralized – You can run your own Jabber/XMPP server Open – Standards, community, code

What Is a Jabber Bot? track l r .com Djabot – Python Jabber Bot An unmanned Jabber/XMPP client Runs as a program on a computer (ie. as a Linux daemon) Processes incoming messages from other clients

Introducing Djabot track l r .com Djabot – Python Jabber Bot Python Jabber client – TLS support, extensible (bots, auth) Example bots: echo , HTTP-like JSON API djabotd – Django command that implements Djabot and allows you to run bots for your Django based app as a daemon

Djabot – More Information track l r .com Djabot – Python Jabber Bot Requires: PyXMPP, M2Crypto, libxml2-python, dnspython Allows you to provide your own auth callback function to protect your bots Allows you to write as many bots as you like and configure your instance to use them

Djabot – Example Code track l r .com Djabot – Python Jabber Bot #/usr/bin/env python from pyxmpp.all import JID from djabot.djabot import Client if __name__ == '__main__: def auth_check(requestSenderJID): return True # reply to any sender / do not check sender's JID at all BOTS = ['djabot.bots.echo'] c=Client(JID('USERNAME'), 'PASSWORD', 'tls_noverify', BOTS, auth_check) c.connect() c.loop(1)

Djabot – Example Echo Bot Code track l r .com Djabot – Python Jabber Bot from djabot.bots.base import Djabot as Base class Djabot(Base): NAME = 'djabot-echo-bot' def command_echo(self, inputs): return inputs['body'] def status(self, inputs): return 'echoed back: echo %s' % inputs['body']

Djabot commands – inputs track l r .com Djabot – Python Jabber Bot djabot processes received Jabber msg & passes the following dictionary as inputs parameter to any command that you define: inputs = { 'subject': subject, # subject of received msg 'body': body, # body of received msg 'body_json': None, # JSON object ( if possible to load body as JSON) 'jid': sender, # JID of sender }

Jabber/XMPP HTTP-like JSON API track l r .com Djabot – Python Jabber Bot What? request/response JSON API over Jabber/XMPP that mimics HTTP (status code; PUT|POST|GET|DELETE verbs) Why? I prefer “chatting” with my app instead of RESTful HTTP based approach Seriously. Why? Faster & easier implementation of APIs

Core properties of the API protocol track l r .com Djabot – Python Jabber Bot HTTP status code and message property in response transaction property to uniquely identify sent/received messages api property for version namespace of given action property in request

“ GTalk – djabot” example chat about GET track l r .com Djabot – Python Jabber Bot me: {"action": "GET", "api": "1.0", "data": {"id": "123"}, "object": "OBJECT", "transaction": "1234567890"} djabot: {'message': u'GET OBJECT ID 123 OK', 'code': '200', 'data': '{"id": "123", "example_data": "EXAMPLE"}', 'transaction': u'1234567890'}

“ GTalk – djabot” example chat about PUT track l r .com Djabot – Python Jabber Bot me: {"action": "PUT", "api": "1.0", "data": {"id": 123}, "object": "OBJECT", "transaction": "1234567890"} djabot: {'message': u'PUT OBJECT ID 123 OK', 'code': '200', 'transaction': u'1234567890'}

“ GTalk – djabot” example chat about POST track l r .com Djabot – Python Jabber Bot me: {"action": "POST", "api": "1.0", "data": {"id": 123}, "object": "OBJECT", "transaction": "1234567890"} djabot: {'message': u'POST OBJECT ID 123 OK', 'code': '200', 'transaction': u'1234567890'}

“ GTalk – djabot” example chat about DELETE track l r .com Djabot – Python Jabber Bot me: {"action": "DELETE", "api": "1.0", "data": {"id": 123}, "object": "OBJECT", "transaction": "1234567890"} djabot: {'message': u'DELETE OBJECT ID 123 OK', 'code': '200', 'transaction': u'1234567890'}
