# Patchless XMLRPC Service for Django # Kind of hacky, and stolen from Crast on irc.freenode.net:#django # Self documents as well, so if you call it from outside of an XML-RPC Client # it tells you about itself and its methods # # Brendan W. McAdams <email@example.com> # SimpleXMLRPCDispatcher lets us register xml-rpc calls w/o # running a full XMLRPC Server. It's up to us to dispatch data from SimpleXMLRPCServer import SimpleXMLRPCDispatcher from django.http import HttpResponse # Create a Dispatcher; this handles the calls and translates info to function maps #dispatcher = SimpleXMLRPCDispatcher() # Python 2.4 dispatcher = SimpleXMLRPCDispatcher(allow_none=False, encoding=None) # Python 2.5 def rpc_handler(request): """ the actual handler: if you setup your urls.py properly, all calls to the xml-rpc service should be routed through here. If post data is defined, it assumes it's XML-RPC and tries to process as such Empty post assumes you're viewing from a browser and tells you about the service. """ if len(request.POST): response = HttpResponse(mimetype="application/xml") response.write(dispatcher._marshaled_dispatch(request.raw_post_data)) else: response = HttpResponse() response.write("<b>This is an XML-RPC Service.</b><br>") response.write("You need to invoke it using an XML-RPC Client!<br>") response.write("The following methods are available:<ul>") methods = dispatcher.system_listMethods() for method in methods: # right now, my version of SimpleXMLRPCDispatcher always # returns "signatures not supported"... :( # but, in an ideal world it will tell users what args are expected sig = dispatcher.system_methodSignature(method) # this just reads your docblock, so fill it in! help = dispatcher.system_methodHelp(method) response.write("<li><b>%s</b>: [%s] %s" % (method, sig, help)) response.write("</ul>") response.write('<a href="http://www.djangoproject.com/"> <img src="http://media.djangoproject.com/img/badges/djangomade124x25_grey.gif" border="0" alt="Made with Django." title="Made with Django."></a>') response['Content-length'] = str(len(response.content)) return response def multiply(a, b): """ Multiplication is fun! Takes two arguments, which are multiplied together. Returns the result of the multiplication! """ return a*b # you have to manually register all functions that are xml-rpc-able with the dispatcher # the dispatcher then maps the args down. # The first argument is the actual method, the second is what to call it from the XML-RPC side... dispatcher.register_function(multiply, 'multiply')
You can pretty much write a standard python function in there, just be sure to register it with the dispatcher when you're done.
Here's a quick and dirty client example for testing:
import sys import xmlrpclib rpc_srv = xmlrpclib.ServerProxy("http://localhost:8000/xml_rpc_srv/") result = rpc_srv.multiply( int(sys.argv), int(sys.argv)) print "%d * %d = %d" % (sys.argv, sys.argv, result)
Based on experience, I do recommend that you use Dictionaries for your args rather than long args, but I think that's personal preference (It allows named arguments, eliminates 'out of order' argument issues and it makes the code more self-documenting).

I wrote up a modified version of the XML-RPC view that uses a template for documentation. -- Adam Blinkinsop
I've taken the basics of the SimpleXMLRPCDispatcher above and have turned it into a distributable Django app, django_xmlrpc. -- Graham Binns
Testing your XML-RPC views using the Django test client
I wrote up a small how-to on how to test your XML-RPC views using the Django test client as an XML-RPC transport: http://www.technobabble.dk/2008/apr/02/xml-rpc-dispatching-through-django-test-client/
-- Christian Joergensen
Using the SimpleXMLRPCDispatcher above and integrating it with a JSONRPCDispatcher, I created a Django application that can handle both XMLRPC and JSONRPC requests. It uses a customizable Django template for self-documentation.
