  • XML-RPC

    v23 v24  
    1 = XML-RPC =
    2 
    3 NOTE: All credit for this code goes to Crast in irc.freenode.net:#django...
    4 
    5 This uses SimpleXMLRPCDispatcher which is part of the standard Python lib in 2.4 (And possibly earlier versions).
    6 
    7 
    8 In discussing ways of handling XML-RPC for Django, I realised I really needed a way to do it without patching Django's code.  Crast in #django came up with a great solution, which I have modified and tweaked a bit.
    9 
    10 I've included it here.  Feel free to fiddle with it and make it your own ... All this code is '''post-mr'''
    11 
    12 Any crappy & garbage code is completely mine; I'm still learning Python so bear with me.  The hacks I added for self-documentation output are just that; any improvements to them would probably be a good thing.
    13 
    14 First, setup your urls.py to map an XML-RPC service:
    15 
    16 
    17 {{{
    18 #!python
    19 urlpatterns = patterns('',
    20     # XML-RPC
    21      (r'^xml_rpc_srv/', 'yourproject.yourapp.xmlrpc.rpc_handler'),
    22 )
    23 }}}
    24 
    25 
    26 Then, in the appropriate place, create a file called xmlrpc.py
    27 
    28 
    29 {{{
    30 #!python
    31 # Patchless XMLRPC Service for Django
    32 # Kind of hacky, and stolen from Crast on irc.freenode.net:#django
    33 # Self documents as well, so if you call it from outside of an XML-RPC Client
    34 # it tells you about itself and its methods
    35 #
    36 # Brendan W. McAdams <brendan.mcadams@thewintergrp.com>
    37 
    38 # SimpleXMLRPCDispatcher lets us register xml-rpc calls w/o
    39 # running a full XMLRPC Server.  It's up to us to dispatch data
    40 
    41 from SimpleXMLRPCServer import SimpleXMLRPCDispatcher
    42 from django.http import HttpResponse
    43 
    44 # Create a Dispatcher; this handles the calls and translates info to function maps
    45 #dispatcher = SimpleXMLRPCDispatcher() # Python 2.4
    46 dispatcher = SimpleXMLRPCDispatcher(allow_none=False, encoding=None) # Python 2.5
    47 
    48  
    49 
    50 def rpc_handler(request):
    51         """
    52         the actual handler:
    53         if you setup your urls.py properly, all calls to the xml-rpc service
    54         should be routed through here.
    55         If post data is defined, it assumes it's XML-RPC and tries to process as such
    56         Empty post assumes you're viewing from a browser and tells you about the service.
    57         """
    58 
    59         response = HttpResponse()
    60         if len(request.POST):
    61                 response.write(dispatcher._marshaled_dispatch(request.raw_post_data))
    62         else:
    63                 response.write("<b>This is an XML-RPC Service.</b><br>")
    64                 response.write("You need to invoke it using an XML-RPC Client!<br>")
    65                 response.write("The following methods are available:<ul>")
    66                 methods = dispatcher.system_listMethods()
    67 
    68                 for method in methods:
    69                         # right now, my version of SimpleXMLRPCDispatcher always
    70                         # returns "signatures not supported"... :(
    71                         # but, in an ideal world it will tell users what args are expected
    72                         sig = dispatcher.system_methodSignature(method)
    73 
    74                         # this just reads your docblock, so fill it in!
    75                         help =  dispatcher.system_methodHelp(method)
    76 
    77                         response.write("<li><b>%s</b>: [%s] %s" % (method, sig, help))
    78 
    79                 response.write("</ul>")
    80                 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>')
    81 
    82         response['Content-length'] = str(len(response.content))
    83         return response
    84 
    85 def multiply(a, b):
    86         """
    87         Multiplication is fun!
    88         Takes two arguments, which are multiplied together.
    89         Returns the result of the multiplication!
    90         """
    91         return a*b
    92 
    93 # you have to manually register all functions that are xml-rpc-able with the dispatcher
    94 # the dispatcher then maps the args down.
    95 # The first argument is the actual method, the second is what to call it from the XML-RPC side...
    96 dispatcher.register_function(multiply, 'multiply')
    97 }}}
    98 
    99 That's it!
    100 
    101 You can pretty much write a standard python function in there, just be sure to register it with the dispatcher when you're done. 
    102 
    103 Here's a quick and dirty client example for testing:
    104 
    105 {{{
    106 #!python
    107 import sys
    108 import xmlrpclib
    109 rpc_srv = xmlrpclib.ServerProxy("http://localhost:8000/xml_rpc_srv/")
    110 result = rpc_srv.multiply( int(sys.argv[1]), int(sys.argv[2]))
    111 print "%d * %d = %d" % (sys.argv[1], sys.argv[2], result)
    112 }}}
    113 
    114 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).
    115 
    116 Have fun!
