How to do XMLRPC with CherryPy

Question

Server (CherryPy 3.2.0):

import cherrypy

class XMLRPCServer(cherrypy._cptools.XMLRPCController):
    def index(self):
        return 'index'
    index.exposed = True

if __name__ =='__main__':
    cherrypy.config.update({
        'server.thread_pool': 1,
        'request.dispatch': cherrypy.dispatch.XMLRPCDispatcher,
        'tools.xmlrpc.on': True,
        'tools.xmlrpc.allow_none': 0, 
    })
    cherrypy.quickstart(XMLRPCServer())

Client (Python 2.7.1):

import xmlrpclib
svc = xmlrpclib.ServerProxy('http://127.0.0.1:8080')
r = svc.index()

Error:

Traceback (most recent call last):

How do you enable xml-rpc in CherryPy, I've googled and read the docs but still stuck.

Answer 1

Here's relavant quote from XMLRPCController documentation:

The XMLRPCDispatcher strips any /RPC2 prefix; if you aren’t using /RPC2 in your URL’s, you can safely skip turning on the XMLRPCDispatcher.

The following works fine. Also pay attention to separating global and application configuration, as you've mixed them up.

sever.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-


import cherrypy


config = {
  'global' : {
    'server.socket_host' : '127.0.0.1',
    'server.socket_port' : 8080,
    'server.thread_pool' : 8
  },
  '/' : {
    'tools.xmlrpc.allow_none' : True
  }
}


class Api(cherrypy._cptools.XMLRPCController):

  @cherrypy.expose
  def mul(self, a, b):
    return a * b


if __name__ == '__main__':
  cherrypy.quickstart(Api(), '/api', config)

client.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-


import xmlrpclib


rpc = xmlrpclib.ServerProxy('http://localhost:8080/api')
print rpc.mul(2, 6)
