Simple uWSGI + XML-RPC

client.py

import xmlrpclib

s = xmlrpclib.ServerProxy('http://localhost:3040')
print s.pow(2,3)
print s.sum([2,3])
print s.system.listMethods()

commands.sh

# start uwsgi with this app, listening with http on some port
uwsgi --wsgi xmlrpc_server --http :3040
# in another window
python client.py
# output should be 8, 5 and a list of functions

xmlrpc_server.py

from SimpleXMLRPCServer import SimpleXMLRPCDispatcher
dispatch = SimpleXMLRPCDispatcher()
dispatch.register_introspection_functions()
dispatch.register_function(pow)
dispatch.register_function(sum)

def application(environ, start_response):
    if environ["REQUEST_METHOD"] != "POST":
        start_response("500 Error", ())
        return ["Only POST allowed"]

    try:
        length = int(environ.get('CONTENT_LENGTH', None))
    except (TypeError, ValueError):
        length = -1

    request_text = environ["wsgi.input"].read(length)
    response = dispatch._marshaled_dispatch(request_text)

    start_response("200 OK", [("Content-Type", "text/xml"), ("Content-Length", str(len(response)))])
    return response

Very usefull for SimpleJSONRPCServer too from package https://github.com/joshmarshall/jsonrpclib!
Thank you very much, that's what I was looking for.
