This module can be used to create simple XML-RPC servers
by creating a server and either installing functions, a
class instance, or by extending the SimpleXMLRPCServer
class.
It can also be used to handle XML-RPC requests in a CGI
environment using CGIXMLRPCRequestHandler.
A list of possible usage patterns follows:
1. Install functions:
server = SimpleXMLRPCServer(("localhost", 8000))
server.register_function(pow)
server.register_function(lambda x,y: x+y, 'add')
server.serve_forever()
2. Install an instance:
class MyFuncs:
def __init__(self):
# make all of the string functions available through
# string.func_name
import string
self.string = string
def _listMethods(self):
# implement this method so that system.listMethods
# knows to advertise the strings methods
return list_public_methods(self) + ['string.' + method for method in list_public_methods(self.string)]
def pow(self, x, y): return pow(x, y)
def add(self, x, y) : return x + y
server = SimpleXMLRPCServer(("localhost", 8000))
server.register_introspection_functions()
server.register_instance(MyFuncs())
server.serve_forever()
3. Install an instance with custom dispatch method:
class Math:
def _listMethods(self):
# this method must be present for system.listMethods
# to work
return ['add', 'pow']
def _methodHelp(self, method):
# this method must be present for system.methodHelp
# to work
if method == 'add':
return "add(2,3) => 5"
elif method == 'pow':
return "pow(x, y[, z]) => number"
else:
# By convention, return empty
# string if no help is available
return ""
def _dispatch(self, method, params):
if method == 'pow':
return pow(*params)
elif method == 'add':
return params[0] + params[1]
else:
raise 'bad method'
server = SimpleXMLRPCServer(("localhost", 8000))
server.register_introspection_functions()
server.register_instance(Math())
server.serve_forever()
4. Subclass SimpleXMLRPCServer:
class MathServer(SimpleXMLRPCServer):
def _dispatch(self, method, params):
try:
# We are forcing the 'export_' prefix on methods that are
# callable through XML-RPC to prevent potential security
# problems
func = getattr(self, 'export_' + method)
except AttributeError:
raise Exception('method "%s" is not supported' % method)
else:
return func(*params)
def export_add(self, x, y):
return x + y
server = MathServer(("localhost", 8000))
server.serve_forever()
5. CGI script:
server = CGIXMLRPCRequestHandler()
server.register_function(pow)
server.handle_request()

Resolves a dotted attribute name to an object. Raises
an AttributeError if any attribute in the chain starts with a '_'.
If the optional allow_dotted_names argument is false, dots are not
supported and this function operates similar to getattr(obj, attr).

s Mix-in class that dispatches XML-RPC requests.
This class is used to register XML-RPC method handlers
and then to dispatch them. There should never be any
reason to instantiate this class directly.

Only one instance can be installed at a time.
If the registered instance has a _dispatch method then that
method will be called with the name of the XML-RPC method and
its parameters as a tuple
e.g. instance._dispatch('add',(2,3))
If the registered instance does not have a _dispatch method
then the instance will be searched to find a matching method
and, if found, will be called. Methods beginning with an '_'
are considered private and will not be called by
SimpleXMLRPCServer.
If a registered function matches a XML-RPC request, then it
will be called instead of the registered instance.
If the optional allow_dotted_names argument is true and the
instance does not have a _dispatch method, method names
containing dots are supported and resolved, as long as none of
the name segments start with an '_'.
*** SECURITY WARNING: ***
Enabling the allow_dotted_names options allows intruders
to access your module's global variables and may allow
intruders to execute arbitrary code on your machine. Only
use this option on a secure, closed network.

XML-RPC methods are dispatched from the marshalled (XML) data
using the _dispatch method and the result is returned as
marshalled data. For backwards compatibility, a dispatch
function can be provided as an argument (see comment in
SimpleXMLRPCRequestHandler.do_POST) but overriding the
existing method through subclassing is the prefered means
of changing method dispatch behavior.
