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. The Doc* classes can be used to create XML-RPC servers that serve pydoc-style documentation in response to HTTP GET requests. This documentation is dynamically generated based on the functions and methods registered with the server. 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 sys functions available through sys.func_name import sys self.sys = sys def _listMethods(self): # implement this method so that system.listMethods # knows to advertise the sys methods return list_public_methods(self) + \ ['sys.' + method for method in list_public_methods(self.sys)] 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 ValueError('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.

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 an 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.

XML-RPC methods are dispatched from the marshalled (XML) data using the _dispatch method and the result is returned as marshalled data.
