+:mod:`SimpleXMLRPCServer` --- Basic XML-RPC server
+==================================================
+
+.. module:: SimpleXMLRPCServer
+ :synopsis: Basic XML-RPC server implementation.
+.. moduleauthor:: Brian Quinlan <brianq@activestate.com>
+.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
+
+.. note::
+ The :mod:`SimpleXMLRPCServer` module has been merged into
+ :mod:`xmlrpc.server` in Python 3.0. The :term:`2to3` tool will automatically
+ adapt imports when converting your sources to 3.0.
+
+
+.. versionadded:: 2.2
+
+The :mod:`SimpleXMLRPCServer` module provides a basic server framework for
+XML-RPC servers written in Python. Servers can either be free standing, using
+:class:`SimpleXMLRPCServer`, or embedded in a CGI environment, using
+:class:`CGIXMLRPCRequestHandler`.
+
+
+.. class:: SimpleXMLRPCServer(addr[, requestHandler[, logRequests[, allow_none[, encoding]]]])
+
+ Create a new server instance. This class provides methods for registration of
+ functions that can be called by the XML-RPC protocol. The *requestHandler*
+ parameter should be a factory for request handler instances; it defaults to
+ :class:`SimpleXMLRPCRequestHandler`. The *addr* and *requestHandler* parameters
+ are passed to the :class:`SocketServer.TCPServer` constructor. If *logRequests*
+ is true (the default), requests will be logged; setting this parameter to false
+ will turn off logging. The *allow_none* and *encoding* parameters are passed
+ on to :mod:`xmlrpclib` and control the XML-RPC responses that will be returned
+ from the server. The *bind_and_activate* parameter controls whether
+ :meth:`server_bind` and :meth:`server_activate` are called immediately by the
+ constructor; it defaults to true. Setting it to false allows code to manipulate
+ the *allow_reuse_address* class variable before the address is bound.
+
+ .. versionchanged:: 2.5
+ The *allow_none* and *encoding* parameters were added.
+
+ .. versionchanged:: 2.6
+ The *bind_and_activate* parameter was added.
+
+
+.. class:: CGIXMLRPCRequestHandler([allow_none[, encoding]])
+
+ Create a new instance to handle XML-RPC requests in a CGI environment. The
+ *allow_none* and *encoding* parameters are passed on to :mod:`xmlrpclib` and
+ control the XML-RPC responses that will be returned from the server.
+
+ .. versionadded:: 2.3
+
+ .. versionchanged:: 2.5
+ The *allow_none* and *encoding* parameters were added.
+
+
+.. class:: SimpleXMLRPCRequestHandler()
+
+ Create a new request handler instance. This request handler supports ``POST``
+ requests and modifies logging so that the *logRequests* parameter to the
+ :class:`SimpleXMLRPCServer` constructor parameter is honored.
+

+
+SimpleXMLRPCServer Objects
+--------------------------
+
+The :class:`SimpleXMLRPCServer` class is based on
+:class:`SocketServer.TCPServer` and provides a means of creating simple, stand
+alone XML-RPC servers.
+
+
+.. method:: SimpleXMLRPCServer.register_function(function[, name])
+
+ Register a function that can respond to XML-RPC requests. If *name* is given,
+ it will be the method name associated with *function*, otherwise
+ ``function.__name__`` will be used. *name* can be either a normal or Unicode
+ string, and may contain characters not legal in Python identifiers, including
+ the period character.
+
+
+.. method:: SimpleXMLRPCServer.register_instance(instance[, allow_dotted_names])
+
+ Register an object which is used to expose method names which have not been
+ registered using :meth:`register_function`. If *instance* contains a
+ :meth:`_dispatch` method, it is called with the requested method name and the
+ parameters from the request. Its API is ``def _dispatch(self, method, params)``
+ (note that *params* does not represent a variable argument list). If it calls
+ an underlying function to perform its task, that function is called as
+ ``func(*params)``, expanding the parameter list. The return value from
+ :meth:`_dispatch` is returned to the client as the result. If *instance* does
+ not have a :meth:`_dispatch` method, it is searched for an attribute matching
+ the name of the requested method.
+
+ If the optional *allow_dotted_names* argument is true and the instance does not
+ have a :meth:`_dispatch` method, then if the requested method name contains
+ periods, each component of the method name is searched for individually, with
+ the effect that a simple hierarchical search is performed. The value found from
+ this search is then called with the parameters from the request, and the return
+ value is passed back to the client.
+
+ .. warning::
+
+ Enabling the *allow_dotted_names* option 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.
+
+ .. versionchanged:: 2.3.5, 2.4.1
+ *allow_dotted_names* was added to plug a security hole; prior versions are
+ insecure.
+
+
+.. method:: SimpleXMLRPCServer.register_introspection_functions()
+
+ Registers the XML-RPC introspection functions ``system.listMethods``,
+ ``system.methodHelp`` and ``system.methodSignature``.
+
+ .. versionadded:: 2.3
+
+
+.. method:: SimpleXMLRPCServer.register_multicall_functions()
+
+ Registers the XML-RPC multicall function system.multicall.
+
+
+.. attribute:: SimpleXMLRPCRequestHandler.rpc_paths
+
+ An attribute value that must be a tuple listing valid path portions of the URL
+ for receiving XML-RPC requests. Requests posted to other paths will result in a
+ 404 "no such page" HTTP error. If this tuple is empty, all paths will be
+ considered valid. The default value is ``('/', '/RPC2')``.
+
+ .. versionadded:: 2.5

+
+SimpleXMLRPCServer Example
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+Server code::
+
+ from SimpleXMLRPCServer import SimpleXMLRPCServer
+ from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler
+
+ # Restrict to a particular path.
+ class RequestHandler(SimpleXMLRPCRequestHandler):
+ rpc_paths = ('/RPC2',)
+
+ # Create server
+ server = SimpleXMLRPCServer(("localhost", 8000),
+ requestHandler=RequestHandler)
+ server.register_introspection_functions()
+
+ # Register pow() function; this will use the value of
+ # pow.__name__ as the name, which is just 'pow'.
+ server.register_function(pow)
+
+ # Register a function under a different name
+ def adder_function(x,y):
+ return x + y
+ server.register_function(adder_function, 'add')
+
+ # Register an instance; all the methods of the instance are
+ # published as XML-RPC methods (in this case, just 'div').
+ class MyFuncs:
+ def div(self, x, y):
+ return x // y
+
+ server.register_instance(MyFuncs())
+
+ # Run the server's main loop
+ server.serve_forever()
+
+The following client code will call the methods made available by the preceding
+server::
+
+ import xmlrpclib
+
+ s = xmlrpclib.ServerProxy('http://localhost:8000')
+ print s.pow(2,3) # Returns 2**3 = 8
+ print s.add(2,3) # Returns 5
+ print s.div(5,2) # Returns 5//2 = 2
+
+ # Print list of available methods
+ print s.system.listMethods()
+
+
+CGIXMLRPCRequestHandler
+-----------------------
+
+The :class:`CGIXMLRPCRequestHandler` class can be used to handle XML-RPC
+requests sent to Python CGI scripts.
+
+
+.. method:: CGIXMLRPCRequestHandler.register_function(function[, name])
+
+ Register a function that can respond to XML-RPC requests. If *name* is given,
+ it will be the method name associated with function, otherwise
+ *function.__name__* will be used. *name* can be either a normal or Unicode
+ string, and may contain characters not legal in Python identifiers, including
+ the period character.
+
+
+.. method:: CGIXMLRPCRequestHandler.register_instance(instance)
+
+ Register an object which is used to expose method names which have not been
+ registered using :meth:`register_function`. If instance contains a
+ :meth:`_dispatch` method, it is called with the requested method name and the
+ parameters from the request; the return value is returned to the client as the
+ result. If instance does not have a :meth:`_dispatch` method, it is searched
+ for an attribute matching the name of the requested method; if the requested
+ method name contains periods, each component of the method name is searched for
+ individually, with the effect that a simple hierarchical search is performed.
+ The value found from this search is then called with the parameters from the
+ request, and the return value is passed back to the client.
+
+
+.. method:: CGIXMLRPCRequestHandler.register_introspection_functions()
+
+ Register the XML-RPC introspection functions ``system.listMethods``,
+ ``system.methodHelp`` and ``system.methodSignature``.
+
+
+.. method:: CGIXMLRPCRequestHandler.register_multicall_functions()
+
+ Register the XML-RPC multicall function ``system.multicall``.
+
+
+.. method:: CGIXMLRPCRequestHandler.handle_request([request_text = None])
+
+ Handle a XML-RPC request. If *request_text* is given, it should be the POST
+ data provided by the HTTP server, otherwise the contents of stdin will be used.
+
+Example::
+
+ class MyFuncs:
+ def div(self, x, y) : return x // y
+
+
+ handler = CGIXMLRPCRequestHandler()
+ handler.register_function(pow)
+ handler.register_function(lambda x,y: x+y, 'add')
+ handler.register_introspection_functions()
+ handler.register_instance(MyFuncs())
+ handler.handle_request()
+
