The SimpleXMLRPCServer class is based on SocketServer.TCPServer and provides a means of creating simple, stand alone XML-RPC servers.
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.
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 _dispatch() is returned to the client as the result. If instance does not have a _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 _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.
Changed in version 2.3.5, 2.4.1: allow_dotted_names was added to plug a security hole; prior versions are insecure.
system.methodSignature. New in version 2.3.
('/', '/RPC2'). New in version 2.5.
from SimpleXMLRPCServer import SimpleXMLRPCServer # Create server server = SimpleXMLRPCServer(("localhost", 8000)) 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.Server('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()
