Python's signature dish xmlrpc

First, Brief introduction

In order to resolve the service that provides RPC in the system 80port. Without affecting the running Web service. People have come up with a way to transfer RPC packets using the HTTP protocol. For HTTP protocols that are almost exclusively for transmitting text. The RPC packet on which to transfer. The easiest way to do this is to encode the RPC packet into textual form-such as an XML file.
XML-RPC (http://www.xml-rpc.com) is an RPC protocol specified by the United States Userland Company. It encodes the RPC information packets into XML and then transmits the packets over HTTP;
Simple to understand:
Defines the data as an XML format. Remote transmission over the HTTP protocol.

Second, the advantages

1. Transmission of complex data.
2. Implement the invocation of the remote object through the encapsulation of the program language.

Iii. XMLRPC application in Python
Server side:

From simplexmlrpcserver import * #import simplexmlrpcrequesthandlerdef div (x, y): return x-yclass math:def _listmetho DS (Self): return [' Add ', ' POW '] def _methodhelp (Self,method): if method = = ' Add ': Return ' Add (2,3) =>5 "elif method = = ' POW ': Return" POW (x,y[,z]) =>number "Else:return" "Def _di           Spatch (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)) # R Egister_introspection_functions:registers the Xml-rpc introspection methods in the system Namespaceserver.register_ Introspection_functions () server.register_function (Div, "div") server.register_function (lambda x,y:x*y, ' multiply ')  Server.register_instance (Math ()) #serve_forever: Handle One request at a time until shutdown. #Polls for shutdown every poll_interval seconds. Ignores#self.timeout.If you need to does periodic tasks, do them in#another thread.server.serve_forever () 

Client

Import xmlrpclibs = Xmlrpclib. Serverproxy (' http://localhost:8000 ') print (S.system.listmethods ()) print (S.pow (2,3)) print (S.add (2,3)) print (S.div (3,2)) Print (s.multiply (4,5))
