・XML-RPC日历服务器

import calendar, SimpleXMLRPCServer

#The server object

class Calendar:

    def getMonth(self, year, month):

        return calendar.month(year, month)

    def getYear(self, year):

        return calendar.calendar(year)

calendar_object = Calendar()

server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost", 8888))

server.register_instance(calendar_object)

#Go into the main listener loop

print "Listening on port 8888"

server.serve_forever()

 

・请求日历服务器(Python)

import xmlrpclib

server = xmlrpclib.ServerProxy("http://localhost:8888")

month = server.getMonth(2012, 5)

print month
