python rpc twisted 服务端和客户端代码演示

#服务器端代码如下
from twisted.web import xmlrpc, server
class Example(xmlrpc.XMLRPC):
    """
    An example object to be published.
    """
    def xmlrpc_echo(self, x):
        """
        Return all passed args.
        """
        return x
 
    def xmlrpc_add(self, a, b):
        """
        Return sum of arguments.
        """
        return a + b
 
    def xmlrpc_fault(self):
        """
        Raise a Fault indicating that the procedure should not be used.
        """
        raise xmlrpc.Fault(123, "The fault procedure is faulty.")
 
if __name__ == '__main__':
    from twisted.internet import reactor
    r = Example()
    reactor.listenTCP(7080, server.Site(r))
    reactor.run()

客户端
