XML-RPC C#和Python RPC Server

Question

在我的服务器上，我使用Python的标准示例(带有额外的Hello World方法)，而在客户端，我使用C#中的XML-RPC.NET库。但每次我运行我的客户端时，我都会得到找不到该方法的异常。有没有办法解决这个问题。

谢谢!

Python：

from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler

# Restrict to a particular path.
class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)

# Create server
server = SimpleXMLRPCServer(("", 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')

def HelloWorld():
        return "Hello Henrik"

server.register_function(HelloWorld,'HelloWorld')

# 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()

C#

namespace XMLRPC_Test
{
    [XmlRpcUrl("http://188.40.xxx.xxx:8000")]
    public interface HelloWorld : IXmlRpcProxy
    {
        [XmlRpcMethod]
        String HelloWorld();
    }
    [XmlRpcUrl("http://188.40.xxx.xxx:8000")]
    public interface add : IXmlRpcProxy
    {
        [XmlRpcMethod]
        int add(int x, int y);
    } 
    [XmlRpcUrl("http://188.40.xxx.xxx:8000")]
    public interface listMethods : IXmlRpcProxy
    {
        [XmlRpcMethod("system.listMethods")]  
        String listMethods();
    } 

    class Program
    {
        static void Main(string[] args)
        {
            listMethods proxy = XmlRpcProxyGen.Create<listMethods>();
            Console.WriteLine(proxy.listMethods());
            Console.ReadLine();
        }
    }
}

如果你把声明改成这样行吗？

[XmlRpcUrl("http://188.40.xxx.xxx:8000/RPC2")]

从Python docs

SimpleXMLRPCRequestHandler.rpc_paths

一个属性值，它必须是一个元组，列出了用于接收XML-RPC请求的URL的有效路径部分。发送到其他路径的请求将导致404“没有这样的页面”HTTP错误。如果此元组为空，则所有路径都将被视为有效。默认值为('/'，‘/RPC2’)。
