我在 GAE (Java) 宽度 libjsonrpc 和客户端 (C#) 宽度 lib jayrock 上有 JSON-RPC 服务器。当我调用服务器时，我有这个 JSONExeption：
服务器正在我的站点上运行

我的错误在哪里？
这是我的 src（客户端）：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Jayrock.JsonRpc;
using System.Collections;
using Jayrock.Json;
using System.Net;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
JsonRpcClient1 client = new JsonRpcClient1();
client.RequestEncoding = Encoding.UTF8;
client.Url = "http://localhost:8888/jsonrpc";
MessageBox.Show(client.Invoke("test").ToString());
}
}
class JsonRpcClient1 : Jayrock.JsonRpc.JsonRpcClient
{
protected override WebRequest GetWebRequest(Uri uri)
{
var request = (HttpWebRequest)base.GetWebRequest(uri);
request.ServicePoint.Expect100Continue = false;
request.ContentType = "text/json";
return request;
}
}
}
服务器端：
public class CalcService extends BasicRPCService {
public PGPPdata calc() {
PGPPdata data = new PGPPdata();
data.setD1(2.0d);
data.setD2(3.0d);
data.setD(2.0d + 3.0d);
return data;
}
public String test() {
return "Ok";
}
}
