c# - Protobuf 格式的 ServiceStack

Question

我正在尝试在 ServiceStack Web 服务中使用 protobuf 格式(遵循 ServiceStack: REST with ProtoBuf by Steven Hollidge 中的示例。我添加了一个 Winform 应用程序来使用 Web 服务。代码如下。

HelloService.cs

using System.Runtime.Serialization;
using ProtoBuf;
using ServiceStack.Demo.Rest;
using ServiceStack.ServiceHost;
using ServiceStack.ServiceInterface;

namespace ServiceStack.Demo.WebService
{
[DataContract] 
public class Hello
{
    [DataMember(Order = 1)]
    public string Name { get; set; }
}
 [DataContract] 
public class HelloResponse
{
    [DataMember(Order = 1)]
    public string Result { get; set; }
}

 public class HelloService : RestServiceBase<Hello>
{
    public  override object OnGet(Hello request)
    {
        return new HelloResponse { Result = "Hello, " + request.Name };
    }
}
}

Global.asax.cs

using System;
using System.Web;
using Funq;
using ServiceStack.Demo.Rest;
using ServiceStack.Demo.WebService;
using ServiceStack.WebHost.Endpoints;

namespace ServiceStack.Demo
{
public class AppHost : AppHostBase
{
    public AppHost() : base("ServiceStack makes services easy!", typeof (AppHost).Assembly)
    {
        ServiceStack.Plugins.ProtoBuf.AppStart.Start();
    }

    public override void Configure(Container container)
    {
        Routes
          .Add<Hello>("/hello")
          .Add<Hello>("/hello/{Name}");

    }
 }

public class Global : HttpApplication
{
    protected void Application_Start(object sender, EventArgs e)
    {
        new AppHost().Init();
    }
}
}

Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using ServiceStack.ServiceClient;
using ProtoBuf;
using ServiceStack.Plugins.ProtoBuf;
using System.Runtime.Serialization;
using ServiceStack.ServiceClient.Web;

namespace client
{
public partial class Form1 : Form
{
    private ServiceClientBase _client;
    private const string Url = "http://localhost/servicestack.demo/servicestack/hello?format=x-protobuf";
    public Form1()
    {
        InitializeComponent();
    }

    private void Button1Click(object sender, EventArgs e)
    {

        this._client =
            new ProtoBufServiceClient(Url);

        var response = _client.Send<HelloResponse>(new Hello {Name = "ProtoBuf"});
        label1.Text = response.Result;
    }

   
    public class Hello
    {
        public string Name { get; set; }
    }

    
    public class HelloResponse
    {
        public string Result { get; set; }
    }
}
}

我得到 System.InvalidOperationException: Type is not expected, no contract can be inferred: client.Form1+Hello

我做错了什么？请建议......

看起来您的 Hello 类和 HelloResponse 类声明了两次。一次在 HelloService.cs 中，一次作为 Form.cs 中的内部类。从您的 Form.cs 文件中删除重复项应该允许您的 ProtoBufServiceClient 引用正确的类/类型。
