用 C# 实现一个简单的 Restful Service 供外部调用，大体总结为4点：
- The service contract (the methods it offers).
- How do you know which one to access from the URL given (URL Routing).
- The implementation of the service.
- How you will host the service.
详细的基本步骤如下所示：
1）：工程结构（Class Library Project）
2）： IRestDemoService.cs
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using System.ServiceModel.Web;namespace EricSunRestService{ [ServiceContract(Name = "RestDemoServices")] public interface IRestDemoServices { [OperationContract] [WebGet(UriTemplate = Routing.GetClientRoute, BodyStyle = WebMessageBodyStyle.Bare)] string GetClientNameById(string Id); } public static class Routing { public const string GetClientRoute = "/Client/{id}"; }}
3）：RestDemoService.cs
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using System.ServiceModel.Activation;namespace EricSunRestService{ [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single, IncludeExceptionDetailInFaults = true)] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class RestDemoServices : IRestDemoServices { public string GetClientNameById(string Id) { string ReturnString = "HaHa id is: " + Id; return ReturnString; } }}
4）：Host Service 工程结构 （Console Application）
5）：Program.cs
using System;using System.Collections.Generic;using System.Linq;using System.Text;using EricSunRestService;using System.ServiceModel.Web;namespace EricSunHostService{ class Program { static void Main(string[] args) { RestDemoServices demoServices = new RestDemoServices(); WebServiceHost _serviceHost = new WebServiceHost(demoServices, new Uri("http://localhost:8000/DemoService")); _serviceHost.Open(); Console.ReadKey(); _serviceHost.Close(); } }}
6）：运行Host程序，在浏览器中输入对应Service的Url
