简单五步创建一个WCF Rest Service

1、创建一个WCF Service Application

2、创建一个实体对象Student，用作数据传输的载体，下面是Student.cs的内容

using System.Runtime.Serialization;namespace WCFRest{    /// <summary>    /// DataContract 数据契约：服务端和客户端之间要传送的自定义数据类型    /// </summary>    [DataContract]    public class Student    {        /// <summary>        /// 在数据传送过程中，只有成员变量可以被传送而成员方法不可以。        /// 并且只有当成员变量加上DataMember时才可以被序列进行数据传输，        /// 如果不加DataMember，客户端将无法获得该属性的任何信息        /// </summary>        [DataMember]        public int Id { get; set; }        [DataMember]        public string Name { get; set; }    }}

同时我们创建一个类，用来模拟数据库的存储

using System.Collections.Generic;namespace WCFRest{    public class UserList    {        private static readonly UserList _Instance = new UserList();        private UserList() { }        public static UserList Instance        {            get { return _Instance; }        }        public IList<Student> Users        {            get { return _Users; }        }        private IList<Student> _Users = new List<Student>{            new Student {Id = 1, Name = "张三" },            new Student {Id = 2, Name = "李四" },            new Student {Id = 3, Name = "王五" }        };    }}

3、创建服务契约

下面我们在项目添加一个WCF Service

首先修改IStudnetService接口,配置Rest的URL路径

using System.Collections.Generic;using System.ServiceModel;using System.ServiceModel.Web;namespace WCFRest{    [ServiceContract]    public interface IStudentService    {        [OperationContract]        [WebInvoke(Method = "GET",           RequestFormat = WebMessageFormat.Json,           ResponseFormat = WebMessageFormat.Json,           UriTemplate = "GetStudentById/Id={Id}"         )]        Student GetStudentById(string Id);        [OperationContract]        [WebInvoke(Method = "GET",           RequestFormat = WebMessageFormat.Json,           ResponseFormat = WebMessageFormat.Json,           UriTemplate = "GetStudentList"         )]        IList<Student> GetStudentList();    }}

4、修改StudentService类，实现Rest方法

using System.Collections.Generic;namespace WCFRest{    public class StudentService : IStudentService    {                public Student GetStudentById(string Id)        {            return StudentList.Instance.Users[int.Parse(Id)];        }        public IList<Student> GetStudentList()        {            return StudentList.Instance.Users;        }    }}

5、配置Service和Behavior

在Web.Config中配置我们的Rest服务

 <system.serviceModel>    <services>      <service name="WCFRest.StudentService" behaviorConfiguration="serviceBehavior">        <endpoint address="" binding="webHttpBinding" contract="WCFRest.IStudentService"                   behaviorConfiguration="web"></endpoint>      </service>    </services>    <behaviors>      <serviceBehaviors>        <behavior name="serviceBehavior">          <serviceMetadata httpGetEnabled="true"/>          <serviceDebug includeExceptionDetailInFaults="false"/>        </behavior>        <behavior>          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>          <serviceDebug includeExceptionDetailInFaults="false"/>        </behavior>      </serviceBehaviors>      <endpointBehaviors>        <behavior name="web">          <webHttp/>        </behavior>      </endpointBehaviors>    </behaviors>    <protocolMapping>      <add binding="basicHttpsBinding" scheme="https" />    </protocolMapping>    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />  </system.serviceModel>

OK，下面测试一下我们的程序，右击Student.svc文件，选择View In Browser，我们将会看到下面的运行结果

然后我们在url后面加上我们定义的Rest地址就可以访问Rest服务了
