ASP.NET交互Rest服务接口（Jquery的Get与Post方式）

本文将通过一个简单的实例,介绍如何创建一个Rest服务接口,以及通过JQUERY去对它进行调用;主要采取两种方式分别为Get跟Post;其中将通过Post提交简单类型(Sring)以及复杂类型(自定义实现UserModel)与Rest服务进行交互;

一 Rest服务创建

其中Web客户端(ClintWeb)不对其它层的引用,只通过Rest部署后的服务进行效互;

1:实体层(Model)

using System.Runtime.Serialization;

namespace Model
{
    [DataContract]
    public class UserModel
    {
        [DataMember]
        public int ID { get; set; }

        [DataMember]
        public string UserName { get; set; }

        [DataMember]
        public string PassWord { get; set; }

        [DataMember]
        public int Age { get; set; }

        public override string ToString()
        {
            return string.Format("ID：{0};姓名: {1};年龄：{2};密码：{3}",ID, UserName, Age, PassWord);
        }
    }
}

此处要注意[DataContract],[DataMember]在命名空间using System.Runtime.Serialization下面;

 
2:接口层(IServiceInterface)

using System.ServiceModel.Web;
using System.ServiceModel;
using Model;
namespace IServiceInterface
{
    [ServiceContract]
    public interface IUser
    {
        [WebGet(UriTemplate = "/{ID}", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        UserModel GetUserFromID(string ID);

        [WebGet(UriTemplate = "All", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
         BodyStyle = WebMessageBodyStyle.Bare)]
        List<UserModel> GetAllUser();

        [WebInvoke(UriTemplate = "/User/UserName", Method = "POST", RequestFormat = WebMessageFormat.Json,ResponseFormat=WebMessageFormat.Json,
         BodyStyle = WebMessageBodyStyle.WrappedRequest)]
        String GetUserName(string Name);

        [WebInvoke(UriTemplate = "/User/Post", Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
         BodyStyle = WebMessageBodyStyle.WrappedRequest)]
        string UpdateUser(UserModel model);
    }
}

3:逻辑层(ServiceBll)

using IServiceInterface;
using Model;
namespace ServiceBll
{
    public class UserBll:IUser
    {
        public static List<UserModel> GetUserList()
        {
            List<UserModel> list = new List<UserModel>()
            {
                new UserModel(){ID=1,UserName="踏浪帅",PassWord="123456",Age=27},

                new UserModel(){ID=2,UserName="wujunyang",PassWord="345678",Age=30},
                new UserModel(){ID=3,UserName="cnblogs",PassWord="987654",Age=33}
            };
            return list;
        }

        public UserModel GetUserFromID(string ID)
        {
            UserModel item = GetUserList().Where(a => a.ID == int.Parse(ID)).SingleOrDefault();
            if (item != null)
            {
                return item;
            }
            else
            {
                return new UserModel();
            }
        }

        public List<UserModel> GetAllUser()
        {
            return GetUserList();
        }

        public string UpdateUser(UserModel model)
        {
            return model.ToString();
        }

        public String GetUserName(string Name)
        {
            return "您好：" + Name;
        }
    }
}

后面创建的客户端传参数要跟上面各个方法的参数相同，比如：Name,model等

4:Rest服务(RestService)

此处新建一个文本文件把它修改成.svc格式，在其里面写入：

<%@ ServiceHost Language="C#" Debug="true" Service="ServiceBll.UserBll" %>

web.config文件内容：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="webHttp">
          <webHttp helpEnabled="true"/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="MapConfigBehavior">
          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false 并删除上面的元数据终结点 -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBindConfig" receiveTimeout="00:30:00" sendTimeout="00:30:00" maxReceivedMessageSize="104857600">
          <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647"/>
          <security mode="None"></security>
        </binding>
      </webHttpBinding>
    </bindings>
    <services>
      <service name="ServiceBll.UserBll" behaviorConfiguration="MapConfigBehavior">
        <endpoint binding="webHttpBinding" contract="IServiceInterface.IUser" bindingConfiguration="webHttpBindConfig" behaviorConfiguration="webHttp"/>
      </service>
    </services>
  </system.serviceModel>
</configuration>
