不废话了，直奔主题吧

wcf端：

近几年比较流行restful，为了能让ajax调用，同时也为了支持restful风格的uri，在创建一个Ajax-enabled Wcf Service后，必须手动修改svc文件，指定Factory，即：

Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>

注：如果不添加Factory，则wcf将无法用类似http://localhost/helloWorld.svc/Hello/person/name 的restful方式直接访问。

同时还要去掉web.config中的即类似:

          multipleSiteBindingsEnabled="true" />


                  binding="webHttpBinding" contract="ajaxSample.HelloWorld" />

好了，开始写代码，鉴于wcf调用时有GET/POST二种方式，下面把几种常用的情况都写一个示例方法：

复制代码代码如下:

using System.Collections.Generic; 
using System.ServiceModel; 
using System.ServiceModel.Activation; 
using System.ServiceModel.Web; 

namespace ajaxSample 
{ 
    [ServiceContract(Namespace = "http://yjmyzz.cnblogs.com/")] 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class HelloWorld 
    { 

        ///  
        /// 只能Post的Restful方法 
        ///  
        ///  
        ///  
        ///  
        [OperationContract] 
        [WebInvoke(Method = "POST", UriTemplate = "PostRestfulTest/{person}/{welcome}", ResponseFormat = WebMessageFormat.Json)] 
        public List PostRestfulTest(string person,string welcome) 
        { 
            List result = new List(); 

            result.Add("PostRestfulTest -> from server:"); 
            result.Add(person); 
            result.Add(welcome); 
            return result; 
        } 

        ///  
        /// 只能Get的Restful方法 
        ///  
        ///  
        ///  
        ///  
        [OperationContract] 
        [WebInvoke(Method = "GET", UriTemplate = "GETRestfulTest/{person}/{welcome}", ResponseFormat = WebMessageFormat.Json)] 
        public List GETRestfulTest(string person, string welcome) 
        { 
            List result = new List(); 

            result.Add("GETRestfulTest -> from server:"); 
            result.Add(person); 
            result.Add(welcome); 
            return result; 
        } 

        ///  
        /// 即可Get与Post的Restful方法 
        ///  
        ///  
        ///  
        ///  
        [OperationContract] 
        [WebInvoke(Method = "*", UriTemplate = "RestfulTest/{person}/{welcome}", ResponseFormat = WebMessageFormat.Json)] 
        public List RestfulTest(string person, string welcome) 
        { 
            List result = new List(); 

            result.Add("RestfulTest -> from server:"); 
            result.Add(person); 
            result.Add(welcome); 
            return result; 
        } 

  
        ///  
        /// 只能Post的常规方法(注：Post方式，BodyStyle必须设置成WrappedRequest或Wrapped) 
        ///  
        ///  
        ///  
        ///  
        [OperationContract] 
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.WrappedRequest)] 
        public List PostTest(string person, string welcome) 
        { 
            List result = new List(); 

            result.Add("PostRestfulTest -> from server:"); 
            result.Add(person); 
            result.Add(welcome); 
            return result; 
        } 

        ///  
        /// 只能Get的常规方法 
        ///  
        ///  
        ///  
        ///  
        [OperationContract] 
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)] 
        public List GETTest(string person, string welcome) 
        { 
            List result = new List(); 

            result.Add("GETTest -> from server:"); 
            result.Add(person); 
            result.Add(welcome); 
            return result; 
        } 

          

          
    } 
}

jQuery调用代码：

复制代码代码如下:

有时候，WCF暴露的方法中可能需要一些敏感信息做为参数(比如用户名/用户ID之类)，这时如果直接用js来调用wcf，可能会把这部分信息泄漏在客户端，这种场景下，我们也经常用一个服务端的ashx来做中转

TestService.svc

复制代码代码如下:

using System.ServiceModel; 

namespace ashx_jQuery 
{ 
     [ServiceContract] 
    public class TestService  
    { 
         ///  
         /// 获取当前用户指定月份的工资 
         ///  
         ///  
         ///  
         ///  
         [OperationContract] 
        public double GetSalary(int userId,int month) 
        { 
            if (month == 1)//只是演示而已 
            { 
                return 5000; 
            } 
            else 
            { 
                return 1000; 
            } 
        } 
    } 
}

AjaxProcess.ashx

复制代码代码如下:

using System.Web; 

namespace ashx_jQuery 
{ 
    ///  
    /// Summary description for AjaxProcess 
    ///  
    public class AjaxProcess : IHttpHandler 
    { 

        public void ProcessRequest(HttpContext context) 
        { 
            context.Response.ContentType = "text/plain"; 
            string month = context.Request["month"]; 

            TestService wcf = new TestService(); 
            double salary = wcf.GetSalary(GetUserId(), int.Parse(month)); 
            context.Response.Write("{salary:" + salary + "}"); 
        } 

  
        ///  
        /// 获取当前的用户ID 
        ///  
        ///  
        private int GetUserId()  
        { 
            return 1; 
        } 

        public bool IsReusable 
        { 
            get
            { 
                return false; 
            } 
        } 
    } 
}
