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;
            }
        }
    }
}
