从jQuery调用一个简单的WCF服务

我有一个非常简单的WCF服务叫做pilltrkr.svc.我试图通过以下代码从jQuery调用此服务：

var jsondata = JSON.stringify();
    $.ajax({
        type: "POST",async: false,url: './pilltrakr.svc/DoWork/',contentType: "application/json; charset=utf-8",data: jsondata,dataType: "json",success: function (msg) {
            alert(msg);
        },error: function (XMLHttpRequest,textStatus,errorThrown) {
            //                        alert(XMLHttpRequest.status);
            //                        alert(XMLHttpRequest.responseText);
        }
    });

我在本地做这个(所以使用localhost). DoWork只返回一个字符串.当我调用此函数时,我得到一个http：// localhost：57400 / pilltrakr / pilltrakr.svc / DoWork / 404 Not Found

如何调用我的WCF服务？我尝试了几种不同的变体(经过研究).我能够使用代码隐藏方法(客户端)来调用此服务.我确信这是一件非常容易的事情.请指教.

似乎Stack上的每个帖子都包含了服务的接口和实际类,所以我也把它们放在这里,以防万一我有些遗漏：

接口：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.Text;
using System.Web;

namespace serviceContract
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "Ipilltrakr" in both code and config file together.
    [ServiceContract]
    public interface Ipilltrakr
    {
        [OperationContract]
        [WebGet(ResponseFormat = Webmessageformat.Json,BodyStyle = WebMessageBodyStyle.Bare)]
        string DoWork();

        [OperationContract]
        [WebGet(ResponseFormat = Webmessageformat.Json,BodyStyle = WebMessageBodyStyle.Bare)]
        int addUser(string userName,string userPhone,string userEmail,string userPwd,string acctType);
    }
}

类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using pillBoxObjects;

using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;

namespace serviceContract
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "pilltrakr" in code,svc and config file together.
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.required)]
    public class pilltrakr : Ipilltrakr
    {


        string Ipilltrakr.DoWork()
        {
            return "got here";
        }


        int Ipilltrakr.addUser(string userName,string acctType)
        {
            userAccount ua = new userAccount();
            int uId;

            ua.userName = userName;
            ua.userPhone = userPhone;
            ua.userEmail = userEmail;
            ua.userPwd = userPwd;
            ua.userCreateDate = DateTime.Now;
            ua.userAccountType = acctType;

            uId = ua.add();

            return uId;
        }
    }
}

解决方法

可能有点晚了,但几年前我写了一些关于从jQuery调用WCF的博客文章.这也包括故障处理 – 许多文章都忽略了这一点.

Part one和Part two.
