从jQuery调用简单的WCF服务 [英] calling a simple WCF Service from jQuery
问题描述
我有一个非常简单的WCF服务，名为pilltrkr.svc.我正在尝试通过以下代码从jQuery调用此服务:
I have a very simple WCF Service called pilltrkr.svc. I'm trying to call this service from jQuery via the following code:
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);
}
});
我正在本地执行此操作(因此使用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找不到
I am doing this locally (so using localhost). DoWork just returns a string. When I call this function I get a http://localhost:57400/pilltrakr/pilltrakr.svc/DoWork/ 404 Not Found
如何致电WCF服务?我已经尝试了几种不同的变体(在研究之后).我能够使用方法背后的代码(客户端)来调用此服务.我敢肯定这是一件容易的事.请告知.
How do I call my WCF Service? I've tried several different variations (after researching). I was able to call this service using the code behind method (client). I'm sure this is a real easy thing to do. Please advise.

似乎Stack上的每个帖子都包含该服务的接口和实际类，所以我也把它们放在这里，以防万一我丢失了一些东西:
It seems like every post on Stack includes the interface and the actual class for the service, so I am also putting them here, just in case there is something I'm missing:
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);
}
}

我想出了最终如何从jQuery调用我的简单WCF服务的方法.阅读此链接后，我找到了一些源代码:
I figured out how to finally call my simple WCF service from jQuery. I found some source code after reading this link:
http://www.west-wind.com/weblog/posts/2009/Sep/15/Making-jQuery-calls-to-WCFASMX-with-a-ServiceProxy-Client .此链接未提供源，但它是引用此链接的另一页.
http://www.west-wind.com/weblog/posts/2009/Sep/15/Making-jQuery-calls-to-WCFASMX-with-a-ServiceProxy-Client. This link doesn't provide the source but it was another page that referenced this link.
无论如何，我下载了代码，并开始将我的代码与这个正在通过jQuery调用WCF服务的项目进行比较.我发现我的web.config文件太复杂了，所以我大大简化了它.然后我也意识到我的方法不是公开的.因此，我将它们公开，然后再进行一些调整(即删除名称空间)后，页面开始返回我尝试返回的简单字符串.
Anyway, I downloaded the code and started to compare my code versus this working project that was calling a WCF Service via jQuery. What I found was that my web.config file was way too complicated so I shorted that up considerably. Then I also realized that my methods were not public. So I made them public and then after a few more tweaks (i.e. taking out the namespaces) the page started to return the simple string I was trying to return.
<system.serviceModel>
<services>
<service name="pilltrakr" behaviorConfiguration="MyServiceTypeBehaviors">
<endpoint address="" behaviorConfiguration="pilltrakrAspNetAjaxBehavior" binding="webHttpBinding" contract="Ipilltrakr"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors">
