Question

我有一个简单的WCF服务，看起来像这样;

[ServiceContract]
public interface IPostService
{
    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml)]
    string CheckAlive();

和...

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class PostService : IPostService
{
    public string CheckAlive()
    {
        return "I'm here.";
    }

在我的MVC Web项目中，我有一个服务引用到我的webservice。

然后我有这样的jQuery代码......

    function callWebMethod() {
        $.support.cors = true;
        $.ajax({
            type: "GET",
            url: "http://localhost:8732/Design_Time_Addresses/MyWebService/Service1/mex/CheckAlive",
            data: "{}",
            contentType: "application/soap+xml; charset=utf-8",

            success: function (msg) {
                alert("data:" + msg.d);
            }, error: function(a,b,c){ alert("error:" + b + ":" + c); }
        });
    }

但是我总是收到“错误请求”错误。我之前从未使用过jQuery的web服务，现在正在挣扎。

嘿，您必须检查WCF服务的端点配置。你可以看到这篇文章的详细信息 - http://www.codeproject.com/Articles/132809/Calling-WCF-Services-using-jQuery

您的postservice课程必须使用[ServiceContract]

进行修饰

namespace MyNamespace
{
    [ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class PostService : IPostService
    {
        public string CheckAlive()
        {
            return "I'm here.";
        }
    }
}

还定义了Global.ascx文件中的路由

protected void Application_Start(object sender, EventArgs e)

    {

      RouteTable.Routes.MapServiceRoute<MyNamespace.PostService >("Service/SomeName");
    }

您可以访问

这样的服务

      url:'http://loalhost:1234/Service/SomeName',

使用jQuery使用WCF服务
