WCF RESTful 服务未在 /xml/string uri 上启动 - 404 错误

Question

我在 MVC 应用程序中有一个 WCF 服务，但它没有按我的预期工作。

我的 IService.cs 代码如下：

[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebInvoke(Method = "GET",

        // Set output to XML and the text display to wrap
        ResponseFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "xml/{name}")]
    string XMLData(string name);

    [OperationContract]
    [WebInvoke(Method = "GET",

        // Set output to JSON and the text display to wrap
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "json/{name}")]
    string JSONData(string name);
}

我的 Service.svc 代码是：

    public class Service : IService
{
    #region IService Members

    public string XMLData(string name)
    {
        return "Hello " + name;
    }

    public string JSONData(string name)
    {
        return "Hello " + name;
    }
    #endregion
}

当我转到 localhost/Service.svc 时，我得到了我期望的页面。但是，当我转到 localhost/Service.svc/xml/Tim（或 /json/）时，我收到 404 - resource cannot be found 错误。

我很肯定我的 Web.config 文件也配置正确，但如果有人认为这是问题所在，我可以发布该文件（所有 MVC 内容有点臃肿）。

对造成这种情况的原因有什么想法吗？谢谢！

编辑：这是我的完整 Web.config 文件：

我将与您分享我的配置，因为它背后的服务已经不间断地运行了两年，没有出现任何问题，返回 pox、json 和 soap。我敢打赌这是服务端点配置中的东西。

顺便说一句：我认为您不必在 uri 模板（json/xml）中指定端点行为。这更适用于参数匹配类型的东西，imo。

[OperationContract()]
[WebGet(UriTemplate = "GetData/{aParam1}/{aParam2}")]
MyResponse GetData(string aParam1, string aParam2);
