XML和JSON的WCF WebHttp服务根据端点地址选择序列化程序

Question

我正在尝试制作WCF RESTful网络服务，该服务将同时返回XML和JSON。问题是它有效但XML序列化忽略了XML属性。

正如您在端点配置中看到的，我有两个地址，如xml和json。

所以我像 -

那样访问网址

XML -

http://localhost:59310/TestService.svc/xml/GetResponse

JSON -

http://localhost:59310/TestService.svc/json/GetResponse

现在，我希望在访问DataContractFormat网址时使用JSON，并使用XmlSerializerFormat获取XML网址。我怎样才能做到这一点。请帮忙。

这是具有XML属性的响应类。

namespace WCFMultiFormatTest
{
    [XmlRoot(ElementName = "RESPONSE")]
    public class Response
    {
        [XmlAttribute(AttributeName = "MESSAGE")]
        public string Message { get; set; }
    }

    [XmlRoot(ElementName = "TEST")]
    public class Root
    {
        [XmlElement(ElementName = "RESPONSE")]
        public List<Response> Response { get; set; }
    }
}

这是服务实现类（svc）。

namespace WCFMultiFormatTest
{
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Multiple)]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class TestService : ITestService
    {
        public Root GetResponse()
        {
            Root r = new Root();

            r.Response = new List<Response>();

            Response r1 = new Response()
            {
                Message = "Hello"
            };

            Response r2 = new Response()
            {
                Message = "World"
            };

            r.Response.Add(r1);
            r.Response.Add(r2);

            return r;
        }
    }
}

这是服务合约界面。

namespace WCFMultiFormatTest
{
    [ServiceContract]
    public interface ITestService
    {
        [OperationContract]        
        [WebInvoke(Method = "GET", UriTemplate = "/GetResponse")]
        Root GetResponse();
    }
}

这是web.config中的服务配置。
