WCF - 找不到webHttpBinding端点

Question

我是WCF的新人。我已成功在VS 2015中设置了一个工作项目。在此，我有两个Services Contracts，每个都有一个Operation Contract。对于我需要的复合类，我也有一个DataContract。我已将wcf解决方案设置为IIS，端口8000上的网站。

我的真正问题是：如果对应于这两个合同的两个端点都在basicHttpBinding中，当我点击F5时它们都出现在WCF客户端中，它们都可以被调用并给出预期的结果，并且它们两者都可以被测试控制台解决方案使用。

但是，只要我将第二个切换到webHttpBinding并添加webhttp behaviorConfiguration（以便能够使用json数据），此端点就会停止出现在WCF客户端中，当然不能再调用，我收到一个未找到的＆＃34;端点＆＃34;从我的测试解决方案。在这种情况下，我使用HttpWebRequest尝试访问端点;它在错误的html消息中，我可以读取端点未找到。

也许我在这里遗漏了一些明显的东西。

以下是代码：

Service.cs

    namespace WcfService2
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class DbQuery : IDbQuery, IDbQueryJason
    {
        public string GetDescriptions(string ParametersString)
        {
            return "received " + ParametersString;
        }
        public string GetDescriptionsInJson(string ParametersString)
        {
            return "received2 " + ParametersString;
        }
    }
}

Iservice.cs：

    namespace WcfService2
    {
        [ServiceContract]
        public interface IDbQuery
        {
            [OperationContract]
            [WebInvoke(UriTemplate = "/getdescriptions",
            BodyStyle = WebMessageBodyStyle.Wrapped)]
            List<Description> GetDescriptions(string Parameters);
        }
        [ServiceContract]
        public interface IDbQueryJason
        {
            [OperationContract]
            [WebInvoke(UriTemplate = "/getdescriptionsinjson",
            BodyStyle = WebMessageBodyStyle.Wrapped)]
            string GetDescriptionsInJson(string Parameters);
        }
        [DataContract]
        public class Description
        {
            [DataMember]
            public string IDInfo;
            [DataMember]
            public string CatalogInfo;
            [DataMember]
            public string TitleInfo;
            [DataMember]
            public string AuthoringInfo;
            [DataMember]
            public string FormatInfo;
            [DataMember]
            public string DateInfo;
        }
}

测试解决方案摘要：

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://localhost:8000/Service.svc/getdescriptionsinjson");
            req.Method = "POST";
