在wcf服务中公开webhttpbinding终结点

我创建了一个WCF服务并公开了三个端点,分别是basichttpbinding、wshttpbinding和webhttpbinding。这是我使用WCF进行的实验的测试服务。但是,每当我使用.svc文件添加服务引用时,我只得到两个(basic和ws)端点。似乎没有第三个端点(webhttpbiding)出于某种原因被公开。

若要重现此问题,请创建一个wcf应用程序项目,删除service1服务,添加名为testservice的新项>wcf服务,并将配置文件更改为以下内容:

<system.serviceModel>
<services>
  <service name="WcfTestService.TestService" behaviorConfiguration="TestServiceBehavior">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost/WcfTestService/TestService.svc"/>
      </baseAddresses>
    </host>
    <endpoint address="basic"
              binding="basicHttpBinding"
              contract="WcfTestService.ITestService" />
    <endpoint address="ws"
              binding="wsHttpBinding"
              contract="WcfTestService.ITestService" />
    <endpoint address="web"
              binding="webHttpBinding"
              contract="WcfTestService.ITestService" />
    <endpoint address="mex"
              binding="mexHttpBinding"
              contract="IMetadataExchange" />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="TestServiceBehavior">
      <serviceMetadata httpGetEnabled="true" />
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="webBehavior">
      <webHttp />
    </behavior>
  </endpointBehaviors>
</behaviors>

以下是itestservice.cs的代码:

[ServiceContract]
public interface ITestService
{
    [OperationContract]
    [WebInvoke]
    Boolean ValidateUser(User user);
}

[DataContract]
public class User
{
    [DataMember(Name = "Name")]
    public String UserName { get; set; }
    [DataMember]
    public String Password { get; set; }
}

对于testservice.svc

public class TestService : ITestService
{
    public bool ValidateUser(User user)
    {
        if (user.UserName == "User" && user.Password == "123")
        {
            return true;
        }
        return false;
    }
}

我尝试了WebInvoke参数和Webget参数的不同组合,但失败了。

有人能告诉我为什么第三个端点没有出现在WSDL文件中吗?
