我有一个带有 Net.Tcp 绑定的 WCF 服务，我的服务器配置是

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/>
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom"
                customUserNamePasswordValidatorType="Service.PlainUserNameValidator, Service" />
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Service.TestService">
        <endpoint address="" binding="netTcpBinding" contract="Service.ITestService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:8732/Service/TestService/" />
            <add baseAddress="http://localhost:8001/service/TestServiceMex/" />
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
</configuration>

在我打开的配置中customUserNamePasswordValidatorType。启动主机的代码是

class Program
{
    static void Main(string[] args)
    {
        using (ServiceHost host = new ServiceHost(typeof(TestService)))
        {
            host.Open();
            Console.WriteLine("The service is ready.");
            Console.WriteLine(String.Format("Metadata is at {0}?WSDL", host.Description.Endpoints[0].Address));
            Console.WriteLine();
            Console.WriteLine("Press <ENTER> to terminate service.");
            Console.WriteLine();
            Console.ReadLine();
        }
    }
}

我在配置文件中注册的自定义用户名验证器类是

namespace Service
{
    using System;
    using System.IdentityModel.Selectors;

    public class PlainUserNameValidator : UserNamePasswordValidator
    {
        public override void Validate(string userName, string password)
        {
            Console.WriteLine("Requesting username {0} and password {1}.", userName, password);
        }
    }
}

然而，当客户端调用时，验证器似乎永远不会触发。

我需要注意什么特殊技巧才能启用customUserNamePasswordValidatorType绑定Net.Tcp？

两点：

您还没有包含证书，您应该这样做以确保客户端凭据的完整性，如果需要，请设置一个临时证书并将其添加到您的服务凭据中。

<serviceCertificate 
          findValue="localhost" 
            x509FindType="FindBySubjectName" 
            storeLocation="CurrentUser" 
            storeName="My" />

您还没有指定任何安全性 - 为此，客户端和服务端点都需要在其绑定上启用用户名和密码身份验证模式

<netTcpBinding>
  <binding name="tcpWithMessageSecurity">
    <security mode="Message" >
      <message clientCredentialType="UserName"/>
    </security>
  </binding> 
</netTcpBinding>

然后

<endpoint address="" binding="tcpWithMessageSecurity" contract="Service.ITestService">

然后，命名您的行为并将其添加到上面的行中。
