基本 HttpBinding 身份验证错误

我是 Web 服务的

新手，我需要通过 C# 桌面应用程序的wsHttpsBinding和basicHttpBinding实现对现有 Web 服务的basicHttpBinding。当我尝试将服务与桌面应用程序一起使用时，出现以下错误：

HTTP 请求被客户端身份验证方案"匿名"禁止。

Web 服务上包含basicHttpBinding和wsHttpsBinding的 web.config 文件如下所示：

<system.serviceModel>
<diagnostics>
  <messageLogging logEntireMessage="true" logMalformedMessages="true"
    logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true"
    maxMessagesToLog="25000">

    <host>
      <baseAddresses>
        <add baseAddress="https://10.50.1.85:1125/HIBridge/HIBridgeService.svc" />
      </baseAddresses>
    </host>
  </service>
</services>

用户名身份验证如下所示：

namespace HIBridgeLib.HIBridgeService.Security
{
  public class MessageSecurityValidator : UserNamePasswordValidator
  {
     private const string USERNAME = "username";
     private const string PASSWORD = "password";
     public override void Validate(string userName, string password)
     {
        if (userName == null || password == null)
        {
            throw new ArgumentNullException();
        }
        if (USERNAME.Equals(userName) && PASSWORD.Equals(password))
        { 
        }
        else
        {    
            throw new FaultException("Invalid Message Security Credentials");
        }
    }
  }
}

我的桌面应用程序代码如下所示以使用 Web 服务：

ChannelFactory<HIBridgeLib.HIBridgeService.IHIBridgeService> myChannelFactory = null;
HIBridgeLib.HIBridgeService.IHIBridgeService HIBridgeService = null;
System.ServiceModel.BasicHttpBinding basicHTTPBinding = new System.ServiceModel.BasicHttpBinding();
basicHTTPBinding.Name = "HIBridge_BasicBinding";
basicHTTPBinding.OpenTimeout = TimeSpan.FromMinutes(1);
basicHTTPBinding.CloseTimeout = TimeSpan.FromMinutes(1);
basicHTTPBinding.SendTimeout = TimeSpan.FromMinutes(1);
basicHTTPBinding.ReceiveTimeout = TimeSpan.FromMinutes(10);
basicHTTPBinding.BypassProxyOnLocal = false;                
basicHTTPBinding.HostNameComparisonMode = System.ServiceModel.HostNameComparisonMode.StrongWildcard;
basicHTTPBinding.MaxBufferPoolSize = 2147483647;
basicHTTPBinding.MaxReceivedMessageSize = 2147483647;
basicHTTPBinding.MessageEncoding = System.ServiceModel.WSMessageEncoding.Text;
basicHTTPBinding.TextEncoding = Encoding.UTF8;
basicHTTPBinding.UseDefaultWebProxy = true;
basicHTTPBinding.AllowCookies = false;
basicHTTPBinding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportWithMessageCredential;
basicHTTPBinding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Certificate;
basicHTTPBinding.Security.Transport.ProxyCredentialType = System.ServiceModel.HttpProxyCredentialType.None;
basicHTTPBinding.Security.Transport.Realm = "";
System.ServiceModel.EndpointAddress endpointAddress = null;
if (LocalMedCart.CartProfile.ConsoleHostname.Contains("/HIBridge/HIBridgeService.svc"))
      endpointAddress = new System.ServiceModel.EndpointAddress(LocalMedCart.CartProfile.ConsoleHostname + "/basic");
else
      endpointAddress = new System.ServiceModel.EndpointAddress(string.Format("https://{0}:{1}/HIBridge/HIBridgeService.svc/basic", LocalMedCart.CartProfile.ConsoleHostname, LocalMedCart.CartProfile.CommunicationPort));
HIBridgeLib.HIBridgeService.Security.PermissiveCertificatePolicy.Enact(string.Format("CN={0}", LocalMedCart.CertificateName));
myChannelFactory = new ChannelFactory<HIBridgeLib.HIBridgeService.IHIBridgeService>(basicHTTPBinding, endpointAddress);
myChannelFactory.Credentials.UserName.UserName = "username";
HIBridgeService = myChannelFactory.CreateChannel();
//do something
((IClientChannel)HIBridgeService).Close();
myChannelFactory.Close();

导致错误的原因是什么？
