我正在尝试使用将 ClientCredentialType 设置为“无”的压缩和消息安全性来实现自定义 WS 绑定。该服务已配置并成功运行。我还设法配置客户端并成功运行它。但是，我需要以编程方式设置客户端，因此当我尝试将客户端配置转换为代码时，我收到错误消息“未为目标“xxx”提供服务证书。在 ClientCredentials 中指定服务证书。我正在使用自动生成的代理客户端，并且我遵循建议来覆盖客户端构造函数并直接在 ClientCredentials 或客户端端点行为中指定服务证书CertificateValidationMode ，但仍然没有运气。

我将不胜感激任何帮助解决这个问题。作为参考，我在下面包含了配置及其代码翻译。

客户端配置：

<system.serviceModel>
 <bindings>
  <customBinding>
    <binding name="customWSBinding" sendTimeout="00:15:00">
      <security authenticationMode="SecureConversation" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
        <secureConversationBootstrap authenticationMode="AnonymousForSslNegotiated" messageSecurityVersion="WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10" />
      </security>
      <gzipMessageEncoding innerMessageEncoding="textMessageEncoding"/>
      <httpTransport hostNameComparisonMode="StrongWildcard" manualAddressing="False"
                      maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647"
                      authenticationScheme="Anonymous" bypassProxyOnLocal="False" realm="" useDefaultWebProxy="True"/>
    </binding>
  </customBinding>
 </bindings>
 <client>
  <endpoint address=""
    binding="customBinding"
    bindingConfiguration="customWSBinding"
    behaviorConfiguration="ClientBehavior"
    contract="IService"
    name="ServiceEndpoint">
    <identity>
      <dns value="contoso.com"/>
    </identity>
  </endpoint>
 </client>
 <behaviors>
  <endpointBehaviors>
    <behavior name="ClientBehavior">
      <clientCredentials>
        <serviceCertificate>
          <authentication certificateValidationMode="None"/>
        </serviceCertificate>
      </clientCredentials>
    </behavior>
  </endpointBehaviors>
 </behaviors>
</system.serviceModel>

等效代码：

SecurityBindingElement securityElement =   SecurityBindingElement.CreateSecureConversationBindingElement(SecurityBindingElement.CreateAnonymousForCertificateBindingElement());
securityElement.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

GZipMessageEncodingBindingElement encodingElement = new GZipMessageEncodingBindingElement();
TextMessageEncodingBindingElement txtMsgBE = new TextMessageEncodingBindingElement();
encodingElement.InnerMessageEncodingBindingElement = txtMsgBE;

HttpTransportBindingElement httpTransportElement = new HttpTransportBindingElement();
httpTransportElement.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
httpTransportElement.ManualAddressing = false;
httpTransportElement.MaxReceivedMessageSize = Int32.MaxValue;
httpTransportElement.MaxBufferSize = Int32.MaxValue;
httpTransportElement.MaxBufferPoolSize = Int32.MaxValue;
httpTransportElement.AuthenticationScheme = AuthenticationSchemes.Anonymous;
httpTransportElement.BypassProxyOnLocal = false;
httpTransportElement.UseDefaultWebProxy = true;

System.ServiceModel.Channels.Binding binding = new CustomBinding(securityElement, encodingElement, httpTransportElement);
binding.SendTimeout = TimeSpan.FromMinutes(15);

EndpointAddress address = new EndpointAddress(new Uri(svcURL),    EndpointIdentity.CreateDnsIdentity("contoso.com"));

ServiceClient svcClient = new ServiceClient(binding, address);

被覆盖的代理客户端：

public ServiceClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress)
:base (binding, remoteAddress)
{
    System.ServiceModel.Description.ClientCredentials cc = new System.ServiceModel.Description.ClientCredentials();
    cc.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;

    base.Endpoint.Behaviors.RemoveAt(1);
    base.Endpoint.Behaviors.Add(cc);
}

CreateAnonymousForCertificateBindingElement()方法为匿名客户端身份验证和基于证书的服务身份验证提供绑定元素。因此，如果要求提供服务证书。
