Question

我正在从App.config迁移到以编程方式进行迁移，以调用具有客户端证书身份验证/身份的WCF服务。新代码是.NET Core，但是测试控制台应用程序的目标框架已设置为net472，以便它可以在Azure Kudu中运行。

我到处搜索，但无法摆脱此错误消息。

错误：

未处理的异常：System.ServiceModel.Security.MessageSecurityException：传出消息的身份检查失败。对于“ net.tcp：// myserver：1001 / MyServiceRelay / MyServiceRelay.svc”目标端点，期望的身份是“ identity（http://schemas.xmlsoap.org/ws/2005/05/identity/right/possessproperty：http://schemas.xmlsoap.org/ws/2005/05/identity/claims/thumbprint）”。

服务器堆栈跟踪：在System.ServiceModel.Security.IdentityVerifier.EnsureIdentity（EndpointAddress serviceReference，AuthorizationContextauthorizationContext，String errorString）在System.ServiceModel.Security.MessageSecurityProtocol.EnsureOutgoingIdentity（SecurityToken令牌，SecurityTokenAuthenticator身份验证器）处

App.config：

<endpoint name="MyEndpoint"
                address="[PLACEHOLDER]"
                binding="netTcpBinding"
                bindingConfiguration="NetTcpAzureBinding"
                behaviorConfiguration="AzureCertificateBehavior"
                contract="MyCalledService">
        <identity>
          <certificate encodedValue="[PLACEHOLDER]" />
        </identity>
 </endpoint>

<netTcpBinding>
        <binding name="NetTcpAzureBinding" maxReceivedMessageSize="20485760">
          <readerQuotas maxArrayLength="20485760" maxStringContentLength="20485760" />
          <security mode="Message">
            <message clientCredentialType="Certificate" />
          </security>
        </binding>
 </netTcpBinding>

<behavior name="AzureCertificateBehavior">
          <clientCredentials>
            <clientCertificate storeName="My" storeLocation="CurrentUser" x509FindType="FindByThumbprint" findValue="[PLACEHOLDER]" />
            <serviceCertificate>
              <authentication certificateValidationMode="None" revocationMode="NoCheck" />
            </serviceCertificate>
          </clientCredentials>
 </behavior>

等效于代码：

// My FindCertificate method performs a lookup by thumbprint, exactly the same code that below when using "SetCertificate".
X509Certificate2 certificate = Common.FindCertificate(settings.CertificateThumbprint);
        var binding = new NetTcpBinding
        {
            // custom constant
            MaxReceivedMessageSize = Common.MaxReceivedMessageSize
        };
        // custom constant
        binding.ReaderQuotas.MaxArrayLength = Common.MaxArrayLength;
        // custom constant
        binding.ReaderQuotas.MaxStringContentLength = Common.MaxStringContentLength;

        binding.Security.Mode = SecurityMode.Message;
        binding.Security.Message.ClientCredentialType = MessageCredentialType.Certificate;

        var endpoint = new EndpointAddress(new Uri(settings.MailService.EndpointAddress), EndpointIdentity.CreateX509CertificateIdentity(certificate));

        _channelFactory = new ChannelFactory<IMailService>(binding, endpoint);

        _channelFactory.Credentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindByThumbprint, settings.CertificateThumbprint);
        _channelFactory.Credentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;
        _channelFactory.Credentials.ServiceCertificate.Authentication.RevocationMode = X509RevocationMode.NoCheck;

怎么了？感谢您的想法。

好吧，什么都没有“错”，但是错误消息并不令人满意。一旦得到它，我只需要更换：

EndpointIdentity.CreateX509CertificateIdentity(certificate)

作者：

EndpointIdentity.CreateDnsIdentity(settings.MailService.EndpointDns)

端点身份初始化中的

。期望值在错误消息中...

帮助我的是建立一个通道工厂，该工厂通过将经典的.config文件读取到配置类来进行初始化：

        ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
        fileMap.ExeConfigFilename = "MailService.config";
        Configuration newConfiguration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

        _channelFactory = new ConfigurationChannelFactory<IMailService>("MyEndpoint", newConfiguration, new EndpointAddress("net.tcp://myserver:1001/MyServiceRelay/MyServiceRelay.svc"));

（嗯，这没有成功调用端点，只是提供了一个线索）。

仍然存在一个问题：为什么经典配置在不抱怨端点DNS的情况下仍能正常工作？我再次检查。我回想起2010年有关此安全检查的内容（防止网络欺诈）。同样有用：https://docs.microsoft.com/en-us/dotnet/framework/wcf/feature-details/service-identity-and-authentication
