WCF引发服务器拒绝客户端凭据的异常，这是WCF中NetTCP的默认安全模式

Question

WCF作为一个windows服务部署在服务器中。客户端是一个windows窗体应用程序。当客户端与WCF服务器交互时，这里是否正在进行任何类型的身份验证？

我知道如何在这里解决这个问题

我想知道WCF中NetTCP的默认安全模式是什么？我的配置文件中没有任何与安全相关的内容，如下所示。那么，默认情况是什么呢？

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<behaviors>
<serviceBehaviors>
<behavior name="BasicServiceBehavior">
<serviceMetadata httpGetEnabled="false"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="HCCNetTcpBinding" >
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="BasicServiceBehavior" name="HCC.SMS4.SERVICES.BASIC.MainServices">
<endpoint address="" binding="netTcpBinding" contract="HCC.SMS4.SERVICES.BASIC.IMainServices" bindingConfiguration="HCCNetTcpBinding" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<host>

openTimeout="14:00:00" receiveTimeout="14:00:00" sendTimeout="14:00:00">

</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>

Answer 1

NetTcpBinding的传输安全模式为transport，ClientCredentialType为Windows。这相当于以下设置。

<netTcpBinding>
<binding name="netTcp">
<security mode="Transport">
<transport clientCredentialType="Windows" />
</security>
</binding>
</netTcpBinding>

因此，当您使用客户端代理类来调用服务时，可以参考以下代码。

ServiceReference1.ServiceClient client = new ServiceReference1.ServiceClient();
client.ClientCredentials.Windows.ClientCredential.UserName = "administrator";
client.ClientCredentials.Windows.ClientCredential.Password = "abcd1234!";
var result = client.SayHello();

Answer 2

WCF，如果没有任何配置，它的默认身份验证是Windows。

Answer 3

根据NetTcpBinding的Microsoft文档，默认安全性为TLS和Windows安全性。
