使用 Windows 身份验证实现传输安全性

以下方案显示了受 Windows 安全性保护的 Windows Communication Foundation （WCF） 客户端和服务。 有关编程的详细信息，请参阅 如何：使用 Windows 凭据保护服务。

Intranet Web 服务显示人力资源信息。 客户端是 Windows 窗体应用程序。 应用程序部署在由 Kerberos 控制器保护的域中。

服务

以下代码和配置旨在独立运行。 执行下列操作之一：

• 使用没有配置的代码创建独立服务。

• 使用提供的配置创建服务，但不定义任何终结点。

代码

以下代码演示如何创建使用 Windows 安全性的服务终结点。

// Create the binding.
NetTcpBinding binding = new NetTcpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType =
    TcpClientCredentialType.Windows;

// Create the URI for the endpoint.
Uri netTcpUri = new Uri("net.tcp://localhost:8008/Calculator");

// Create the service host and add an endpoint.
ServiceHost myServiceHost = new ServiceHost(typeof(Calculator), netTcpUri);
myServiceHost.AddServiceEndpoint(typeof(ServiceModel.ICalculator), binding, "");

// Open the service.
myServiceHost.Open();
Console.WriteLine("Listening...");
Console.ReadLine();

// Close the service.
myServiceHost.Close();

' Create the binding.
Dim binding As New NetTcpBinding()
binding.Security.Mode = SecurityMode.Transport
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows

' Create the URI for the endpoint.
Dim netTcpUri As New Uri("net.tcp://localhost:8008/Calculator")

' Create the service host and add an endpoint.
Dim myServiceHost As New ServiceHost(GetType(ServiceModel.Calculator), netTcpUri)
myServiceHost.AddServiceEndpoint(GetType(ServiceModel.ICalculator), binding, "")

' Open the service.
myServiceHost.Open()
Console.WriteLine("Listening...")
Console.ReadLine()

' Close the service.
myServiceHost.Close()

配置

可以使用以下配置来代替代码来设置服务终结点：

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
  <system.serviceModel>  
    <behaviors />  
    <services>  
      <service behaviorConfiguration="" name="ServiceModel.Calculator">  
        <endpoint address="net.tcp://localhost:8008/Calculator"
                  binding="netTcpBinding"  
          bindingConfiguration="WindowsClientOverTcp"
                  name="WindowsClientOverTcp"  
                  contract="ServiceModel.ICalculator" />  
      </service>  
    </services>  
    <bindings>  
      <netTcpBinding>  
        <binding name="WindowsClientOverTcp">  
          <security mode="Transport">  
            <transport clientCredentialType="Windows" />  
          </security>  
        </binding>  
      </netTcpBinding>  
    </bindings>  
    <client />  
  </system.serviceModel>  
</configuration>  

客户

以下代码和配置旨在独立运行。 执行下列操作之一：

• 使用代码（和客户端代码）创建独立客户端。

• 创建不定义任何终结点地址的客户端。 请改用采用配置名称作为参数的客户端构造函数。 例如：

  CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");
  

  Dim cc As New CalculatorClient("EndpointConfigurationName")
  

代码

以下代码创建客户端。 绑定配置为将传输模式安全性与 TCP 传输配合使用，并将客户端凭据类型设置为 Windows。

// Create the binding.
NetTcpBinding myBinding = new NetTcpBinding();
myBinding.Security.Mode = SecurityMode.Transport;
myBinding.Security.Transport.ClientCredentialType =
    TcpClientCredentialType.Windows;

// Create the endpoint address.
EndpointAddress myEndpointAddress = new
    EndpointAddress("net.tcp://localhost:8008/Calculator");

// Create the client. The code for the calculator client
// is not shown here. See the sample applications
// for examples of the calculator code.
CalculatorClient cc =
    new CalculatorClient(myBinding, myEndpointAddress);
try
{
    cc.Open();

    // Begin using the client.
    Console.WriteLine(cc.Add(100, 11));
    Console.ReadLine();

    // Close the client.
    cc.Close();
}

' Create the binding.
Dim myBinding As New NetTcpBinding()
myBinding.Security.Mode = SecurityMode.Transport
myBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows

' Create the endpoint address.
Dim myEndpointAddress As New EndpointAddress("net.tcp://localhost:8008/Calculator")

' Create the client. The code for the calculator client
' is not shown here. See the sample applications
' for examples of the calculator code.
Dim cc As New CalculatorClient(myBinding, myEndpointAddress)
cc.Open()
' Begin using the client.
Try
    cc.Open()

    Console.WriteLine(cc.Add(100, 11))
    Console.ReadLine()

    ' Close the client.
    cc.Close()
Catch tex As TimeoutException
    Console.WriteLine(tex.Message)
    cc.Abort()
Catch cex As CommunicationException
    Console.WriteLine(cex.Message)
    cc.Abort()
Finally
    Console.WriteLine("Closed the client")
    Console.ReadLine()
End Try

配置

可以使用以下配置而不是代码来创建客户端。

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
  <system.serviceModel>  
    <bindings>  
      <netTcpBinding>  
        <binding name="NetTcpBinding_ICalculator" >  
          <security mode="Transport">  
            <transport clientCredentialType="Windows" />  
          </security>  
        </binding>  
      </netTcpBinding>  
    </bindings>  
    <client>  
      <endpoint address="net.tcp://localhost:8008/Calculator"
                binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_ICalculator"
                contract="ICalculator"  
                name="NetTcpBinding_ICalculator">  
      </endpoint>  
    </client>  
  </system.serviceModel>  
</configuration>
