通过 Windows 身份验证确保的传输安全

  • 项目

下面的方案演示了受 Windows 安全保护的 Windows Communication Foundation (WCF) 客户端和服务。有关编程的更多信息，请参见如何：使用 Windows 凭据保护服务的安全。

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

服务

下面的代码和配置将独立运行。执行下列操作之一：

  • 使用代码（而不使用配置）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

下面的代码演示如何创建使用 Windows 安全的服务终结点。

' 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()

// 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();

配置

可以使用下面的配置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>

客户端

下面的代码和配置将独立运行。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。而使用将配置名称作为参数的客户端构造函数。例如：

    Dim cc As New CalculatorClient("EndpointConfigurationName")

    CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");

代码

下面的代码创建客户端。绑定配置为使用传输模式安全（采用 TCP 传输协议），并且客户端凭据类型设置为 Windows。

' 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

// 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();
}

配置

可以使用下面的配置代替代码来创建客户端。

<?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>
