Windows 用戶端的訊息安全性

此案例顯示受訊息安全性模式保護的 Windows Communication Foundation （WCF） 客戶端和伺服器。 用戶端和服務會使用 Windows 認證進行驗證。

服務

下列程式代碼和組態是要獨立執行。 請執行下列其中一項動作：

• 使用不含組態的程式代碼建立獨立服務。

• 使用提供的組態建立服務，但不定義任何端點。

程式碼

下列程式碼示範如何建立一個使用訊息安全性、與 Windows 機器建立安全上下文的服務端點。

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

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

// Crate the service host and add an endpoint.
ServiceHost myServiceHost = new ServiceHost
    (typeof(Calculator), netTcpUri);
myServiceHost.AddServiceEndpoint(
    typeof(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.Message
binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows

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

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

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

' Close the service.
myServiceHost.Close()

設定

您可以使用下列設定，而不是程式代碼來設定服務：

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

客戶

下列程式代碼和組態是要獨立執行。 請執行下列其中一項動作：

• 使用程式代碼和客戶端代碼來建立獨立的用戶端。

• 建立未定義任何端點位址的用戶端。 請改用採用組態名稱作為自變數的用戶端建構函式。 例如：

  CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");
  

  Dim cc As New CalculatorClient("EndpointConfigurationName")
  

程式碼

下列程式代碼會建立用戶端。 繫結是訊息模式安全性，且客戶端認證類型設定為 Windows。

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

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

// Create the client.
CalculatorClient cc =
    new CalculatorClient(myBinding, ea);

// Begin using the client.
try
{
    cc.Open();
    Console.WriteLine(cc.Add(200, 1111));
    Console.ReadLine();

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

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

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

' Create the client.
Dim cc As New CalculatorClient(myBinding, ea)

' 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

設定

下列組態可用來設定客戶端屬性。

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