Windows 客户端的消息安全

  • 项目

此方案显示受消息安全模式保护的 Windows Communication Foundation (WCF) 客户端和服务器。 客户端和服务使用 Windows 凭据进行身份验证。

Message security with a Windows client

特征 说明

身份验证（服务器） 服务器和客户端的相互身份验证
身份验证（客户端） 服务器和客户端的相互身份验证
完整性 是，使用共享安全上下文
机密性 是，使用共享安全上下文
Transport NET.TCP
绑定 NetTcpBinding

服务

下面的代码和配置应独立运行。 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一个使用消息安全来建立 Windows 计算机安全上下文的服务终结点。

// 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()

配置

下面的配置可代替代码用于设置服务：

<?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>

客户端

下面的代码和配置应独立运行。 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自变量的客户端构造函数。 例如：

    CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");

    Dim cc As New CalculatorClient("EndpointConfigurationName")

代码

下面的代码创建客户端。 绑定设置为 Message 安全模式，客户端凭据类型设置为 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

配置

下面的配置用于设置客户端属性。

<?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>
