Windows 客户端的消息安全
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。

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.
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:8006/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()
// 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();
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。绑定设置为 Message 安全模式，客户端凭据类型设置为 Windows。
' Create the binding.
Dim myBinding As New WSHttpBinding()
myBinding.Security.Mode = SecurityMode.Message
myBinding.Security.Message.ClientCredentialType = MessageCredentialType.Windows
' Create the endpoint address.
Dim ea As New EndpointAddress("https://localhost:90/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
// Create the binding.
WSHttpBinding myBinding = new WSHttpBinding();
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();
}
配置

</endpoint>
</client>
</system.serviceModel>
</configuration>
