用户名客户端的消息安全
下面的示例演示了一个使用消息级安全进行保护的 Windows Communication Foundation (WCF) 服务和客户端。服务使用 X.509 证书进行身份验证。客户端使用用户名和密码进行身份验证。
有关示例应用程序，请参见用户名消息安全。

服务
下面的代码和配置应单独运行。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消息安全的服务终结点。
' Create the binding.
Dim binding As New WSHttpBinding()
binding.Security.Mode = SecurityMode.Message
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName
' Create the URI for the endpoint.
Dim httpUri As New Uri("https://localhost/Calculator")
' Create the service host.
Dim myServiceHost As New ServiceHost(GetType(ServiceModel.Calculator), httpUri)
myServiceHost.AddServiceEndpoint(GetType(ICalculator), binding, "")
' Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, _
StoreName.My, X509FindType.FindBySubjectName, "Contoso.com")
myServiceHost.Open()
Console.WriteLine("Listening...")
Console.ReadLine()
' Close the service.
myServiceHost.Close()
// Create the binding.
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Message;
binding.Security.Message.ClientCredentialType =
MessageCredentialType.UserName;
// Create the URI for the endpoint.
Uri httpUri = new Uri("https://localhost/Calculator");
// Create the service host.
ServiceHost myServiceHost =
new ServiceHost(typeof(Calculator), httpUri);
myServiceHost.AddServiceEndpoint(typeof(ICalculator), binding, "");
// Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.
SetCertificate(StoreLocation.LocalMachine,
StoreName.My,
X509FindType.FindBySubjectName,
"Contoso.com");
myServiceHost.Open();
Console.WriteLine("Listening...");
Console.ReadLine();
// Close the service.
myServiceHost.Close();
配置
以下配置可代替代码使用：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceCredentialsBehavior">
<serviceCredentials>
<serviceCertificate findValue="Contoso.com"
storeLocation="LocalMachine"
storeName="My"
x509FindType="FindBySubjectName" />
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="ServiceCredentialsBehavior"
name="ServiceModel.Calculator">
<endpoint address="https://localhost/Calculator"
binding="wsHttpBinding"
bindingConfiguration="MessageAndUserName"
name="SecuredByTransportEndpoint"
contract="ServiceModel.ICalculator" />
</service>
</services>
<bindings>
<wsHttpBinding>
<binding name="MessageAndUserName">
<security mode="Message">
<message clientCredentialType="UserName" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<client />
</system.serviceModel>
</configuration>
客户端
代码
下面的代码创建客户端。绑定设置为消息模式安全，客户端凭据类型设置为 UserName。用户名和密码只能使用代码指定（不可配置）。返回用户名和密码的代码未在此处显示，因为这必须在应用程序级完成。例如，使用 Window 窗体对话框查询用户以获得这些数据。
' Create the binding.
Dim myBinding As New WSHttpBinding()
myBinding.Security.Mode = SecurityMode.Message
myBinding.Security.Message.ClientCredentialType = _
MessageCredentialType.UserName
' Create the endpoint address.
Dim ea As New EndpointAddress("http://machineName/Calculator")
' Create the client.
Dim cc As New CalculatorClient(myBinding, ea)
' Set the user name and password. The code to
' return the user name and password is not shown here. Use
' an interface to query the user for the information.
cc.ClientCredentials.UserName.UserName = ReturnUsername()
cc.ClientCredentials.UserName.Password = ReturnPassword()
' 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.UserName;
// Create the endpoint address.
EndpointAddress ea = new
EndpointAddress("http://machineName/Calculator");
// Create the client.
CalculatorClient cc =
new CalculatorClient(myBinding, ea);
// Set the user name and password. The code to
// return the user name and password is not shown here. Use
// an interface to query the user for the information.
cc.ClientCredentials.UserName.UserName = ReturnUsername();
cc.ClientCredentials.UserName.Password = ReturnPassword();
// Begin using the client.
try
{
cc.Open();
Console.WriteLine(cc.Add(200, 1111));
Console.ReadLine();
// Close the client.
cc.Close();
}
