使用者名稱用戶端的訊息安全性
下圖示範使用訊息層級安全性保護的 Windows Communication Foundation (WCF) 服務與用戶端。 服務會使用 X.509 憑證來進行驗證。 用戶端會使用使用者名稱與密碼來進行驗證。
如需範例應用程式，請參閱訊息安全性使用者名稱。

服務
下列程式碼和組態要獨立執行。 執行下列其中一項：
使用不含組態的程式碼建立獨立服務。
使用提供的組態建立服務，但不要定義任何端點。
程式碼
下列程式碼會顯示如何建立會使用訊息安全性的服務端點。
' 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();
組態
可使用下列組態來取代程式碼：
<?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>
用戶端
程式碼
下列程式碼會建立用戶端。 繫結會使用訊息模式安全性，而且用戶端認證類型設為 UserName。 使用者名稱和密碼只能使用程式碼 (它是不可設定的) 來指定。 在此不示範傳回使用者名稱與密碼的程式碼，因為必須在應用程式層級才能完成這個動作。 例如，使用 [Window 表單] 對話方塊查詢使用者的資料。
' 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();
}
