相互憑證的訊息安全性
下列案例示範了透過訊息安全性模式保護 Windows Communication Foundation (WCF) 服務和用戶端。 用戶端與服務以憑證加以驗證。
因為案例使用具有 X.509 憑證權杖設定檔的 WS-Security,所以這個案例是互通的。
注意
這個案例並不執行服務憑證的交涉。 在任何通訊前,必須先對用戶端提供服務憑證。 伺服器憑證可在應用程式散發,或在超出範圍通訊中提供。

服務
下列程式碼和組態要獨立執行。 執行下列其中一項動作:
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。
代碼
下列程式碼顯示建立使用訊息安全性的服務端點。 服務需要憑證來驗證自己。
// Create the binding.
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Message;
binding.Security.Message.ClientCredentialType =
MessageCredentialType.Certificate;
binding.Security.Message.NegotiateServiceCredential = false;
binding.Security.Message.EstablishSecurityContext = false;
// Create the URI for the endpoint.
Uri httpUri = new Uri("http://localhost/Calculator");
// Create the service host.
ServiceHost myServiceHost =
new ServiceHost(typeof(Calculator), httpUri);
// Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(
StoreLocation.LocalMachine,
StoreName.My,
X509FindType.FindBySubjectName,
"contoso.com");
// Add an endpoint to the service.
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 WSHttpBinding()
binding.Security.Mode = SecurityMode.Message
binding.Security.Message.ClientCredentialType = _
MessageCredentialType.Certificate
binding.Security.Message.NegotiateServiceCredential = False
binding.Security.Message.EstablishSecurityContext = False
' Create the URI for the endpoint.
Dim httpUri As New Uri("http://localhost/Calculator")
' Create the service host.
Dim myServiceHost As New ServiceHost(GetType(ServiceModel.Calculator), httpUri)
' Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, _
StoreName.My, X509FindType.FindBySubjectName, "contoso.com")
' Add an endpoint to the service.
myServiceHost.AddServiceEndpoint(GetType(ICalculator), binding, "")
' Open the service.
myServiceHost.Open()
Console.WriteLine("Listening...")
Console.ReadLine()
' Close the service.
myServiceHost.Close()
組態
您可使用下列組態來取代程式碼,以建立相同的服務。
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="serviceCredentialBehavior">
<serviceCredentials>
<serviceCertificate findValue="Contoso.com"
storeLocation="LocalMachine"
storeName="My"
x509FindType="FindBySubjectName" />
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="serviceCredentialBehavior"
name="ServiceModel.Calculator">
<endpoint address="http://localhost/Calculator"
binding="wsHttpBinding"
bindingConfiguration="InteropCertificateBinding"
name="WSHttpBinding_ICalculator"
contract="ServiceModel.ICalculator" />
</service>
</services>
<bindings>
<wsHttpBinding>
<binding name="InteropCertificateBinding">
<security mode="Message">
<message clientCredentialType="Certificate"
negotiateServiceCredential="false"
establishSecurityContext="false" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<client />
</system.serviceModel>
</configuration>
用戶端
下列程式碼和組態要獨立執行。 執行下列其中一項動作:
使用此程式碼 (和用戶端程式碼) 建立獨立用戶端。
建立未定義任何端點位址的用戶端, 然後改用可接受組態名稱當做引數的用戶端建構函式。 例如:
CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");
Dim cc As New CalculatorClient("EndpointConfigurationName")
代碼
下列程式碼會建立用戶端。 安全性模式設為訊息,而且用戶端認證類型設為憑證。
// Create the binding.
WSHttpBinding myBinding = new WSHttpBinding();
myBinding.Security.Mode = SecurityMode.Message;
myBinding.Security.Message.ClientCredentialType =
MessageCredentialType.Certificate;
// Disable credential negotiation and the establishment of
// a security context.
myBinding.Security.Message.NegotiateServiceCredential = false;
myBinding.Security.Message.EstablishSecurityContext = false;
// Create the endpoint address.
EndpointAddress ea = new
EndpointAddress("http://machineName/Calculator");
// Create the client.
CalculatorClient cc =
new CalculatorClient(myBinding, ea);
// Specify a certificate to use for authenticating the client.
cc.ClientCredentials.ClientCertificate.SetCertificate(
StoreLocation.CurrentUser,
StoreName.My,
X509FindType.FindBySubjectName,
"Cohowinery.com");
// Specify a default certificate for the service.
cc.ClientCredentials.ServiceCertificate.SetDefaultCertificate(
StoreLocation.CurrentUser,
StoreName.TrustedPeople,
X509FindType.FindBySubjectName,
"Contoso.com");
// 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 WSHttpBinding()
myBinding.Security.Mode = SecurityMode.Message
myBinding.Security.Message.ClientCredentialType = MessageCredentialType.Certificate
' Disable credential negotiation and the establishment of
' a security context.
myBinding.Security.Message.NegotiateServiceCredential = False
myBinding.Security.Message.EstablishSecurityContext = False
' Create the endpoint address.
Dim ea As New EndpointAddress("http://localhost/Calculator")
' Create the client.
Dim cc As New CalculatorClient(myBinding, ea)
' Specify a certificate to use for authenticating the client.
cc.ClientCredentials.ClientCertificate.SetCertificate( _
StoreLocation.CurrentUser, StoreName.My, _
X509FindType.FindBySubjectName, "Cohowinery.com")
' Specify a default certificate for the service.
cc.ClientCredentials.ServiceCertificate.SetDefaultCertificate( _
StoreLocation.CurrentUser, StoreName.TrustedPeople, _
X509FindType.FindBySubjectName, "Contoso.com")
' 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
組態
下列組態會設定用戶端。 用戶端憑證必須透過 <clientCertificate> 加以指定。 此外,服務憑證則會透過 <defaultCertificate> 加以指定。
