相互憑證的訊息安全性

  • 發行項

下列案例顯示使用訊息安全性模式加以保護的 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。

ms733102.note(zh-tw,VS.100).gif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：

  • 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. 
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("https://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()

// 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("https://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();

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="https://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：

  • 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：

    Dim cc As New CalculatorClient("EndpointConfigurationName")

    CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");

程式碼

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.
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("https://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

// 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();
}

組態

下列組態會設定用戶端。 用戶端憑證必須使用 <clientCertificate> of <clientCredentials> Element加以指定。 同時，服務憑證要使用 <defaultCertificate> Element加以指定。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="ClientCredentialsBehavior">
          <clientCredentials>
            <clientCertificate findValue="Cohowinery.com" 
                 storeLocation="CurrentUser"
                 storeName="My"
                 x509FindType="FindBySubjectName" />
            <serviceCertificate>
              <defaultCertificate findValue="Contoso.com" 
                                  storeLocation="CurrentUser"
                                  storeName="TrustedPeople"
                                  x509FindType="FindBySubjectName" />
            </serviceCertificate>
          </clientCredentials>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_ICalculator" >
          <security mode="Message">
            <message clientCredentialType="Certificate" 
                     negotiateServiceCredential="false"
                     establishSecurityContext="false" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://machineName/Calculator" 
                behaviorConfiguration="ClientCredentialsBehavior"
                binding="wsHttpBinding" 
                bindingConfiguration="WSHttpBinding_ICalculator"
                contract="ICalculator"
                name="WSHttpBinding_ICalculator">
        <identity>
          <certificate encodedValue="Encoded_Value_Not_Shown" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>
