匿名用戶端的訊息安全性

發行項
02/28/2011

下列案例會顯示 Windows Communication Foundation (WCF) 訊息安全性所保護的用戶端和服務。這樣的設計目的是使用訊息安全性而非傳輸安全性，如此未來可以支援更豐富的宣告型模型。如需詳細資訊使用各種宣告進行授權的詳細資訊，請參閱使用身分識別模型來管理宣告與授權。

如需範例應用程式，請參閱訊息安全性匿名

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.None

' Create the URI for the endpoint.
Dim httpUri As New Uri("https://localhost/Calculator")

' Create the service host and add an endpoint.
Dim myServiceHost As New ServiceHost(GetType(ServiceModel.Calculator), httpUri)
myServiceHost.AddServiceEndpoint(GetType(ServiceModel.ICalculator), binding, "")

' Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, _
StoreName.My, X509FindType.FindByThumbprint, "00000000000000000000000000000000")

' 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.None;

// Create the URI for the endpoint.
Uri httpUri = new Uri("https://localhost/Calculator");

// Create the service host and add an endpoint.
ServiceHost myServiceHost =
    new ServiceHost(typeof(ServiceModel.Calculator), httpUri);
myServiceHost.AddServiceEndpoint(
    typeof(ServiceModel.ICalculator), binding, "");

// Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.SetCertificate(
    StoreLocation.LocalMachine,
    StoreName.My,
    X509FindType.FindByThumbprint,
    "00000000000000000000000000000000");

// Open the service.
myServiceHost.Open();
Console.WriteLine("Listening...");
Console.ReadLine();

// Close the service.
myServiceHost.Close();

組態

可使用以下組態來取代程式碼。使用服務行為項目來指定用來驗證用戶端服務的憑證。服務項目必須使用 behaviorConfiguration 屬性來指定行為。繫結項目會指定用戶端認證類型為 None，因此可讓匿名用戶端使用服務。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceCredentialsBehavior">
          <serviceCredentials>
            <serviceCertificate findValue="contoso.com" 
                                storeLocation="LocalMachine"
                                storeName="My" />
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="ServiceCredentialsBehavior" 
               name="ServiceModel.Calculator">
        <endpoint address="https://localhost/Calculator" 
                  binding="wsHttpBinding"
                  bindingConfiguration="WSHttpBinding_ICalculator" 
                  name="CalculatorService"
                  contract="ServiceModel.ICalculator" />
      </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_ICalculator" >
          <security mode="Message">
            <message clientCredentialType="None" />
          </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的執行個體。繫結會使用訊息模式安全性，而且用戶端認證類型設為 none。

' Create the binding.
Dim myBinding As New WSHttpBinding()
myBinding.Security.Mode = SecurityMode.Message
myBinding.Security.Message.ClientCredentialType = MessageCredentialType.None

' Create the endpoint address. 
Dim ea As New EndpointAddress("https://localhost/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.None;

// Create the endpoint address. 
EndpointAddress ea = new
    EndpointAddress("https://localhost/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();
}

組態

下列程式碼會設定用戶端。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_ICalculator" >
          <security mode="Message">
            <message clientCredentialType="None" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://machineName/Calculator"
        binding="wsHttpBinding"
        bindingConfiguration="WSHttpBinding_ICalculator" 
        contract="ICalculator"
        name="WSHttpBinding_ICalculator">
        <identity>
          <dns value="contoso.com" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>
