wcf - 如何配置 WCF 以将 URN 格式的自定义领域与 Azure ACS 一起使用？

如何使我的 WCF 客户端使用 ACS 对内部托管的 WCF 服务进行身份验证？问题围绕设置自定义领域(我不知道如何设置。)

我的 ACS 配置类似于 the ACS Samples，但是“领域”的定义如下所示。

摘自 Azure ACS 配置页面



客户端代码

      EndpointAddress serviceEndpointAddress = new EndpointAddress( new Uri( "http://localhost:7000/Service/Default.aspx"),
                                                                      EndpointIdentity.CreateDnsIdentity( GetServiceCertificateSubjectName() ),
                                                                      new AddressHeaderCollection() );

        ChannelFactory<IStringService> stringServiceFactory = new ChannelFactory<IStringService>(Bindings.CreateServiceBinding("https://agent7.accesscontrol.appfabriclabs.com/v2/wstrust/13/certificate"), serviceEndpointAddress );

        // Set the service credentials.
        stringServiceFactory.Credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
        stringServiceFactory.Credentials.ServiceCertificate.DefaultCertificate = GetServiceCertificate();

        // Set the client credentials.
        stringServiceFactory.Credentials.ClientCertificate.Certificate = GetClientCertificateWithPrivateKey();

服务器端代码

 string acsCertificateEndpoint = String.Format( "https://{0}.{1}/v2/wstrust/13/certificate", AccessControlNamespace, AccessControlHostName );

        ServiceHost rpHost = new ServiceHost( typeof( StringService ) );

        rpHost.Credentials.ServiceCertificate.Certificate = GetServiceCertificateWithPrivateKey();

        rpHost.AddServiceEndpoint( typeof( IStringService ),
                                   Bindings.CreateServiceBinding( acsCertificateEndpoint ),
                                   "http://localhost:7000/Service/Default.aspx"
                                   );

        //
        // This must be called after all WCF settings are set on the service host so the
        // Windows Identity Foundation token handlers can pick up the relevant settings.
        //
        ServiceConfiguration serviceConfiguration = new ServiceConfiguration();
        serviceConfiguration.CertificateValidationMode = X509CertificateValidationMode.None;

        // Accept ACS signing certificate as Issuer.
        serviceConfiguration.IssuerNameRegistry = new X509IssuerNameRegistry( GetAcsSigningCertificate().SubjectName.Name );

        // Add the SAML 2.0 token handler.
        serviceConfiguration.SecurityTokenHandlers.AddOrReplace( new Saml2SecurityTokenHandler() );

        // Add the address of this service to the allowed audiences.
        serviceConfiguration.SecurityTokenHandlers.Configuration.AudienceRestriction.AllowedAudienceUris.Add( new Uri( "urn:federation:customer:222:agent:11") );

        FederatedServiceCredentials.ConfigureServiceHost( rpHost, serviceConfiguration );

        return rpHost;

... 其中 urn:federation:customer:222:agent:11 是依赖方 ID

... http://localhost:7000/Service/Default.aspx 是我希望上述 WCF/WIF 客户端在进行 ACS 身份验证后绑定(bind)到的位置。

问题

如何编辑上面的代码，以便客户端和服务器都可以针对某个端口 (localhost:700) 以及 urn:federation:customer:222:agent:11 的领域进行操作

我想我的服务器代码是正确的；但是如何在客户端设置 AudienceRestriction 呢？

最佳答案

您的服务器端代码看起来不错，但 Sixto 在标准 channel 工厂方面是正确的。幸运的是，您可以使用 WTrustChannelFactory 自己从 ACS 请求安全 token 。在您的示例上下文中，您的代码如下所示:

//
// Get the token from ACS
//
WSTrustChannelFactory trustChannelFactory = new WSTrustChannelFactory(
    Bindings.CreateAcsCertificateBinding(),
    new EndpointAddress( acsCertificateEndpoint ) );
trustChannelFactory.Credentials.ClientCertificate.Certificate = GetClientCertificateWithPrivateKey();

RequestSecurityToken rst = new RequestSecurityToken()
{
    RequestType = RequestTypes.Issue,
    AppliesTo = new EndpointAddress( new Uri( "urn:federation:customer:222:agent:11" ) ),
    KeyType = KeyTypes.Symmetric
};

WSTrustChannel wsTrustChannel = (WSTrustChannel)trustChannelFactory.CreateChannel();
SecurityToken token = wsTrustChannel.Issue( rst );

//
// Call StringService, authenticating with the retrieved token
//
WS2007FederationHttpBinding binding = new WS2007FederationHttpBinding( WSFederationHttpSecurityMode.Message );
binding.Security.Message.EstablishSecurityContext = false;
binding.Security.Message.NegotiateServiceCredential = false;

ChannelFactory<IStringService> factory = new ChannelFactory<IStringService>(
    binding,
    new EndpointAddress(
            new Uri( ServiceAddress ),
            EndpointIdentity.CreateDnsIdentity(GetServiceCertificateSubjectName()) ) );
factory.ConfigureChannelFactory<IStringService>();
factory.Credentials.SupportInteractive = false;
factory.Credentials.ServiceCertificate.DefaultCertificate = GetServiceCertificate();

IStringService channel = factory.CreateChannelWithIssuedToken<IStringService>( token );
string reversedString = channel.Reverse( "string to reverse" );
