作法:將 WCF 用戶端設為與 WSE3.0 服務交互操作
當 Windows Communication Foundation (WCF) 用戶端設定為使用 WS-Addressing 的 2004 年 8 月版本規格時,WCF 用戶端的連線層級會與適用 Microsoft .NET 的 Web 服務增強 3.0 (WSE) 服務相容。
將 WCF 用戶端設定為與 WSE 3.0 Web 服務交互操作
執行 ServiceModel 中繼資料公用程式工具 (Svcutil.exe),以為 WSE 3.0 Web 服務建立 WCF 用戶端。
針對 WSE Web 服務,會建立 WCF 用戶端類別。
如需建立 WCF 用戶端的詳細資訊,請參閱 如何:建立用戶端。
建立類別,表示可與 WSE 3.0 Web 服務通訊的繫結。
下列類別是 與 WSE 交互操作 範例的一部分。
建立從 Binding 類別衍生的類別。
下列程式碼範例會建立一個名為
WseHttpBinding
的類別,此類別衍生自 Binding 類別。public class WseHttpBinding : Binding {
Public Class WseHttpBinding Inherits Binding
將屬性加入至類別,以指定 WSE 通行判斷提示 (Turnkey Assertion)、是否需要衍生金鑰、是否使用安全工作階段、是否需要簽章確認,以及訊息保護設定。
下列程式碼範例定義
SecurityAssertion
、RequireDerivedKeys
、EstablishSecurityContext
和MessageProtectionOrder
屬性。 這些屬性分別指定 WSE 周全的判斷提示、是否需要衍生金鑰、是否使用安全工作階段、是否需要簽章確認,以及訊息保護設定。private WseSecurityAssertion assertion; public WseSecurityAssertion SecurityAssertion { get { return assertion; } set { assertion = value; } } private bool requireDerivedKeys; public bool RequireDerivedKeys { get { return requireDerivedKeys; } set { requireDerivedKeys = value; } } private bool establishSecurityContext; public bool EstablishSecurityContext { get { return establishSecurityContext; } set { establishSecurityContext = value; } } private bool requireSignatureConfirmation; public bool RequireSignatureConfirmation { get { return requireSignatureConfirmation; } set { requireSignatureConfirmation = value; } } private MessageProtectionOrder messageProtectionOrder; public MessageProtectionOrder MessageProtectionOrder { get { return messageProtectionOrder; } set { messageProtectionOrder = value; } }
Public Property SecurityAssertion() As WseSecurityAssertion Get Return assertion End Get Set(ByVal value As WseSecurityAssertion) assertion = value End Set End Property Private m_requireDerivedKeys As Boolean Public Property RequireDerivedKeys() As Boolean Get Return m_requireDerivedKeys End Get Set(ByVal value As Boolean) m_requireDerivedKeys = value End Set End Property Private m_establishSecurityContext As Boolean Public Property EstablishSecurityContext() As Boolean Get Return m_establishSecurityContext End Get Set(ByVal value As Boolean) m_establishSecurityContext = value End Set End Property Private m_requireSignatureConfirmation As Boolean Public Property RequireSignatureConfirmation() As Boolean Get Return m_requireSignatureConfirmation End Get Set(ByVal value As Boolean) m_requireSignatureConfirmation = value End Set End Property Private m_messageProtectionOrder As MessageProtectionOrder Public Property MessageProtectionOrder() As MessageProtectionOrder Get Return m_messageProtectionOrder End Get Set(ByVal value As MessageProtectionOrder) m_messageProtectionOrder = value End Set End Property
覆寫 CreateBindingElements 方法來設定繫結屬性。
下列程式碼範例會藉由取得
SecurityAssertion
和MessageProtectionOrder
屬性的值,指定傳輸、訊息編碼和訊息保護設定。public override BindingElementCollection CreateBindingElements() { //SecurityBindingElement sbe = bec.Find<SecurityBindingElement>(); BindingElementCollection bec = new BindingElementCollection(); // By default http transport is used SecurityBindingElement securityBinding; BindingElement transport; switch (assertion) { case WseSecurityAssertion.UsernameOverTransport: transport = new HttpsTransportBindingElement(); securityBinding = (TransportSecurityBindingElement)SecurityBindingElement.CreateUserNameOverTransportBindingElement(); if (establishSecurityContext == true) throw new InvalidOperationException("Secure Conversation is not supported for this Security Assertion Type"); if (requireSignatureConfirmation == true) throw new InvalidOperationException("Signature Confirmation is not supported for this Security Assertion Type"); break; case WseSecurityAssertion.MutualCertificate10: transport = new HttpTransportBindingElement(); securityBinding = SecurityBindingElement.CreateMutualCertificateBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10); if (requireSignatureConfirmation == true) throw new InvalidOperationException("Signature Confirmation is not supported for this Security Assertion Type"); ((AsymmetricSecurityBindingElement)securityBinding).MessageProtectionOrder = messageProtectionOrder; break; case WseSecurityAssertion.UsernameForCertificate: transport = new HttpTransportBindingElement(); securityBinding = (SymmetricSecurityBindingElement)SecurityBindingElement.CreateUserNameForCertificateBindingElement(); // We want signatureconfirmation on the bootstrap process // either for the application messages or for the RST/RSTR ((SymmetricSecurityBindingElement)securityBinding).RequireSignatureConfirmation = requireSignatureConfirmation; ((SymmetricSecurityBindingElement)securityBinding).MessageProtectionOrder = messageProtectionOrder; break; case WseSecurityAssertion.AnonymousForCertificate: transport = new HttpTransportBindingElement(); securityBinding = (SymmetricSecurityBindingElement)SecurityBindingElement.CreateAnonymousForCertificateBindingElement(); ((SymmetricSecurityBindingElement)securityBinding).RequireSignatureConfirmation = requireSignatureConfirmation; ((SymmetricSecurityBindingElement)securityBinding).MessageProtectionOrder = messageProtectionOrder; break; case WseSecurityAssertion.MutualCertificate11: transport = new HttpTransportBindingElement(); securityBinding = SecurityBindingElement.CreateMutualCertificateBindingElement(MessageSecurityVersion.WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11); ((SymmetricSecurityBindingElement)securityBinding).RequireSignatureConfirmation = requireSignatureConfirmation; ((SymmetricSecurityBindingElement)securityBinding).MessageProtectionOrder = messageProtectionOrder; break; case WseSecurityAssertion.Kerberos: transport = new HttpTransportBindingElement(); securityBinding = (SymmetricSecurityBindingElement)SecurityBindingElement.CreateKerberosBindingElement(); ((SymmetricSecurityBindingElement)securityBinding).RequireSignatureConfirmation = requireSignatureConfirmation; ((SymmetricSecurityBindingElement)securityBinding).MessageProtectionOrder = messageProtectionOrder; break; default: throw new NotSupportedException("This supplied Wse security assertion is not supported"); } //Set defaults for the security binding securityBinding.IncludeTimestamp = true; // Derived Keys // set the preference for derived keys before creating SecureConversationBindingElement securityBinding.SetKeyDerivation(requireDerivedKeys); //Secure Conversation if (establishSecurityContext == true) { SymmetricSecurityBindingElement secureconversation = (SymmetricSecurityBindingElement)SymmetricSecurityBindingElement.CreateSecureConversationBindingElement( securityBinding, false); // This is the default //secureconversation.DefaultProtectionLevel = ProtectionLevel.EncryptAndSign; //Set defaults for the secure conversation binding secureconversation.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256; // We do not want signature confirmation on the application level messages // when secure conversation is enabled. secureconversation.RequireSignatureConfirmation = false; secureconversation.MessageProtectionOrder = messageProtectionOrder; secureconversation.SetKeyDerivation(requireDerivedKeys); securityBinding = secureconversation; } // Add the security binding to the binding collection bec.Add(securityBinding); // Add the message encoder.

在用戶端應用程式程式碼中,加入程式碼以設定繫結屬性。
下列程式碼範例會指定 WCF 用戶端必須依照 WSE 3.0
AnonymousForCertificate
周全的安全性判斷提示所定義,使用訊息保護和驗證。 此外,也需要安全工作階段和衍生金鑰。static void CallWseService(bool usePolicyFile) { EndpointAddress address = new EndpointAddress(new Uri("http://localhost/WSSecurityAnonymousPolicy/WSSecurityAnonymousService.asmx"), EndpointIdentity.CreateDnsIdentity("WSE2QuickStartServer")); WseHttpBinding binding = new WseHttpBinding(); if (!usePolicyFile) { binding.SecurityAssertion = WseSecurityAssertion.AnonymousForCertificate; binding.EstablishSecurityContext = true; binding.RequireDerivedKeys = true; binding.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt; } else { binding.LoadPolicy("..\\wse3policyCache.config", "ServerPolicy"); } WSSecurityAnonymousServiceSoapClient client = new WSSecurityAnonymousServiceSoapClient(binding, address);
Private Shared Sub CallWseService(ByVal usePolicyFile As Boolean) Dim address As New EndpointAddress(New Uri("http://localhost/WSSecurityAnonymousPolicy/WSSecurityAnonymousService.asmx"), EndpointIdentity.CreateDnsIdentity("WSE2QuickStartServer")) Dim binding As New WseHttpBinding() If Not usePolicyFile Then binding.SecurityAssertion = WseSecurityAssertion.AnonymousForCertificate binding.EstablishSecurityContext = True binding.RequireDerivedKeys = True binding.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt Else binding.LoadPolicy("..\wse3policyCache.config", "ServerPolicy") End If Dim client As New WSSecurityAnonymousServiceSoapClient(binding, address)
