Как настраивать клиент WCF для взаимодействия со службами WSE 3.0

Статья
02/28/2011

Клиенты Windows Communication Foundation (WCF) на уровне линий связи совместимы со службами расширений веб-служб версии 3.0 для Microsoft .NET (WSE), если клиенты WCF настроены на использование спецификации WS-Addressing версии августа 2004 г.

Настройка клиента WCF для взаимодействия с веб-службой WSE 3.0

Запустите средство Служебное средство ServiceModel Metadata Utility Tool (Svcutil.exe), чтобы создать клиент WCF для веб-службы WSE 3.0.

Для веб-службы WSE создается класс клиента WCF.

Сведения о создании клиента WCF см. в разделе Как создать клиент Windows Communication Foundation.

Создайте класс, представляющий привязку, которая может обмениваться данными с веб-службами WSE 3.0.

Следующий класс является частью примера Interoperating with WSE.

Создайте класс, наследуемый от класса Binding.

В следующем примере кода создается класс с именем WseHttpBinding, наследуемый от класса Binding.
```
Public Class WseHttpBinding
    Inherits Binding
```
```
public class WseHttpBinding : Binding
{
```

Добавьте в класс свойства, задающие готовое к использованию утверждение WSE, требуются ли производные ключи, используются ли безопасные сеансы, требуется ли подтверждение подписей, и параметры защиты сообщений.

В следующем примере кода определяются свойства SecurityAssertion, RequireDerivedKeys, EstablishSecurityContext, MessageProtectionOrder, задающие готовое к использованию утверждение WSE, требуются ли производные ключи, используются ли безопасные сеансы, требуется ли подтверждение подписей, и задают параметры защиты сообщений соответственно.

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

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; }
}

Переопределите метод CreateBindingElements для задания свойств привязки.

В следующем примере кода транспорт, кодирование сообщений и параметры защиты сообщений задаются получением значений свойств SecurityAssertion и MessageProtectionOrder.

В коде клиентского приложения добавьте код для задания свойств привязки.

В следующем примере кода указывается, что клиент WCF должен использовать защиту сообщений и проверку подлинности в соответствии с готовым к использованию утверждением безопасности WSE 3.0 AnonymousForCertificate. Кроме того, требуются безопасные сеансы и производные ключи.
