使用服務行為來輸入 WCF LOB 配接器 SDK 的認證

配接器取用者需要多次，才能將認證傳遞至目標企業營運系統。 若要提供這項功能，您必須提供 WCF 服務行為。

下列範例程式碼示範如何衍生服務行為。 它會將從配接器取用者取得的認證委派給配接器。 配接器接著必須使用企業營運通訊協定來驗證認證。 一旦認證通過驗證，服務就可以開始接聽來自企業營運應用程式的傳入事件。

/// <summary>  
/// This class derives from a WCF service behavior.  It is used in the inbound scenario  
/// for the Inbound Service to pass the line-of-business credentials to the adapter using  
/// WCF ClientCredentials class.  
/// </summary>  
public class InboundClientCredentialsServiceBehavior : ClientCredentials, IServiceBehavior  
{  
    public InboundClientCredentialsServiceBehavior() { }  
  
    public InboundClientCredentialsServiceBehavior(InboundClientCredentialsServiceBehavior other)  
         : base(other)  
    {  
    }  
  
    #region IServiceBehavior Members  
  
    public void AddBindingParameters(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)  
    {  
        bindingParameters.Add(this);  
    }  
  
    public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)  
    {  
    }  
  
    public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)  
    {  
    }  
  
    #endregion  
  
    protected override ClientCredentials CloneCore()  
    {  
        return new InboundClientCredentialsServiceBehavior(this);  
    }  
}  

下列範例程式碼示範如何使用服務行為將認證傳遞至配接器。

// Create a ServiceHost for the EchoServiceImpl type  
// and use the base address from app.config  
ServiceHost host = new ServiceHost(typeof(EchoServiceImpl));  
  
// Set service behavior to pass the line-of-business credentials.  
InboundClientCredentialsServiceBehavior credentialsBehavior = new InboundClientCredentialsServiceBehavior();  
credentialsBehavior.UserName.UserName = "username";  
credentialsBehavior.UserName.Password = "****";  
host.Description.Behaviors.Add(credentialsBehavior);  
  
// Open the ServiceHost to start listening for messages  
host.Open();  
  
Console.WriteLine("The service is ready.");  
Console.WriteLine("Press <ENTER> to terminate service.");  
Console.ReadLine();  
  
// Close the ServiceHost  
host.Close();
