我的主机中的Hadler错误EndPoint-WCF-行为 [英] Hadler Error EndPoint in my host - WCF - Behaviour
问题描述
几天前，我提出了一个问题，我能否成功回答.我没有很好地解决问题，现在又有了更多的知识.
A few days ago I opened a question if I succeed with the answers. I had not focused the question well, and now with something more knowledge I ask again.
我需要捕获所有端点的错误，以将它们包含在同一站点中.想法是向这些端点添加行为.
I need to capture the errors of all my endpoints to have them included in the same site. The idea is to add a behavior to these endpoints.
namespace SIPE.Search.Helpers
{
/// <summary>
/// Implements methods that can be used to extend run-time behavior for an endpoint in either a client application.
/// </summary>
public class ExternalClientBehavior : BehaviorExtensionElement
{
protected override object CreateBehavior()
{
return new ExternalClientBehaviorClass();
}
public override Type BehaviorType
{
get
{
return typeof(ExternalClientBehaviorClass);
}
}
/// <summary>
/// JSON REST[GET] Converter Behavior
/// </summary>
private class ExternalClientBehaviorClass : IEndpointBehavior
{
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
}
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
ExternalClientMessageInspector clientInspector = new ExternalClientMessageInspector(endpoint);
clientRuntime.MessageInspectors.Add(clientInspector);
foreach (ClientOperation op in clientRuntime.Operations)
{
op.ParameterInspectors.Add(clientInspector);
}
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
//("Behavior not supported on the consumer side!");
}
public void Validate(ServiceEndpoint endpoint)
{
}
}
}
}
现在，我知道，如果客户端未实现我的行为，它将永远不会输入我的ApplyDispatchBehaviour，而且这永远不会发生，因为它们是外部提供者，并且我无法访问代码.
Now I know that it will never enter my ApplyDispatchBehaviour if the client does not implement my behaviour, and this will NEVER happen, since they are external providers and I do not have access to the code.
此外，我的第一个错误甚至都没有留下我的代码，因为我引起了NOT FOUND错误.
Also, my first error does not even leave my code, since I'm causing a NOT FOUND error.
我发现了很多类似的问题，但都没有解决方案.我发现有几个站点在ApplyClientBehaviour中添加了以下内容:
I have found many similar sources with my problem without solution. I have found by several sites to add the following in ApplyClientBehaviour:
IErrorHandler errorHandler = new CustomErrorHandler();
clientRuntime.CallbackDispatchRuntime.ChannelDispatcher.ErrorHandlers.Add(errorHandler);
但这不起作用.
发生在我身上的其他来源: https://riptutorial.com/csharp/example/5460/implementing-ierrorhandler-for-wcf-services
Other sources that happened to me: https://riptutorial.com/csharp/example/5460/implementing-ierrorhandler-for-wcf-services
这不是解决方案，因为它用于服务行为.我需要在端点行为"中执行此操作.
It is NOT a solution, since it is for Services Behavior. I need to do it in EndPoint Behavior.
谢谢
推荐答案
请参考以下示例.
服务器端.
Please refer to the following example.
Server side.
class Program
{
static void Main(string[] args)
{
Uri uri = new Uri("http://localhost:1100");
BasicHttpBinding binding = new BasicHttpBinding();
using (ServiceHost sh = new ServiceHost(typeof(MyService), uri))
{
ServiceEndpoint se = sh.AddServiceEndpoint(typeof(IService), binding, "");
ServiceMetadataBehavior smb;
smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (smb == null)
{
smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.HttpGetUrl = new Uri("http://localhost:1100/mex");
sh.Description.Behaviors.Add(smb);
}
MyEndpointBehavior bhv = new MyEndpointBehavior();
se.EndpointBehaviors.Add(bhv);
sh.Open();
Console.WriteLine("service is ready");
Console.ReadKey();
sh.Close();
}
}
}
[ServiceContract(ConfigurationName = "isv")]
public interface IService
{
[OperationContract]
string Delete(int value);
[OperationContract]
void UpdateAll();
}
[ServiceBehavior(ConfigurationName = "sv")]
public class MyService : IService
{
public string Delete(int value)
{
if (value <= 0)
{
throw new ArgumentException("Parameter should be greater than 0");
}
return "Hello";
}
public void UpdateAll()
{
throw new InvalidOperationException("Operation exception");
}
}
public class MyCustomErrorHandler : IErrorHandler
{
public bool HandleError(Exception error)
{
return true;
}
public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
{
FaultException faultException = new FaultException(error.Message);
MessageFault messageFault = faultException.CreateMessageFault();
fault = Message.CreateMessage(version, messageFault, error.Message);
}
}
public class MyEndpointBehavior : IEndpointBehavior
{
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
return;
}
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
return;
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
MyCustomErrorHandler myCustomErrorHandler = new MyCustomErrorHandler();
endpointDispatcher.ChannelDispatcher.ErrorHandlers.Add(myCustomErrorHandler);
}
public void Validate(ServiceEndpoint endpoint)
{
return;
}
}
客户.
static void Main(string[] args)
{
ServiceReference1.ServiceClient client = new ServiceReference1.ServiceClient();
try
{
client.Delete(-3);
}
catch (FaultException fault)
{
Console.WriteLine(fault.Reason.GetMatchingTranslation().Text);
}
}
结果.
随时让我知道是否有什么可以帮助您的.
Result.
