无法使用正确的 web.config 将 IErrorHandler 集成到我的项目中
我有一个成功工作的 WCF，它被 .net 4 中的 webclients 使用，但是当尝试将 IErrorhandler 设置为全局错误记录器作为我所有服务方法的全部捕获时，事情很快就失败了 - 主要与 web.config 部分有关！请帮忙。
这三个服务分别是：IReport、IServiceCustomer、IServiceUser
在名为 MyErrorClass.cs 的单独类中实现 IErrorHandler，如下所示：
namespace CustomerWcfService
{
public class WcfErrorHandler : IErrorHandler
{
/// <summary>
/// Enables the creation of a custom <see cref="T:System.ServiceModel.FaultException`1"/> that is returned from an exception in the course of a service method.
/// </summary>
/// <param name="error">The <see cref="T:System.Exception"/> object thrown in the course of the service operation.</param><param name="version">The SOAP version of the message.</param><param name="fault">The <see cref="T:System.ServiceModel.Channels.Message"/> object that is returned to the client, or service, in the duplex case.</param>
public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
{
// can create custom error messages here
}
/// <summary>
/// Enables error-related processing and returns a value that indicates whether the dispatcher aborts the session and the instance context in certain cases.
/// </summary>
/// <returns>
/// true if should not abort the session (if there is one) and instance context if the instance context is not <see cref="F:System.ServiceModel.InstanceContextMode.Single"/>; otherwise, false. The default is false.
/// </returns>
/// <param name="error">The exception thrown during processing.</param>
public bool HandleError(Exception error)
{
// log error to database using legacy error handler
ErrorHandler.LogError(error);
// Let the other ErrorHandler do their jobs
return true;
}
}
public class WcfErrorServiceBehaviour : IServiceBehavior
{
/// <summary>
/// Provides the ability to inspect the service host and the service description to confirm that the service can run successfully.
/// </summary>
/// <param name="serviceDescription">The service description.</param><param name="serviceHostBase">The service host that is currently being constructed.</param>
public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
{ }
/// <summary>
/// Provides the ability to pass custom data to binding elements to support the contract implementation.
/// </summary>
/// <param name="serviceDescription">The service description of the service.</param><param name="serviceHostBase">The host of the service.</param><param name="endpoints">The service endpoints.</param><param name="bindingParameters">Custom objects to which binding elements have access.</param>
public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters)
{ }
/// <summary>
/// Provides the ability to change run-time property values or insert custom extension objects such as error handlers, message or parameter interceptors, security extensions, and other custom extension objects.
/// </summary>
/// <param name="serviceDescription">The service description.</param><param name="serviceHostBase">The host that is currently being built.</param>
public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
{
var handler = new WcfErrorHandler();
foreach (ChannelDispatcher dispatcher in serviceHostBase.ChannelDispatchers)
{
dispatcher.ErrorHandlers.Add(handler);
}
}
}
public class WcfErrorHandlerBehaviour : BehaviorExtensionElement
{
/// <summary>
/// Creates a behavior extension based on the current configuration settings.
/// </summary>
/// <returns>
/// The behavior extension.
/// </returns>
protected override object CreateBehavior() { return new WcfErrorServiceBehaviour(); }
/// <summary>
/// Gets the type of behavior.
/// </summary>
/// <returns>
/// A <see cref="T:System.Type"/>.
/// </returns>
public override Type BehaviorType { get { return typeof (WcfErrorServiceBehaviour); } }
}
}
web.config 应该是什么样子，因为我已经从网上的各种教程和答案中尝试了一百万种组合，但没有让它工作！当我不涉及 IErrorHandler 时，这就是 web.config 的原始工作摘录的样子
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
请有人可以将更正后的 web.config 发送给这个 WCF 菜鸟，因为我一直在删除并重试，却无处可去（我为此浪费了很多天）:(
