如何为WCF IErrorhandler设置web.config [英] How to setup up web.config for WCF IErrorhandler
问题描述
无法使用正确的web.config将IErrorHandler集成到我的项目中
Can't integrate IErrorHandler into my project with the correct web.config
我有一个可以正常工作的WCF，.net 4中的webclient正在使用该WCF，但是当尝试将IErrorhandler设置为全局错误记录程序以捕获所有我的所有服务方法时，事情很快就失败了-主要是与Web有关.config部分！请帮忙.
I have a successfully working WCF that is being consumed by webclients in .net 4 but when trying to setup IErrorhandler as a global error logger as a catch all for all my service methods, things are failing fast - mainly to do with web.config part! Please help.
这三个服务是:IReport，IServiceCustomer，IServiceUser
The three services are: IReport, IServiceCustomer, IServiceUser
在名为MyErrorClass.cs的单独类中实现IErrorHandler，如下所示:
Implemented IErrorHandler in a seperate class called MyErrorClass.cs like this:
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); } }
}
}
当我从网络上的各种教程和答案中尝试了一百万种组合，但是却无法正常运行时，web.config应该是什么样子！这是我不涉及IErrorHandler时web.config原始工作摘录的样子
What should the web.config look like as I've tried a million combinations from various tutorials and answers on the net but doesnt get it working! This is how the original working extract of web.config looks when I'm not involving IErrorHandler
<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>
请有人可以将此WCF新手发送给更正后的web.config，因为我一直在删除并重试，却无处可寻(我在这上已经失去了很多天):(
Please can someone send this WCF noob the corrected web.config pleasee as I keep deleting and trying again and getting no where (i've lost so many days on this) :(
推荐答案
<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" />
<errorHandler/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<extensions>
<behaviorExtensions>
<add name="errorHandler" type="CustomerWcfService.WcfErrorHandlerBehaviour, CustomerWcfService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
</behaviorExtensions>
</extensions>
</system.serviceModel>
然后将您的行为应用于您希望将其应用到的服务.
And then apply your behavior to the service you want it to be applied to.
对不起，但是您实际上需要删除扩展定义中类型名称中的任何换行符和任何其他空格(旧的WCF错误迫使您在扩展类型声明中使用完全限定的名称字符串)
sorry for the miss, but you actually need to remove any line-break and any additional white space in the type name in the extension definition (old WCF bug which force you to use the fully qualified name string in extension type declaration).
