我想使用ELMAH配置使用SQL Server进行日志记录。我遇到了以下问题：
内容类型text / html;响应消息的charset = utf-8与绑定的内容类型不匹配（application / soap + xml; charset = utf-8）。如果使用自定义编码器，请确保正确实现IsContentTypeSupported方法。响应的前1024个字节是：
<!DOCTYPE html> <html> <head> <title>Configuration Error</title> <meta name="viewport" content="width=device-width" /> <style> body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px} b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px}.....
这是我的服务web.config：

这位于另一个托管层项目中。我的服务类和合同在另一个项目中的位置。它们被映射在一起进行自我托管。
我添加了以下类和属性：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Dispatcher;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;
using System.Collections.ObjectModel;
using System.Net;
using System.Web;
using System.IO;
using Elmah;
namespace Logging
{
public class ElmahErrorHandler : IErrorHandler
{
public bool HandleError(Exception error)
{
return false;
}
public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
{
if (error == null)
{
return;
}
if (HttpContext.Current == null)
{
return;
}
Elmah.ErrorSignal.FromCurrentContext().Raise(error);
}
}
public class ServiceErrorBehaviorAttribute : Attribute, IServiceBehavior
{
Type errorHandlerType;
public ServiceErrorBehaviorAttribute(Type errorHandlerType)
{
this.errorHandlerType = errorHandlerType;
}
public void AddBindingParameters(ServiceDescription serviceDescription,
System.ServiceModel.ServiceHostBase serviceHostBase,
System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints,
System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
{
}
public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
{
IErrorHandler errorHandler;
errorHandler = (IErrorHandler)Activator.CreateInstance(errorHandlerType);
foreach (ChannelDispatcherBase cdb in serviceHostBase.ChannelDispatchers)
{
ChannelDispatcher cd = cdb as ChannelDispatcher;
cd.ErrorHandlers.Add(errorHandler);
}
}
public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
{
}
}
public class HttpErrorHandler : IErrorHandler
{
public bool HandleError(Exception error)
{
return false;
}
public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
{
//if (error != null) // Notify ELMAH of the exception.
//{
// Elmah.ErrorSignal.FromCurrentContext().Raise(error);
//}
if (error == null)
return;
if (HttpContext.Current == null) //In case we run outside of IIS
return;
Elmah.ErrorSignal.FromCurrentContext().Raise(error);
}
}
}
在我的服务层而非托管层。并用以下内容装饰我的服务类：
[ServiceErrorBehavior(typeof(HttpErrorHandler))]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
现在故意在我的服务方法中添加了ab异常。但是在执行时我得到了例外，如上所述。有人可以帮帮我吗？
