我正在尝试返回一个视图,不会根据我的应用程序可能发生的某些错误向用户发出重定向,我想处理错误+在基本控制器中记录它们,我不希望错误传播直到我的Global.asax - Application_Error()方法,因为我希望这个方法能够处理我的应用程序中的任何其他错误,例如用户输入虚假URL,有没有人找到解决方法?
注意:我已经离开了我的注释代码,因为我有一些问题的解决方法,这也表明我有可能处理的多个例外......
编辑:如果我在这个OnException覆盖中发出RedirectToAction,一切都按预期工作,但我只想返回视图而没有重定向......
我的基本控制器方法是:
protected override void OnException(ExceptionContext filterContext)
{
//dont interfere if the exception is already handled
if (filterContext.ExceptionHandled)
return;
//let the next request know what went wrong
filterContext.Controller.TempData["exception"] = filterContext.Exception;
//log exception
_logging.Error(User.Identity.Name, ExceptionHelper.BuildWebExceptionMessage(filterContext.Exception));
//set up redirect to my global error handler
//if (filterContext.Exception.GetType() == typeof(NoAccessException))
// filterContext.Result = View(new RouteValueDictionary
// (new { area = "", controller = "Error", action = "PublicError" }));
//else {
//Only return view, no need for redirection
filterContext.Result = View(new RouteValueDictionary
(new { area = "", controller = "Error", action = "NoAccess" }));
//}
//advise subsequent exception filters not to interfere and stop
// asp.net from showing yellow screen of death
filterContext.ExceptionHandled = true;
//erase any output already generated
filterContext.HttpContext.Response.Clear();
//base.OnException(filterContext);
}
此方法应该处理可能出现在我的应用程序中的任何其他错误,我不希望上面的错误在我的Application_Error()中处理
protected void Application_Error()
{
Exception exception = Server.GetLastError();
// Log the exception.
var logger = Container.Get<ILoggingService>();
logger.Error(User.Identity.Name, ExceptionHelper.BuildWebExceptionMessage(exception));
Response.Clear();
HttpException httpException = exception as HttpException;
RouteData routeData = new RouteData();
routeData.Values.Add("controller", "Error");
//if (httpException == null)
//{
routeData.Values.Add("action", "PublicError");
//}
//else //It's an Http Exception, Let's handle it.
//{
// switch (httpException.GetHttpCode())
// {
// case 404:
// // Page not found.
// routeData.Values.Add("action", "HttpError404");
// break;
// case 500:
// // Server error.
// routeData.Values.Add("action", "HttpError500");
// break;
// // Here you can handle Views to other error codes.
// // I choose a General error template
// default:
// routeData.Values.Add("action", "General");
// break;
// }
//}
// Pass exception details to the target error View.
routeData.Values.Add("error", exception);
// Clear the error on server.
Server.ClearError();
// Avoid IIS7 getting in the middle
Response.TrySkipIisCustomErrors = true;
// Call target Controller and pass the routeData.
IController errorController = new ErrorController();
errorController.Execute(new RequestContext(
new HttpContextWrapper(Context), routeData));
}

以下内容应该有效:
protected override void OnException(ExceptionContext filterContext)
{
if (filterContext.ExceptionHandled)
{
return;
}
filterContext.Result = new ViewResult
{
ViewName = "~/Views/Shared/Error.aspx"
};
filterContext.ExceptionHandled = true;
}
此外,请确保此方法不会引发异常,否则会传播到Application_Error
。
