[英]Serilog stops logging exceptions as soon as I add a custom ExceptionFilter
[英]How to allow custom ExceptionFilter to continue to call the designated Action Method during exceptions
當我的異常過濾器被調用時,我希望控制器中的預期動作仍然被調用。 我創建了以下IExceptionFilter:
public class ArgumentExceptionFilter : FilterAttribute, IExceptionFilter
{
public void OnException(ExceptionContext filterContext)
{
if (filterContext.Exception.GetType() == typeof(System.ArgumentException))
{
//Some logic to create a default "SettingsRoot" parameter
//This simply surpresses MVC from raising exception
filterContext.ExceptionHandled = true;
}
}
}
並將此過濾器應用於此控制器操作方法:
[ArgumentExceptionFilter]
public ActionResult MyActionMethod(SettingsRoot settings)
{
ActionResult actionResult = null;
//Do stuff with settings
return actionResult;
}
我希望有“ MyActionMethod()”被調用,無論我們是否得到觸發ExceptionFilter的異常。 我也嘗試使用“ RedirectToRouteResult()”方法,但是沒有用。 有什么建議么?
您可以使用filterContext的Result屬性使用默認參數重定向到控制器操作。
public void OnException(ExceptionContext filterContext)
{
if (filterContext.Exception.GetType() == typeof(System.ArgumentException))
{
//This simply surpresses MVC from raising exception
filterContext.ExceptionHandled = true;
//Some logic to create a default "SettingsRoot" parameter
filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary
{
{ "controller", "Default" },
{ "action", "MyActionMethod" },
{ "settings", new SettingsRoot() }
});
}
}
