Należy również zauważyć, że błędy, które nie ustawiają kodu błędu http na 500

(np. nieautoryzowany dostęp)

Nie będzie obsługiwane przez filtr HandleError.

Atrybuty w MVC są bardzo przydatne w obsłudze błędów w metodzie get i post, śledzi również dla wywołania ajax .

Utwórz podstawowy kontroler w swojej aplikacji i Dziedzicz go w głównym kontrolerze (EmployeeController).

Public class EmployeeController : BaseController

Dodaj poniższy kod w kontrolerze bazowym.

/// <summary>
/// Base Controller
/// </summary>
public class BaseController : Controller

Track AJAX Error:

Wywołanie funkcji CheckAJAXError w ładowaniu strony układu.

function CheckAJAXError() {
    $(document).ajaxError(function (event, jqXHR, ajaxSettings, thrownError) {

        var ex;
        if (String(thrownError).toUpperCase() == "LOGIN") {
            var url = '@Url.Action("Login", "Login")';
            window.location = url;
        }
        else if (String(jqXHR.responseText).toUpperCase().indexOf("THE DELETE STATEMENT CONFLICTED WITH THE REFERENCE CONSTRAINT") >= 0) {

            toastr.error('ReferanceExistMessage');
        }
        else if (String(thrownError).toUpperCase() == "INTERNAL SERVER ERROR") {
            ex = ajaxSettings.url;
            //var url = '@Url.Action("ErrorLog", "Home")?exurl=' + ex;
            var url = '@Url.Action("ErrorLog", "Home")';
            window.location = url;
        }

Rozwiązanie dla kodu błędu http do 500 jest to atrybut o nazwie [ERROR] put it on an action

public class Error: System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(System.Web.Mvc.ExceptionContext filterContext)
    {

            if (filterContext.HttpContext.IsCustomErrorEnabled)
            {
                filterContext.ExceptionHandled = true;

            }
            base.OnException(filterContext);
            //OVERRIDE THE 500 ERROR  
           filterContext.HttpContext.Response.StatusCode = 200;
    }

    private static void RaiseErrorSignal(Exception e)
    {
        var context = HttpContext.Current;
      // using.Elmah.ErrorSignal.FromContext(context).Raise(e, context);
    } 

}

/ / przykład:

[Error]

Brakuje Ci błędu.aspx :) w preview 5 znajduje się to w Twoim folderze Views / Shared. Wystarczy skopiować go z nowego projektu Preview 5.
