如何重定向到从 Asp.Net MVC 中的全局异常过滤器查看

Question

我正在使用asp.net core处理 MVC，我在其中创建了一个全局过滤器来处理异常。 它处理异常但不重定向到共享文件夹中的视图（Error.cshtml）。

下面是我的代码：

public void OnException(ExceptionContext filterContext)
        {
            if (filterContext.ExceptionHandled)
            {
                return;
            }
            Exception e = filterContext.Exception;
            filterContext.ExceptionHandled = true;
            string action = filterContext.RouteData.Values["action"].ToString();
            string controller = filterContext.RouteData.Values["controller"].ToString();
            filterContext.Result = new ViewResult()
            {
                ViewName = "/Error" // also tried with "Error" and "~/Error"
            };
        }

Answer 1

我希望这对你有用

protected override void OnException(ExceptionContext filterContext)
{
  filterContext.ExceptionHandled = true;

  //Redirect or return a view, but not both.
  filterContext.Result = RedirectToAction("Index", "Home");
  // OR 
  filterContext.Result = new ViewResult
  {
     ViewName = "~/Views/Shared/Error.cshtml"
  };
}

        filterContext.Result = new RedirectToRouteResult(
            new RouteValueDictionary
            {
                { "controller", "Account" },
                { "action", "Index" },
                { "returnUrl", filterContext.HttpContext.Request.RawUrl } 
            });
