  HandleUnauthorizedRequest vs OnActionExecuting

  Mar 01, 2019 04:13 AM|neoaguil17|LINK

  Hi

  I overwrite both methods, but.. What is the first method executed by ASP MVC.

  This is my code:

   public class AccessAttribute : ActionFilterAttribute
      {
          public string Permiso { get; set; }
  
          public override void OnActionExecuting(ActionExecutingContext filterContext)
          {
              if (!FacadeSession.ValidarPermiso(Permiso))
              {
                  if (filterContext.HttpContext.Request.IsAjaxRequest())
                  {
                      filterContext.HttpContext.Response.Clear();
                      filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.Forbidden;
                      filterContext.Result = new JsonResult()
                      {
                          Data = new { status = (int)HttpStatusCode.Forbidden },
                          JsonRequestBehavior = JsonRequestBehavior.AllowGet
                      };
                  }
                  else
                  {
                      filterContext.Result = new RedirectToRouteResult(
                          new RouteValueDictionary {
                          { "action", "PrivilegiosInsuficientes" },
                          { "controller", "AccesoDenegado" },
                      });
                  }                
              }
          }
      }
  
   public class RepAuthorizationAttribute : AuthorizeAttribute
      {
          private RedirectToRouteResult RedirectoToUnauthorizedPageResult = new RedirectToRouteResult(new RouteValueDictionary {
                  { "action", "index" },
                  { "controller", "AccesoDenegado" }
              });
  
          protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
          {            
              if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
              {
                  var result = RedirectoToUnauthorizedPageResult;
                  var errorMsg = ResMessages.ContenidoErrorAutenticacion_RequiereAutenticarse;
                  if (FacadeSession.Usuario != null)
                  {
                      result.RouteValues["action"] = "SesionExpirada";
                      errorMsg = ResMessages.ContenidoErrorAutenticacion_SesionCulminada;
                  }                                       
                  FacadeSession.ClearCookie();
                  filterContext.HttpContext.Response.Clear();                
                  if (filterContext.HttpContext.Request.IsAjaxRequest())
                  {                    
                      filterContext.Result = new JsonResult()
                      {
                          Data = new
                          {
                              status = (int)HttpStatusCode.Unauthorized,
                              errMsg = errorMsg
                          },
                          JsonRequestBehavior = JsonRequestBehavior.AllowGet
                      };
                      filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.Conflict;
                      filterContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;
                  }
                  else
                      filterContext.Result = result;
              }
          }
      }

  Hi neoaguil17,

  Do you mean which method do you enter first?

  According to your code,I put  [RepAuthorization(Roles = "Admin")] and [Access] on one action.

  HandleUnauthorizedRequest is executed first than OnActionExecuting in my demo.

  I suggest you could add breakpoints on your code and check these filter.

  Best Regards.
