How can I make a Response.Redirect() in a class constructor?
public class FarmaciaController : Controller{
public FarmaciaController(){
if(!userLogin.usuarioTemPermissao("Farmacia"))
Response.Redirect("~/PortalFarmacia/Home");
}
}
Redirecting in the constructor may give some problems because of the context as well as not being a good practice, one solution is to create a custom attribute for your action and override the OnActionExecuting method to do the validation.
public class ValidarPermissaoActionAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
base.OnActionExecuting(filterContext);
if (/* verificar se o usuario tem permissão */)
{
filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new
{
controller = "PortalFarmacia",
action = "Home"
}));
}
}
}
And on your Controller
public class FarmaciaController : Controller
{
[ValidarPermissaoAction]
public ActionResult Index()
{
// Essa action só vai ser executada se a validação tiver ok
return View();
}
}
