Cookies are not saved in my MVC 5 project

Question

User206383436 posted

I am about to get crazy because I cannot save cookies. I have been dealing with this issue for 10 days and I have also watched a lot of support posts but none of them has the key to solve my issue. I am writing an ASP.NET MVC 5 application with VS2017. The code to read and save cookies is as follows. The Utilerias.NuevoEventoSistema method inserts a line in a text/log file and I always get "The cookie does not exist".

public ActionResult RegistraVoto(String id)
{
    ObtenerCookies();
    return View();
}

private String ObtenerCookies()
{
    String strUserId = "";
            
    if (Request.Cookies["ccIdusuario"] != null)
    {
        Utilerias.NuevoEventoSistema("1. Cookie exists.", "", "", "", "");
        HttpCookie UserIdCookie = Request.Cookies["ccIdusuario"];
        strUserId = UserIdCookie.Value.ToString();
        Utilerias.NuevoEventoSistema("3. Valor de la cookie", strUserId, "", "", "");
    }
    else
    {
        strUserId = Guid.NewGuid().ToString();
        Utilerias.NuevoEventoSistema("1. Cookie does not exist.", "", "", "", "");
        HttpCookie UserCookie = new HttpCookie("ccIdusuario");
        UserCookie.Value = strUserId;
        UserCookie.Expires = DateTime.Now.AddYears(1);
        Response.Cookies.Add(UserCookie);
        Utilerias.NuevoEventoSistema("4. Valor de cookie", strUserId, "", "", "");
    }

    return strUserId;
}

The RegistraVoto controller is called from a View as follos:

<script type="text/javascript">

    function RegistraVoto(id, puntos) {
        var parametro = String(puntos) + '-' + String(id);
        var strURL = encodeURI("/ListasPopularidad/RegistraVoto/" + parametro);

        // Issue POST to server.
        $.post(strURL, {
        }, function (data) {
            alert(data);
        });
    }

</script>

I have tested in Chrome and FireFox with the same result. I have made sure cookies are enabled too. I am running the project directly in VS2017 in localhost.

I will very much appreciate any help that drives me to fix my issue.

P.D.: I implementd this same ObtenerCookies() method in a web forms website without any problem. I wonder if there is a special consideration for MVC. Or maybe the JavaScript code above has something to do.

Hi JORGEMAL ,

You are using ajax to server side function to set the session value , so just use the JsonResult :

public JsonResult RegistraVoto(String id)  
        {  
            var strID=ObtenerCookies();
  
            return Json(strID, JsonRequestBehavior.AllowGet);  
        }  

Return view in your code will initialize the page and not return the response .
