Question

After a user Logs in to the system, i need to put a variable in the Session. I am doing this with an extension method:

Login method:

[HttpPost]
        public ActionResult LogOn(LogOnModel model, string returnUrl)
        {
            if (ModelState.IsValid)
            {
                if (Membership.ValidateUser(model.UserName, model.Password))
                {
                    FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);

                    int id = this.HttpContext.GetFirmaId();
                    String username = this.HttpContext.User.Identity.Name;

                    //SessionExtensions.SetFirmaId(Session, model.UserName);

                    if (Url.IsLocalUrl(returnUrl) && returnUrl.Length > 1 && returnUrl.StartsWith("/")
                        && !returnUrl.StartsWith("//") && !returnUrl.StartsWith("/\\"))
                    {
                        return Redirect(returnUrl);
                    }
                    else
                    {
                        if (User.IsInRole("Administrator"))
                        {
                            RedirectToAction("Index", "Admin");
                        }
                        else
                        {
                            return RedirectToAction("Index", "Home");
                        }
                    }
                }
                else
                {
                    ModelState.AddModelError("", "Brugernavn eller password er forkert.");
                }
            }

            // If we got this far, something failed, redisplay form
            return View(model);
        }

Extension method:

public static int GetFirmaId(this HttpContextBase context)
    {

        var firmaid = context.Session["firmaid"] as int?;

        if (firmaid == null)
        {
            // Hvis firmaid er røget ud af Session, skal den firmaid som tilhører brugeren hentes

            firmaid = SetFirmaId(context.Session, context.User.Identity.Name);

        }

        return (int)firmaid;
    }

The problem is that context.User.Identity.Name returns an empty string.

How can i solve this problem?

Answer 1

try

public static int GetFirmaId(this HttpContextBase context)
        {

            var firmaid = context.Session["firmaid"] as int?;

            if (firmaid == null)
            {
                // Hvis firmaid er røget ud af Session, skal den firmaid som tilhører brugeren hentes

                firmaid = SetFirmaId(context.Session, context.User.Identity.Name);

            }

            return (int)firmaid;
        }

UPDATE – as per comment: use it just like this.HttpContext.GetFirmaId() from your controller.

UPDATE 2 – as per comments:

The problem of being User.Identity.Name has no connection to the question – the answer above is what to do to access it in a class outside of a Controller.

AS the OP saw in the debugger it is even empty inside the controller in this specific case – I suspect that it is being accessed “too early” in the process so that it is indeed empty.

If you need help dealing with AccountController ask a new question.
