Session 值返回 null 在 mvc5 asp.net

Question

我已經登錄 controller 並在此我得到我的 session 值

[HttpPost]
        public ActionResult Login(Models.AdminUsers adminUsers)
        {
            try
            {
                if (Session["iUserId"] != null || GetCookie("iUserId") != null)
                {
                    return Redirect("/Home/Index");
                }

                if (ModelState.IsValid)
                {
                    using (Data.DataClassesDataContext dc = new Data.DataClassesDataContext())
                    {
                        var resultUsers =
                            (from tableAdminUsers in dc.AdminUsers
                             where
                                tableAdminUsers.cEmail == adminUsers.cEmail &&
                                tableAdminUsers.cPassaword == new Class.AesCryption().Encryption(adminUsers.cPassaword) &&
                                tableAdminUsers.iActive == 1
                             select new Models.AdminUsers
                             {
                                 iUserId = tableAdminUsers.iUserId,
                                 cEmail = tableAdminUsers.cEmail,
                                 cUserName = tableAdminUsers.cUserName,
                                 cUserSurname = tableAdminUsers.cUserSurname,
                                 cImage = tableAdminUsers.cImage
                             }).FirstOrDefault();

                        if (resultUsers != null)
                        {
                            if (adminUsers.lBeniHatirla == false)
                            {
                                Session.Add("iUserId", resultUsers.iUserId);
                                Session.Add("cEmail", resultUsers.cEmail);
                                Session.Add("cUserName", new Class.TextLowerAndFirstUpper().Send(resultUsers.cUserName));
                                Session.Add("cUserSurname", resultUsers.cUserSurname.ToUpper());
                                Session.Add("cImage", resultUsers.cImage);
                            }
                            else
                            {
                                CreateCookie("iUserId", resultUsers.iUserId.ToString());
                                CreateCookie("cEmail", resultUsers.cEmail);
                                CreateCookie("cUserName", new Class.TextLowerAndFirstUpper().Send(resultUsers.cUserName));
                                CreateCookie("cUserSurname", resultUsers.cUserSurname.ToUpper());
                                CreateCookie("cImage", resultUsers.cImage);


                            }

                            return Redirect("/Home/Index");
                        }
                        else
                        {
                            ViewBag.iSonuc = -7;
                        }
                    }
                }
                else
                {
                    ViewBag.iSonuc = -6;
                }
            }
            catch (Exception Ex)
            {
                new Class.Log().Hata("AdminUsers", "AdminUsers_Post", Ex.Message);
            }

            return View();
        }

我想在另一個 controller 中控制到 session 但我的 session 值返回 Z37A6259CC0C19DAE0BD99。 我的控制是這樣的：

if (Session["iUserId"] == null && GetCookie("iUserId") == null)
        {
            return Redirect("/AdminUsers/Login");
        }

        int iUserLogin = 0;
        if (Session["iUserId"] != null && Convert.ToInt32(Session["iUserId"]) > 0)
        {
            iUserLogin = Convert.ToInt32(Session["iUserId"]);
        }
        else if (GetCookie("iUserId") != null && Convert.ToInt32(GetCookie("iUserId")) > 0)
        {
            iUserLogin = Convert.ToInt32(GetCookie("iUserId"));
        }

if (Session["iUserId"] == null && GetCookie("iUserId") == null) 此行返回 true 並再次重定向到登錄頁面。但是我正確獲取 cookie 為什么 session 值返回 Z37A6259CC0C1DAE029CC0C1DAE09？

我在哪里犯錯？ 你能幫助我嗎？

Answer 1

如果是 .net 內核，使用 httpcontext。 您可以使用諸如 Redis 之類的分發緩存來解決它。 https://docs.microsoft.com/tr-tr/aspnet/core/fundamentals/app-state?view=aspnetcore-5.0

如果要開發用戶管理器，請使用三十部分nuget ，例如 Jwt 。 它的作用是 sso 邏輯為您使用它的用戶提供一個令牌

Answer 2

嘗試將 Session 與 HttpContext 一起使用，如下所示：-

HttpContext.Current.Session["iUserId"]=value;

或者，您可以嘗試使用 TempData 而不是 Session。

TempData["iUserId"]=value;

Answer 3

There is a localization function that I use for language change, in this function I am changing the value of the culture using thread, I realized that this function resets my session value.
