ASP.NET MVC 5 方法 Session_Start 在 IIS 中无法正常工作

Question

我需要将 asp.net mvc 5 应用程序发布到 iis 服务器。 目标框架是 4.7.2。 在 Web.Config 文件中定义了 Windows 身份验证

这是 Web.config 文件

在 iis 服务器中，我禁用了匿名身份验证并启用了 Windows 身份验证。

当我尝试从浏览器启动应用程序时，我收到一个错误，例如用户 'DOMAIN \ MACHINENAME $' 的登录失败

这是我从浏览器收到的堆栈跟踪

奇怪的是，应用程序尝试从本地路径执行 Global.asax 文件中的 Session_Start 方法。 在红色下划线的线中可以看到。

事实上，如果我尝试从 Global.asax 文件中删除 Session_Start 方法，我不会出现此类错误，但此方法中包含的说明对于应用程序的正确运行非常重要。

这是我使用的 Global.asax 文件

public class MvcApplication : System.Web.HttpApplication
    {

        DWH_FATTEntities db = new DWH_FATTEntities();
        utenti utente = new utenti();

        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }

        protected void Session_Start(Object sender, EventArgs e)
        {

            string username = User.Identity.Name.Substring(8);
            utente = db.utenti.Where(i => i.alias == username).FirstOrDefault();

            //Context.Items["listmot"] = new MotMainViewModel();

            if (utente != null && utente.utente_dashboard)
            {
                HttpContext.Current.Session.Add("accesso_utente", utente.utente_dashboard);
                HttpContext.Current.Session.Add("username", username);
                HttpContext.Current.Session.Add("nome_utente", utente.nome);
                HttpContext.Current.Session.Add("cognome_utente", utente.cognome);
                HttpContext.Current.Session.Add("mail_utente", utente.mail);
                HttpContext.Current.Session.Add("gruppo_utente", utente.gruppo);
                HttpContext.Current.Session.Add("responsabile_utente", utente.responsabile);

                GetMot();
            }

        }

        public static void GetMot()
        {
            List<MotMainViewModel> listmot = new List<MotMainViewModel>();

            using (var db = new DWH_FATTEntities())
            {
                listmot = (from mot in db.servizi_new
                           join clienti in db.clienti on mot.id_cliente equals clienti.id_cliente into ps
                           from clienti in ps.DefaultIfEmpty()
                           select new MotMainViewModel
                           {
                               n_ordine = mot.n_ordine,
                               data_ordine = mot.data_ordine,
                               ragione_sociale_cliente = clienti.ragione_sociale,
                               data_consegna = mot.data_consegna,
                               data_cessazione = mot.data_cessazione,
                               note = mot.note,
                               rfc = mot.rfc,
                               ros = mot.ros,
                               id_sito_a = mot.id_sito_a,
                               id_sito_b = mot.id_sito_b,
                               qty = mot.qty,
                               tipo_circuito = mot.tipo_circuito,
                               id_cliente = mot.id_cliente,
                               mercato = mot.mercato,
                               id_gca = mot.id_gca,
                               tipo_contratto = mot.tipo_contratto,
                               data_inserimento = mot.data_inserimento,
                               data_invio_cessazione = mot.data_invio_cessazione,
                               motivo_cessazione = mot.motivo_cessazione
                           }).ToList();
            }

            HttpContext.Current.Session.Add("listmot", listmot);
        }
    }

我究竟做错了什么？

Answer 1

您可以尝试以下设置：

• 在 ApplicationPoolIdentity 下运行的 Web 应用程序
• Web 应用程序通过 ADO.Net 在连接字符串中使用 Windows 身份验证连接到数据库

如果您的数据库连接处于 Windows 身份验证模式。 您需要将应用程序池标识从 ApplicationPoolIdentity 更改为您的域登录凭据 DomainName\YourloginId

步：

1. 单击应用程序池
2. 选择您的应用程序的名称
3. 进入高级设置
4. 展开流程模型并单击身份。 单击右端的三个点。
5. 单击设置...按钮并提供您的域登录凭据

笔记：

在生产或 IT 环境中，您可能在同一域下拥有应用程序池标识的服务帐户。 如果是这样，请使用服务帐户而不是您的登录名。
