c# - 发布后会话丢失（在开发机器上工作）

Question

我正在开发一个 Holiday Tracker 应用程序，其中一件具体的事情是扼杀整个“页面生命周期”。

在我的用户计划程序中，每个用户都可以插入他的假期，有时它正在工作（因此他可以插入/删除/编辑和查看他的假期）。还有一个假期页面（同样的故事，只是有一个网格）。

但有时设置的会话会丢失。如果我使用 Visual Studio 2012 进行调试，它就可以工作。但是，如果我发布应用程序，它就不起作用。它只是以某种方式迷失了

Global.asax.cs 中的代码

    void Session_Start(object sender, EventArgs e) {
        // Code that runs when a new session is started
        if (HttpContext.Current.User != null && HttpContext.Current.User is HtUser)
        {
            HtUser user = (HtUser)HttpContext.Current.User;
            Session["UserId"] = user.UserId;
            if(user.HtDepartments.Any() && user.HtDepartments.First().HtBusinessUnit != null){
                int BusinessUnitId  = user.HtDepartments.First().HtBusinessUnit.BusinessUnitId;
                Session["BusinessUnitId"] = BusinessUnitId;
            }

        }
    }

我认为可能存在错误。

Answer 1

如果您使用 InProc 会话存储并发布您的应用程序，应用程序池将被 IIS 回收，并且 w3wp.exe 进程会重新生成。然后您的会话数据会立即丢失。

如果这是您遇到的问题，并且您想避免它，则可以选择将会话存储在其他地方（例如在数据库中）。有关详细信息，请参阅有关ASP.NET 会话状态模式的 MSDN 文章。
