MVC4会话不请求之间仍然存在 [英] MVC4 Session not persisted between requests

问题描述

大更新后，一些很好的测试

我有一个MVC4 Web应用程序，我只是调试它在Visual Studio 2010只是学习一些更多的web开发（和MVC尤其是）。我现在玩会话。但我不明白为什么我一个新的htt prequest后失去我的变量。

I have a MVC4 web application and I'm simply debugging it in visual studio 2010 just to learn some more about webdevelopment (and MVC in particular). I'm playing with Session now. But I don't understand why I lose my variables after a new httprequest.

是这样的问题：失去我的会话变量

我对会议的部分web.config中如下：

My web.config for the session part looks like:

<sessionState mode="InProc"
   cookieless="false"
   timeout="20"/>

我的小测试项目，以找出问题工作正常，看起来像：

My little test project to isolate the problem works fine and looks like:

控制器
- HomeController的

Controllers - HomeController

public class HomeController : Controller
{
    //
    // GET: /Test/

    public ActionResult Index()
    {
        string t = (string)Session["Test1"];
        ViewBag.Result = t;
        return View();
    }

}

• MysessionController

  • MysessionController

    公共类MysessionController：控制器
        {
            //
            // GET：/ MySession的/

    public class MysessionController : Controller { // // GET: /Mysession/

        public ActionResult Index()
        {
            return View(new Models.Mysession() {ID = Session.SessionID});
        }
    
        [HttpPost]
        public ActionResult Index(Models.Mysession mySession) {
            Session["Test1"] = "Bla";
            return RedirectToAction("Index", "Home");
        }
    
    }
    

  
  

  模式

  public class Mysession {
      [Required]
      public string ID { get; set; }
  }

  @using (Html.BeginForm()) {

  @Html.ValidationSummary(false)
  <fieldset>
      <legend>Mysession</legend>
       <div class="editor-label">
          @Html.LabelFor(model => model.ID)
      </div>
      <div class="editor-field">
          @Html.EditorFor(model => model.ID)
      </div>
      <p>
          <input type="submit" value="Log in" />
      </p>
  </fieldset>
  

  }

  这看起来像我的主要应用简单地说，所不同的是：在在会话变量设置存取权限我一个XML文件来查找东西HTTPPOST Index操作MysessionController。

  This looks in a nutshell like my main application, the DIFFERENCE is: In MysessionController in the HTTPPOST Index action where the session variable is set I acces a XML file to look up something.

  XML文件是我的持久化存储，因为我没有一个SQL服务器。我的问题是，这会影响我的会议？

  The XML file is my persistent storage because I don't have a SQL server. My question is, can this affect my session?

  如果是这样，我想指出，我的存取权限的XML文件之前，在会话设置变量。因此，它似乎很奇怪我。但我已经通过测试，如果我没有存取权限的XML文件，然后在会话的增值经销商都很好精确定位。如果我的存取权限XML文件中的会话瓦尔的RedirectToAction后是空的。

  If so, I would like to point out that I acces the XML file PRIOR to setting the variable in the session. So it seems strange to me. But I've pinpointed by testing that if I don't acces the XML file then the vars in the session are fine. If I acces the XML file the vars in the session are null after the RedirectToAction.

  我不知道为什么我昨天没有来到这个结论。对不起大家。我昨天做了一些马虎的测试。

  I don't know why I didn't came to this conclusion yesterday. Sorry everybody. I did some sloppy testing yesterday.

  推荐答案

  首先，我想感谢大家，已经把时间这个问题。之后我得到了自己在一起，最后进行了适当的测试我明确指出这个问题到硬盘驱动器上访问XML文件。不知道是什么我搞乱昨天...

  First off, I would like to thank everybody that has put time in this question. After I got myself together and finally conducted a proper test I pinpointed the problem to accessing a XML file on the hard drive. Don't know what I was messing about yesterday...

  我发现谷歌低谷几个帖子和文章有关访问文件后，失去您的会话。像这样的：

  I found trough Google several posts and articles about losing your session after accessing files. Like this one:

  <一个href=\"http://blogs.msdn.com/b/tess/archive/2006/08/02/asp-net-case-study-lost-session-variables-and-appdomain-recycles.aspx\">http://blogs.msdn.com/b/tess/archive/2006/08/02/asp-net-case-study-lost-session-variables-and-appdomain-recycles.aspx

  由泰莎Ferrandez神奇的案例研究。而对于较小的扩展：

  Fantastic case study by Tessa Ferrandez. And to lesser extend: http://forums.asp.net/t/998370.aspx/1

  和

  结论

  当您在您的网站的任何方式访问文件的应用程序域将被刷新，这将刷新您的会话。

  When you access files in any way of your website the AppDomain will be refreshed and this will refresh your session.

  不要把你需要通过你的网站在你的'bin文件夹访问文件。我搬到我的XML文件的App_Data和变量在会话持久。

  Never put a file you need to access through your website in your 'bin' folder. I've moved my XML file to App_Data and the variables are persisted in the Session.
