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();
}
}

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; }
}

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:

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.
