ASP.NET MVC - 会话为null [英] ASP.NET MVC - Session is null

问题描述

我有它的会话在开发环境中工作，而不是在生产上一个.NET4应用MVC3。结果
在生产记录我的SessionID和它的那一刻我和设置从会话获取相同的。结果
当我试图让我越来越空异常会话。结果
这是我访问会话：

I have an MVC3 application on .net4 that its session working in the dev Environment, but not in the production.
In the production I logged the sessionID and the it is the same in the moment I Set and Get from the session.
When I try to get the session I am getting Null Exception.
This is how I access the session:

public static class HandlersHttpStorage
{
    public static string TestSession
    {
        get
        {
            return HttpContext.Current.Session["time"];//This is null
        }
        set
        {
            HttpContext.Current.Session.Add("time", value);//DateTime.Now.ToString()
        }
    }
}

什么是令我担心的是，在生产的行为比发展的不同，即使在web.config是一样的。

What's makes me worried is that the behavior in the production is different than the development, even though the web.config is the same.

感谢

明白了。很愚蠢，其实。它的工作后我删除和放大器;添加SessionStateModule像这样：

Got it. Quite stupid, actually. It worked after I removed & added the SessionStateModule like so:

<configuration>
  ...
  <system.webServer>
    ...
    <modules>
      <remove name="Session" />
      <add name="Session" type="System.Web.SessionState.SessionStateModule"/>
      ...
    </modules>
  </system.webServer>
</configuration>

简单地增加，因为会话它不会工作应该已经定义的的machine.config 。

现在，我不知道这是做平常的事情。它肯定似乎不那么因为看起来那么粗...

Now, I wonder if that is the usual thing to do. It surely doesn't seem so since it seems so crude...

sessionKey可能会改变，你可能只需要做的：

sessionKey may be changing, you probably only need to do:

HttpContext.Current.Session["CurrentUser"]

或会话可能会过期，检查超时：

Or the session may be expiring, check the timeout:

或者你也可以从别的地方设置会话值，通常我控制通过一个属性访问会话/上下文对象

Or you may be setting the session value from somewhere else, normally i control access to Session/Context object through one property

static readonly string SESSION_CurrentUser = "CurrentUser";

public static SiteUser Create() {     
 SiteUser.Current = new SiteUser();      
 return SiteUser.Current;
}

public static SiteUser Current {     
 get {         
  if (HttpContext.Current.Session == null || HttpContext.Current.Session[SESSION_CurrentUser] == null) {             
   throw new SiteUserAutorizationExeption();         
  }          
  return HttpContext.Current.Session[SESSION_CurrentUser] as SiteUser;     
 } 
 set {
  if (!HttpContext.Current.Session == null) {
   HttpContext.Current.Session[SESSION_CurrentUser] = value;
  }
 }
}
