Session变量仍然是两个不同的控制器之间的空 [英] Session variable still remains null between two different controllers

问题描述

我有一个问题，我的MVC项目！的目标是建立一个会话变种，以便将它传递给所有控制器：
我xUserController里面，

I have a problem with my MVC project! The goal is to set a session var in order to pass it to all the controllers: inside my xUserController,

            Session["UserId"] = 52;
            Session.Timeout = 30;

            string SessionUserId = ((Session != null) && (Session["UserId"] != null)) ? Session["UserId"].ToString() : ""; 

// SessionUserId =52

//SessionUserId ="52"

但ChatMessageController内

But within the ChatMessageController

[HttpPost]
public ActionResult AddMessageToConference(int? id,ChatMessageModels _model){

        var response = new NzilameetingResponse();
        string SessionUserId = ((Session != null) && (Session["UserId"] != null)) ? Session["UserId"].ToString() : "";
//...

        }
        return Json(response, "text/json", JsonRequestBehavior.AllowGet);
}

SessionUserId =

SessionUserId = ""

那么，为什么这样？如何设置会话变量是我的所有控制器??

So, Why this ? How to set the session variable to be global within all my controllers ??

推荐答案

下面是我如何解决这个问题。

Here is how I solved the issue

我知道这是不是做的最好方式，但它帮助我：

I know this is not the best way to do it but it helped me:

首先，我创建了一个基本的控制器如下：

First I have created a base controller as follows

public class BaseController : Controller
{
    private static HttpSessionStateBase _mysession;
    internal protected static HttpSessionStateBase MySession {
        get { return _mysession; }
        set { _mysession = value; } 
    }
}

然后，我改变了我的所有控制器'codeS在其他让他们从基础类继承。

then I changed all my controllers' codes in other to let them inherit from the Base Controller class.

然后我重写了OnActionExecuting的方法如下：

Then I overrode the "OnActionExecuting" method as below :

public class xUserController : BaseController
{
    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        BaseController.MySession = Session;
        base.OnActionExecuting(filterContext);
    }
    [HttpPost]
    public ActionResult LogIn(FormCollection form)
    {
        //---KillFormerSession();
        var response = new NzilameetingResponse();
        Session["UserId"] = /*entity.Id_User*/_model.Id_User;
        return Json(response, "text/json", JsonRequestBehavior.AllowGet);
    }
}

最后，我已经改变了我称之为会话变量的方式。

Finally, I've changed the way I call session variables.

string SessionUserId = ((BaseController.MySession != null) && (BaseController.MySession["UserId"] != null)) ? BaseController.MySession["UserId"].ToString() : "";

而不是

 string SessionUserId = ((Session != null) && (Session["UserId"] != null)) ? Session["UserId"].ToString() : "";

现在的作品，我的会话增值经销商可以在所有控制器走路。

now it works and my session vars can walk across all controllers.
