我如何在ASP.NET MVC中禁用会话状态？ [英] How can I disable session state in ASP.NET MVC?

问题描述

我想有这包括删除尽可能多的平常的HttpModules尽可能和禁用会话状态的一个非常轻便的ASP.NET MVC站点。然而，当我尝试这样做，我得到以下错误：

I would like to have a very lightweight ASP.NET MVC site which includes removing as many of the usual HttpModules as possible and disabling session state. However when I try to do this, I get the following error:

的SessionStateTempDataProvider需要SessionState会启用。

我在web.config中已经禁用会话状态：

I've disabled session state in web.config:

<sessionState mode="Off" />

据我所知，ASP.NET MVC使用会话状态的TempData，但我并不需要/想TempData的 - 我只是想禁用会话状态。救命啊！

I understand that ASP.NET MVC uses session state for TempData, but I don't need/want TempData - I just want to disable session state. Help!

推荐答案

您可以使自己的ControllerFactory和DummyTempDataProvider。事情是这样的：

You could make your own ControllerFactory and DummyTempDataProvider. Something like this:

public class NoSessionControllerFactory : DefaultControllerFactory
{
  protected override IController GetControllerInstance(Type controllerType)
  {
    var controller = base.GetControllerInstance(controllerType);
    ((Controller) controller).TempDataProvider = new DummyTempDataProvider();
    return controller;
  }
}


public class DummyTempDataProvider : ITempDataProvider
{
  public IDictionary<string, object> LoadTempData(ControllerContext controllerContext)
  {
    return new Dictionary<string, object>();
  }

  public void SaveTempData(ControllerContext controllerContext, IDictionary<string, object> values)
  {
  }
}

然后你只需要注册应用程序启动时的控制器工厂 - 如你可以在Global.asax中做到这一点：

And then you would just need to register the controller factory on app startup - e.g. you could do this in global.asax:

ControllerBuilder.Current.SetControllerFactory(new NoSessionControllerFactory());
