如何在.NET MVC 5中存储会话数据 [英] How to store session data in .NET MVC 5

问题描述

我可以使用HttpContext.ApplicationInstance.Context类通过Session函数存储会话数据吗? 还是有更好的方法可以做到这一点?

Can I use the HttpContext.ApplicationInstance.Context class to store session data using the Session function? Or there is a better way to do this?

推荐答案

通常，会话可以作为控制器操作中的属性来使用:

Normally the session is available as a property in your controller actions:

public ActionResult Index()
{
    this.Session["foo"] = "bar";
    return View();
}

由于 Session 属性的类型为HttpSessionStateBase，可以在单元测试中更轻松地对其进行模拟.请不要使用静态HttpContext.Current.Session，如您在其他地方可能会看到的建议.

Since the Session property is of type HttpSessionStateBase it can be more easily mocked in a unit test. Please never use the static HttpContext.Current.Session as you might see suggested elsewhere.

如果您不在控制器动作中，则可以使用其Session属性访问HttpContextBase实例(几乎在MVC管道的每个部分中)，以访问该会话.

If you are not inside a controller action you can access the session if you have an instance of HttpContextBase (which is almost in every part of the MVC pipeline) using its Session property.
