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
类来存储使用 Session
函数的会话数据吗?或者有更好的方法来做到这一点?
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
通常会话可作为控制器操作中的属性使用:
Normally the session is available as a property in your controller actions:
public ActionResult Index()
{
this.Session["foo"] = "bar";
return View();
}
由于 Session
属性属于 HttpSessionStateBase
类型,它可以更容易地在单元测试中模拟.请不要使用静态 HttpContext.Current.Session
,因为您可能会在其他地方看到建议.
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.
如果您不在控制器操作中,如果您有一个使用其 Session 属性的 HttpContextBase
实例(几乎在 MVC 管道的每个部分),您就可以访问该会话.
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.
