在任何Controller之前调用会话在MVC中运行 [英] Calling the Session before any Controller Action is run in MVC

问题描述

我在Session_OnStart（）调用的global.asax文件中进行了此身份验证检查：

I have this authentication check in my global.asax file in the Session_OnStart() call:

if (Session["Authenticated"] == null)
        {
            Response.Redirect("~/Login.aspx");
        }

这种会话认证在我们的所有网络应用程序中紧密耦合，以这种方式使用它。这个global.asax位于一个较旧的Webforms项目，我的MVC项目坐在那里。所以我相信它让我访问我的控制器动作，例如 http：// localhost / controller / action ，而不会填充我的会话身份验证，即不会重定向。我已经添加了这一点的代码到每个控制器动作来绕过这一点，但有一种方法来设置这个地方全局（不是在global.asax），所以我只需要为所有控制器动作调用一次？谢谢。

This kind of session authentication is tightly coupled in all our web apps so I have to use it this way. This global.asax sits in an older Webforms project, which my MVC project is sitting in. So for this reason I believe its letting me access my controller action e.g http://localhost/controller/action directly without my session authentication being populated, i.e its not redirecting. I have added this bit of code to EACH controller action to get around this, but is there a way to set this somewhere globally (not in the global.asax) so that I only have to call it once for all controller actions? Thanks.

推荐答案

您应该创建一个所有控制器继承的basecontroller。那么你只需要在一个地方的逻辑。即：

You should create a basecontroller that all your controllers inherit from. then you simply have the logic in one place. i.e.:

public abstract class BaseController : ControllerBase

你可以在新的BaseContoller中使用initialize方法来做公共逻辑。即

you could then use the initialize method in the new BaseContoller to do the common logic. i.e.

[edit] - 更改为OnActionExecuting，而不是初始化。这不是最优雅的地方，因为我们在被称为视图的尖端​​。

[edit] - changed to OnActionExecuting, rather than Initialize. This isn't the most elegant of places to do it as we're on the cusp of the view being called. however, it's a starting point.

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    // you should be able to get session stuff here!!
    base.OnActionExecuting(filterContext);
}

并在每个控制器中：

public class AnotherNormalController : BaseController
