Asp.Net MVC Default Route

问题

I have my default route defined like this

routes.MapRoute(
                "Default",                                              // Route name
                "{controller}/{action}/{id}",                           // URL with parameters
                new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
            );

However if the user is logged in when they visit the site (This can happen if they ticked the remember me button last time the logged in) I want them to take a different default route and go straight to the logged in page.

Is this possible in global.asax or will I need to put some logic in my home controller to redirect if logged in?

回答1:

Best to put this in the home controller. A check if authenticated and return the appropriate view.

I want them to take a different default route

Routing in ASP.NET MVC is about routing URLs to action methods on controllers, not about routing users to places in your web site depending on the current circumstances. (Think of routing as a static thing, whereas the rest (authorization, redirection, etc) is only applicable to the current session.)

It is possible to use Routing Constraints to achieve what you want, but I don't think that's what you want.
