C＃ASP.NET MVC路由-具有特定后缀的所有控制器的路由

Question

I have several controllers for widgets named {WidgetName}WidgetController, eg SampleWidgetController. I need to create a route which catches all requests to such controllers and passes them to one common controller together with requested controller's name and action.

public class SampleWidgetController : Controller
{
    public ActionResult Content()
    {
        ...
    }
}

public class CommonController : Controller
{
    public ActionResult Content(string controllerName, string actionName)
    {
        // I want all requests to SampleWidget/Content to be passed here
        // With controllerName = "SampleWidget" and actionName = "Content"
    }
}

I can create a custom RouteConstraint to accept only those controllers that have 'Widget' suffix, but I have a problem with defining the route itself which will pass the requested controller's name and action to the common controller.

Answer 1

In your RouteConfig RegisterRoutes method add the following route before the default:

routes.MapRoute("Widgets", "{controllerName}Widget/{actionName}",
            new { controller = "Common", action="Content"});

This will cause incoming requests matching the format you've specified, eg [baseurl]/testWidget/testaction would hit your CommonController Content Action with a controllerName="test" and actionName="testaction"

If needed you can then append the "Widget" back onto the controllerName variable and pass it into your desired handler / do what you're trying to do.
