1。asp.net mvc URL routing
- IIS determines the request should be handled by ASP.NET
- The MvcHandler uses IControllerFactory to obtain an instance of IController using the "controller" route data from the route {controller}/{action}/{id}.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
- The HomeController is found, and its Execute method is invoked
- The HomeController invokes the Index action
- The Index action adds some objects to the ViewData dictionary
return View();
}
- ASP.NET renders the response to the browser.
2.Controller两种形式
