It is vital to be aware of the purpose of attributes like HttpPostAttribute. Equivalent attributes are outlined for other HTTP verbs.

You may define the routes and those routes will map URLs to a particular controller action. An action is just a technique over the controller. It might also decide parameters out of that URL and pass them as parameters into the strategy.

The value of controller and action are Section of equally ambient values and values. The strategy Url.Motion generally uses The existing values of motion and controller and generates a URL path that routes to The existing action.

With attribute routing, the controller and motion names Participate in no component wherein motion is matched, Unless of course token replacement is applied. The following illustration matches exactly the same URLs given that the previous instance:

Simplicity of Servicing: As the applying grows, protecting a reliable routing composition will become much easier, particularly when new controllers and actions are added.

Nevertheless if we constructed a MVC internet site for the same, the URL would possibly appear to be ‘hxxp://’ and ‘hxxp://’. By convention (and default) the first URL maps to the ProductController class by having an motion named Index. The next URL maps for the ProductController class with and motion named Particulars. As we can see, MVC Routing will help abstract URLs clear of Bodily documents which by default maps to Controller/Action approach pairs by default. We will now go into particulars of how this mapping happens and the way to modify the defaults. But ahead of that, some ideal methods!  

This allows us to create routes that count only about the URL values without having predetermined or default values. If a route parameter is absent in the URL, It will likely be addressed as lacking.

Traditional routing is buy-dependent. Generally speaking, routes with locations must be put before as They are more particular than routes with no a region.

As we will see, we have outlined a brand new route that expects a group parameter. Now when we provide Electronics for a parameter, we obtain a properly filtered record

Token substitute takes place as the last stage of building the attribute routes. The previous example behaves the same as the following code:

So, employing Default values, we will specify what occurs if parts of the route are not provided during the URL. One example is, once we navigate to the following two URLs

This can be Operating fine. Nevertheless, Imagine if we planned to have additional unique routes? Say one thing like the following URLs:

In case the URL would not include everything once the area identify, then the default controller and motion technique will manage the request. One example is, could well be routing in asp.net mvc handled from the HomeController along with the Index() system as configured during the default parameter.

At present there is not any these types of ‘filter’ offered. Let's implement this. Initial we insert a parameter category to the Index motion strategy, and filter the info we're acquiring through the Database and return it into the perspective.
