What is the difference between REST and RESTful?

  • 772

I understand that they are architectures and that the idea of ​​these is once the web page is downloaded, it does not download any HTML or CSS or JS again, if not, it only makes calls or requests and is answered with JSON

json

    REST (Representational State Transfer) is an architecture that runs on top of HTTP.

    RESTful refers to a web service that implements the REST architecture.

    In a fairly basic example (of creating a RESTful application), we have a project where we implement a CRUD for houses in PHP and with the MVC architecture, the result of the responses will be returned in JSON, but it is not mandatory to handle only that type Content-type, it is can return HTML, text, etc...

    My model would be something like:

    namespace modelos\Casa;

use common\Model;

class Casa extends Model
{

    public function getId($id)
    {
        // Carga una casa por ID
        return ['id' => 1, 'puertas' => 1, 'focos' => 5];
    }

    public function getAll()
    {
        // Carga DB y devuelve todas las casas
        return [
            ['id' => 1, 'puertas' => 1, 'focos' => 5],
            ['id' => 2, 'puertas' => 1, 'focos' => 3],
            ['id' => 3, 'puertas' => 2, 'focos' => 8]
        ];
    }

    public function delete($id)
    {
        // Elimina un registro en la DB
        return parent::delete($id);
    }

    public function save()
    {
        // Valida que todo sea correcto y devuelve un booleano
        return parent::save();
    }

}

    My controller something like:

    namespace controladores\Casas;

use modelos\Casa;
use common\Controller;

header('Content-Type: application/json');

class Casas extends Controller
{

    public function actionPost($id)
    {
        $casa = Casa::findId($id);
        $casa->loadParams($_POST);

        echo json_encode(['success' => $casa->save()]);
    }

    public function actionGet($id = null)
    {
        if (isset($id)) {
            echo json_encode(Casa::getId($id));
        } else {
            echo json_encode(Casa::getAll());
        }
    }

    /* Aquí el demás código */

}

    the 3rd part you could handle it with JavaScript and HTML, where the Js would send the request through AJAX to obtain a result and show it to the user in a friendly way.

    The requests could be made to the resources listed below with the corresponding HTTP status and the controller would be in charge of responding to each one of them.

  2. REST (Representational State Transfer or Representational State Transfer) is a style of software architecture, which not only consists of responding to json, but can also respond to another data exchange format such as xml.

    But aside from just responding in an exchange format other than HTML, REST involves other concepts like:

    • Resources which can be accessed using a global identifier (URI)
    • Well-defined operations to create, read, update, and delete
    • Work under a stateless client-server protocol, such as HTTP, which means that each HTTP message contains all the information necessary to understand the request.

    REST is much more than what I just mentioned, so it would be good if you read a little more about what REST really is and not be left alone with the idea that REST is only for responding to JSON requests.

    RESTful is often used to refer to web services that run the REST architecture.

  3. REST is an "architectural style" that basically takes advantage of existing Web technology and protocols.

    RESTful is often used to refer to the running web services of such an architecture.
