How to add REST features to your Cakephp 3 App

Leave a comment

23666To add REST features to your CakePHP 3 you simply need to add two lines of code to your controller;

This will allow any action in the controller to be viewed as JSON or XML .

To view your action index as JSON simply;

http://localhost/mycakeapp/mycontroller/index.json

Rest Examples:
http://localhost/mycakeapp/mycontroller/view/1.json

http://localhost/mycakeapp/mycontroller/view/1.xml

 

public function initialize()
{
parent::initialize();
$this->loadComponent('RequestHandler');
}

 

Then in routes.php file /config/routes.php add;

Router::extensions(['json', 'xml']); //ensure this is before the below line.
Router::scope('/', function (RouteBuilder $routes) {

More info from the manual:
http://book.cakephp.org/3.0/en/development/routing.html#resource-routes

Cakephp Tip #3 – Requesting JSON or XML

Leave a comment

The newest version of Cakephp makes it even easier to make a JSON or XML request.

Add the request handler component to your controller;

public $components = array('Paginator','RequestHandler' );

create your action in your controller;
eg

public function testjson() {
$this->set('posts', $this->paginate());
$this->set('_serialize', array('posts'));
}

To access either the JSON or XML version simply append .json or .xml to the action name;

http://localhost/myapp/posts/testjson.json

http://localhost/myapp/posts/testjson.xml
