Add new selector in apigility

APIGility is a PHP library that provides a simple way to create RESTful APIs. To add a new selector in APIGility, you can follow these steps:

Step 1: Create a new selector class

Create a new PHP class that will serve as the selector. This class should extend the Zend\Apigility\Rest\Selector class. For example, let's create a new selector called MySelector:

namespace MyNamespace;

use Zend\Apigility\Rest\Selector;

class MySelector extends Selector
{
    // Your selector logic goes here
}

Step 2: Define the selector's methods

In your selector class, you need to define the methods that will be used to handle the API requests. These methods should be named after the HTTP methods you want to support (e.g., get, post, put, delete).

For example, let's add a get method to our MySelector class:

public function get($params)
{
    // Your get logic goes here
    return ['message' => 'Hello, World!'];
}

Step 3: Register the selector with APIGility

To use your new selector with APIGility, you need to register it with the APIGility module. You can do this by creating a new configuration file (e.g., module.config.php) and adding the following code:

return [
    'apigility' => [
        'selectors' => [
            'my_selector' => MyNamespace\MySelector::class,
        ],
    ],
];

Step 4: Configure the API route

Finally, you need to configure the API route to use your new selector. You can do this by adding a new route to your module.config.php file:

return [
    'router' => [
        'routes' => [
            'my-api' => [
                'type' => 'literal',
                'options' => [
                    'route'    => '/my-api',
                    'defaults' => [
                        '__NAMESPACE__' => 'MyNamespace',
                        'controller' => 'MyController',
                        'action'     => 'index',
                    ],
                ],
                'may_terminate' => true,
                'child_routes' => [
                    'my_selector' => [
                        'type' => 'literal',
                        'options' => [
                            'route'    => '/my-selector',
                            'defaults' => [
                                '__NAMESPACE__' => 'MyNamespace',
                                'controller' => 'MyController',
                                'action'     => 'mySelector',
                            ],
                        ],
                    ],
                ],
            ],
        ],
    ],
];

In this example, we've created a new route called my-api that maps to the MyController controller and the index action. We've also added a child route called my_selector that maps to the mySelector action and uses our new MySelector class.

That's it! With these steps, you should now have a new selector in APIGility that you can use to handle API requests.
