Slim 3: Overriding default response class using DI container

Created on 4 Sep 2015 · 5Comments · Source: slimphp/Slim

I have a class that extends the SlimHttpResponse class and would like to use that with my slim app. I thought I could do that using the DI container but when I inspect the class of the response, it's still just SlimHttpResponse and not my custom class (called ApiResponse).

Example:
$app = new App();
$container = $app->getContainer();
$response = $container->get('response');
var_dump(get_class($container->get('response'))); // doesnt return my custom class

The App class constructor:

public function __construct(SlimContainer $container = null) {

if (!isset($container)) {
  $container = new \Slim\Container(array(
    'response' => new ApiResponse()
  ));
}
parent::__construct($container);

}

I'm not sure if this is a bug or I'm just not using the DI container correctly.....

This works for me:

class ApiRequest extends Slim\Http\Request
{
}

$app = new Slim\App([
    'request' => function ($c) {
        return ApiRequest::createFromEnvironment($c['environment']);
    }
]);

$app->get('/', function ($request, $response, $args) {
    echo get_class($request); // ->  ApiRequest
    return $response;
});

$app->run();

The extended App also is fine for me:

use Slim\App;
use Slim\Container;
use Slim\Http\Request;

require 'vendor/autoload.php';

class ApiRequest extends Request
{
}

class MyApp extends App
{
    public function __construct()
    {
        $container = new Container([
            'request' => function ($c) {
                return ApiRequest::createFromEnvironment($c['environment']);
            }
        ]);

        parent::__construct($container);
    }
}

$app = new MyApp();

$app->get('/', function ($request, $response, $args) {
    echo get_class($request); // ->  ApiRequest
    return $response;
});

$app->run();

@jwyuen you are missing a closure for your new Response class.

if (!isset($container)) {
  $container = new \Slim\Container(array(
    'response' => new ApiResponse()
  ));
}
parent::__construct($container);

should be

if (!isset($container)) {
  $container = new \Slim\Container(array(
    'response' => function () { 
        return new ApiResponse(); 
    }
  ));
}

parent::__construct($container);
