Example Usage

Simple example for using the authorization middleware.

use Chadicus\Slim\OAuth2\Middleware;
use OAuth2;
use OAuth2\Storage;
use OAuth2\GrantType;
use Slim;

//set up storage for oauth2 server
$storage = new Storage\Memory(
    [
        'client_credentials' => [
            'administrator' => [
                'client_id' => 'administrator',
                'client_secret' => 'password',
                'scope' => 'superUser',
            ],
            'foo-client' => [
                'client_id' => 'foo-client',
                'client_secret' => 'p4ssw0rd',
                'scope' => 'basicUser canViewFoos',
            ],
            'bar-client' => [
                'client_id' => 'foo-client',
                'client_secret' => '!password1',
                'scope' => 'basicUser',
            ],
        ],
    ]
);

// create the oauth2 server
$server = new OAuth2\Server(
    $storage,
    [
        'access_lifetime' => 3600,
    ],
    [
        new GrantType\ClientCredentials($storage),
    ]
);

//create the basic app
$app = new Slim\App();

// create the authorization middlware
$authMiddleware = new Middleware\Authorization($server, $app->getContainer());

//Assumes token endpoints available for creating access tokens

$app->get('foos', function ($request, $response, $args) {
    //return all foos, no scope required
})->add($authMiddleware);

$getRouteCallback = function ($request, $response, $id) {
    //return details for a foo, requires superUser scope OR basicUser with canViewFoos scope
};

$app->get('foos/id', $getRouteCallback)->add($authMiddleware->withRequiredScope(['superUser', ['basicUser', 'canViewFoos']]));

$postRouteCallback = function ($request, $response, $args) {
    //Create a new foo, requires superUser scope
};

$app->post('foos', $postRouteCallback)->add($authMiddleware->withRequiredScope(['superUser']));

$app->run();
