Slim与Phalcon在API开发中的最佳实践

$app->add(function ($request, $response, $next) {
    $token = $request->getHeader('Authorization');

    if (empty($token)) {
        return $response->withStatus(401);
    }

    if (!isValidToken($token)) {
        return $response->withStatus(403);
    }

    $response = $next($request, $response);

    return $response->withHeader('Authorization', $token);
});

$app->post('/api/v1/users', 'UserController:create');
$app->get('/api/v1/users/{id}', 'UserController:get');

$container = $app->getContainer();
$container['db'] = function () {
    return new PDO(...);
};

// 模型
class User extends \Phalcon\Mvc\Model
{
    public $name;
    public $email;
}

// 控制器
class UserController extends \Phalcon\Mvc\Controller
{
    public function createAction()
    { ... }

    public function getAction()
    { ... }
}

// 视图
<h1>{{ user.name }}</h1>
<p>{{ user.email }}</p>

/**
 * @Route('/api/v1/users')
 */
class UserController extends \Phalcon\Mvc\Controller
{
    /**
     * @Post()
     * @Route('')
     */
    public function createAction()
    { ... }

    ...
}

$di = new \Phalcon\Di\FactoryDefault();
$di->set('db', function () {
    return new PDO(...);
});
