Php Slim框架与自动组路由

我想将所有逻辑移到控制器中，如下所示： index.php文件：

$app = new Slim\App();
$app->group('/api/v1', function (\Slim\App $app) {
    $app->group('/users', UsersController::class );
});

class UsersController
{
    public function __construct(\Slim\App $app)
    {
        $app->getContainer()->get('db');

        $app->map(['GET'], '/', [$this, 'readAll']);
        $app->map(['POST'], '/', [$this, 'create']); //Create a new
        $app->map(['PUT'], '/', [$this, 'updateAll']);
        $app->map(['DELETE'], '/', [$this, 'deleteAll']);

        $app->map(['GET'], '/{id}', [$this, 'read']);
        //$app->map(['POST'], '/{id}', [$this, 'createNot']); //Method not allowed (405)
        $app->map(['PUT'], '/{id}', [$this, 'update']);
        $app->map(['DELETE'], '/{id}', [$this, 'delete']);
    }

    ...

}

UsersController.php文件：

$app = new Slim\App();
$app->group('/api/v1', function (\Slim\App $app) {
    $app->group('/users', UsersController::class );
});

class UsersController
{
    public function __construct(\Slim\App $app)
    {
        $app->getContainer()->get('db');

        $app->map(['GET'], '/', [$this, 'readAll']);
        $app->map(['POST'], '/', [$this, 'create']); //Create a new
        $app->map(['PUT'], '/', [$this, 'updateAll']);
        $app->map(['DELETE'], '/', [$this, 'deleteAll']);

        $app->map(['GET'], '/{id}', [$this, 'read']);
        //$app->map(['POST'], '/{id}', [$this, 'createNot']); //Method not allowed (405)
        $app->map(['PUT'], '/{id}', [$this, 'update']);
        $app->map(['DELETE'], '/{id}', [$this, 'delete']);
    }

    ...

}

但我总是犯错误：

传递给UsersController:：\uu构造（）的参数1必须是 Slim\App实例，给定Slim\Container实例

---

如何工作？

当控制器未在容器中注册时，默认情况下，Slim会尝试自行创建控制器，并将容器实例传递给构造函数。但因为您键入了提示，控制器构造函数期望

Slim\App

实例，所以您得到了错误

但我认为你们需要的是一条像这样的路线

$app->group('/app/v1', function () use ($app) {
   $app->group('/users', function () use ($app) {
      $app->get('/', UsersController::class . ':readAll');
      $app->post('/', UsersController::class . ':create');
      $app->put('/', UsersController::class . ':updateAll');
      $app->delete('/', UsersController::class . ':deleteAll');

      $app->get('/{id}', UsersController::class . ':read');
      $app->put('/{id}', UsersController::class . ':update');
      $app->delete('/{id}', UsersController::class . ':delete');
   });
});

所以不再需要在控制器构造函数中设置路由

但是，如果您仍然想按照现在的方式进行，那么您需要在容器中注册控制器

$container[UsersController::class] = function ($c) use($app) {
    return new UsersController($app);
});

就我个人而言，我不建议这样做。

看看这个。它使用slimphp使用MVC概念
