在中間件中設置Slim容器

Question

如何在中間件內的Slim容器中設置某些東西？以下是我的嘗試。

$app = new \Slim\App(); // Using Slim 3.0 

$app->add(function ($request, $response, $next) { 
    $this->logger->addInfo('$this'.print_r($this,1)); //This works, so I can access the container 
    $this->app->getContainer()['xxx']='yyy'; 
    $next->getContainer()['foo']='bar'; 
    $this->bla=123; 
    $this->logger->addInfo('$this'.print_r($this,1)); 
    $response = $next($request, $response); 
    return $response; 
}); 

$container = $app->getContainer(); 

$container['logger'] = function() { 
    $logger = new \Monolog\Logger('my_logger'); 
    $file_handler = new \Monolog\Handler\StreamHandler("../logs/app.log"); 
    $logger->pushHandler($file_handler); 
    return $logger; 
}; 

Answer 1

$this->app->getContainer()['xxx']='yyy'; 

應該是

$this['xxx'] = 'yyy'; 

隨着容器被結合到調用。
