Laravel JsonResponse数组获取

有一个JsonResponse数据的格式如下：

object(IlluminateHttpJsonResponse)[474]
  protected 'data' => string '{"code":200,"message":"u6210u529f","data":{"file_name":"b3c8622cc85a5783b6b39e6c998f8c1e.jpg","file_path":"b3/c8/b3c8622cc85a5783b6b39e6c998f8c1e.jpg","file_size":290576,"url":"https://quxuexi-pub.qfq.me/b3/c8/b3c8622cc85a5783b6b39e6c998f8c1e.jpg","original_url":"/tmp/phpUVwzdV"}}' (length=292)
  protected 'callback' => null
  protected 'encodingOptions' => int 0
  public 'headers' => 
    object(SymfonyComponentHttpFoundationResponseHeaderBag)[476]
      protected 'computedCacheControl' => 
        array (size=2)
          'no-cache' => boolean true
          'private' => boolean true
      protected 'cookies' => 
        array (size=0)
          empty
      protected 'headerNames' => 
        array (size=3)
          'cache-control' => string 'Cache-Control' (length=13)
          'date' => string 'Date' (length=4)
          'content-type' => string 'Content-Type' (length=12)
      protected 'headers' => 
        array (size=3)
          'cache-control' => 
            array (size=1)
              ...
          'date' => 
            array (size=1)
              ...
          'content-type' => 
            array (size=1)
              ...
      protected 'cacheControl' => 
        array (size=0)
          empty
  protected 'content' => string '{"code":200,"message":"u6210u529f","data":{"file_name":"b3c8622cc85a5783b6b39e6c998f8c1e.jpg","file_path":"b3/c8/b3c8622cc85a5783b6b39e6c998f8c1e.jpg","file_size":290576,"url":"https://quxuexi-pub.qfq.me/b3/c8/b3c8622cc85a5783b6b39e6c998f8c1e.jpg","original_url":"/tmp/phpUVwzdV"}}' (length=292)
  protected 'version' => string '1.0' (length=3)
  protected 'statusCode' => int 200
  protected 'statusText' => string 'OK' (length=2)
  protected 'charset' => null
  public 'original' => 
    array (size=3)
      'code' => int 200
      'message' => string '鎴愬姛' (length=6)
      'data' => 
        array (size=5)
          'file_name' => string 'b3c8622cc85a5783b6b39e6c998f8c1e.jpg' (length=36)
          'file_path' => string 'b3/c8/b3c8622cc85a5783b6b39e6c998f8c1e.jpg' (length=42)
          'file_size' => int 290576
          'url' => string 'https://quxuexi-pub.qfq.me/b3/c8/b3c8622cc85a5783b6b39e6c998f8c1e.jpg' (length=69)
          'original_url' => string '/tmp/phpUVwzdV' (length=14)
  public 'exception' => null

想要获取其中的data数据，然后就直接：

$result['data'];

最后发现这是不可以的，正确的方法如下：

$jsonArray = $result->getData(true);
