AWS S3 PHP SDK V3如何直接转到存储桶

Question

我一直在尝试学习这个SDK并且我开始理解它，但我似乎无法弄清楚的一个问题是如何直接进入“文件夹”（我知道没有文件夹）在桶中？ 在我的存储桶中，我有“folder1”，使用getIterator（'ListObjects'，...我得到的只是显示“folder1”的存储桶的根，而不是“folder1”的根。 我使用了'Prefix'和'Delimiter'，但我想我错过了一些东西。

我得到了，感谢任何帮助。

$s3 = new S3Client([
'version'     => 'latest',
'region'      => 'us-east-1',
'credentials' => [
    'key'    => $config['s3']['key'],
    'secret' => $config['s3']['secret'],
],]);
        $objects = $s3->getIterator('ListObjects', array(
            'Bucket' => $config['s3']['bucket'],
            'Prefix' => $config['s3']['folder1']."/",
            'Delimiter' => "/",

            ));
                          foreach($objects as $object):...

我在这里缺少什么？
