PHP列出S3存储桶中文件夹中的对象

我有一个S3存储桶，里面有一堆文件夹。 当我列出其中一个文件夹中的对象时，例如

folder1

，我会得到所有项目，但也会得到列出的文件夹的名称。 我曾尝试使用分隔符，或键标记，但它似乎没有很好的响应

我使用的代码列出了所有对象，还列出了这些对象所在的文件夹名称

$objects = $s3Client->getIterator('ListObjects', array(
        "Bucket" => $bucket,
        "Prefix" => 'folder1/',
        'KeyMarker' => 'folder1/', //don't list folder1/ and start listing after this folder.
    )); 
    foreach ($objects as $object) {
        echo "<li><strong>" . basename($object['Key']) . "</strong> Size: " . $object['Size'] .  " bytes  ";
    }

期望输出：

test.txt Size: 250 bytes
johnpdf.pdf Size: 422 bytes

要实现的代码是

$objects = $s3Client->getIterator('ListObjects', array(
        "Bucket" => $bucket,
        'Marker' => 'folder1/',
        "Prefix" => "folder1/"


        
    )); 
    foreach ($objects as $object) {
        echo "<li><strong>" . $object['Key'] . "</strong> Size: " . $object['Size'] .  " bytes  ";
    }

$objects=$s3Client->getIterator（'ListObjects'，数组(
“桶”=>美元桶，
'标记'=>'文件夹1/'，
“前缀”=>“文件夹1/”
)); 
foreach（$objects作为$object）{
回显“
”$object['Key']”。大小：“.$object['Size']”字节；
}

$objects = $s3Client->getIterator('ListObjects', array(
        "Bucket" => $bucket,
        'Marker' => 'folder1/',
        "Prefix" => "folder1/"


        
    )); 
    foreach ($objects as $object) {
        echo "<li><strong>" . $object['Key'] . "</strong> Size: " . $object['Size'] .  " bytes  ";
    }
