php - S3 listObjectsV2 - StartAfter 未显示预期结果

Question

我正在尝试获取存储桶中某个标识符之后的所有文件。

这是我的代码，省略了不相关的部分。

require_once LIB . DS . 'Aws/vendor/autoload.php';
use Aws\S3\S3Client as S3Client;
use Aws\Credentials as Credentials;

$s3 = new S3Client([
        'region'      => $region,
        'version'     => 'latest',
        'key'    => AWS_KEY,
        'secret' => AWS_SECRET,
        'credentials' => $credentials
    ]
);

$data = $s3->listObjectsV2(
                           [
                               'Bucket' => <MY BUCKET>,
                               // the response content should be after this record
                               'StartAfter' => '302760677',
                               'MaxKeys' => 2
                          ]);
print_r($data);

我得到的结果如下:

Aws\Result Object
(
    [data:Aws\Result:private] => Array
        (
            [IsTruncated] => 1
            [Contents] => Array
                (
                    [0] => Array
                        (
                            [Key] => json/300705/300705046/status.json
                            [LastModified] => Aws\Api\DateTimeResult Object
                                (
                                    [date] => 2018-06-20 11:45:06.000000
                                    [timezone_type] => 2
                                    [timezone] => Z
                                )
                            [ETag] => "2777f5fabc31969108b16cd8459d3b5d"
                            [Size] => 945
                            [StorageClass] => STANDARD
                        )
                    [1] => Array
                        (
                            [Key] => json/300705/300705046/address.json
                            [LastModified] => Aws\Api\DateTimeResult Object
                                (
                                    [date] => 2018-06-20 11:45:06.000000
                                    [timezone_type] => 2
                                    [timezone] => Z
                                )

                            [ETag] => "3fd8ef54a83e93d470f5438079f51345"
                            [Size] => 477
                            [StorageClass] => STANDARD
                        )
                )
        )
)

这里，返回的响应内容显示键的数据 - 300705046，小于我在请求的“StartAfter”节点中指定的数据。

谁能帮我理解我可能做错了什么。

谢谢

StartAfter (docs) 与完整 key 匹配。

例如，您可以尝试使用以下方式请求:

'StartAfter' => 'json/302760/302760677/address.json',
