我正在S3之上实现一个文件管理器,目前我正在尝试通过LifeCycles实现无缝冰川归档。LifeCycles的S3方面是非常直接的。但是,我找不到一个方法来返回密钥的实际存储类。它显然是可用的,因为S3控制面板显示了它
在存储类的文档中,他们提到应该存在此元数据对象(S3使用元数据):
x-amz-storage-class用于存储对象的存储类。
headObject文档提到它应该返回元数据,但当我运行它时,没有返回元数据块。

同时,文档声称元数据应该是返回的字段之一:
Metadata => (associative-array<string>)
Associative array of <string> keys mapping to (string) values. Each array key should be changed to an appropriate <string>.
A map of metadata to store with the object in S3.
<string> => (string)
The metadata value.
仅供参考,我正在使用此文档用于PHP 的AWS SDK
任何建议都值得赞赏,因为目前我找到的唯一解决方案是要么运行getObject(这是不可行的,因为它会下载整个对象),要么在每次调用时运行restoreObject并检查其异常代码。但这意味着,在不恢复密钥(如果已存档)的情况下,不可能检查密钥的状态
谢谢。
我能够得到它。当我运行以下代码时:
$s3 = 'Aws'S3'S3Client::factory($config);
$result = $s3->listObjects(array(
'Bucket' => 'somebucket'
));
echo $result;
我得到了这个输出,它包含StorageClass:
