  if (err) console.log(err, err.stack); // an error occurred

推荐答案

您可以使用节点sdk并执行以下操作

You can use node sdk and perform below operations

1. 在文件夹上使用listObject操作.

1. use listObject action on your folder.

浏览该文件夹返回的所有对象，并检查上次修改日期.

Loop through all the object returned for that folder and check last modified date.

如果对象过期，则将对象键添加到数组中.

If object is expired add object key to an array.

删除过期数组中的所有对象

Delete all the object in expired array
