问题描述
我有一个包含现有文件的当前S3存储桶.
I have a current S3 bucket with existing files.
该存储桶最初是一个公共存储桶，我将其权限更改为私有，但是我已经具有上载的对象，并且具有public read CannedACL权限.
The bucket was originally a public bucket, I changed its permissions to be private, but I already have objects that were uploaded and have public read CannedACL permissions.
如何将所有已上传对象的权限更改为私有CannedACL?
How do I change the permissions on all of the uploaded objects to private CannedACL?
