OBS_CANNED_ACL_PRIVATE

Private read and write. A bucket or object can only be accessed by its owner.

OBS_CANNED_ACL_PUBLIC_READ

public-read

Public read and private write. If this permission is granted for a bucket, anyone can read the object list, multipart uploads, bucket metadata, and object versions in the bucket. If this permission is granted for an object, everyone can obtain the content and metadata of the object.

OBS_CANNED_ACL_PUBLIC_READ_WRITE

public-read-write

Public read and write. If this permission is granted for a bucket, everyone can read the object list, multipart uploads, and bucket metadata, and can upload or delete objects, initiate multipart uploads, upload parts, assemble parts, copy parts, and abort multipart uploads. If this permission is granted for an object, everyone can obtain the content and metadata of the object.

OBS_CANNED_ACL_BUCKET_OWNER_FULL_CONTROL

bucket-owner-full-control

If this permission is granted for an object, only the bucket and object owners have the full control over the object. By default, if you upload an object to a bucket of any other user, the bucket owner does not have the permissions on your object. After you grant this permission to the bucket owner, the bucket owner can have full control over your object. For example, if user A uploads object x to user B's bucket, user B does not have the control over object x. If user A sets bucket-owner-full-control for object x, user B then has the control over object x. This permission is supported only by S3 APIs.

OBS_CANNED_ACL_PUBLIC_READ_WRITE_DELIVERED
