    :put-object-acl

    Last Updated:Apr 02, 2025

    The put-object-acl command is used to set or modify the access control list (ACL) of an object.

    Usage notes

    • By default, an Alibaba Cloud account has the permissions to set the ACL of an object. Setting the ACL as a RAM user or by using Security Token Service (STS) requires oss:PutObjectAcl permission. For more information, see Attach a custom policy to a RAM user.

      Only the bucket owner that has permissions to read and write objects in the bucket can call this operation to modify the ACLs of the object.

    • The ACL of an object takes precedence over the ACL of the bucket in which the object is stored. For example, if an object whose ACL is public-read-write is stored in a bucket whose ACL is private, all users can read and write the object.
