DefaultObjectAccessControls

The DefaultObjectAccessControls resources represent the Access Control Lists (ACLs) applied to a new object within Cloud Storage when no ACL was provided for that object. ACLs let you specify who has access to your data and to what extent.

Important:The methods for this resource fail with a 400 Bad Request response for buckets with uniform bucket-level access enabled. Use storage.buckets.getIamPolicy and storage.buckets.setIamPolicy to control access instead.

There are two roles that can be assigned to an entity:

READER s can get an object, though the acl property will not be revealed.
OWNER s are READER s, and they can get the acl property, update an object, and call all objectAccessControls methods on the object.

For more information, see Access Control , with the caveat that this API uses READER and OWNER instead of READ and FULL_CONTROL .

To try out the methods for this resource, see Methods .

get: Returns the default object ACL entry for the specified entity on the specified bucket .
insert: Creates a new default object ACL entry on the specified bucket .
