Overview

This API is used to write an access control list (ACL) to an object. You can set the ACL information through the x-cos-acl and x-cos-grant-* request headers or the request body in XML format.

Note：

• You can set the ACL information either through request headers or through the request body.
• PUT Object acl is an overwriting operation. The new ACL will overwrite the old one.
• You can only grant permissions to Tencent Cloud CAM root accounts or anonymous users. To grant permissions to sub-accounts or user groups, please use the PUT Bucket policy API. For more information about ACL, please see ACL Overview.
• To call this API, you need to have permission to write ACL to the object.
