PUT Object acl

Terakhir diperbarui:2024-06-12 15:10:38

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.
