Through the STS service, RAM users or RAM roles can obtain a temporary token that allows them to call the Alibaba Cloud API or use the web console

A STS request consists of an access address, communication protocol, request method, request parameters and character encoding

When calling the STS API, in order to ensure the safe calling of the API, Alibaba Cloud will authenticate each API request through a signature when each API call is made

The STS service supports the use of both HTTP and HTTPS protocols

Object ACL is an object-level (not bucket level) permission control mechanism. There are currently three levels of access rights: private, public-read, and public-read-write.

"Private" indicates that an object is a private resource, that is, only the owner of the object has read and write permissions on the object, and other users can read but have no permission to modify or delete the object.

If the permissions of an object are not set, the permissions of the object are inherited from the bucket.

You can set the ACL associated with an object by examining the X-OSS-Object-ACL header in the HEAD request, when making the PutObjectACL API call.
