Overview

This API is used to create a bucket under a specified account. A signature needs to be carried in Authorization and anonymous calls are not supported. By default, the bucket creator is the bucket owner.
Note:
If no access permission is specified for a bucket when it is created, private (private read/write) will be used by default.
To create an MAZ bucket, you should indicate the bucket configuration through the request body; otherwise, you don't need to pass in the request body.
