If you have any questions during development, post them on the Issues page of GitHub.
Restrictions
- To obtain the logging configuration of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketLogging in IAM or GetBucketLogging in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.

PERMISSION_READ |
READ |
Read permission. A grantee with this permission for a bucket can obtain the list of objects, multipart uploads, bucket metadata, and object versions in the bucket. A grantee with this permission for an object can obtain the object content and metadata. |
PERMISSION_WRITE |
WRITE |
Write permission. A grantee with this permission for a bucket can upload, overwrite, and delete any object or part in the bucket. This permission is not available for objects. |
PERMISSION_READ_ACP |
READ_ACP |
Permission to read an ACL. A grantee with this permission can obtain the ACL of a bucket or object. A bucket or object owner has this permission for their bucket or object by default. |
PERMISSION_WRITE_ACP |
WRITE_ACP |
Permission to modify an ACL. A grantee with this permission can update the ACL of a bucket or object. A bucket or object owner has this permission for their bucket or object by default. This permission allows the grantee to change the access control policies, meaning the grantee has full control over a bucket or object. |
PERMISSION_FULL_CONTROL |
FULL_CONTROL |
Full control access, including read and write permissions for a bucket and its ACL, or for an object and its ACL. A grantee with this permission for a bucket has READ, WRITE, READ_ACP, and WRITE_ACP permissions for the bucket. A grantee with this permission for an object has READ, WRITE, READ_ACP, and WRITE_ACP permissions for the object. |
