You can set the bucket ACL through the interface provided by the TOS SDK. Permissions can be set through the request header and request body.
Prerequisite
- The account that configures the bucket ACL must be the creator of the bucket or have write access to the bucket ACL.
- Only ACL configuration for the main account ID is supported, and sub-accounts are not supported.
Bucket ACL Description
access rights | describe | enumeration type |
access rights | describe | enumeration type |
READ | Allows authorized parties to list objects in buckets for sharding tasks. | PermissionType*.*PermissionRead |
WRITE | Allows authorized parties to create, overwrite, and delete arbitrary objects in the bucket, initialize sharding tasks, upload sharding, merge sharding, and cancel sharding tasks. | PermissionType.PermissionWrite |
READ_ACP | Allows authorized parties to read the bucket ACL. | PermissionType.PermissionReadAcp |
WRITE_ACP | Allows authorized parties to set ACLs for applicable buckets. | PermissionType.PermissionWriteAcp |
FULL_CONTROL | Allows authorized persons to have READ, WRITE, READ_ACP and WRITE_ACP permissions on the bucket. | PermissionType.PermissionFullControl |
Sample code
Set ACL permissions through request body
warning
Before setting ACL permissions for buckets, you must have tos: PutBucketACLpermissions, or WRITE_ACPbucket ACL permissions. For specific operations, please refer to Overview.
