Obtaining Bucket ACL Information

Functions

This operation returns the ACL information of a bucket. To obtain the ACL of a bucket, you need to have the READ_ACP or FULL_CONTROL permission for the bucket.

Authorization Information

To call this API, you must be the bucket owner or have the permission to obtain the ACL information of a bucket. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.

  • If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
    • If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you need to grant the obs:bucket:GetBucketAcl permission. For details, see Creating a Custom IAM Policy.
    • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you need to grant the obs:bucket:getBucketAcl permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.
