Obtaining Bucket Versioning Status
Functions
This API is used to obtain the versioning status of a bucket. If versioning is not configured for the bucket, no versioning status of the bucket will be returned. For more information about versioning, see Versioning.
Authorization Information
To call this API, you must be the bucket owner or have the permission to obtain the versioning status 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:GetBucketVersioning permission. For details, see Creating a Custom IAM Policy.
- If you use bucket policies for authorization, you need to grant the obs:bucket:GetBucketVersioning permission. For details, see Creating a Custom Bucket Policy.

Using SDKs to Call APIs
You are advised to use OBS SDKs to call APIs. SDKs encapsulate APIs to simplify development. You can call SDK API functions to access OBS without manually calculating signatures.
