Obtaining Bucket Tags (SDK for Python)
Function
If you add tags to a bucket, SDRs generated for the requests sent to this bucket will include these tags, so you can use the tags to classify SDRs for detailed cost analysis. For example, if you have an application that uploads its running data to a bucket, you can tag the bucket with the application name. In this manner, the costs on the application can be analyzed using tags in SDRs.
This API returns the tags of a bucket.
Restrictions
- To obtain the bucket tags, you must be the bucket owner or have the required permission (obs:bucket:GetBucketTagging in IAM or GetBucketTagging 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.
