Requester Pays

Scenarios

The requester-pays configuration allows the requester to pay for data transfer and API calls associated with accessing the requested OBS resources, while the bucket owner only pays for data storage. If your bucket is the source for large-scale data sharing, you can enable requester-pays for the bucket, so that the requester pays for data access in the bucket. Otherwise, you, the bucket owner, will pay for all costs associated with the bucket.

Limitations and Constraints

• Only buckets of version 3.0 support the requester-pays function.
• A requester-pays bucket does not allow access by anonymous users.
• The x-obs-request-payer: requester header must be included in the request accessing a requester-pays bucket, indicating that the requester agrees to pay for the request and associated data transfer. Without this header, the identity authentication fails, and error 403 (Forbidden) is returned. The response returned by the server includes the x-obs-request-charged: requester header, indicating the requester is billed for this request.

  Sample request for downloading an object by a requester

  1 2 3 4 5

  GET /ObjectName HTTP/1.1 Host: bucketname.obs.region.example.com Date: date Authorization: authorization x-obs-request-payer: requester

  Sample response

  1 2 3 4 5 6 7

  HTTP/1.1 status_code x-obs-request-charged: requester Content-Type: type Date: date Content-Length: length <Object Content>

• If the bucket owner or an IAM user under the same account as the bucket owner accesses a requester-pays bucket, the x-obs-request-payer: requester header is not required. In such case, no matter whether this header is included in the request, the response does not include the header.
