Checking object integrity of multipart upload - Missing GetObjectAttributes in Aws::S3::Model Namespace

[WolfgangVogl]

Currently I'm checking possible ways of checking/ensuring object integrity.
As of this Post https://aws.amazon.com/de/blogs/aws/new-additional-checksum-algorithms-for-amazon-s3/ I thought I can check the result/checksum of a MultipartUpload by using GetObjectAttributes.

But I can't find it in the Aws::S3::Model Namespace - I could find a similar call in Aws::CloudDirectory::Model but I'm not sure that this is the right one and if it is - why isn't it in the S3 Namespace? It seems I couldn't use my S3Client Instance to send the request...

Just for completeness, here's what I want to accomplish:

• Start a multipart upload within my code
• Generating n presigned URLs (part 1 to n) for the multipart uploads for another client
• After the client finished the uploading it sends the eTags and the expected checksum of the whole file to my code
• I finish the multipart upload (CompleteMultipartUpload) using the given eTags and I want to ensure the file is consistent.
  -> In the response of the CompleteMultipartUpload the checksum headers are not set... do i miss something to set?
