Instance Attribute Details

#bucketString

The name of the bucket containing the object.

When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see

Using access points][1

in the *Amazon S3 User Guide*.

When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form ` AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com`. When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see

Using Amazon S3 on Outposts][2

in the *Amazon S3 User Guide*.

#checksum_modeString

To retrieve the checksum, this parameter must be enabled.

In addition, if you enable `ChecksumMode` and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the `kms:Decrypt` action for the request to succeed.
