The name of the bucket containing the object.
#checksum_mode ⇒ String
To retrieve the checksum, this parameter must be enabled.
#expected_bucket_owner ⇒ String
The account ID of the expected bucket owner.
#if_match ⇒ String
Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.
#if_modified_since ⇒ Time
Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.
#if_none_match ⇒ String
Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.
#if_unmodified_since ⇒ Time
Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.
#key ⇒ String
The object key.
#part_number ⇒ Integer

Instance Attribute Details

#bucket ⇒ `String`

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 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 in the Amazon S3 User Guide.

Returns:

#checksum_mode ⇒ `String`

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.

end

#sse_customer_key ⇒ `String`

Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key.
