data as a hash: { bucket: "BucketName", # required if_match: "IfMatch", if_modified_since: Time.now, if_none_match: "IfNoneMatch", if_unmodified_since: Time.now, key: "ObjectKey", # required range: "Range", version_id: "ObjectVersionId", sse_customer_algorithm: "SSECustomerAlgorithm", sse_customer_key: "SSECustomerKey", sse_customer_key_md5: "SSECustomerKeyMD5", request_payer: "requester", # accepts requester part_number: 1, expected_bucket_owner: "AccountId", }
@!attribute [rw] bucket
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 using 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 S3 on Outposts][2] in the *Amazon S3 User Guide*.

@!attribute [rw] if_match
Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed). @return [String]
@!attribute [rw] if_modified_since
Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified). @return [Time]
@!attribute [rw] if_none_match
Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified). @return [String]
@!attribute [rw] if_unmodified_since
Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed). @return [Time]
@!attribute [rw] key
The object key. @return [String]
@!attribute [rw] range
Downloads the specified range bytes of an object. For more information about the HTTP Range header, see [http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35][1]. <note markdown="1"> Amazon S3 doesn't support retrieving multiple ranges of data per `GET` request. </note> [1]: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35 @return [String]
@!attribute [rw] version_id
VersionId used to reference a specific version of the object. @return [String]
@!attribute [rw] sse_customer_algorithm
Specifies the algorithm to use to when encrypting the object (for example, AES256). @return [String]
@!attribute [rw] sse_customer_key
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. The key must be appropriate for use with the algorithm specified in the `x-amz-server-side-encryption-customer-algorithm` header. @return [String]
@!attribute [rw] sse_customer_key_md5
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error. @return [String]
@!attribute [rw] request_payer
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from requester pays buckets, see [Downloading Objects in Requestor Pays Buckets][1] in the *Amazon S3 User Guide*. [1]: https://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html @return [String]
@!attribute [rw] part_number
Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object. @return [Integer]
@!attribute [rw] expected_bucket_owner
The account ID of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP `403 (Access Denied)` error. @return [String]
