s3_get_object_attributes: Retrieves all the metadata from an object without returning the object itself

Description

Retrieves all the metadata from an object without returning the object itself. This operation is useful if you're interested only in an object's metadata.

See https://www.paws-r-sdk.com/docs/s3_get_object_attributes/ for full documentation.

Usage

s3_get_object_attributes(
  Bucket,
  Key,
  VersionId = NULL,
  MaxParts = NULL,
  PartNumberMarker = NULL,
  SSECustomerAlgorithm = NULL,
  SSECustomerKey = NULL,
  SSECustomerKeyMD5 = NULL,
  RequestPayer = NULL,
  ExpectedBucketOwner = NULL,
  ObjectAttributes
)

Arguments

Bucket

[required] The name of the bucket that contains the object.

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, 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.

Access points and Object Lambda access points are not supported by directory buckets.

S3 on Outposts - When you use 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 you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

Key

[required] The object key.

VersionId

The version ID used to reference a specific version of the object.

S3 Versioning isn't enabled and supported for directory buckets. For this API operation, only the null value of the version ID is supported by directory buckets. You can only specify null to the versionId query parameter in the request.

MaxParts

Sets the maximum number of parts to return.

PartNumberMarker

Specifies the part after which listing should begin. Only parts with higher part numbers will be listed.

SSECustomerAlgorithm

Specifies the algorithm to use when encrypting the object (for example, AES256).

This functionality is not supported for directory buckets.

SSECustomerKey

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.

This functionality is not supported for directory buckets.

SSECustomerKeyMD5

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.

This functionality is not supported for directory buckets.

RequestPayer

ExpectedBucketOwner

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

ObjectAttributes

[required] Specifies the fields at the root level that you want returned in the response. Fields that you do not specify are not returned.
