NAME
Paws::S3::HeadObject - Arguments for method HeadObject on Paws::S3
DESCRIPTION
This class represents the parameters used for calling the method HeadObject on the Amazon Simple Storage Service service. Use the attributes of this class as arguments to method HeadObject.
You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to HeadObject.
SYNOPSIS
my $s3 = Paws->service('S3');
# To retrieve metadata of an object without returning the object itself
# The following example retrieves an object metadata.
my $HeadObjectOutput = $s3->HeadObject(
'Bucket' => 'examplebucket',
'Key' => 'HappyFace.jpg'
);
# Results:
my $AcceptRanges = $HeadObjectOutput->AcceptRanges;
my $ContentLength = $HeadObjectOutput->ContentLength;
my $ContentType = $HeadObjectOutput->ContentType;
my $ETag = $HeadObjectOutput->ETag;
my $LastModified = $HeadObjectOutput->LastModified;
my $Metadata = $HeadObjectOutput->Metadata;
my $VersionId = $HeadObjectOutput->VersionId;
# Returns a L<Paws::S3::HeadObjectOutput> object.Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/s3/HeadObject
ATTRIBUTES
REQUIRED Bucket => Str
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 AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points (https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-access-points.html) 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 AWS 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 (https://docs.aws.amazon.com/AmazonS3/latest/userguide/S3onOutposts.html) in the Amazon S3 User Guide.
ExpectedBucketOwner => Str
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.
IfMatch => Str
Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed).
IfModifiedSince => Str
Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).
IfNoneMatch => Str
Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).
IfUnmodifiedSince => Str
Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).
REQUIRED Key => Str
The object key.
PartNumber => Int
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.
Range => Str
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 (http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35).
Amazon S3 doesn't support retrieving multiple ranges of data per GET request.
RequestPayer => Str
Valid values are: "requester"
SSECustomerAlgorithm => Str
Specifies the algorithm to use to when encrypting the object (for example, AES256).
SSECustomerKey => Str
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.
SSECustomerKeyMD5 => Str
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.
VersionId => Str
VersionId used to reference a specific version of the object.
