HeadObjectRequest
import type { HeadObjectRequest } from "https://aws-api.deno.dev/v0.4/services/s3.ts?docs=full";
§Properties
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.
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.
The account ID of the expected bucket owner.
If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden
(access denied).
Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.
Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.
Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.
Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.
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.
Because HeadObject
returns only the metadata for an object, this parameter has no effect.
Specifies the algorithm to use to when encrypting the object (for example, AES256).
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.
