Struct aws_sdk_s3::operation::head_object::builders::HeadObjectFluentBuilder
source · pub struct HeadObjectFluentBuilder { /* private fields */ }
Expand description
Fluent builder constructing a request to HeadObject
.
The HEAD
operation retrieves metadata from an object without returning the object itself. This operation is useful if you're interested only in an object's metadata.
A HEAD
request has the same options as a GET
operation on an object. The response is identical to the GET
response except that there is no response body. Because of this, if the HEAD
request generates an error, it returns a generic code, such as 400 Bad Request
, 403 Forbidden
, 404 Not Found
, 405 Method Not Allowed
, 412 Precondition Failed
, or 304 Not Modified
. It's not possible to retrieve the exact exception of these error codes.
Request headers are limited to 8 KB in size. For more information, see Common Request Headers.
Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name
. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.
- Permissions
-
-
General purpose bucket permissions - To use
HEAD
, you must have thes3:GetObject
permission. You need the relevant read object (or version) permission for this operation. For more information, see Actions, resources, and condition keys for Amazon S3 in the Amazon S3 User Guide.If the object you request doesn't exist, the error that Amazon S3 returns depends on whether you also have the
s3:ListBucket
permission.-
If you have the
s3:ListBucket
permission on the bucket, Amazon S3 returns an HTTP status code404 Not Found
error. -
If you don’t have the
s3:ListBucket
permission, Amazon S3 returns an HTTP status code403 Forbidden
error.
-
-
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the
CreateSession
API operation for session-based authorization. Specifically, you grant thes3express:CreateSession
permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make theCreateSession
API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make anotherCreateSession
API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, seeCreateSession
.
-
- Encryption
-
Encryption request headers, like
x-amz-server-side-encryption
, should not be sent forHEAD
requests if your object uses server-side encryption with Key Management Service (KMS) keys (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or server-side encryption with Amazon S3 managed encryption keys (SSE-S3). Thex-amz-server-side-encryption
header is used when youPUT
an object to S3 and want to specify the encryption method. If you include this header in aHEAD
request for an object that uses these types of keys, you’ll get an HTTP400 Bad Request
error. It's because the encryption method can't be changed when you retrieve the object.If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers to provide the encryption key for the server to be able to retrieve the object's metadata. The headers are:
-
x-amz-server-side-encryption-customer-algorithm
-
x-amz-server-side-encryption-customer-key
-
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.
Directory bucket permissions - For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (
AES256
) is supported. -
- Versioning
-
-
If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes
x-amz-delete-marker: true
in the response. -
If the specified version is a delete marker, the response returns a
405 Method Not Allowed
error and theLast-Modified: timestamp
response header.
-
Directory buckets - Delete marker is not supported by directory buckets.
-
Directory buckets - 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 specifynull
to theversionId
query parameter in the request.
-
- HTTP Host header syntax
-
Directory buckets - The HTTP Host header syntax is
Bucket_name.s3express-az_id.region.amazonaws.com
.

Implementations§
source§impl HeadObjectFluentBuilder
impl HeadObjectFluentBuilder
sourcepub fn as_input(&self) -> &HeadObjectInputBuilder
pub fn as_input(&self) -> &HeadObjectInputBuilder
Access the HeadObject as a reference.
sourcepub async fn send(
self,
) -> Result<HeadObjectOutput, SdkError<HeadObjectError, HttpResponse>>
pub async fn send( self, ) -> Result<HeadObjectOutput, SdkError<HeadObjectError, HttpResponse>>
Sends the request and returns the response.
If an error occurs, an SdkError
will be returned with additional details that
can be matched against.
By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.
sourcepub fn customize(
self,
) -> CustomizableOperation<HeadObjectOutput, HeadObjectError, Self>
pub fn customize( self, ) -> CustomizableOperation<HeadObjectOutput, HeadObjectError, Self>
Consumes this builder, creating a customizable operation that can be modified before being sent.
sourcepub async fn presigned(
self,
presigning_config: PresigningConfig,
) -> Result<PresignedRequest, SdkError<HeadObjectError, HttpResponse>>
pub async fn presigned( self, presigning_config: PresigningConfig, ) -> Result<PresignedRequest, SdkError<HeadObjectError, HttpResponse>>
Creates a presigned request for this operation.
The presigning_config
provides additional presigning-specific config values, such as the
amount of time the request should be valid for after creation.
Presigned requests can be given to other users or applications to access a resource or perform an operation without having access to the AWS security credentials.
Important: If you’re using credentials that can expire, such as those from STS AssumeRole or SSO, then the presigned request can only be valid for as long as the credentials used to create it are.
