Retrieves objects from Amazon S3. To use GET
, you must have READ
access to the object. If you grant READ
access to the anonymous user,
you can return the object without using an authorization header.
An Amazon S3 bucket has no directory hierarchy such as you would find in
a typical computer file system. You can, however, create a logical
hierarchy by using object key names that imply a folder structure. For
example, instead of naming an object sample.jpg
, you can name it
photos/2006/February/sample.jpg
.
To get an object from such a logical hierarchy, specify the full key
name for the object in the GET
operation. For a virtual hosted-style
request example, if you have the object
photos/2006/February/sample.jpg
, specify the resource as
/photos/2006/February/sample.jpg
. For a path-style request
example, if you have the object photos/2006/February/sample.jpg
in
the bucket named examplebucket
, specify the resource as
/examplebucket/photos/2006/February/sample.jpg
. For more
information about request types, see
HTTP Host Header Bucket Specification.
For more information about returning the ACL of an object, see GetObjectAcl.
If the object you are retrieving is stored in the S3 Glacier or S3
Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or
S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the
object you must first restore a copy using
RestoreObject.
Otherwise, this action returns an InvalidObjectStateError
error. For
information about restoring archived objects, see
Restoring Archived Objects.
Encryption request headers, like x-amz-server-side-encryption
, should
not be sent for GET requests if your object uses server-side encryption
with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed
encryption keys (SSE-S3). If your object does use these types of keys,
you’ll get an HTTP 400 BadRequest error.
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 GET the object, you must use the following headers:
- 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).
Assuming you have the relevant permission to read object tags, the
response also returns the x-amz-tagging-count
header that provides the
count of number of tags associated with the object. You can use
GetObjectTagging
to retrieve the tag set associated with an object.
Permissions
You need the relevant read object (or version) permission for this
operation. For more information, see
Specifying Permissions in a Policy.
If the object you request does not exist, the error 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 will return an HTTP status code 404 ("no such key") error. - If you don’t have the
s3:ListBucket
permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning
By default, the GET action returns the current version of an object. To
return a different version, use the versionId
subresource.
- If you supply a
versionId
, you need thes3:GetObjectVersion
permission to access a specific version of an object. If you request a specific version, you do not need to have thes3:GetObject
permission. - 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.
For more information about versioning, see PutBucketVersioning.
Overriding Response Header Values
There are times when you want to override certain response header values
in a GET response. For example, you might override the
Content-Disposition
response header value in your GET request.
You can override values for a set of response headers using the
following query parameters. These response header values are sent only
on a successful request, that is, when status code 200 OK is returned.
The set of headers you can override using these parameters is a subset
of the headers that Amazon S3 accepts when you create an object. The
response headers that you can override for the GET response are
Content-Type
, Content-Language
, Expires
, Cache-Control
,
Content-Disposition
, and Content-Encoding
. To override these header
values in the GET response, you use the following request parameters.
You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.
response-content-type
response-content-language
response-expires
response-cache-control
response-content-disposition
response-content-encoding
Additional Considerations about Request Headers
If both of the If-Match
and If-Unmodified-Since
headers are present
in the request as follows: If-Match
condition evaluates to true
,
and; If-Unmodified-Since
condition evaluates to false
; then, S3
returns 200 OK and the data requested.
If both of the If-None-Match
and If-Modified-Since
headers are
present in the request as follows: If-None-Match
condition evaluates
to false
, and; If-Modified-Since
condition evaluates to true
;
then, S3 returns 304 Not Modified response code.
For more information about conditional requests, see RFC 7232.

The base64-encoded, 256-bit SHA-256 digest of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
getObjectResponse_contentDisposition :: Lens' GetObjectResponse (Maybe Text) Source #
Specifies presentational information for the object.
getObjectResponse_contentEncoding :: Lens' GetObjectResponse (Maybe Text) Source #
Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.
getObjectResponse_contentLanguage :: Lens' GetObjectResponse (Maybe Text) Source #
The language the content is in.
getObjectResponse_contentLength :: Lens' GetObjectResponse (Maybe Integer) Source #
Size of the body in bytes.
getObjectResponse_contentRange :: Lens' GetObjectResponse (Maybe Text) Source #
The portion of the object returned in the response.
getObjectResponse_contentType :: Lens' GetObjectResponse (Maybe Text) Source #
A standard MIME type describing the format of the object data.
getObjectResponse_deleteMarker :: Lens' GetObjectResponse (Maybe Bool) Source #
Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.
getObjectResponse_eTag :: Lens' GetObjectResponse (Maybe ETag) Source #
An entity tag (ETag) is an opaque identifier assigned by a web server to a specific version of a resource found at a URL.
getObjectResponse_expiration :: Lens' GetObjectResponse (Maybe Text) Source #
If the object expiration is configured (see PUT Bucket lifecycle), the
response includes this header. It includes the expiry-date
and
rule-id
key-value pairs providing object expiration information. The
value of the rule-id
is URL-encoded.
getObjectResponse_expires :: Lens' GetObjectResponse (Maybe UTCTime) Source #
The date and time at which the object is no longer cacheable.
getObjectResponse_lastModified :: Lens' GetObjectResponse (Maybe UTCTime) Source #
Creation date of the object.
getObjectResponse_metadata :: Lens' GetObjectResponse (HashMap Text Text) Source #
A map of metadata to store with the object in S3.
getObjectResponse_missingMeta :: Lens' GetObjectResponse (Maybe Int) Source #
This is set to the number of metadata entries not returned in
x-amz-meta
headers. This can happen if you create metadata using an
API like SOAP that supports more flexible metadata than the REST API.
For example, using SOAP, you can create metadata whose values are not
legal HTTP headers.
getObjectResponse_objectLockLegalHoldStatus :: Lens' GetObjectResponse (Maybe ObjectLockLegalHoldStatus) Source #
Indicates whether this object has an active legal hold. This field is only returned if you have permission to view an object's legal hold status.
getObjectResponse_objectLockMode :: Lens' GetObjectResponse (Maybe ObjectLockMode) Source #
The Object Lock mode currently in place for this object.
getObjectResponse_objectLockRetainUntilDate :: Lens' GetObjectResponse (Maybe UTCTime) Source #
The date and time when this object's Object Lock will expire.
getObjectResponse_partsCount :: Lens' GetObjectResponse (Maybe Int) Source #
The count of parts this object has. This value is only returned if you
specify partNumber
in your request and the object was uploaded as a
multipart upload.
getObjectResponse_replicationStatus :: Lens' GetObjectResponse (Maybe ReplicationStatus) Source #
Amazon S3 can return this if your request involves a bucket that is either a source or destination in a replication rule.
getObjectResponse_requestCharged :: Lens' GetObjectResponse (Maybe RequestCharged) Source #
Undocumented member.
getObjectResponse_restore :: Lens' GetObjectResponse (Maybe Text) Source #
Provides information about object restoration action and expiration time of the restored object copy.
getObjectResponse_sSECustomerAlgorithm :: Lens' GetObjectResponse (Maybe Text) Source #
If server-side encryption with a customer-provided encryption key was requested, the response will include this header confirming the encryption algorithm used.
getObjectResponse_sSECustomerKeyMD5 :: Lens' GetObjectResponse (Maybe Text) Source #
If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide round-trip message integrity verification of the customer-provided encryption key.
getObjectResponse_sSEKMSKeyId :: Lens' GetObjectResponse (Maybe Text) Source #
If present, specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetric customer managed key that was used for the object.
getObjectResponse_serverSideEncryption :: Lens' GetObjectResponse (Maybe ServerSideEncryption) Source #
The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).
getObjectResponse_storageClass :: Lens' GetObjectResponse (Maybe StorageClass) Source #
Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.
getObjectResponse_tagCount :: Lens' GetObjectResponse (Maybe Int) Source #
The number of tags, if any, on the object.
getObjectResponse_versionId :: Lens' GetObjectResponse (Maybe ObjectVersionId) Source #
Version of the object.
getObjectResponse_websiteRedirectLocation :: Lens' GetObjectResponse (Maybe Text) Source #
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.
getObjectResponse_httpStatus :: Lens' GetObjectResponse Int Source #
