ListObjectVersionsCommand

This operation is not supported for directory buckets.

Returns metadata about all versions of the objects in a bucket. You can also use request parameters as selection criteria to return metadata about a subset of all the object versions.

To use this operation, you must have permission to perform the s3:ListBucketVersions action. Be aware of the name difference.

A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately.

To use this operation, you must have READ access to the bucket.

The following operations are related to ListObjectVersions:

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { S3Client, ListObjectVersionsCommand } from "@aws-sdk/client-s3"; // ES Modules import
// const { S3Client, ListObjectVersionsCommand } = require("@aws-sdk/client-s3"); // CommonJS import
const client = new S3Client(config);

const command = new ListObjectVersionsCommand(input);

ListObjectVersionsCommand Input

See ListObjectVersionsCommandInput for more details

Parameter
Type
Description
Bucket
Required
string | undefined

The bucket name that contains the objects.

Note: To supply the Multi-region Access Point (MRAP) to Bucket, you need to install the "aws-sdk/signature-v4-crt" package to your project dependencies. For more information, please go to https://github.com/aws/aws-sdk-js-v3#known-issues

Delimiter
string | undefined

A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes. These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.

EncodingType
EncodingType | undefined

Encoding type used by Amazon S3 to encode the object keys  in the response. Responses are encoded only in UTF-8. An object key can contain any Unicode character. However, the XML 1.0 parser can't parse certain characters, such as characters with an ASCII value from 0 to 10. For characters that aren't supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response. For more information about characters to avoid in object key names, see Object key naming guidelines .

When using the URL encoding type, non-ASCII characters that are used in an object's key name will be percent-encoded according to UTF-8 code values. For example, the object test_file(3).png will appear as test_file%283%29.png.

ExpectedBucketOwner
string | undefined

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).

KeyMarker
string | undefined

Specifies the key to start with when listing objects in a bucket.

MaxKeys
number | undefined

Sets the maximum number of keys returned in the response. By default, the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more. If additional keys satisfy the search criteria, but were not returned because max-keys was exceeded, the response contains true. To return the additional keys, see key-marker and version-id-marker.

OptionalObjectAttributes
OptionalObjectAttributes[] | undefined

Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.

Prefix
string | undefined

Use this parameter to select only those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using prefix to make groups in the same way that you'd use a folder in a file system.) You can use prefix with delimiter to roll up numerous objects into a single result under CommonPrefixes.

RequestPayer
RequestPayer | undefined

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets  in the Amazon S3 User Guide.

This functionality is not supported for directory buckets.

VersionIdMarker
string | undefined

Specifies the object version you want to start listing from.

ListObjectVersionsCommand Output

Parameter
Type
Description
$metadata
Required
ResponseMetadata
Metadata pertaining to this request.
CommonPrefixes
CommonPrefix[] | undefined

All of the keys rolled up into a common prefix count as a single return when calculating the number of returns.

DeleteMarkers
DeleteMarkerEntry[] | undefined

Container for an object that is a delete marker.

Delimiter
string | undefined

The delimiter grouping the included keys. A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes. These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.

EncodingType
EncodingType | undefined

Encoding type used by Amazon S3 to encode object key names in the XML response.

If you specify the encoding-type request parameter, Amazon S3 includes this element in the response, and returns encoded key name values in the following response elements:

KeyMarker, NextKeyMarker, Prefix, Key, and Delimiter.

IsTruncated
boolean | undefined

A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria. If your results were truncated, you can make a follow-up paginated request by using the NextKeyMarker and NextVersionIdMarker response parameters as a starting place in another request to return the rest of the results.

KeyMarker
string | undefined

Marks the last key returned in a truncated response.

MaxKeys
number | undefined

Specifies the maximum number of objects to return.

Name
string | undefined

The bucket name.

NextKeyMarker
string | undefined

When the number of responses exceeds the value of MaxKeys, NextKeyMarker specifies the first key not returned that satisfies the search criteria. Use this value for the key-marker request parameter in a subsequent request.

NextVersionIdMarker
string | undefined

When the number of responses exceeds the value of MaxKeys, NextVersionIdMarker specifies the first object version not returned that satisfies the search criteria. Use this value for the version-id-marker request parameter in a subsequent request.

Prefix
string | undefined

Selects objects that start with the value supplied by this parameter.

RequestCharged
RequestCharged | undefined

If present, indicates that the requester was successfully charged for the request.

This functionality is not supported for directory buckets.

VersionIdMarker
string | undefined

Marks the last version of the key returned in a truncated response.

Versions
ObjectVersion[] | undefined

Container for version information.
