s3_list_object_versions: Returns metadata about all versions of the objects in a bucket

Description

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.

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.

This action is not supported by Amazon S3 on Outposts.

Usage

s3_list_object_versions(Bucket, Delimiter, EncodingType, KeyMarker,
  MaxKeys, Prefix, VersionIdMarker, ExpectedBucketOwner)

Value

A list with the following syntax:

list(
  IsTruncated = TRUE|FALSE,
  KeyMarker = "string",
  VersionIdMarker = "string",
  NextKeyMarker = "string",
  NextVersionIdMarker = "string",
  Versions = list(
    list(
      ETag = "string",
      Size = 123,
      StorageClass = "STANDARD",
      Key = "string",
      VersionId = "string",
      IsLatest = TRUE|FALSE,
      LastModified = as.POSIXct(
        "2015-01-01"
      ),
      Owner = list(
        DisplayName = "string",
        ID = "string"
      )
    )
  ),
  DeleteMarkers = list(
    list(
      Owner = list(
        DisplayName = "string",
        ID = "string"
      ),
      Key = "string",
      VersionId = "string",
      IsLatest = TRUE|FALSE,
      LastModified = as.POSIXct(
        "2015-01-01"
      )
    )
  ),
  Name = "string",
  Prefix = "string",
  Delimiter = "string",
  MaxKeys = 123,
  CommonPrefixes = list(
    list(
      Prefix = "string"
    )
  ),
  EncodingType = "url"
)

Arguments

Bucket

[required] The bucket name that contains the objects.

Delimiter

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

KeyMarker

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

MaxKeys

Sets the maximum number of keys returned in the response. By default the API 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 <isTruncated>true</isTruncated>. To return the additional keys, see key-marker and version-id-marker.

Prefix

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 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.

VersionIdMarker

Specifies the object version you want to start listing from.

ExpectedBucketOwner

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.

Request syntax

svc$list_object_versions(
  Bucket = "string",
  Delimiter = "string",
  EncodingType = "url",
  KeyMarker = "string",
  MaxKeys = 123,
  Prefix = "string",
  VersionIdMarker = "string",
  ExpectedBucketOwner = "string"
)

Examples

if (FALSE) {
# The following example return versions of an object with specific key
# name prefix. The request limits the number of items returned to two. If
# there are are more than two object version, S3 returns NextToken in the
# response. You can specify this token value in your next request to fetch
# next set of object versions.
svc$list_object_versions(
  Bucket = "examplebucket",
  Prefix = "HappyFace.jpg"
)
