Returns a list of bucket objects.

It does not return object contents; use the get method instead.

Output is paginated; you can get a list of up to 1,000 objects per request. If there are more objects, make multiple consecutive requests.

Note

This method has two versions:

  • listObjectsV2: Current version, which is easier to use.
  • listObjectsV1: Previous version.

The same URL, with different request parameters, is used to call both methods. To call listObjectsV2, use the list-type=2 parameter.

For more information on getting started with the API and the general request format, see How to use the S3 API.

RequestRequest

GET /{bucket}?list-type=2&continuation-token=ContinuationToken&delimiter=Delimiter&encoding-type=EncodingType&max-keys=MaxKeys&prefix=Prefix&start-after=StartAfter HTTP/2

Path parametersPath parameters

Parameter Description
bucket Bucket name.

Request parametersRequest parameters

All parameters listed in the table are optional.

Parameter Description
continuation-token Use this parameter to get the next part of the list if all results do not fit in a single response.
To get the next part of the list, use the NextContinuationToken value from the previous response.
delimiter Delimiter character.

If this parameter is specified, Object Storage interprets the key as the path to the file with folders separated by the delimiter character. In the response, the user will get a list of files and folders in the bucket. Files will be output in the Contents elements, and folders, in the CommonPrefixes elements.

If the request also specifies the prefix parameter, Object Storage will return a list of files and folders in the prefix folder.
encoding-type Encoding of server responses.

Object Storage can encode responses in the format requested by the client.

The possible value is url.
max-keys Maximum number of elements in a response.

By default, Object Storage outputs no more than 1,000 Contents and CommonPrefixes elements. Use this parameter if you need fewer than 1,000 elements in a single response.

If the selection criteria are met by more keys than can fit into the output, the response will contain <IsTruncated>true</IsTruncated>.

To get all the output elements if their number exceeds max-keys, run multiple requests to Object Storage with the continuation-token parameter, where the continuation-token of each request is equal to the value of the NextContinuationToken element in the previous response.
prefix String to start the key from.

Object Storage selects only those keys which start with prefix.

You can use this parameter together with delimiter. In this case, the output logic is determined by the delimiter parameter.
start-after Key to start the listing from.
