Yandex Object Storage

listObjects method

Returns a list of bucket objects.

Pagination is used for output. You can get a list of up to 1000 objects per request. If there are more objects, make several consecutive requests.

Request

GET /{bucket} HTTP/1.1

Path parameters

Parameter Description
bucket Bucket name.

Query parameters

All the parameters listed in the table are optional.

Parameter Description
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 response to the request, the user gets a list of files and folders in the bucket. Files are output in the Contents elements, and folders in the CommonPrefixes elements.

If the request also specifies the prefix parameter, Object Storage returns a list of files and folders in the prefix folder.
marker Key to start the output from.

In the resulting output, Object Storage leaves the keys starting from the one following the marker.
max-keys Maximum number of elements in a response.

By default, Object Storage returns a maximum of 1000 Contents and CommonPrefixes elements. This parameter should be used if you need to get less than 1000 elements in a single response.

If the number of keys meeting the selection criteria is greater than the number that could fit in the output, the response contains <IsTruncated>true</IsTruncated>.

To get all output elements if their number exceeds the max-keys value, make several consecutive requests to Object Storage with the marker parameter, where, for each request, the marker is equal to the value of the MaxKeys element from the previous response.
prefix String to start the key from.

Object Storage selects only those keys that start with prefix.

Can be used simultaneously with the delimiter parameter. In this case, the output logic is the same as that specified in the delimiter parameter description.
