      API Description

      This API is used to get all objects in a bucket and their historical version information. You can also filter certain objects and their version information by specifying relevant parameters. To call this API, you need to have permission to read the bucket.

      Request

      Sample request

      GET /?versions HTTP/1.1
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
Date: GMT Date
Authorization: Auth String

      Note：

      Authorization: Auth String (see Request Signature for details).

      Request parameters

      Parameter Description Type Required
      prefix Matching prefix for object keys. The response will contain only object keys with the specified prefix. string No
      delimiter A character delimiter used to group object keys. Keys that contain identical paths between the prefix (or, if no prefix is specified, the beginning of the string) and the first delimiter are grouped and defined as a Prefix node under CommonPrefixes. The grouped object keys will no longer appear in the subsequent object list. For specific scenarios and usage, see the samples below. string No
      encoding-type Encoding type of the returned value. Valid value: url, meaning that the returned object keys are URL-encoded (percent-encoded) values. For example, "Tencent Cloud" will be encoded to %E8%85%BE%E8%AE%AF%E4%BA%91. string No
      key-marker Marker for the starting object key. Object version entries after this marker will be returned in UTF-8 lexicographical order. string No
      version-id-marker Marker for the starting version ID. Object version entries after this marker will be returned. If NextVersionIdMarker is empty in the last ListVersionsResult response, leave this parameter empty. string No
      max-keys The maximum number (up to 1,000) of keys returned in a response. Defaults to 1000.
      Note: This parameter limits the maximum number of keys (the sum of CommonPrefixes, Version, and DeleteMarker’) COS can return in each ListVersionsResultresponse. If not all objects are listed in a single response, COS will return theNextKeyMarkerandNextVersionIdMarkernodes, the values of which can be used to specifykey-markerandversion-id-marker`, respectively, so that the remaining versions can be listed in your next request.      		 integer No
