Overview

This API is equivalent to the List Objects API and can be used to list some or all objects in a bucket. To call this API, you need to have permission to read the bucket.
Note:
If you upload an object to the bucket and call the GET Bucket API immediately, due to the eventual consistency characteristic of this API, the response may not include the newly uploaded object.


Requests

Request example

GET / HTTP/1.1
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
Date: GMT Date
Authorization: Auth String
Note:
In Host: <BucketName-APPID>.cos.<Region>.myqcloud.com, <BucketName-APPID> is the bucket name followed by the APPID, such as examplebucket-1250000000 (see Bucket Overview > Basic Information and Bucket Overview > Bucket Naming Conventions), and <Region> is a COS region (see Regions and Access Endpoints).
Authorization: Auth String (See Request Signature for details.)

Request fields

Field
Description
Type
Required
prefix
Key prefix to query objects by
String
No
delimiter
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
marker
Marker for the starting object key. Object key entries will be returned in UTF-8 lexicographical order, starting from the first object key after the marker.
string
No
max-keys
The maximum number (up to 1,000) of keys returned in the response. Defaults to 1000.
Note: This parameter limits the maximum number of keys (the sum of CommonPrefixes and Contents) COS can return in each List Objects response. If not all objects are listed in a single response, COS will return the NextMarker node, the value of which can be used to specify marker so that the remaining objects can be listed in your next request.
integer
No

string
EncodingType
ListBucketResult
Encoding type, which corresponds to the encoding-type parameter in the request. This node will be returned only when the encoding-type parameter is specified in the request.
string
Prefix
ListBucketResult
Matching prefix to filter object keys. This node corresponds to the Prefix parameter in the request.
