Overview

This API is used to determine whether an object exists and whether you have permission to access it. You can use this API to get the object metadata if you can access it. To call this API, you need to have permission to read the object, or the object is set to public-read (i.e., everyone can read it).


Authorization Description

In the authorization policy, set action to cos:HeadObject. View all actions.

Versioning

With versioning enabled, you can specify the versionId request parameter to get the metadata of an object of a specified version. If the version ID you specify corresponds to a delete marker, HTTP status code “404 (Not Found)” will be returned. If no version ID is specified, the metadata of the latest version will be returned.

Request

Sample request

HEAD /<ObjectKey> HTTP/1.1
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
Date: GMT Date
Authorization: Auth String
Note:
Host:<BucketName-APPID>.cos.<Region>.myqcloud.com, where <BucketName-APPID> is the 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 parameters
