Overview

This document provides sample code for quickly checking whether an object exists in a bucket.
The sample code actually calls the HEAD Object COS API and is a simplified version of the API.
In addition to checking whether an object exists, HeadObject returns object metadata. To view the SDK API that contains the full functionality of HeadObject, see Querying Object Metadata.

$secretKey = "SECRETKEY"; //Replace it with the actual `SecretKey`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
$region = "ap-beijing"; //Replace it with the actual `region`, which can be viewed in the console at https://console.tencentcloud.com/cos5/bucket
$cosClient = new Qcloud\\Cos\\Client(
    array(
        'region' => $region,
        'schema' => 'https', // Protocol header, which is http by default
        'credentials'=> array(

            'secretKey' => $secretKey)));
try {
    $result = $cosClient->doesObjectExist(
        'examplebucket-125000000', // Bucket name in the format of `BucketName-APPID`, which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
        'exampleobject' // Object name
    );
    // Request succeeded
