是否可以仅使用授权持有者令牌和存储桶名称将文件上传到google云存储？(php代码)

<?php
require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

function uploadFile($bucketName, $objectName, $filePath)
{
    $storage = new StorageClient([
        'keyFilePath' => '/path/to/service-account-key.json',
        'projectId' => 'your-project-id'
    ]);

    $bucket = $storage->bucket($bucketName);
    $object = $bucket->upload(
        fopen($filePath, 'r'),
        ['name' => $objectName]
    );

    echo 'File uploaded successfully.';
}

$bucketName = 'your-bucket-name';
$objectName = 'path/to/your/file.jpg';
$filePath = '/path/to/your/local/file.jpg';

uploadFile($bucketName, $objectName, $filePath);
?>
