在PHP语言中计算谷歌云存储对象的md5Hash或crc32

// 安装并引入谷歌云存储的官方库
require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

// 设置谷歌云存储的项目ID和密钥路径
$projectId = 'your_project_id';
$keyFilePath = '/path/to/your/service-account-key.json';

// 创建谷歌云存储客户端
$storage = new StorageClient([
    'projectId' => $projectId,
    'keyFilePath' => $keyFilePath
]);

// 指定要计算MD5Hash的谷歌云存储对象的存储桶名称和对象名称
$bucketName = 'your_bucket_name';
$objectName = 'your_object_name';

// 获取对象的MD5Hash
$bucket = $storage->bucket($bucketName);
$object = $bucket->object($objectName);
$md5Hash = $object->info()['md5Hash'];

echo "MD5Hash: " . $md5Hash;
