  'domain' =&gt; 'https://images.your_domain.com'

$auth = new Auth($cfg['access'], $cfg['secret']);
// 创建一个过期时间为1小时的临时上传令牌
$token = $auth-&gt;uploadToken($cfg['bucket'], null, 3600);

$filePath = "./illustration.png";

$uploadMgr = new UploadManager();
list($ret, $err) = $uploadMgr-&gt;putFile($token, null, $filePath);
