PHP上传视频转码如何取到 hash FpjkD7IOJe2vgI6sRMi-0erHYLaz key FpjkD7IOJe2vgI6sRMi-0erHYLaz persistentId 551903297823de4068cc6910 这些数据？

$putPolicy = new Qiniu_RS_PutPolicy($bucket);

$putPolicy->Scope               = "{$bucket}";
$putPolicy->Expires             = time() + (24 * 60 * 60);//24小时

$sFileName   = Qiniu_Encode("qiniu:{$newFileName}.mp4");//domain: 


$putPolicy->PersistentOps       = "avthumb/mp4/r/24/vcodec/libx264/acodec/libfaac|saveas/{$sFileName}";
$putPolicy->PersistentNotifyUrl = 'http://t.refineit.cn:88/qiniu2/p_notify_url.php';
$upToken = $putPolicy->Token(null);
