阿里云OSS文件同步到本地服务器，并生成防盗链地址：
```php
require_once dirname(dirname(dirname(__FILE__))) . '/vendor/aliyun/oss/OssClient.php';
$accessKeyId = "这个不用说了吧";
$accessKeySecret = "这个不用说了吧";
$endpoint = "http://oss-cn-桶的地区.aliyuncs.com";
$bucket= "桶的名称";

foreach ($list as $k=>$v) {
	$object = $v['mp3'];
	$name = 'data/order_sound/'.$v['mp3'];
	$localfile = ROOT_PATH.$name;
	$options = array(
		OssClient::OSS_FILE_DOWNLOAD => $localfile,
		OssClient::OSS_HEADERS => array(
			'Content-Disposition' => 'attachment'
		)
	);
	try{
		$ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
		$ossClient->getObject($bucket, $object, $options);
		$time = time();
		// 生成防盗链地址，直接扔到前端mp3的src里
		$list[$k]['mp3_url'] = 'mp3.php?time='.$time.'&sign='.md5(sha1($time.$name)).'&mp3='.$name;
	} catch(OssException $e) {
		// 同步失败会抛出错误的
		printf(__FUNCTION__ . ": FAILED\n");
		printf($e->getMessage() . "\n");
		return;
	}
}
```

防盗链`mp3.php`的代码，用于输出音频文件内容：
```php
$time = $param['time'];
$mp3 = $param['mp3'];
$sign = $param['sign'];

if (($time+600) <= time()) {
	exit;
}

if (md5(sha1($time.$mp3)) != $sign) {
	exit;
}

$filePath = ROOT_PATH.$mp3;

if (!file_exists($filePath)) {
	exit;
}

set_time_limit(0);
header("Content-type: audio/mpeg");
header("Age:0");

$fileSize = filesize($filePath);
$begin = 0;
$end = $fileSize - 1;

header("Content-Length: " . ($end - $begin + 1));
header("Content-Range: bytes " . $begin . "-" . $end . "/" . $fileSize);
header("Vary:Accept-Encoding");
header("Cache-Control:max-age=315360000");
$fobj = fopen($filePath, 'rb');
// 如果没有权限打开这个文件，而下面的while就会走进死循环，这里要注意下
if ($fobj === false) {
	exit;
}
ob_clean();
flush();
fseek($fobj, $begin);
//设置分流
$buffer = 1024 * 10;
//来个文件字节计数器
$count = 0;
while(!feof($fobj)){
	$p = min($buffer,$end - $begin + 1);
	$begin += $p;
	$data = fread($fobj,$buffer);
	echo $data;    //传数据给浏览器端
}
fclose($fobj);
exit;
```
