#教程# 阿里云国际 – 流量包脚本监控 超流量自动关机

很多同学在使用#阿里云##国际#的时候被无聊的人#刷流量#，导致很快#流量包#被用完，这里给出个 PHP 的#监控#，用定时 cron 实现超流量就自动关机。

把下面的文件保存为 datamonitoring.php

{
$canonicalizedQueryString .= ‘&’ . percentEncode($key)
. ‘=’ . percentEncode($value);
}
// 生成用于计算签名的字符串 stringToSign
$stringToSign = ‘GET&%2F&’ . percentencode(substr($canonicalizedQueryString, 1));
// 计算签名，注意 accessKeySecret 后面要加上字符’&’
$signature = base64_encode(hash_hmac(‘sha1’, $stringToSign, $accessKeySecret . ‘&’, true));
return $signature;
}
function get_action($data,$Version,$host){
date_default_timezone_set(“GMT”);
$dateTimeFormat = ‘Y-m-d\TH:i:s\Z’;
global $AccessKey_ID;
global $Access_Key_Secret;

自行更改 用户 AccessKey 地区 机器 ID
如果只有 1 台 ecs 且是新加坡的 只需修改上面 3 个变量值 就能使用
AccessKey 获取方式 登录阿里云-进入控制台-右上角头像-AccessKey
机器 ID 就是 ecs 的 id
然后在/var/spool/cron/root 里添加
