#教程# 阿里云国际 – 流量包脚本监控 超流量自动关机

前言

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。

解决方法

把下面的文件保存为 datamonitoring.php

<?php
error_reporting(0);
        $AccessKey_ID='xxxxxxxxxxxx';//AccessKey_ID
        $Access_Key_Secret='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';//Access_Key_Secret
        $InstanceId='i-t4naxxxxxx';//需要关机的 ecsID
       
    function percentEncode($str){
        // 使用 urlencode 编码后，将"+","*","%7E"做替换即满足 ECS API 规定的编码规范
        $res = urlencode($str);
        $res = preg_replace('/\+/', '%20', $res);
        $res = preg_replace('/\*/', '%2A', $res);
        $res = preg_replace('/%7E/', '~', $res);
        return $res;
    }
    function computeSignature($parameters, $accessKeySecret){
        // 将参数 Key 按字典顺序排序
        ksort($parameters);
        // 生成规范化请求字符串
        $canonicalizedQueryString = '';
        foreach($parameters as $key => $value)
        {
            $canonicalizedQueryString .= '&' . percentEncode($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;

        );
        $data = array_merge($publicdata,$data);
        $data['Signature'] = computeSignature($data, $Access_Key_Secret);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $host . http_build_query($data));
        curl_setopt($ch, CURLOPT_HEADER, 0);

                                        );
        
             $res = (string)get_action($data,'2017-12-14','https://business.ap-southeast-1.aliyuncs.com/?');
              //echo $res;
               $jsonarray = json_decode($res,true);
              if($jsonarray['Message']=='Successful!'){
                echo $jsonarray['Data']['Instances']['Instance'][0]['RemainingAmount'];
                if($jsonarray['Data']['Instances']['Instance'][0]['RemainingAmount']<=20){//这里判断流量小于 20G
                        StopInstance();
                }
        }

                                        );
        $res = (string)get_action($data,'2014-05-26','https://ecs.aliyuncs.com/?');

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
