前言

业务场景：监控当前业务当出现并发情况时技术人员可以可以及时处理

使用技术栈： laravel+redis

半小时触发一次报警信息实现思路

1、xshell脚本 

具体参数就不详细解释了，想要详细了解可以自行百度

curl -H "Content-Type:application/json" -H "connection:Keep-Alive" -s -X Post "预警接口"

2、laravel 任务调度

任务调度 | 综合话题 |《Laravel 5.6 中文文档 5.6》| Laravel China 社区 (learnku.com)

定时任务

现在Kernel 文件书写定时任务，定时任务名称需要上下一致

预警逻辑

在Commands 中书写该逻辑

当预警人数占当前时段总人数35% 时触发钉钉预警 该逻辑 根据业务自行书写

钉钉预警实现思路

1、获取token和secret

保存后会获得 webhookurl 与 secret

2、书写逻辑

<?php
namespace App\Extend\Qy\Ding\Qy;

use Illuminate\Support\Facades\Log;


/**
 * 钉钉发送消息
 */
class DingListen
{
    //token
//    public $listenToken = "d3dfd656c95f7d319090bb9a51423cd0a948e7b26ce71a6042c4313469e654f4"; //线上机器人token
    public $listenToken = "f1112c52be54005e3f2c58f5bf610555f0fc655fb1cafb005e6242f66ca918a3";  //测试机器人token
    //secret
//    public $listenSecret = "SEC8c7d7a0cf2ecd150790004648be4a05ee39ab11cfecca4b96ceca23c8ab56260"; //线上机器人secret
    public $listenSecret = "SEC800bc05ded1461939ab7b46d0efa2a97cdc8c379ec29e89600a0753eef486527";  // 测试机器人secret
    /**
     * 请求地址
     * @var string $url
     * */
    public $url = 'https://oapi.dingtalk.com/robot/send';

    /**
     * 请求地址
     * @var string $timestamp 13位毫秒级
     * */
    public $timestamp;

    /**
     * 加签
     * @var string $sign
     * */
    public $sign;

    /**
     * webhookurl
     * @var string $webhookurl
     * */
    public $webhookurl;


    public function __construct(){
        //时间戳
        $this->timestamp = time() * 1000;
        //加签
        $str = $this->timestamp."\n". $this->listenSecret;
        $sign =  hash_hmac("sha256",$str ,$this->listenSecret,true);
        $sign = base64_encode($sign);
        $this->sign = $sign ;
        //返回链接
        $webhookurl = $this->url.'?access_token='.$this->listenToken. '&timestamp='.$this->timestamp.'&sign='.urlencode($this->sign);
        $this->webhookurl = $webhookurl;
    }



    //发送text文本信息
    public function text($content = '', $mobiles = [], $userIds = [], $isAtAll = true)
    {
        $sendContent = [
            "msgtype" => "text",
            "text" => [
                "content" => $content
            ],
            "at" => [
                "atMobiles" => $mobiles,
                "atUserIds" => $userIds,   //不是钉钉管理员无法获取userIds
                "isAtAll" => $isAtAll
            ]
        ];
        $res = $this->_curl_post_json($this->webhookurl, $sendContent);
        return $res;
    }

    //发送json数据
    public function _curl_post_json($url, $data = array())
    {
        $curl = curl_init($url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 5);
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data, 320));
        curl_setopt($curl, CURLOPT_HEADER, 0);
        curl_setopt($curl, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $res = curl_exec($curl);
        curl_close($curl);
        return $res;
    }
}

也可以将上述配置文件封装到Cofig 配置文件 自行调用 实例只发送了text 文本消息 具体案例信息查看官方文档进行配置 本文章仅限提供思路
