前言

在日常生活中，我们可能会遇到某些异常发生后需要紧急通知到群里，让相关人员看到紧急处理的事件触发机制。 消息群我采用的是钉钉推送，本文介绍了如何用php 推送钉钉机器人消息。

源码封装

<?php
/*** 钉钉通知 - 签名版*/
class DingDingNoticeSign
{/*** 钉钉access_token 创建机器人时获得** @var string*/protected $accessToken;/*** 钉钉签名 类型为签名内容可获取** @var string*/protected $sign;public function __construct($accessToken,$sign){$this->accessToken = $accessToken;$this->sign = $sign;}public function sendMsg($msg){$this->sendDingMessage($this->structApiUrl(),$this->sign,$msg);}protected function generateSign($timestamp, $secret) {return urlencode(base64_encode(hash_hmac('sha256', $timestamp . "\n" . $secret, $secret, true)));}protected function sendDingMessage($webhookUrl, $secret, $message) {$timestamp = time() * 1000; // 当前时间戳$sign = $this->generateSign($timestamp, $secret); // 生成签名$headers = ['Content-Type: application/json;charset=utf-8;'];$body = json_encode(['msgtype' => 'text', // 消息类型，例如 text, markdown 等'text' => ['content' => $message // 消息内容]]);$webhookUrl.="&timestamp={$timestamp}&sign={$sign}";
//        dd($webhookUrl);$options = [CURLOPT_URL => $webhookUrl,CURLOPT_POST => true,CURLOPT_RETURNTRANSFER => true,CURLOPT_SSL_VERIFYPEER => false, // 注意：实际使用中应设置为 true 以增强安全性，此处为示例简化设置CURLOPT_POSTFIELDS => $body,CURLOPT_HTTPHEADER => $headers];$ch = curl_init();curl_setopt_array($ch, $options);$response = curl_exec($ch);
//        if ($response === false) {
            echo 'Curl error: ' . curl_error($ch);
//        } else {
            echo 'Response: ' . $response;
//        }curl_close($ch);}protected function structApiUrl(){$url = "https://oapi.dingtalk.com/robot/send";$query = ['access_token'  =>  $this->accessToken];$url = "{$url}?".http_build_query($query);return $url;}
}

如何使用？（见下文）

 //钉钉消息通知$accessToken = "xxxxxxxxxxxxxx";//access_token 创建机器人时获得的参数 get param中的access_token$sign = "xxxxxxxxxxxxx";//sign  选择为签名时获得的参数$dingdingService = new DingDingNoticeSign($accessToken,$sign);$dingdingService->sendMsg("我是消息通知");

很简单吧，内容封装好了，直接拿下来使用即可
