关于php:php封装实现钉钉机器人报警接口

本文次要讲述的是如何通过签名形式实现钉钉机器人报警的性能：

1、对于签名的生成：

    /**
     * 签名实现
     */
    list($s1, $s2) = explode(' ', microtime());
    $timestamp = (float)sprintf('%.0f', (floatval($s1) + floatval($s2)) * 1000);
    $secret = '****';
    $data = $timestamp . "\n" . $secret;
    $signStr = base64_encode(hash_hmac('sha256', $data, $secret,true));
    $signStr = utf8_encode(urlencode($signStr));
    $webhook = 'https://oapi.dingtalk.com/robot/send?access_token=****';
    $webhook .= "&timestamp=$timestamp&sign=$signStr";

2：应用 guzzle 申请接口，发送钉钉音讯

    /**
     * 发送钉钉报警
     */
    $guzzleClent = new \GuzzleHttp\Client();

    $data = [
        'msgtype' => 'text',
        'text' => ['content' => $msg,]
    ];

    $res = $guzzleClent->request('POST', $webhook,[
        'headers' => ['content-type' => 'application/json'],
        'body' => json_encode($data),
    ]);
    $res = json_decode($res->getBody());
    var_dump($res);
