php实现钉钉业务报警机器人

使用场景，服务器报异常错误，想要及时收到报警信息并处理

环境介绍，本博使用yaf框架+php，仅仅提供思路，参考，具体根据自己实际情况进行编写

1，每十分钟执行一次任务脚本

# 每10分钟执行一次的任务
if [ "0" -eq "$(($minute % 10))" ]; then
  php -f ${pathRoot}public/index.php 'request_uri=/error/dingdingLog'
fi

2，先在钉钉pc端创建业务机器人
具体操作，参考：https://ding-doc.dingtalk.com/doc#/serverapi2/qf2nxq
我使用的是第三种方式，ip段

3，如果是已添加之后，复制链接
这是你需要群发消息的地址
https://oapi.dingtalk.com/robot/send?access_token=XXXXXX
4，php实现，捕获接口异常

/**
 * error action
 *
 * @return bool
 * @throws Exception
 */
public function errorAction()
{
    $req = $this->getRequest();
    $exception = $req->getException();
    //来自接口的错误
    if ($exception instanceof ApiException) {
        return $this->json($exception->getCode(), $exception->getMessage());
    }
    //其它异常
    if ($this->yafAutoRender) {
        $exceptions = [];
        if (! $exception instanceof Exception) {
            $exception = new Yaf\Exception\LoadFailed('no exception');
        }
        //add exception
        $exceptions[] = $exception;
        //show trace
        $this->getView()->exceptions = $exceptions;
        Yaf\Dispatcher::getInstance()->autoRender(true);
    } else {
        if ($exception instanceof Yaf\Exception\LoadFailed) { //接口不存在
            $this->log($exception, ApiException::NOT_EXISTS);
            return $this->json(ApiException::NOT_EXISTS, $exception->getMessage());
        }
        $this->log($exception);
        return $this->json(ApiException::FATAL, $exception->getMessage());
    }
}

5，修改框架错误日志log写入方法

 /**
 * error log
 *
 * @param Exception $exception
 * @param int $error_code 0-正常报错
 */
private function log($exception, $error_code = 0)
{
	//log exception
	$msg = sprintf("%s:%s. in %s on line %s, trace:%s",
		get_class($exception), 
		$exception->getMessage(), 
		$exception->getFile(), 
		$exception->getLine(),
        $exception->getTraceAsString()
    );

    // 排除 404 的报错才推送
    // there is not method / not such file or diractory
    if ($error_code != ApiException::NOT_EXISTS) {
        $this->saveLog($exception->getMessage());
    }
	LK::log()->error($msg);
 }

如上所示，我将一部分日志写入redis

6，保存日志

public function saveLog($msg)
{
    $redis = LK::redis('log');
    $key   = md5($msg);
    $saved = $redis->sadd('error_log', $key);
    if ($saved) {
        $redis->setex($key, 1100, $msg);
    }
    return $saved;
}

7，读取redis消息，给钉钉推送错误消息

public function dingdingLogAction()
{
    $redis = LK::redis('log');
    $keys  = $redis->sMembers('error_log');
    if (count($keys)) {
        foreach ($keys as $key) {
            if (false != ($msg = $redis->get($key))) {
                Func::dingdingLog($msg);
            }
        }
        $redis->del('error_log');
    }
}

8，curl上面那个地址，具体信息自行修改

 /**
 * 钉钉消息推送
 * 推到钉钉 php+web 群
 * @return bool
 */
public static function dingdingLog($msg)
{
    $url = 'https://oapi.dingtalk.com/robot/send?access_token=XXXXXX';
    $env = \Yaf\Application::app()->environ();
    $fix = 'somi';
    $time = date('Y-m-d H:i:s');
    $data = [
        'msgtype' => 'text',
        'text' => [
            'content' => "[{$fix}:{$env}:{$time}]:{$msg}",
        ]
    ];
    $data_string = json_encode($data);
    $resp = \Frame\Core\Tools::curl($url, 'POST', $data_string, ['Content-Type: application/json;charset=utf-8']);
    $resp = json_decode($resp, true);
    if ($resp['errorcode']) {
        return false;
    }
    return true;
}
