双十一期间要做活动，设置商品请求限流，护航秒杀活动正常进行！#设置1秒内最多同时1000请求
$maxNum = 1000;
$redisKey = 'GoldMall:Huodong:gid'.$g_id.'_'.date('s');
$onlineNum = (int)$this->redis->get($redisKey);
if($onlineNum){$onlineNum++;$this->redis->set($redisKey,$onlineNum,1);
}else{$onlineNum = 1;$this->redis->set($redisKey,$onlineNum,1);
}
if($onlineNum>$maxNum){$this->jsonResponse(401,"服务器繁忙请稍后再试~{$onlineNum}");
}

以上代码经过实践测试，OK的！
