问题描述

lnmp高并发情况下出现TP5中的函数重复执行

问题出现的环境背景及自己尝试过哪些方法

已经使用cache作为判断标准，限制一段时间内就算函数执行，也保证数据不会入库。

相关代码

php代码：

 public function winprize()
{
    if (Request::instance()->isPost()){
        $openid=Cookie::get('hzz_openid');
        $win_type=db('winprize')->where('openid',$openid)->where('state',0)->field('type')->find();
        if($win_type){
            if($win_type['type']==0){
                return json(['code'=>4,'msg'=>'存在记录']);
            }else{
                return json(['code'=>5,'msg'=>'不存在的记录']);
            }
        }
        $user_id=input('id');
        $user=db('user')->where('id',$user_id)->find();
        if($user['number']<$user['max_number']){
            if($user['max_number']>2){
                $fact_assist=db('assist')->where('openid_ass',$openid)->count();
                if($fact_assist<(5*$user['max_number'])){
              db('assist')->where('openid_ass',$openid)->update(['max_number'=>floor($fact_assist/5)]);
                    return json(['code'=>2,'msg'=>'无效的']);
                }
            }
            $jackpot=db('jackpot')->where('state',1)->find();

            $data['user_id']=$user['id'];
            $data['openid']=$user['openid'];
            $data['create_time']=time();
            if($jackpot['type']==0){
                if(!empty($user['redpack_openid'])){
                    $data['redpack_openid']=$user['redpack_openid'];}
                $data['price']=$jackpot['price'];

            try{
                db('jackpot')->where('id',$jackpot['id'])->update(['state'=>0]);
                db('user')->where('openid',$openid)->update(['number'=>$user['number']+1]);
                db('winprize')->insert($data);
                Db::commit();
                return json(['code'=>0,'type'=>$jackpot['type']]);
            } catch (\Exception $e) {

                Db::rollback();
                return json(['code'=>3,'msg'=>'事务出现异常！']);}
        }else{
            return json(['code'=>1,'msg'=>'没有抽奖机会']);}
    }
    return json(['code'=>-1,'msg'=>'错误']);

查阅了一下nginx与php错误日志，没有发现有异常记录。请大神帮忙分析一下
