php不断的切换前端链接方法 防止攻击


swoole写法  每分钟生成一次url后缀 返回到客户端让他们更新
$ws->on('message', function ($ws, $frame) {
    var_dump($frame);
    $data = json_decode($frame->data, 'true');
    $tag = intval($data['tag']);

    /*初始化玩家信息和pc信息*/
    if ($tag == 1) {
        /*用户第一次加载初始化*/
        $data = array('fid' => $frame->fd);
        $isOk = commoninsertinfo($data, fid');
        if ($isOk) {
            $sql = 'select houzhui from urlhouzhui where id=1 limit 1';
            $houzhui = commongetinfo($sql)[0]['houzhui'];
            $ws->push($frame->fd, json_encode(array('success' => 1, 'msg' => '初始化成功', 'data' => array('tag' => $tag, 'list' => array('houzhui' => $houzhui)))));
        } else {
            $ws->push($frame->fd, json_encode(array('success' => 0, 'msg' => '请重新刷新页面', 'data' => array('tag' => $tag))));
        }
    }
});



//定时器要写在WorkerStart这个里面哦
$ws->on('WorkerStart', function ($serv, $worker_id) {
    /*1分钟更新一次url 防止ddos攻击*/
    swoole_timer_tick(60000, function ($timer_id) use ($serv) {
        $houzhui = getRandom(8, 1);
        commonupdateinfo(array('houzhui' => $houzhui), 'id', 1, 'urlhouzhui');
        $sql = 'select fid from fid';
        $fidlist = commongetinfo($sql);
        if (!empty($fidlist)) {
            foreach ($fidlist as $k => $v) {
                $serv->push($v['fid'], json_encode(array('success' => 1, 'msg' => '生成成功', 'data' => array('tag' => 1, 'list' => array('houzhui' => $houzhui)))));
            }
        }
    });
});





php这里也要更新  请求的接口地址也要读取数据库更新过来
  /*读取url后缀*/
        $sql = 'select houzhui from urlhouzhui where id=1 limit 1';
        $houzhui = $this->commongetinfo($sql)[0]['houzhui'];
        if (ACTION_NAME != "index" && ACTION_NAME != "huodongguize") {
            $pos = strpos(ACTION_NAME, strval($houzhui));
            if (!is_numeric($pos)) {
                if(isset($_SERVER["HTTP_X_REQUESTED_WITH"]) && strtolower($_SERVER["HTTP_X_REQUESTED_WITH"])=="xmlhttprequest"){
                    echo json_encode(array('success' => 0, 'msg' => '停留时间过长,你需要返回上个页面,并且进行刷新后进行操作'));
                    exit();
                }else{
                    header("Content-type:text/html;charset=utf-8");
                    echo "";
                    exit;
                };
            }else{
                $url=rtrim(ACTION_NAME,$houzhui);
                $this->$url();
                exit();
            }
        }
