WebSocket connection to ' ws://0.0.0.0:19999/' failed: Invalid frame header

客户链接服务器的时候，第一次可以正常连上weboskcet，但是连上一会儿后会返回invalid frame header，客户端进行重连也一直是返回这个是什么问题。

创建webscoket代码

$worker = new Worker('websocket://0.0.0.0:19999');

$worker->count = 1;

$worker->onWorkerStart = function ($worker){

    $inner_text_worker =newWorker('text://0.0.0.0:10002');
    $inner_text_worker->onMessage=function($connection,$buffer){
        broadCast($buffer);
        $connection->send('ok');        //像发送消息的客户端回消息
    };
    $inner_text_worker->listen();
};

接收信息的代码

 $worker->onMessage = function ($connection, $data){
    global $worker;
    // 判断当前客户端是否已经验证,既是否设置了uid
    if(!isset($connection->uid))
    {
        // 没验证的话把第一个包当做uid（这里为了方便演示，没做真正的验证）
        $connection->uid = $data;

        $url "http://127.0.0.1/admin_api/Member/setOnlie";
        $dataList["id"] = $connection->uid;
        $dataList["online_status"] = 1;
        $list = send_post($url,$dataList);
        $worker->uidConnections[$connection->uid] =                 $connection;
        $connection->send($data);
        return;
    }
    else if($data == "ping")
    {
        echo "ping的连接id:  ".$connection->uid."  时间:".date("Y-m-d H:i:s")."\n";
        sendMessageByUid($connection->uid,"ping");
    }
    return;
};

关闭连接代码

     $worker->onClose = function ($connection){
     global $worker;
    if(isset($connection->uid)){

      $url "http://127.0.0.1/admin_api/Member/setOnlie";                    
        $dataList["id"] = $connection->uid;
        $dataList["online_status"] = 0;
        $list = send_post($url,$dataList);
        unset($worker->uidConnections[$connection->uid]);
    }
};
