tcp单独给用户发送数据，数据发现累积问题，

public  function sendMessageByUid($clientId, $message)
{
    global $worker;
    if(isset($worker->uidConnections))
    {
        Log::info('发送成功');

        $connection = $worker->uidConnections;
        Log::info($message);
        $connection->send($message,true);

    }else{

        Log::info('发送失败');

    }

}
