onWebSocketConnect和Events::onConnect访问顺序的问题

$gateway->onConnect = function($connection)
{
    $connection->onWebSocketConnect = function($connection)
    {
        echo 'onWebSocketConnect ',microtime(true),PHP_EOL;
     };
};

  public static function onConnect($client_id) {
        if (!Gateway::isOnline($client_id)) { //不在线直接则停止
            echo $client_id,'connect offline!--',microtime(true),PHP_EOL;
            return;
        }
    }
