    pkg.setData(res.data);

    var packageID = pkg.getPackageID();

    dictionaryClient[packageID]();
};

var dictionaryClient = {};
dictionaryClient[clientPacketID.ping] = ping;

function ping() {
    console.log("PING");

    pkg.setPackageID(serverPacketID.pong);
    ws.send(pkg.dataSend());
}

var clientPacketID = {
    ping: 1
};

var serverPacketID = {
    pong: 1
};

ws.on('connection', function(ws) {
