从BitTrent的DHT引导中获得混乱的回复

Question

我正在尝试在Bittorrent主线中实现DHT节点。到目前为止，我在一个引导节点上进行了连接，根据一些已编码的示例，查询似乎很好但是我得到的结果的一部分都是乱码的（包含实际数据的部分）：

d2:ip6:µ§ û©Å1:rd2:id20:ëÿ6isQÿJì)Íº«òûãF|Âge1:t2:aa1:y1:re

到目前为止这是我的代码：

private static String serverName = "router.utorrent.com";
private static int port = 6881;
private static String packet = "d1:ad2:id20:abcdefghij0123456789e1:q4:ping1:t2:aa1:y1:qe";
public static void main(String[] args)  {

    int port = Main.port;
    InetAddress address = InetAddress.getByName(Main.serverName);
    DatagramSocket socket = new DatagramSocket();

    byte[] buf = Main.packet.getBytes();
    DatagramPacket packet = new DatagramPacket(buf, buf.length, address, port);
    socket.send(packet);
    byte[] recBuf = new byte[2048];
    DatagramPacket recPacket = new DatagramPacket(recBuf, recBuf.length);

    socket.receive(recPacket);

    System.out.println(new String(extract(recPacket)));
}

  private static byte[] extract(DatagramPacket packet) {
        byte[] data = packet.getData();
        int offset = packet.getOffset();
        int length = packet.getLength();

        byte[] copy = new byte[length];
        System.arraycopy(data, offset, copy, 0, copy.length);

        return copy;
      }

我不确定我是否有图表集问题，或者有一些我无法在任何地方找到的编码。
