阿里云上接受不到数据, 通过日志分析绝大多数错误是decode

我在krpc.go里添加了一些日志

func handle(dht *DHT, pkt packet) {
	if len(dht.workerTokens) == dht.PacketWorkerLimit {

		fmt.Println("return from len(dht.workerTokens) == dht.PacketWorkerLimit")
		return
	}

	dht.workerTokens <- struct{}{}

	go func() {
		defer func() {
			<-dht.workerTokens
		}()

		if dht.blackList.in(pkt.raddr.IP.String(), pkt.raddr.Port) {

			fmt.Println("return from dht.blackList.in(pkt.raddr.IP.String(), pkt.raddr.Port)")
			return
		}

		data, err := Decode(pkt.data)
		if err != nil {

			fmt.Print("return from data, err := Decode(pkt.data)")
			fmt.Println(err)
			return
		}

		response, err := parseMessage(data)
		if err != nil {

			fmt.Print("return from response, err := parseMessage(data)")
			fmt.Println(err)
			return
		}

		if f, ok := handlers[response["y"].(string)]; ok {
			f(dht, pkt.raddr, response)
		}
	}()
}

然后用如下命令进行日志过滤

grep "Got a response" nohup_dht.logs | wc -l
grep "return from data, err := Decode(pkt.data)" nohup_dht.logs | wc -l
grep "return from response, err := parseMessage(data)" nohup_dht.logs | wc -l
grep "return from dht.blackList.in(pkt.raddr.IP.String(), pkt.raddr.Port)" nohup_dht.logs| wc -l  

得到结果如下

0
620
10
22

运行了俩分钟绝大多数都是decode error

return from data, err := Decode(pkt.data)invalid bencode when decode item

一条有用的数据都没拿到.

请问是解码有问题吗?

PS, 是通过在mac上编译出的linux版本, 编译命令
