请问这里udp为什么报错 代码好像没有错

Question

import socket;
serversocket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM);
serversocket.bind(('127.0.0.1',8000));

while 1:
    data,address = serversocket.recv(1024)
    if not data:break


接收到对端发送的hello时，报如下错：
 

data,address = serversocket.recv(1024)
    ^^^^^^^^^^^^
ValueError: too many values to unpack (expected 2)

请问什么原因呢？

Answer 1

服务器端接收到的数据是一个元组

import socket
serversocket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
serversocket.bind(('127.0.0.1',8000))
while True:
    data,address = serversocket.recvfrom(1024)
    if not data:
        break
