python創建udp服務端和客戶端

1.udp服務端server

from socket import *
from time import ctime

HOST = ''
PORT = 8888
BUFSIZ = 1024
ADDR = (HOST, PORT)

udpSerSock = socket(AF_INET, SOCK_DGRAM)
udpSerSock.bind(ADDR)

while True:
    print('waiting for message...')
    data, addr = udpSerSock.recvfrom(BUFSIZ)

    content = '[%s] %s' % (bytes(ctime(), "utf-8"), data)
    udpSerSock.sendto(content.encode("utf-8"), addr)
    print('...received from and returned to:', addr)

udpSerSock.close()

 

 

 

2.udp客戶端client

from socket import *

HOST = 'localhost'
PORT = 8888
BUFSIZ = 1024
ADDR = (HOST, PORT)

udpCliSock = socket(AF_INET, SOCK_DGRAM)

while True:
    data = input('> ')
    if not data:
        break

    udpCliSock.sendto(data.encode("utf-8"), ADDR)
    data, ADDR = udpCliSock.recvfrom(BUFSIZ)
    if not data:
        break
    print(data)

udpCliSock.close()
