python3实现UDP协议的服务器和客户端

from socket import *host = '192.168.48.128' # 这是客户端的电脑的ipport = 13141 #接口选择大于10000的，避免冲突bufsize = 1024 #定义缓冲大小addr = (host,port) # 元祖形式udpClient = socket(AF_INET,SOCK_DGRAM) #创建客户端while True:  data = input('>>> ')  if not data:    break  data = data.encode(encoding="utf-8")   udpClient.sendto(data,addr) # 发送数据  data,addr = udpClient.recvfrom(bufsize) #接收数据和返回地址  print(data.decode(encoding="utf-8"),'from',addr)udpClient.close()

from socket import *from time import ctimehost = '' #监听所有的ipport = 13141 #接口必须一致bufsize = 1024addr = (host,port) udpServer = socket(AF_INET,SOCK_DGRAM)udpServer.bind(addr) #开始监听while True: print('Waiting for connection...') data,addr = udpServer.recvfrom(bufsize) #接收数据和返回地址 #处理数据 data = data.decode(encoding='utf-8').upper() data = "at %s :%s"%(ctime(),data) udpServer.sendto(data.encode(encoding='utf-8'),addr) #发送数据 print('...recevied from and return to :',addr)udpServer.close()
