使用多线程、udp实现双工聊天

from threading import Thread
from socket import *


def recvData():
    while True:
        recvInfo = udpSocket.recvfrom(1024)
        print(">>%s:%s"%(str(recvInfo[1]),recvInfo[0].decode("gb2312")))


def sendData():
    while True:
        sendInfo = input("<<")
        udpSocket.sendto(sendInfo.encode("gb2312"),(destIp,destPort))


udpSocket = None
destIp = ""

def main():

    global udpSocket
    global destIp
    global destPort

    destIp = str(input("请输入对方的ip: "))
    destPort = int(input("请输入对方的port: "))

    udpSocket = socket(AF_INET,SOCK_DGRAM)
    udpSocket.bind(("",4567))

    tr = Thread(target=recvData)
    ts = Thread(target=sendData)

    tr.start()
    ts.start()

    tr.join()
