用Python写一个模拟qq聊天小程序的代码实例

python/' target='_blank'>python 超简单的聊天程序

客户端:

import socket, syshost = '10.248.27.23'# host = raw_input("Plz imput destination IP:")# data = raw_input("Plz imput what you want to submit:")port = 51423s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)try:  s.connect((host, port))except socket.gaierror, e:  print "Address-related error connecting to server: %s" %e  sys.exit(1)except socket.error, e:  print "Connection error: %s" %e  sys.exit(1)while 1:  try:    data = raw_input("I say: ")    s.send(data)    buf = s.recv(1024)    if len(buf):      print "he say: "+buf  except:    print "Dialogue Over"    s.close()    sys.exit(0)

服务器:

import socket, traceback, syshost = ''port = 51423s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)s.bind((host, port))s.listen(1)ClientSock, ClientAddr = s.accept()while 1:  try:    buf = ClientSock.recv(1024)    if len(buf):      print "he say: "+buf    data = raw_input("I say: ")    ClientSock.sendall(data)  except:    print "Dialogue Over"    ClientSock.close()    sys.exit(0)

模拟qq聊天，语言环境：Python3

示例代码：

# 编写一个程序，模拟qq聊天# 要求：程序可以同时发消息和收消息，发和收的过程中程序不退出# 思路：使用socket来完成(socket 是全双工模式，可以实现收和发同时进行)，定义俩个线程，一个负责发消息、一个负责收消息from threading import Threadfrom socket import *def rec_data():  while True:    rec_info = udpsocket.recvfrom(1024)    print("\r>>%s:%s" % (rec_info[1], rec_info[0].decode("gb2312")))    print("<<", end="")def send_date():  while True:    send_mes = input("<<")    udpsocket.sendto(send_mes.encode("gb2312"), (desip, desport))udpsocket = Nonedesip = ""desport = 0def main():  global udpsocket  global desip  global desport  desip = input("对方IP：")  desport = int(input("对方端口："))  udpsocket = socket(AF_INET, SOCK_DGRAM)  udpsocket.bind(("", 9001))  tr = Thread(target=rec_data)  ts = Thread(target=send_date)  tr.start()  ts.start()  tr.join()  ts.join()if __name__ == '__main__':  main()
