用Python写一个模拟qq聊天小程序的代码实例

Python 超简单的聊天程序

客户端:

import socket, sys
host = '10.248.27.23'
# host = raw_input("Plz imput destination IP:")
# data = raw_input("Plz imput what you want to submit:")
port = 51423
s = 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, sys
host = ''
port = 51423
s = 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 Thread
from 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 = None
desip = ""
desport = 0
def 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()
