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()
