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()
