这篇文章主要介绍了Python3 socket同步通信功能,结合简单实例形式分析了Python socket同步通信客户端与服务器端实现技巧,需要的朋友可以参考下
本文实例讲述了Python3 socket同步通信。分享给大家供大家参考,具体如下:
本文比较简单,适合入门用,作个笔记,方便日后抄写
一个服务端,一个客户端,而且是阻塞方式,一次只能接受一个客户端连接并通信噢。
客户端发送‘bye', 结束与服务端的通信,如果发送'shutdown',服务端将会关闭自己!
服务端代码:
from socket import * from time import ctime HOST = '' PORT = 21567 BUFSIZE = 1024 ADDR = (HOST, PORT) tcpSerSock = socket(AF_INET, SOCK_STREAM) tcpSerSock.bind(ADDR) tcpSerSock.listen(5) quit = False shutdown = False while True: print('waiting for connection...') tcpCliSock, addr = tcpSerSock.accept() print('...connected from: ', addr) while True: data = tcpCliSock.recv(BUFSIZE) data = data.decode('utf8') if not data: break ss = '[%s] %s' %(ctime(), data) tcpCliSock.send(ss.encode('utf8')) print(ss) if data == 'bye': quit = True break elif data == 'shutdown': shutdown = True break print('Bye-bye: [%s: %d]' %(addr[0], addr[1])) tcpCliSock.close() if shutdown: break tcpSerSock.close() print('Server has been
客户端代码:
from socket import * HOST = 'localhost' PORT = 21567 BUFSIZE = 1024 ADDR = (HOST, PORT) tcpCliSock = socket(AF_INET, SOCK_STREAM) tcpCliSock.connect(ADDR) while True: data = input('>') if not data: continue print('input data: [%s]' %data) tcpCliSock.send(data.encode('utf8')) rdata = tcpCliSock.recv(BUFSIZE) if not rdata: break print(rdata.decode('utf8')) if data == 'bye' or data == 'shutdown': break tcpCliSock.close()
