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()
