TCPServer+BaseRequestHandler网络编程

注意：

通过self.request.recv()和self.request.send()两个函数来接受和发送消息；

服务器端代码：

from socketserver import (TCPServer, BaseRequestHandler)
from time import ctime

HOST = ''
PORT = 12345
ADDR = (HOST, PORT)
BUFSIZE = 1024

class MyHandler(BaseRequestHandler):
    def handle(self):
        print('connected from:', self.client_address)
        data = '[%s]%s' % (ctime(), self.request.recv(BUFSIZE).decode('UTF-8'))
        self.request.send(bytes(data, 'UTF-8'))

tcpSer = TCPServer(ADDR, MyHandler)
print('...waiting fo connection...')
tcpSer.serve_forever()

客户端代码：

from socket import *

HOST = 'localhost'
PORT = 12345
ADDR = (HOST, PORT)
BUFSIZE = 1024

def main():
    while True:
        tcpCliSock = socket(AF_INET, SOCK_STREAM)
        tcpCliSock.connect(ADDR)
        data = input('>')
        if not data:
            break;
        tcpCliSock.send(bytes(data + '\r\n', 'UTF-8'))
        data = tcpCliSock.recv(BUFSIZE).decode('UTF-8')
        if not data:
            break;
        print (data)
        tcpCliSock.close()

main()
