python 網路程式設計

今天晚上學習了一下python的網路程式設計，實現了client向server傳送資料，server反饋資訊

python 3.3 版本

server ：

from socket import *

class tcpserver(object):
def __init__ (self, serverport):
self.serversocket = socket(af_inet, sock_stream)
self.serversocket.bind(('', int(serverport)))
self.serversocket.listen(5)
def run(self):
print('the server socket is ready...')
while true:
connectionsocket, addr = self.serversocket.accept()
try:
message = connectionsocket.recv(4096)
print('received messages:',message)
connectionsocket.send(message) 
except ioerror:
connectionsocket.send('404 not found')
connectionsocket.close()
connectionsocket.close()
self.serversocket.close()
if __name__ == '__main__':
server = tcpserver('20000')
server.run()

client：

import sys

import socket
import string
class tcpclient(object):
def __init__ (self, serverhost, serverport):
self.serverhost = serverhost
self.serverport = serverport
print(self.serverhost)
print(self.serverport)
while true:
clientsocket = socket.socket(socket.af_inet, socket.sock_stream)
clientsocket.connect((self.serverhost, int(self.serverport)))
print('connected to the server...')
str=input('please input string:')
clientsocket.send(str.encode())
responce = clientsocket.recv(4096)
print('received:', responce)
clientsocket.close()
if __name__  ==  "__main__":
client = tcpclient('10.22.73.16', '20000')
