python 网络编程

今天晚上学习了一下python的网络编程，实现了client向server发送数据，server反馈信息

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')

上面的ip和端口自己设置就可以了，本来我是想把client发送消息部分的代码放在run函数里的，但是编译始终报错，无语了，那就将就用吧。测试通过可以运行。
