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。
