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 sysimport socketimport stringclass 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。
