python3.5实现socket通讯示例(TCP）

import socket

import socketserver

import time

import threading

 

serverPort = 50007

serverSocket =socket.socket(socket.AF_INET,socket.SOCK_STREAM)

serverSocket.bind (('',serverPort))

serverSocket.listen(1)

print('The server is ready to receive')

while 1:

  connectionSocket,addr = serverSocket.accept()

  sentence = connectionSocket.recv(1024)

  capitalizedSentence = sentence.upper()

  connectionSocket.send(capitalizedSentence)

  connectionSocket.close() 

from socket import *

serverName = '127.0.0.1'

serverPort = 50007

clientSocket =socket(AF_INET,SOCK_STREAM)

clientSocket.connect((serverName,serverPort))

sentence = input('Input lowercase sentence:')

clientSocket.send(sentence.encode())

modifiedSentence = clientSocket.recv(1024)

print('From Server:',modifiedSentence.decode())

clientSocket.close()
