python Socket之客户端和服务端握手详解_Python

简单的学习下利用socket来建立客户端和服务端之间的连接并且发送数据

1. 客户端socketClient.py代码

									import socket 

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

									# 建立连接: 

									s.connect(('127.0.0.1', 9999)) 

									# 接收欢迎消息: 

									print(s.recv(1024).decode('utf-8')) 

									for data in [b'Michael', b'Tracy', b'Sarah']: 

									 # 发送数据: 

									 s.send(data) 

									 print(s.recv(1024).decode('utf-8')) 

									s.send(b'exit') 

									s.close()

2. 服务端serverSocket.py代码

									import socket 

									import threading 

									import time 

									# from threading import Thread 

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

									# 监听端口: 

									s.bind(('127.0.0.1', 9999)) 

									s.listen(5) 

									print('Waiting for connection...') 

									def tcplink(sock, addr): 

									 print('Accept new connection from %s:%s...' % addr) 

									 sock.send(b'Welcome!') 

									 while True: 

									  data = sock.recv(1024) 

									  time.sleep(1) 

									  if not data or data.decode('utf-8') == 'exit': 

									   break

									  sock.send(('Hello, %s!' % data.decode('utf-8')).encode('utf-8')) 

									 sock.close() 

									 print('Connection from %s:%s closed.' % addr) 

									while True: 

									 # 接受一个新连接: 

									 sock, addr = s.accept() 

									 # 创建新线程来处理TCP连接: 

									 t = threading.Thread(target=tcplink, args=(sock, addr)) 

									 t.start()
