python客户端和服务端_pythonSocket之客户端和服务端握手详解

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 &＃61; socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 建立连接:

s.connect((&＃39;127.0.0.1&＃39;, 9999))

# 接收欢迎消息:

print(s.recv(1024).decode(&＃39;utf-8&＃39;))

for data in [b&＃39;Michael&＃39;, b&＃39;Tracy&＃39;, b&＃39;Sarah&＃39;]:

# 发送数据:

s.send(data)

print(s.recv(1024).decode(&＃39;utf-8&＃39;))

s.send(b&＃39;exit&＃39;)

s.close()

2. 服务端serverSocket.py代码

import socket

import threading

import time

# from threading import Thread

s &＃61; socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 监听端口:

s.bind((&＃39;127.0.0.1&＃39;, 9999))

s.listen(5)

print(&＃39;Waiting for connection...&＃39;)

def tcplink(sock, addr):

print(&＃39;Accept new connection from %s:%s...&＃39; % addr)

sock.send(b&＃39;Welcome!&＃39;)

while True:

data &＃61; sock.recv(1024)

time.sleep(1)

if not data or data.decode(&＃39;utf-8&＃39;) &＃61;&＃61; &＃39;exit&＃39;:

break

sock.send((&＃39;Hello, %s!&＃39; % data.decode(&＃39;utf-8&＃39;)).encode(&＃39;utf-8&＃39;))

sock.close()

print(&＃39;Connection from %s:%s closed.&＃39; % addr)

while True:

# 接受一个新连接:

sock, addr &＃61; s.accept()

# 创建新线程来处理TCP连接:

t &＃61; threading.Thread(target&＃61;tcplink, args&＃61;(sock, addr))

t.start()

3.操作过程

开两个控制台窗口&＃xff0c;先运行服务端 python3 serverSocket.py

然后运行客户端 python3 socketClient.py
