【9.2】client和server实现通信

server

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import socket

# AF_INET IPv4 SOCK_STREAM TCP协议
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('0.0.0.0', 7777))
server.listen()
sock, addr = server.accept()

# 获取从客户端发送的数据，一次获取1K的数据
data = sock.recv(1024)
print(data.decode('utf-8'))
sock.send('hello {}'.format(data.decode('utf-8')).encode('utf-8'))
sock.close()
server.close()

client

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import socket


client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(('127.0.0.1',7777))
client.send('zy'.encode('utf-8'))
data = client.recv(1024)
print(data.decode('utf-8'))
client.close()

server

zy

　　

client
