【9.2】client和server实现通信

server

 1 #!/usr/bin/env python
 2 # -*- coding:utf-8 -*-
 3 
 4 import socket
 5 
 6 # AF_INET IPv4 SOCK_STREAM TCP协议
 7 server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 8 server.bind(('0.0.0.0', 7777))
 9 server.listen()
10 sock, addr = server.accept()
11 
12 # 获取从客户端发送的数据，一次获取1K的数据
13 data = sock.recv(1024)
14 print(data.decode('utf-8'))
15 sock.send('hello {}'.format(data.decode('utf-8')).encode('utf-8'))
16 sock.close()
17 server.close()

client

 1 #!/usr/bin/env python
 2 # -*- coding:utf-8 -*-
 3 
 4 import socket
 5 
 6 
 7 client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 8 client.connect(('127.0.0.1',7777))
 9 client.send('zy'.encode('utf-8'))
10 data = client.recv(1024)
11 print(data.decode('utf-8'))
12 client.close()

server

zy

client

hello zy
