python网络编程三要素:网络地址,端口号,协议
知识点:conn代表的是客户端的socket对象.
下面的server.py和client.py小程序,实现了最简单的socket通信功能.
#server.py import socket sk = socket.socket() address = (‘127.0.0.1‘,8080) sk.bind(address) sk.listen(3) print(‘waitting......‘) conn,addr = sk.accept() inp = input(‘>>>>>>‘) conn.send(bytes(inp,‘utf8‘)) data = conn.recv(1024) print(data) sk.close()
import socket sk = socket.socket() address = (‘127.0.0.1‘,8080) sk.connect(address) data = sk.recv(1024) print(data) sk.send(bytes(‘You are stupid‘,‘utf8‘))
server.py运行结果:
/usr/bin/python3.6 /home/guoming/python/day26/server.py
waitting......
>>>>>>hello
b‘You are stupid‘
Process finished with exit code 0
client.py运行结果:
/usr/bin/python3.6 /home/guoming/python/day26/client.py
b‘hello‘
Process finished with exit code 0
