python学习笔记(45) socket

socket(套接字)是一组接口，一个模块，是ip加port

基于文件类型的套接字家族：AF_UNIX

基于网络类型的套接字家族：AF_INET(ipv4)

SEVER:

import socket
from socket import SOL_SOCKET,SO_REUSEADDR
sk = socket.socket()
sk.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)  #避免重启服务器的时候报地址被占用
sk.bind((‘127.0.0.1‘,8080))   #(ip,port)
sk.listen()
conn,addr = sk.accept()
print(addr)
while True:
    ret = conn.recv(1024).decode(‘utf-8‘)
    print(ret)
    if ret == ‘bye‘:
        conn.send(b‘bye‘)
        break
    info = input(‘>>>‘)
    conn.send(bytes(info,encoding=‘utf-8‘))

conn.close()
sk.close()

CLIENT:

import socket
sk = socket.socket()
sk.connect((‘127.0.0.1‘,8080))

while True:
    info = input(‘>>>‘)
    sk.send(bytes(info,encoding=‘utf-8‘))
    ret = sk.recv(1024).decode(‘utf-8‘)
    print(ret)
    if ret == ‘bye‘:
        sk.send(b‘bye‘)
        break
sk.close()
