python的网络编程笔记

一、

SOCK_STREAM:TCP

SOCK_Dgram    ：UDP

family = AF_INET

family=AF_UNIX

eg:

server:

import socket
from builtins import print, bytes, str

sk = socket.socket()
address = ('127.0.0.1',8000)
sk.bind(address)
sk.listen(3)
print('waitting.......')
conn,addr = sk.accept()
print('监听信息：',conn)
# conn.send(bytes('你好','utf8'))
print(conn.recv(1024))


二：









client:

import socket
from builtins import print, str, bytes

sk = socket.socket()
address = ('127.0.0.1',8000)
conn = sk.connect(address)
# data = sk.recv(1024)
# print(str(data,'utf8'))
sk.send(bytes('hello','utf8'))
