tcp socket实现

[python]代码库

import threading
import time
import logging
import socket

logging.basicConfig(format='%(thread)s %(threadName)s %(message)s',level=logging.INFO)
#创建一个tcpserver对象
sock = socket.socket()   #1.创建一个tcpserver对象
ip = '127.0.0.1'
port = 9999
addr = (ip,port)
sock.bind(addr)  #2.绑定
sock.listen()  #3.监听
conn,addrinfo = sock.accept()  #4.接收消息，等待访问，阻塞状态

logging.info(conn)
logging.info(addrinfo)

data = conn.recv(1024)   #阻塞中，
logging.info(data.decode())
msg = 'ack {}'.format(data.decode())
conn.send(msg.encode())     #发送给客户端消息，data是字节

logging.info(sock)



conn.close()
sock.close()
