客户端服务端循环收发消息

Posted 2021-12-19 jintian

from socket import *　　不用每次调用加socket

tcp_server=socket(AF_INET,SOCK_STREAM)

收发消息是字节格式

import socket
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
phone.bind((‘192.168.1.6‘,8002))
phone.listen(5)
print(‘------>‘)
conn,addr=phone.accept()
while True:
    msg=conn.recv(1024)
    print(type(msg))
    print(‘来自客户端的消息‘,msg.decode(‘utf-8‘))
    conn.send(msg.upper())
conn.close()
phone.close()

服务端循环收发消息

import socket
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
phone.connect((‘192.168.1.6‘,8002))
while True:
    msg=input(‘>>:‘).strip()
    if not msg: continue
    phone.send(msg.encode(‘utf-8‘))
    print(123)
    data=phone.recv(1024)
    print(‘来自服务端的消息‘,data.decode(‘utf-8‘))
phone.close()
