recv是用户态的应用程序发起的

队列：是先进先出，吃了拉　　队栈：是先进后出，吃了吐

输入空重新输入用continue

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