网络编程-socket实现循环通信

import socket
phone=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
phone.bind((‘127.0.0.1‘,8080))
phone.listen(5)
conn,client_addr=phone.accept()
print(client_addr)
#通信循环
while True:
    data=conn.recv(1024)
    print("Client data:",data)
    conn.send(data.upper())
conn.close()

import socket
client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect((‘127.0.0.1‘,8080))
#通信循环
while True:
    msg=input(‘>> ‘).strip()
    client.send(msg.encode(‘utf-8‘))
    data=client.recv(1024)
    print(data)
#关闭连接
client.close()
