python之套接字小练习

编写远程执行命令的CS架构软件

客户端

import socket

cmd_user = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

cmd_user.connect(('127.0.0.1',8080))

while True:
    cmd = input('cmd:>>').strip()
    if len(cmd) == 0:
        continue
    cmd_user.send(cmd.encode('utf-8'))
    respond = cmd_user.recv(1024)
    print(respond.decode('utf-8'))

cmd_user.close()

服务端

import socket

cmd_user = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
cmd_user.bind(('127.0.0.1',8080))
cmd_user.listen(5)
while True:
    conn,client_addr = cmd_user.accept()
    while True:
        try:
            cmd = conn.recv(2048)
            if len(cmd) == 0:
                break
            exec(cmd)
            print(执行成功！')
            conn.send(f'{cmd}执行成功'.encode('utf-8'))
        except Exception:
            break
    conn.close()
cmd_user.close()
