以下是客户端代码：

import socket

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(('172.26.79.123', 9999))

def register():
    # 处理注册请求
    username = input('Please enter your username: ')
    password = input('Please enter your password: ')
    client_socket.send('register'.encode())
    client_socket.send(username.encode())
    client_socket.send(password.encode())
    response = client_socket.recv(1024).decode()
    print(response)

def login():
    # 处理登录请求
    username = input('Please enter your username: ')
    password = input('Please enter your password: ')
    client_socket.send('login'.encode())
    client_socket.send(username.encode())
    client_socket.send(password.encode())
    response = client_socket.recv(1024).decode()
    print(response)

while True:
    action = input('Please enter an action (register/login): ')
    if action == 'register':
        register()
    elif action == 'login':
        login()
    else:
        print('Invalid action.')
