如何将额外的数据附加到用户(用于密码重置)

import random
import smtplib
from email.mime.text import MIMEText

def send_otp(email):
    otp = random.randint(100000, 999999)
    msg = MIMEText(f'Your OTP is: {otp}')
    msg['Subject'] = 'Password Reset OTP'
    msg['From'] = 'noreply@example.com'
    msg['To'] = email
    
    # 这里应配置SMTP服务器信息
    smtp_server = 'smtp.example.com'
    smtp_port = 587
    smtp_username = 'your_username'
    smtp_password = 'your_password'
    
    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()
        server.login(smtp_username, smtp_password)
        server.sendmail(smtp_username, [email], msg.as_string())
    return otp

def verify_otp(user_input_otp, sent_otp):
    return user_input_otp == sent_otp

# 使用示例
email = 'user@example.com'
sent_otp = send_otp(email)
user_input_otp = int(input("Enter OTP: "))
if verify_otp(user_input_otp, sent_otp):
    print("OTP verified. Proceed to reset password.")
else:
    print("Invalid OTP. Please try again.")
