如何从邮件中获取动态口令并在文本字段上打印？

import poplib
from email.parser import Parser

# 邮件服务器信息
pop3_server = 'pop.example.com'
username = 'your_email@example.com'
password = 'your_password'

# 连接到邮件服务器
server = poplib.POP3(pop3_server)
server.user(username)
server.pass_(password)

# 获取邮件列表
resp, mails, octets = server.list()

# 获取最新一封邮件
latest_mail_index = len(mails)
resp, lines, octets = server.retr(latest_mail_index)

# 解析邮件内容
msg_content = b'\r\n'.join(lines).decode('utf-8')
msg = Parser().parsestr(msg_content)

# 提取动态口令
dynamic_password = None
for part in msg.walk():
    if part.get_content_type() == 'text/plain':
        dynamic_password = part.get_payload(decode=True).decode('utf-8')
        break

# 关闭连接
server.quit()

# 打印动态口令
if dynamic_password:
    print("动态口令：", dynamic_password)
else:
    print("未找到动态口令")

<input type="text" id="dynamic-password-field" readonly>

// 获取动态口令
var dynamicPassword = "123456";

// 将动态口令填充到文本字段
document.getElementById("dynamic-password-field").value = dynamicPassword;
