Question

我正在使用flask-mail向用户发送包含新密码的电子邮件。我运行代码时不断收到IOError错误的文件描述符

print>>stderr, 'reply:', repr(line)
IOError: [Errno 9] Bad file descriptor

这是否与套接字和连接有关？如果需要，我可以发布完整的追溯

编辑完整追溯：

  window.removeEventListener('wheel', onwheel, false);
  window.removeEventListener('mousedown', ondown, false);

  function onwheel(e) {
    console.info('wheeled, e:', e);
  }

  function ondown(e) {
    console.info('downed, e:', e);
  }

  window.addEventListener('wheel', onwheel, false);
  window.addEventListener('mousedown', ondown, false);

如果不起作用，您可以随时使用yagmail：

import yagmail
yag = yagmail.SMTP(MAIL_USERNAME, MAIL_PASSWORD)
yag.send(to = e, contents = 'Your password is ' + hashedp)

首先使用pip install yagmail（或pip3 for python 3）安装它。

它具有很多功能，包括轻松发送HTML电子邮件（带回退），通过指向文件和无密码脚本进行附加。
