Question

我创建了一个简单的烧瓶服务器，在React中提交表单后，它将电子邮件发送到我的收件箱中。本地一切正常，但是当我想将flask服务器部署到heroku flask应用程序崩溃时。我创建一个包含web: gunicorn app:app的Procfile。然后，我用heroku create webapp然后用git push heroku master创建了一个heroku应用。

...
smtp = smtplib.SMTP(os.getenv('HOST'), os.getenv('PORT'))
smtp.connect(os.getenv('HOST'), os.getenv('PORT'))
smtp.starttls()

email = os.getenv('EMAIL')
sender = email
receivers = [email]

smtp.login(sender, os.getenv('EMAIL_PASSWORD'))


@app.route('/')
def index():
  return 'Hello'


@app.route('/email', methods=['POST'])
def email():
  if request.method == 'POST':
    data = request.get_json()
    subject = data['subject']
    msg = 'Subject: {}\n\n{}'.format(subject, data['message'])
    smtp.sendmail(sender, receivers, msg)
    return jsonify({
      'status': 200,
      'message': msg
    })
...

当我查看日志时，看到一个H10错误，这意味着App崩溃了。我的问题是为什么？
