Flask 邮件是否适用于 heroku

Question

flask mail works perfectly on my local host but it is failing to work on heroku. Below is my setup code


app.config['MAIL_SERVER'] = 'smtp.gmail.com'
app.config['MAIL_PORT'] = 587
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USERNAME'] = '@gmail.com'
app.config['MAIL_PASSWORD'] = '*****'

mail = Mail(app)



   @app.route("/mymessage" ,methods= ['POST','GET'])
    def mymessage():


    em = request.form['email']
    mm = request.form['message']
    msg = Message('Hello', sender = '@gmail.com', recipients = 
   ['@gmail.com'])
    msg.body = mm + " " + 'email address of  client :' + em
    mail.send(msg)
    flash("Message sent successful")  
    return redirect(url_for('home'))       
     


I get this error "2021-07-10T16:36:34.785576+00:00 app[web.1]: smtplib.SMTPAuthenticationError: (534, b'5.7.14 <https://accounts.google.com/signin/continue?sarp=1&scc=1&plt=AKgnsbs\n5.7.14 YJZzLi6GK2jMF6AunHXhEoSyz2r6fSOYLB4ABgjP0jNdTWHh3ig-fhlvwc7oxm-quoLVa\n5.7.14 Z7CHpvU2lMufxnPm_0Dsc3p1uWgZhenvZQpb2TdWaZTZ-Sg_wojgwf4zlOlBe44O>\n5.7.14 Please log in via your web browser and then try again.\n5.7.14  Learn more at\n5.7.14  https://support.google.com/mail/answer/78754 m6sm3480925qtx.9 - gsmtp')

Answer 1

Google 阻止您从 heroku 登录尝试。您需要启用 less secure apps 并为您的邮件帐户使用应用程序密码才能解决此问题。

首先我们必须启用 two step verification then only we can use the app password. After enabling the 2-step verification, go to app password 和 select 应用程序作为邮件和设备（我 selected windows 电脑）在你得到应用程序密码后替换你当前的密码。并再次尝试发送邮件。它会起作用。

app.config['MAIL_PASSWORD'] = 'your_app_password_here'
