无法在Heroku上使用Gmail发送电子邮件 [英] Can't send email using Gmail on Heroku

问题描述

我无法使用Rails应用程序通过Gmail发送电子邮件。我可以在本地开发环境中发送电子邮件，但不能从Heroku发送电子邮件。
这是我的配置文件。

I can't get my Rails app to send emails using Gmail. I can send emails on my local development environment but I can't send it from Heroku. This is my config file.

application.rb

application.rb

  config.action_mailer.smtp_settings = {
    :address        => 'smtp.gmail.com',
    :domain         => 'gmail',
    :port           => 587,
    :user_name        => ENV['GMAIL_USERNAME'],
    :password         => ENV['GMAIL_PASSWORD'],
    :authentication     => 'login',
    :enable_starttls_auto => true
  }

我尝试了身份验证：登录和普通，但是没有也不行。我试过将此配置都放入application.rb和production.rb中，但没有用。我已经尝试使用域： my_my_name_on_heroku.com，但这也不起作用。我也尝试过 mail.google.com，但也没有运气。
我在Heroku上使用正确的用户名和密码设置了环境变量（确定为100％）。
我已启用安全性较差的应用程序，以使该应用程序在 https://myaccount.google.com/上运行lesssecureapps 。没有2要素身份验证。我已启用验证码，以允许通过 http://www.google.com/accounts/从不同设备登录。 DisplayUnlockCaptcha ，仍然没有电子邮件发送。

I have tried authentication: 'login' and 'plain' but that didn't work either. I have tried putting this config both into application.rb and production.rb and that didn't work. I've tried domain: "my_my_name_on_heroku.com" but that didn't work either. I have also tried 'mail.google.com' but no luck either. I have setup environment variables on Heroku with username and password properly (100% sure). I have enabled less secure apps to get the application working at https://myaccount.google.com/lesssecureapps. No 2-factor authentication. I have enabled captcha to allow to login from different devices at http://www.google.com/accounts/DisplayUnlockCaptcha and still no emails are sent.

在Heroku日志上，我看到它说正在发送电子邮件到...，它使模板很好，没有任何错误，但我没有收到任何电子邮件。我也检查了垃圾邮件文件夹，但那里没有电子邮件。

On Heroku logs I see that it says "Sending email to...", it renders the template fine, no errors whatsoever but I don't receive any emails. I've checked Spam folder as well but no emails there.

production.rb

production.rb

  config.action_mailer.default_url_options = { host: 'my_app.herokuapp.com' }
  config.action_mailer.perform_caching = false
  config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.raise_delivery_errors = false
  config.action_mailer.default :charset => "utf-8"

我缺少什么？

推荐答案

这是我永远拥有的活动应用程序，在该应用程序中邮件仍然有效。尝试将身份验证类型更改为符号而不是字符串。因此，：plain而不是 plain。

This is an active app I have had forever where the mail still works. Try changing the auth type to a symbol rather than a string. So :plain instead of 'plain'.

  config.action_mailer.smtp_settings = {
    :enable_starttls_auto => true,
    :address => 'smtp.gmail.com',
    :port => 587,
    :authentication => :plain,
    :domain => 'blarg.com',
    :user_name => '[e-mail]',
    :password => 'password'
  }

 config.action_mailer.default_url_options = { :host => 'blarg.heroku.com' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default :charset => "utf-8"
