Heroku 环境中的 Ruby on Rails 应用程序：“使用 Mailgun 发送电子邮件”错误

【中文标题】Heroku 环境中的 Ruby on Rails 应用程序：“使用 Mailgun 发送电子邮件”错误【英文标题】：Ruby on Rails app on a Heroku environment: "Sending Email with Mailgun" error 【发布时间】：2017-07-15 20:06:17 【问题描述】：

我试图测试从基于 Heroku 服务器的 Rails 应用程序的联系表单发送电子邮件，我收到一条错误消息：

很抱歉，出了点问题。如果您是应用程序所有者，请查看日志以获取更多信息。

我的目的是学习如何将邮件服务器服务集成到我的 Heroku 帐户中。为此，使用的插件是 MailGun。我什至用我的个人电子邮件创建了一个 MailGun 帐户，以便能够检查我是否收到了电子邮件。

在成功将代码从 Cloud9 环境部署到 Heroku 服务器后，我对 Ruby 代码所做的唯一更改是以下内容：

config/environment.rb

ActionMailer::Base.smtp_settings = 
  :port           => ENV['MAILGUN_SMTP_PORT'],
  :address        => ENV['MAILGUN_SMTP_SERVER'],
  :user_name      => ENV['MAILGUN_SMTP_LOGIN'],
  :password       => ENV['MAILGUN_SMTP_PASSWORD'],
  :domain         => 'blahblahblah.herokuapp.com',
  :authentication => :plain,

ActionMailer::Base.delivery_method = :smtp

有什么问题？有什么解决办法吗？

更新的请求信息（Heroku 日志 - 由于 *** 正文中的字符限制，我无法更新所有日志）：

【问题讨论】：

请通过在命令外壳的应用目录中运行 heroku 日志来发布日志 如果您的配置有问题请检查，如果您的 Rails 代码有问题，请同时发布该代码 @KcUS_unico 你好，当我做“heroku 日志”时，我收到了很多东西……我什至不知道从什么地方开始复制。我将在收到错误后从日志中复制一份，同时，您希望查看代码中的哪一部分。任何特定的控制器、邮件程序或其他任何东西？ 请张贴整个heroku日志.. heroku 日志发布 【参考方案1】：

阅读错误信息：

Net::SMTPFatalError (554 Please activate your Mailgun account. Check your inbox or log in to your control panel to resend the activation email.

只需激活您的帐户。

【讨论】：

该帐户从一开始就已激活，因为它显示“看起来此帐户已被激活”。但是，它仍然不起作用。当我要求重新发送激活时，我从 MailGun 收到“服务器错误/发生内部服务器错误”。无论如何感谢您的帮助。 抱歉没用。不幸的是，这些日志只说该帐户未激活。 Sendgrid 是另一个邮件提供商，它也提供免费计划，并且与 heroku 配合得很好。【参考方案2】：

好的。正如日志所说，正如@GrahamSlick 已经回答的那样，您的mailgun 帐户未经过验证。如果您声称该帐户已通过验证，请确保您使用的凭据 您的 config/environment.rb 是属于已验证帐户的正确帐户，并确保 heroku 使用正确的凭据。日志显示您的帐户未经过验证。可能您想再次使用 mailgun 检查您的设置，看看它们是否告诉您有关拥有非活动帐户的信息。祝你好运。

您必须添加一个域，验证它，然后您才能从 mailgun 发送邮件。

【讨论】：

如果您已经添加了域但仍然无法使用，那么您可以在 mailgun 支持上添加票证以进行验证。【参考方案4】：

我遇到了完全相同的问题。我什至尝试只使用 CURL 以确保它与 rails 或 heroku 无关。我仔细检查了我的域是否经过验证。

我最终打开了一张支持票。他们在几个小时内回复了我并说“现在可以开始了”，果然成功了。

因此，要么是他们的错误，要么是他们故意要求对某些帐户进行人工监督。第一印象不是很好，但很高兴看到他们的支持迅速得到响应。
