Heroku/Rails应用程序错误
问题描述：
我真的被困在这里，担心我的邮件配置文件都搞砸了。我的应用似乎在本地很好地工作，我在Nitrous上。我可以推动heroku大师罚款，当打开可以查看主页，这只是一种形式（https://nameless-taiga-1654.herokuapp.com/），但是一旦我点击提交，我收到一条错误消息。我相信我的所有邮件行为都是正确设置的，我打算通过heroku使用sendgrid来运行邮件的事情。基本上我只是迷路了，需要帮助。附件是表单错误的heroku日志。Heroku/Rails应用程序错误

尝试设置在production.rb文件中的以下内容：
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.default_url_options = { host: 'nameless-taiga-1654.herokuapp.com' }
另外，要验证配置是否正确，可以运行heroku config。

我和我目前的项目有同样的问题。事实上，正如我发现的那样，这是一个Gmail身份验证问题。您的应用正尝试登录Gmail帐户，但无法执行此操作，因为Gmail未查看或识别加密的电子邮件和密码。我通过编写必要的值到我smtp_settings直接，就像暂时解决了这个问题：
smtp_settings = {
...
:user_name => "...your gmail email...",
:password => "...your gmail password...",
...
}
另外，我改变了Gmail帐户的安全设置：关闭双重认证，并允许通过安全性较低的应用程序来访问我的帐户。所以，目前该应用程序已部署在Heroku上并正在运行。然而，从网络安全的角度来看，我的解决方案相当危险，所以我仍然在寻找更好的解决方案。
EDITED !!! 有一个更好的方法来加密Gmail帐户设置。在我的 。在.bashrc文件（隐藏在电脑的根目录 - 按Ctrl + H透露）我写了下面的代码行：
export GMAIL_NAME=necessary value here
export GMAIL_PASSWORD=necessary value here
这个我也改变了我的smtp_settings一个更多的时间，像后：
smtp_settings = {
...
user_name: ENV['GMAIL_NAME'],
password: ENV['GMAIL_PASSWORD'],
...
}
最后，我通过添加两个新变量GMAIL_NAME和GMAIL_PASSWORD以及必要的值，在Heroku：Heroku/Personal apps/myApp/Settings配置回购设置，“配置变量”部分。
它工作。
