Heroku/Rails應用程序錯誤

我真的被困在這裏，擔心我的郵件配置文件都搞砸了。我的應用似乎在本地很好地工作，我在Nitrous上。我可以推動heroku大師罰款，當打開可以查看主頁，這只是一種形式（https://nameless-taiga-1654.herokuapp.com/），但是一旦我點擊提交，我收到一條錯誤消息。我相信我的所有郵件行爲都是正確設置的，我打算通過heroku使用sendgrid來運行郵件的事情。基本上我只是迷路了，需要幫助。附件是表單錯誤的heroku日誌。Heroku/Rails應用程序錯誤

檢查你的'config.action_mailer.smtp_settings'生產。 – alexsmn

@alexsmn我剛剛將設置文件複製到原始問題中。我真的迷失在這裏，太令人沮喪了！ – RuNpiXelruN

嘗試設置在production.rb文件中的以下內容：

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，要驗證配置是否正確，可以運行heroku config。

我和我目前的項目有同樣的問題。事實上，正如我發現的那樣，這是一個Gmail身份驗證問題。您的應用正嘗試登錄Gmail帳戶，但無法執行此操作，因爲Gmail未查看或識別加密的電子郵件和密碼。我通過編寫必要的值到我smtp_settings直接，就像暫時解決了這個問題：

smtp_settings = { 
     ... 
     :user_name => "...your gmail email...", 
     :password => "...your gmail password...", 
     ... 
    }

另外，我改變了Gmail帳戶的安全設置：關閉雙重認證，並允許通過安全性較低的應用程序來訪問我的帳戶。所以，目前該應用程序已部署在Heroku上並正在運行。然而，從網絡安全的角度來看，我的解決方案相當危險，所以我仍然在尋找更好的解決方案。

EDITED !!! 有一個更好的方法來加密Gmail帳戶設置。在我的。在.bashrc文件（隱藏在電腦的根目錄 - 按Ctrl + H透露）我寫了下面的代碼行：

export GMAIL_NAME=necessary value here 
    export GMAIL_PASSWORD=necessary value here

這個我也改變了我的smtp_settings一個更多的時間，像後：

smtp_settings = { 
     ... 
     user_name: ENV['GMAIL_NAME'], 
     password: ENV['GMAIL_PASSWORD'], 
     ... 
    }

最後，我通過添加兩個新變量GMAIL_NAME和GMAIL_PASSWORD以及必要的值，在Heroku：Heroku/Personal apps/myApp/Settings配置回購設置，「配置變量」部分。

它工作。
