Heroku不使用Gmail SMTP发送电子邮件

该应用程序可以正常运行，我正在尝试使用Confirmable with Devise，在我的Rails应用程序上它说电子邮件已发送，但我从未收到它。 我正在通过SMTP配置Gmail。

谢谢。

ENV / production.rb

 config.action_mailer.default_url_options = { :host => 'https://my-task- tracker.herokuapp.com' } config.action_mailer.delivery_method = :smtp config.action_mailer.perform_deliveries = true config.action_mailer.raise_delivery_errors = false config.action_mailer.default :charset => "utf-8" config.action_mailer.smtp_settings = { :address => "smtp.gmail.com", :port => 587, :user_name => ENV["GMAIL_USERNAME"], :password => ENV["GMAIL_PASSWORD"], :authentication => "plain", :enable_starttls_auto => true } 

Answer 1

当您想通过Gmail smtp发送电子邮件时，您必须检查两件重要事项：

1. 您的应用配置：

   • 主持人： smtp.gmail.com
   • 端口： 587或465 （tls为587，ssl为465）
   • 协议： tls或ssl
   • 用户： [e-mail]
   • 密码： YOUR_PASSWORD

2. 给定的Gmail帐户设置：

   • 如果您为帐户启用了两步validation，则可能需要输入应用密码 。
   • 没有两步validation：
     1. 允许不太安全的应用访问您的帐户。
     2. 访问http://www.google.com/accounts/DisplayUnlockCaptcha并使用您的Gmail用户名和密码登录。

Answer 2

我遇到了类似的问题。 我遇到的问题是我没有告诉Heroku将我的配置变量复制到Heroku作为环境变量。 我在输入此命令后使用了figaro gem和smtp电子邮件：

 figaro heroku:set -e production 

我建议您确保使用正确的Gmail用户名和密码。

有关更多信息，请查看本教程。 我可以确认它有效http://usingname.space/2015/07/25/gmail-smtp-ruby-on-rails-actionmailer-and-you/

Answer 3

首先，heroku不允许免费发送邮件，您需要设置信用卡详细信息以发送邮件，其次

检查您是否正确配置

打开development.rb并使用以下内容进行更新

 config.action_mailer.delivery_method = :smtp config.action_mailer.default_url_options = { host:'localhost', port: '3000' } config.action_mailer.perform_deliveries = true config.action_mailer.raise_delivery_errors = true config.action_mailer.default :charset => "utf-8" config.action_mailer.smtp_settings = { :address => "smtp.gmail.com", :port => 25, :domain => 'localhost:3000', :user_name => "email id", :password => "password", :authentication => :plain, :enable_starttls_auto => true }
