无法使用 Sendgrid 接收电子邮件

【问题标题】：Not Able to Receive Email with Sendgrid无法使用 Sendgrid 接收电子邮件
【发布时间】：2014-12-09 17:32:10
【问题描述】：

我是学习 Ruby 的新手，目前正在学习构建我们的第一个应用程序的课程。我正在尝试设置一个用户帐户，用户在注册帐户时会收到一封确认电子邮件，但没有发送任何电子邮件。我设置了 SendGrid 并在 config/environments/development.rb 中设置了以下内容：

config.action_mailer.raise_delivery_errors = true

然后我检查了我的控制台以查看电子邮件是如何传递的。这是我收到的输出：

【问题讨论】：

  • 很高兴听到您正在学习 rails :)。您能否更新您的问题以包含您的 config/environments/development.rb 文件？请务必删除您的用户名和密码。
  • 从日志看来，邮件已发送 - 您是否检查了请求是否已到达发送网格？也许它是在您的垃圾邮件文件夹中收到的？
  • 你能评论一下实际的问题是什么吗？ :)

标签： ruby email authentication sendgrid


【解决方案1】：

您拥有实现此here 的基本文档。电子邮件似乎已发送，因此我建议您检查两件事：

  • 使用您的用户名/密码登录 sendgrid 并检查电子邮件是否已发送等。如果电子邮件已发送，则问题出在接收方（垃圾邮件等）
  • 检查您的配置（即config/environment.rb），因为您需要与下面的配置类似。

配置：

ActionMailer::Base.smtp_settings = {
  :user_name => 'your_sendgrid_username',
  :password => 'your_sendgrid_password',
  :domain => 'yourdomain.com',
  :address => 'smtp.sendgrid.net',
  :port => 587,
  :authentication => :plain,
  :enable_starttls_auto => true
}

【讨论】：

  • 嗨！我有你上面在初始化程序/setup_mail.rb:if Rails.env.development? ActionMailer::Base.delivery_method = :smtp ActionMailer::Base.smtp_settings = { address: 'smtp.sendgrid.net', port: '587', authentication: :plain, user_name: ENV['SENDGRID_USERNAME'], password: ENV['SENDGRID_PASSWORD'], domain: 'heroku.com', enable_starttls_auto: true } end 中描述的内容
  • 好的，看起来是正确的。您是否在您的环境中设置了 ENV 变量？也就是说，如果你输入控制台env | grep SENDGRID，你能在那里看到你的数据还是在你的rails应用程序中初始化？
  • 嘿！所以我尝试了env | grep SENDGRID，但它没有带来任何东西。然而heroku config:get SENDGRID_USERNAME heroku config:get SENDGRID_PASSWORD 和heroku addons 显示它已安装。
