我正在 Heroku 上开发一个 Ruby on Rails 3.2 应用程序。我添加了 sendgrid 插件

heroku addons:add sendgrid:starter

然后重新启动

heroku restart

但是，如果我尝试在我的应用程序中发送密码电子邮件（我正在使用设计登录 gem），我会在日志中得到这个

您需要配置ActiveMailer类似的东西

ActionMailer::Base.smtp_settings = {
  :address        => "smtp.sendgrid.net",
  :port           => "25",
  :authentication => :plain,
  :user_name      => ENV['SENDGRID_USERNAME'],
  :password       => ENV['SENDGRID_PASSWORD'],
  :domain         => ENV['SENDGRID_DOMAIN']
}

并确保您的应用程序在环境中具有 SEGRID 配置变量 - 您可以使用heroku config.
