Question

我正在尝试将Devise密码提醒电子邮件发送出去。单击提醒链接时，日志文件包含以下错误：

我认为我只是在设置配置时遇到语法问题。查看config/environments/production.rb：

Rails.application.configure do
  ...
  config.action_mailer.default_url_options = {host: 'wombatdb.com'}

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :address              => "wombatdb.com",
    :domain               => "wombatdb.com",
    :enable_starttls_auto => false,
    :openssl_verify_mode => OpenSSL::SSL::VERIFY_NONE
  }
  ...
end

rails主机也是邮件主机，他们有互联网域名＆＃39; wombatdb.com＆＃39;。如果我去生产rails控制台，我可以像这样读取配置：

rails@wombatdb:~/wombat$ bin/rails c production
Loading production environment (Rails 4.2.7.1)
irb(main):001:0> ActionMailer::Base.default_url_options
=> {:host=>"wombatdb.com"}

关于什么可能出错的任何想法？我重启了nginx＆amp;独角兽服务97次。

rails 4.2.7.1 ruby 2.3.0

一切似乎都是正确的，你确定你已经在生产模式下启动了应用程序吗？尝试在development.rb上使用相同的配置，然后再试一次，以解除该选项。

default_url_options的语法
