我刚刚使用 heroku ( http://fast-reaches-9399.herokuapp.com/ ) 启动了我的 rails 应用程序。我希望人们能够在顶部的文本区域中输入内容，然后单击提交按钮，然后将文本区域中的内容通过电子邮件发送给我。不过，我真的遇到了麻烦。它在开发环境中重定向，但似乎没有发送电子邮件。我在生产中收到 500 错误。这是一些相关的代码...

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery

  def email
    UserMailer.idea_bar(params[:message]).deliver
    redirect_to "/"  # how can I redirect to the page the user was just on?
  end
end

/mailers/user_mailer.rb

class UserMailer < ActionMailer::Base
  default from: "anonymous@collegeanswers.com", to: "info@collegeanswerz.com", subject: "collegeanswers"

  def idea_bar(message)
    mail(:body => message)
  end
end

application.html.erb（布局文件）

<div class="idea_bar">
    <div class="left_idea_bar">
        <p>Ideas, comments, questions, suggestions?  Help us help you!</p>
        <%= form_tag("/application_controller/email", :method => "post", :id => "idea_bar_form") do %>
          <%= text_area_tag('message', nil, :size => "60x4", :id => "message", :name => "message") %> <br />
          <%= label_tag(:email, "• include your email if you want a response:") %>
          <%= text_field_tag(:email, nil, :id => "email", :size => "36") %>
    </div>
          <button id="submit" type="submit" form="idea_bar_form"><span id="big_submit">Send</span>
          <span id="small_submit"><br />&#8226 one click<br />&#8226 anonymous</span></button>
        <% end %>
</div>

/user_mailer/idea_bar.html.erb （测试文件。我希望电子邮件是文本区域中的内容，而不是这个）

<html>
    <head></head>
    <body>
        <p>hello</p>
    </body>
</html>

/user_mailer/idea_bar.text.erb

hello

您可能会看到连接被拒绝错误，因为不允许您连接到 Heroku 上的本地 SMTP 服务器，这是不允许的。

您需要使用外部 SMTP 服务。Heroku 为多个提供外部 SMTP 服务的提供商提供插件，这些服务在其插件页面上列出：( https://addons.heroku.com/#email-sms )。每个附加组件都提供有关如何配置应用程序的说明

您还可以使用您拥有帐户的标准邮件服务，并通过 ActionMailer 对其进行配置。如果您有 GMail 帐户，您可以在 config/environments/production.rb 中尝试类似的操作。

从提供的日志中可以清楚地看出，您收到错误是因为 Rails ActionMailer 无法连接到 SMTP 服务器。要在生产中调试此问题，您可以将配置更改development.rb为：

config.action_mailer.raise_delivery_errors = true

所以你会在开发中看到邮件程序异常。当您有确切的错误消息时，您可以更新有问题的日志以获得进一步的帮助。
