问题描述

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

I just launched my rails app with heroku (http://fast-reaches-9399.herokuapp.com/). I want people to be able to type stuff in the textarea on the top, and then click the submit button, and then have it email me what is in the textarea. I'm really having trouble with it though. It redirects in the development environment, but doesn't seem to send an email. And I get a 500 error in production. Here's some relevant code...

application_controller.rb

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

/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

应用.html.erb（布局文件）

application.html.erb (layout file)

<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textarea，不是这个）

/user_mailer/idea_bar.html.erb (test file. I want the email to be what's in the textarea, not this)

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

/user_mailer/idea_bar.text.erb

/user_mailer/idea_bar.text.erb

hello

推荐答案

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

You're likely seeing the connection refused error because you're not being allowed to connect to the local SMTP server on Heroku, which is not allowed.

您需要使用外部SMTP服务。 Heroku的插件页面上列出了一些提供外部SMTP服务的提供商的插件：（ https：// addons.heroku.com/#email-sms ）。每个插件都提供有关如何配置应用程序的说明

You'll need to use an external SMTP service. Heroku has plug-ins for several providers which offer external SMTP service listed on their addons page: (https://addons.heroku.com/#email-sms). Each add-on provides instructions on how to configure your application

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

You could also use a standard mail service for which you have an account and configure it through ActionMailer. You can try something like this in your config/environments/production.rb if you have a GMail account.
