ruby-on-rails - Ruby Mailer提出了EOFError

我在 Controller 中的此代码上收到EOFError(文件结束错误)。该错误出现的块是在UserMailer.deliver_message(的行的末尾，我不知道如何解决此问题，我被困了大约2个月，建议您使用此站点。请帮忙。

  def contact
      @title= "Contact Us"
      if request.post?
       @message= Message.new(params[:contact])
        if @message.valid?
           UserMailer.deliver_message(
            :message => @message
            )
          flash[:notice] = "Thank you for contacting us"
          redirect_to contact_url
         end
        end
      end

这是消息文件:

<%= @message.name %> has sent feedback or a question:

  Message: <%= @message.body %>

  From: <%= @message.email %>

这是UserMailer

class UserMailer < ActionMailer::Base

  def message(mail)
    subject    'Feedback/Questions'
    recipients 'Email@email'
    from       'webmaster'
    body        mail
  end
end

好了，这是我得到的错误

PedalsController＃contact中的EOFError

到达文件末尾

这是应用程序跟踪

也许我缺少真正愚蠢的东西，但是如果有人可以回答这个问题，那将是惊人的。另外，我的解决办法是什么？

最佳答案

如果SMTP服务器关闭，也会发生这种情况。 (我使用了一个名为Sendgrid的第三方邮件，这种情况在它完全崩溃时发生了一次)
