我已经集成了 Sendgrid 传入解析 Webhook API，它正确地将电子邮件对象发布到我的 rails 应用程序。在应用程序上，我使用 griddler gem 来捕获并进一步处理电子邮件数据。但我得到以下异常：

Sent mail to chandan@exmaple.com (77.6ms)

我在 /mailer/email_processor.rb 中有流程实例方法

class EmailProcessor
  def initialize(email)
    @email = email
    puts "initialized Email Processor\n\n\n\n\n\n\n\n" # Should see this line in log
  end

  def process
    user = User.find_by_email(@email.from[:email])
    puts @email.inspect and return if user.blank?

    puts "############### @email = #{@email.inspect}###############\n\n\n\n\n\n\n"
  end
end

这是 config/initializer/griddler.rb

Griddler.configure do |config|
  config.processor_class = EmailProcessor
  config.processor_method = :process
  config.reply_delimiter = '-- REPLY ABOVE THIS LINE --'
  config.email_service = :sendgrid
end

这是我正在使用的 gem 版本：

#Process incoming mail from sendgrid smtp server
gem 'griddler', "~> 1.1.0"
gem 'griddler-sendgrid', "~> 0.0.1"

这是基于griddler github上提供的文档

谁能帮我解决我在这里缺少的东西。另外，为什么我在日志中看不到以下行？

"initialized Email Processor\n\n\n\n\n\n\n\n"

以下是定义路线的行

mount_griddler

编辑：据我所知，rails 不会直接添加任何此类。奇怪的是，我能够在'rails console'中看到'EmailProcessor'类可用的'process'方法：

2.1.4 :005 > x = EmailProcessor.new(1)
initialized Email Processor\n\n\n\n\n\n\n\n
 => #<EmailProcessor:0x007fc6ae5aee08 @email=1>
2.1.4 :006 > x.methods
 => [:process, :blank?, :present?, ...
2.1.4 :014 > EmailProcessor.instance_methods(false)
 => [:process]

谢谢

问题是，EmailProcessor该类没有加载 Rails 应用程序启动。添加以下几行来application.rb做到这一点：

 config.autoload_paths += %W(#{config.root}/app/mailers/email_processor.rb)

注意：每次对 email_processor.rb 进行更改时，都需要重新启动服务器。

感谢 Joel Oliveira（Griddler的作者）回复我的个人电子邮件并指出问题 :)
