如何在rails 3.0.3中设置邮件拦截器？

Question

我正在使用 Rails 3.0.3、ruby 1.9.2-p180、邮件（2.2.13）。我正在尝试设置邮件拦截器，但收到以下错误

 /home/abhimanyu/Aptana_Studio_3_Workspace/delivery_health_dashboard_03/config/initializers/mailer_config.rb:16:in `<top (required)>': uninitialized constant DevelopmentMailInterceptor (NameError)

如何修复它？

我正在使用的代码如下所示：

config/initializer/mailer_config.rb

ActionMailer::Base.default_charset = "utf-8"
ActionMailer::Base.default_content_type = "text/html"
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:enable_starttls_auto => true,
:address => "secure.emailsrvr.com",
:port => '25',
:domain => "domain",
:user_name => "user_name",
:password => "password",
:authentication => :plain

}

ActionMailer::Base.register_interceptor(DevelopmentMailInterceptor) if  Rails.env.development?

lib/development_mail_interceptor.rb

class DevelopmentMailInterceptor

  def self.delivering_email(message)
    message.to = "email"
  end

end

提前致谢。

Answer 1

require 'development_mail_interceptor' #add this line
ActionMailer::Base.register_interceptor(DevelopmentMailInterceptor) if  Rails.env.development?

Answer 2

我发现安装 mailcatcher gem 更容易。然后在development.rb中：

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :address              => "`localhost`",
    :port                 => 1025
  }

然后运行“mailcatcher”并在浏览器中点击http://localhost:1080/。它在后台运行，但可以直接从浏览器退出。为您提供文本+html 视图、源代码和分形分析（如果您这样做的话）。超级干净。
