如何创建自定义电子邮件标题 [英] How to create custom email headers

问题描述

我正在尝试创建自定义电子邮件标头以使用 SendGrid api.

I'm trying to create a custom email header to use the SendGrid api.

这是我正在做的 - 但它不起作用:

Here's what I'm doing - but its not working:

class Mailman < ActionMailer::Base
  default :from => "[e-mail]"

  def send_message(name, email, message)
    @name = name
    @email = email
    @message = message

    mail(:to => '[e-mail]',
     :from => email,
     :subject => "Message from the site",
     :headers['X-SMTPAPI'] => "category: Drip Email"
    )
  end

end

感谢任何帮助.

谢谢，亚当

推荐答案

你可以使用 ActionMailer 的 #headers 方法，我已经编辑了你的例子来展示如何:

You can use the #headers method of ActionMailer, I've edited your example to show how:

class Mailman < ActionMailer::Base
  default :from => "[e-mail]"

  def send_message(name, email, message)
    @name = name
    @email = email
    @message = message

    headers['X-SMTPAPI'] = '{"category": "Drip Email"}'

    mail(
     :to => '[e-mail]',
     :from => email,
     :subject => "Message from the site"
    )
  end

end

或者，您也可以将散列作为参数传递(传递给方法 #headers):

Alternatively, you can pass a hash as an argument (to the method #headers) too:

headers {"SPECIFIC-HEADER-1" => "value", "ANOTHER-HEADER" => "and so..."}

我希望这可以帮助您，如果不能，您可以随时查看 Rails 指南:http:///edgeguides.rubyonrails.org/action_mailer_basics.html.

I hope this can help you, and if not you always can check the rails guides: http://edgeguides.rubyonrails.org/action_mailer_basics.html.
