使用第三方库通过http发送电子邮件时，我可以使用ActionMailer吗？

Question

I am using a 3rd party library that sends emails using a HTTP based API.

Is it still possible for me to use ActionMailer to construct the emails and then somehow use ActionMailer to generate the resulting HTML/text for the email which I could then pass to my http email lib to send?

Answer 1

Absolutely. In fact, this is standard practice. You don't need to do anything special, just configure ActionMailer to use the 3rd party of your choice. Here's an example from my production.rb file, using Mailgun:

Rails.application.configure do
  # other config stuff goes here...

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.default_url_options = { host: 'your_domain.com' }
  config.action_mailer.smtp_settings = {
    authentication: :plain,
    address: 'smtp.mailgun.org',
    port: 587,
    domain: Rails.application.secrets[:mailgun_domain],
    user_name: Rails.application.secrets[:mailgun_username],
    password: Rails.application.secrets[:mailgun_password]
  }
end

Then in your Rails.application.secrets file, you put the info specific to your account.
