如何在Rails中通过HTTParty使用邮件枪

gem 'httparty'

require 'httparty'

class EmailSender
  include HTTParty

  def self.send_email(to, subject, body)
    base_uri 'https://api.mailgun.net/v3'
    basic_auth 'api', 'YOUR_MAILGUN_API_KEY'
    headers 'Content-Type' => 'application/x-www-form-urlencoded'

    post('/YOUR_DOMAIN_NAME/messages', body: {
      from: 'YOUR_EMAIL_ADDRESS',
      to: to,
      subject: subject,
      text: body
    })
  end
end

class EmailsController < ApplicationController
  def send_email
    to = 'recipient@example.com'
    subject = 'Hello'
    body = 'This is the email body.'

    EmailSender.send_email(to, subject, body)

    render plain: 'Email sent successfully!'
  end
end
