私は次のことを達成しようとしています:
自分のドメインに送信されたすべての電子メールの宛先、本文、件名、および ... の内容を解析して、そこからファックス オブジェクトを作成し、ファックスとして送信します。
これまでのところ、Sendgrid を指すように MX レコードをセットアップでき、Ngrok を使用して Sendgrid の Parse API から、ローカルホスト サーバーでコールバックを取得できました。次のステップは、生のオブジェクトを操作できるオブジェクトに変換することです。これにより、Thoughtbot のGriddler Gemにたどり着きました。
これまでにアプリをセットアップした方法は次のとおりです。
Sendgrid セットアップ: URL: https://8c00fab0.ngrok.io/email_processor | Spam Check と Send Raw の両方にチェックが入っている
前に述べたように、私はこれを受け取っているので、この部分は機能します:
