LINE BOT APIを利用して電車遅延情報を送信する
というのを書いたのですが、ちょっと改造しました。
以下をできるようにしようと思います。
・祝日は通知しなくてよくしたい
・localで実行しているがIPアドレスが変わる可能性があるので送信できなかったときはメール通知をしたい
祝日に関してはholiday_jpというgemを使って判別することにしました。

メール送信はGmailを利用しようと思います。以下が参考になりました。

で、改良版の電車遅延情報を送信するものは以下のとおりです。

これを以下のような感じでcron設定して月曜から金曜までの出勤前の6:50に動作するようにしました。
