GitHub APIでコミット履歴を取得する

概要

GitHub APIを利用して、コミット履歴を取得します。

publicリポジトリのコミット履歴を取得するので、認証についての考慮はしません。

利用するAPI

https://api.github.com/repos/{owner}/{repo}/commits
を利用します。（詳細は下記）
https://docs.github.com/en/github-ae@latest/rest/reference/repos#list-commits

　やってみた

試しにこのリポジトリの2020年のコミットを1つ取得するために、下記のようなリクエストを投げてみました。

https://api.github.com/repos/nannany/reading_memo/commits?since=2018-01-01T00:00:00+0900&until=2018-12-31T23:59:59+0900&per_page=1

結果はこんな感じ。

感想

GitHub APIには多くのエンドポイントが用意されており驚きました。
(OPEN API Specのファイルが６０,０００行弱ありました😲)
