GitHub API v3を使ってPull Requestの最終Push日時を取得する
こんにちは、CX事業本部の若槻です。
最近、Pull RequestのCloseの自動化のために、「最後にCommitがPushされた日時を取得」する処理を実装する必要がありました。
そこで今回は、GitHub API v3を使ってPull Requestの最終Push日時を取得する方法を確認してみました。
やってみた
アクセストークンの発行
まだの場合は下記から発行します。スコープはrepoのrepo:statusを指定します。
Pull Requestの最終Push日時を取得する
まずPull Requestの情報を取得します。GitHub API v3の下記のエンドポイントを使用すれば取得可能です。
GET /repos/{owner}/{repo}/pulls/{pull_number}
GITHUB_ACCESS_AOKENには先ほどのアクセストークンを指定します。octocat/hello-worldはGitHubが公開しているRepositoryです。このRepositoryの番号997のPull Requestを取得してみます。
% GITHUB_ACCESS_AOKEN=##GITHUB_ACCESS_AOKEN##
% result=$(curl \
-H "Accept: application/vnd.github.v3+json" \
-H "Authorization: token ${GITHUB_ACCESS_AOKEN}" \
https://api.github.com/repos/octocat/hello-world/pulls/997)
するとPull Requestの情報がJSONで出力されます。（長いため折りたたんでいます。）

このうちPull Requestの最終Push日時は.head.repo.pushed_atの値となります。
% echo ${result} | jq -r .head.repo.pushed_at
2021-07-08T01:18:14Z
これでPull Requestの最終Push日時が取得できました。
別解
以前、前述のエンドポイントのバグ？で.head.repoに同Pull Requestの.base.repoと同じ値がなぜか入ってきて、うまく最終Push日時が取得できない時がありました。
その時には別解として以下のエンドポイントを代替で利用していました。
GET /repos/{owner}/{repo}/events
このエンドポイントを使用すると指定のRepositoryで発生したEventが取得できます。EventのType一覧は下記で確認できます。
しかしこのエンドポイントはRepository内の全てのEventが取得できてしまうため、その結果から指定のPull RequestのPushEventを下記のようなループ処理を実装するなどしてフィルターする必要があります。
page=1
pushed_at=$null
while [ -z "$pushed_at" ] && [ $page -le 5 ]; do
echo "page="$page
pushed_at=$(curl -sS -H "$ACCEPT_HEADER" -H "$AUTH_HEADER" "${GH_API_HOST}/events?per_page=100&page=${page}" | \
jq --arg ref $pull_branch_ref '.[] | select(.payload.ref == $ref and .type == "PushEvent")' | \
jq -rs '.[0].created_at' \
)
page=$((page+1))
done
しかし最初のGET /repos/{owner}/{repo}/pulls/{pull_number}が正常に使えるようになったため、上記の冗長な方法を取らずに済んで良かったです。
以上
