jqを使用してネストされた要素を検索する

親要素が動的に変更される（"Oauth2"、"Oauth2c"）オブジェクトのJSONリスト（以下に1つのオブジェクトが提供されている）があるため、オブジェクトを指定せずにネストされたレベル要素の例： - "scopes"を取得する方法下のパス？

scopesサンプルデータのオブジェクトは式を介してjqアクセスできます。

.[].flows[].scopes

[]パスワイルドカードとして機能します。代わりに、オブジェクトのすべての部分を提供します。

サンプルデータを考えると、次のようになります。

$ jq '.[].flows[].scopes' file.json
{
  "https://www.googleapis.com/auth/youtube": "Manage your YouTube account",
  "https://www.googleapis.com/auth/youtube.channel-memberships.creator": "See a list of your current active channel members, their current level, and when they became a member",
  "https://www.googleapis.com/auth/youtube.force-ssl": "See, edit, and permanently delete your YouTube videos, ratings, comments and captions",
  "https://www.googleapis.com/auth/youtube.readonly": "View your YouTube account",
  "https://www.googleapis.com/auth/youtube.upload": "Manage your YouTube videos",
  "https://www.googleapis.com/auth/youtubepartner": "View and manage your assets and associated content on YouTube",
  "https://www.googleapis.com/auth/youtubepartner-channel-audit": "View private information of your YouTube channel relevant during the audit process with a YouTube partner"
}
{
  "https://www.googleapis.com/auth/youtube": "Manage your YouTube account",
  "https://www.googleapis.com/auth/youtube.channel-memberships.creator": "See a list of your current active channel members, their current level, and when they became a member",
  "https://www.googleapis.com/auth/youtube.force-ssl": "See, edit, and permanently delete your YouTube videos, ratings, comments and captions",
  "https://www.googleapis.com/auth/youtube.readonly": "View your YouTube account",
  "https://www.googleapis.com/auth/youtube.upload": "Manage your YouTube videos",
  "https://www.googleapis.com/auth/youtubepartner": "View and manage your assets and associated content on YouTube",
  "https://www.googleapis.com/auth/youtubepartner-channel-audit": "View private information of your YouTube channel relevant during the audit process with a YouTube partner"
}

また、使用することができます

jq '.. | select(.scopes?).scopes' file.json

これにより、上記のサンプル文書と同じ出力が提供されます。scopesその後、キーを含むすべての項目を検索し、そのキーの内容を抽出します。

jq以前のバージョンを使用する必要があります。

jq '.. | select(type == "object" and has("scopes")).scopes' file.json
