訂正

記事内でgoogle books api使ったけど誤情報orデータがないが多すぎるから国会図書館とかのほうがいいかも

事前準備

pythonの環境設定
NotionのAPIキーの取得
対象ページにintegrationsを招待
対象ページのidをメモ

Notionのテーブル?設定

こんな感じでTitle, Author, PublishedDate, ISBNを定義する．
それぞれプロパティはtitle, text,text,numberにした．

流れ

ISBN(13桁) --> google books api --> Notion API

google books apiからはタイトル，著者名，出版日，ISBNを取得
Notion APIでPOSTする

使い方

python bookpost.py <13桁のISBN>

コード

プロパティの種類で書き方が違うことに注意．
textはrich_textって書く．
data=json.dumps(data)のとこを癖で日本語のエスケープ書くとpostでエラーになる．
