api - oauthでbash curlを使用して、Googleアプリのユーザーアカウントデータを返しますか?

Question

curl を使用して、Google Apps のユーザーアカウントのバッチに関する情報 (createddate や lastlogin など) を返すかなり簡単な方法を探しています。私は curl と Google Apps API の経験があまりありません。

Oauth で curl を使用してユーザーアカウントデータを要求する方法に関する優れた紹介記事を知っている人はいますか?

前もって感謝します！

OAuth 2.0 と JSON は Bash では簡単に処理できないため、これは簡単には達成できません。そうは言っても、探しているデータを提供する基本的なバージョンは次のとおりです。grep はいくつかのクリーンアップを使用できますが、繰り返しになりますが、JSON を grep で解釈することは、いずれにせよ本当に悪い考えです。これは、 Google API ライブラリが存在し、使用する必要がある理由の完璧な例です。

Jay Lee さん、ありがとうございます。通常のユーザー情報 (Google アプリではありません) にアクセスするための修正したスクリプトを共有したいと思います。Google API コンソールで Google+ API をオンにすることを忘れないでください。
