/*
Notes-en:
- Adds a new article for your WordPress.com account. (Unpublished state)
    - WordPress.com is a service that hosts WordPress sites. It is provided by Automattic itself.
- If in HTML code, it will be generated in "Block editor" mode.
    - If in plain text, it will be generated in "Classic editor" mode.
- If the datetime are set in date format, considered as "00:00".
    - eg: "2021-12-31" to "2021-12-31 00:00"
    - If publish for a future date, it will be posted as a schedule.
- "URL" is not always a published URL.
    - Anyone who can log in to the WordPress.com site can access it even before it is published.
    - `permalink_URL` will be confirmed when it is published.

APPENDIX-en
- Line breaks in Title and Excerpt are not available. (Template compatibility)
    - If necessary, manually start a new line when posting.
    - To enable line breaks, set TEXTAREA and modify the BR conversion code
- For the ID of the existing article, refer to the URL of the edit screen.
    - Number following `post =`
- Will be added as an article of "default language" in the case of WPML plugin (multilingual site).
    - There is no way to add it as an article in a translation language.
- You can also refer to it by "Site ID" (blogid) instead of the WordPress.Com domain.
    - Site ID (blogid) is obtained from `GET v1.1/sites/example.blog/` and the "View page source".
- Request is made to the "WordPress.com REST API" (WP.COM API).
    - https://developer.wordpress.com/docs/api/
    - Note: Not the "WP.REST API" for WordPress.Org.
- Setting example of "HTTP Authentication" (OAuth2)
    - Authorization Endpoint URL:
        - https://public-api.wordpress.com/oauth2/authorize
    - Token Endpoint URL:
        - https://public-api.wordpress.com/oauth2/token
    - Scope:
        - "global", "", "auth" or "media"
        - (document) https://developer.wordpress.com/docs/oauth2/
        - By default, the token will grant the application full access to a single blog.
        - Needs a "global" scope, if to access to all the blogs that users have on WordPress.com.
    - Client ID, Consumer Secret:
        - ( from https://developer.wordpress.com/apps/ )
        - Redirect URLs: https://s.questetra.net/oauth2callback

Notes-ja:
- WordPress.com アカウントの記事を新規追加します。（未公開状態）
    - WordPress.com は WordPress sites をホストするサービスです。Automattic 社自身が提供しています。
- 原稿が HTML で書かれている場合、"Block editor" モードで生成されます。
    - 原稿が Plain テキストで書かれている場合、"Classic editor" モードで生成されます。
- 日時が日付フォーマットで設定された場合、"00:00" とみなされます。
    - 例: "2021-12-31" → "2021-12-31 00:00"
    - 未来日付がセットされている場合に公開操作を行うと "スケジュール投稿" になります。
- "記事URL" は公開URLとは限りません。
    - WordPress.com サイトにログインできるユーザであれば公開前でもアクセス可能です。
    - `permalink_URL` は公開された時点で確定します。

APPENDIX-ja:
- TitleとExcerptの改行は不可の仕様となっています。（テンプレート互換性等に配慮）
    - 必要あれば、公開作業の際に手動で改行してください。
    - 仕様として改行可としたい場合は TEXTAREA 設定とBR変換のコード改変が必要です。
- 既存記事のIDは、編集画面のURL等を参照してください。
    - `post=` に続く数字
- WPMLプラグイン環境（多言語サイト）の場合、"デフォルト言語" の記事として追加されます。
    - 翻訳言語の記事として追加する方法はありません。
- WordPress.Com ドメインの代わりに「サイトID」（blogid）で参照することも可能です。
    - サイトID（blogid）は、"`GET v1.1/sites/example.blog/`" や "ページのソース" 等から取得します。
- "WordPress.com REST API" (WP.COM API) に対してリクエストが投げられます。
    - https://developer.wordpress.com/docs/api/
    - 注： WordPress.Org 用の "WP.REST API" ではありません。
- "HTTP認証設定" の例 (OAuth2)
    - 認可エンドポイント URL:
        - https://public-api.wordpress.com/oauth2/authorize
    - トークンエンドポイント URL:
        - https://public-api.wordpress.com/oauth2/token
    - スコープ:
        - "global", "", "auth" or "media"
        - (document) https://developer.wordpress.com/docs/oauth2/
        - デフォルトでは、１つの blog に対するアクセスが認可されます。
        - 全保有 blogs へアクセスできるようにするには "global" をセットします。
    - クライアントID, クライアントシークレット:
        - ( 開発者ページから取得してください⇒ https://developer.wordpress.com/apps/ )
        - Redirect URLs: https://s.questetra.net/oauth2callback
