Importer un article depuis un flux RSS WordPress

Cette requête importe un article depuis un flux RSS WordPress, en utilisant le titre, le contenu et l'extrait de l'article.

Si l'auteur avec ce nom d'utilisateur existe localement, il l'utilise ; sinon, il le remplace par celui défini via la variable $defaultAuthorUsername.

La variable $url reçoit l'URL du flux RSS de l'article WordPress individuel. Il s'agit généralement de l'URL de l'article + "/feed/rss/?withoutcomments=1". Par exemple :

https://wordpress.com/blog/2024/07/16/wordpress-6-6/feed/rss/?withoutcomments=1

query GetPostFromRSSFeedAndExportData(
  $url: URL!
) {
  _sendHTTPRequest(input: {
