au moins vous aurez besoin du champ: https://www.googleapis.com/auth/drive.metadata.readonly + OAuth (API-Key & Client-ID)
vous pouvez le tester à: https://developers.google.com/drive/v3/reference/files/list
dans l'entrée "champs" ajouter: fichiers (iconLink, thumbnailLink)
si vous utilisez https://apis.google.com/js/api.js, assurez-vous d'ajouter votre domaine à API-Key -> HTTP-Référent & client-ID -> JavaScript Source & Forwarding-URI (@https://console.developers.google.com/apis/credentials)
vous pouvez trouver un échantillon d'utilisation GAPI de base ici: https://github.com/google/google-api-javascript-client/blob/51aa25bed4f6c36d8e76fd3b9f7e280ded945c98/samples/loadedDiscovery.html
Je promisified le client GAPI un peu il y a quelque temps, parce que je détestais le mélange des callbacks et thenables dans les méthodes .. cela a fonctionné pour moi (en supposant que api.js était déjà chargé), mais seulement contenir 100 entrées de fichiers dans la réponse.
