Geteilte Ablagen verwalten

Diese Anleitung enthält Aufgaben zum Verwalten geteilter Ablagen, z. B. zum Erstellen von geteilte Ablagen sowie Mitglieder und Berechtigungen verwalten.

Weitere Informationen zu den Beschränkungen für Ordner in geteilten Ablagen .

Geteilte Ablagen erstellen

Verwenden Sie zum Erstellen einer geteilten Ablage die Methode drives.create.

Hinweis: Wenn Sie mit der früheren Version der Drive API Version 2 arbeiten, verwenden Sie die Methode drives.insert-Methode. Sie finden Codebeispiele in GitHub.

Aufrufe der Methode drives.create sind idempotent.

Der Parameter requestId identifiziert den logischen Versuch, das gemeinsam genutzte Element zu erstellen. Google Drive. Wenn die Anfrage das Zeitlimit überschreitet oder einen unbestimmten Back-End-Fehler zurückgibt, kann wiederholt werden. Die requestId und der Text der Anfrage müssen unverändert bleiben.

Wenn die geteilte Ablage aufgrund einer vorherigen Anfrage oder aufgrund eines wiederholen, wird die normale Antwort zurückgegeben. Manchmal, z. B. nach einer längeren oder wenn sich der Anfragetext geändert hat, könnte der Fehler 409 zurückgegeben, das angibt, dass requestId verworfen werden muss.

Mitglieder einer geteilten Ablage hinzufügen oder entfernen

Sie können Mitglieder für geteilte Ablagen über das permissions-Ressource.

Wenn Sie ein Mitglied hinzufügen möchten, müssen Sie die Berechtigung für die geteilte Ablage erstellen. Berechtigung können auch für einzelne Dateien in einer geteilten Ablage verwendet werden, Mitgliedern zusätzliche Berechtigungen erteilen oder die Zusammenarbeit mit Nichtmitgliedern ermöglichen. bestimmte Elemente.

Weitere Informationen und Beispielcode finden Sie unter Dateien, Ordner und Google Drive.

Geteilte Ablagen löschen

Verwenden Sie die Methode drives.delete, um Folgendes zu löschen: geteilte Ablage. Alle Inhalte in der geteilten Ablage müssen in den Papierkorb verschoben oder gelöscht werden bevor Sie die geteilte Ablage löschen.

Geteilte Ablagen für Domainadministratoren verwalten

Wenden Sie den Parameter useDomainAdminAccess mit den Ressourcen drives und permissions an, um geteilte Ablagen in einem Unternehmen.

Nutzer, die diese Methoden mit useDomainAdminAccess=true aufrufen, müssen über die Drive and Docs Administrator privilegiert. Administratoren können nach freigegebenen Google Drive oder aktualisieren Sie die Berechtigungen für geteilte Ablagen, Laufwerke, die ihrer Organisation gehören, unabhängig von der Mitgliedschaft des Administrators in einer beliebigen geteilten Ablage.

Geteilte Ablagen ohne Organisator wiederherstellen

Das folgende Beispiel zeigt, wie Sie mit diesen Ressourcen freigegebene Elemente wiederherstellen für Fahrten ohne Organisator.

Beschränkungen für Ordner

Für Ordner in geteilten Ablagen gelten bestimmte Speicherlimits. Weitere Informationen finden Sie unter Freigegebene Laufwerklimits in Google Drive

Elementobergrenze

Jeder Ordner in der geteilten Ablage eines Nutzers ist auf 500.000 Elemente beschränkt, darunter Dateien, Ordner und Verknüpfungen.

Wenn das Limit erreicht ist, können in der geteilten Ablage keine Elemente mehr angenommen werden. Bis wieder Dateien empfangen, müssen die Nutzer die Elemente endgültig aus dem Ordner löschen. Hinweis Elemente im Papierkorb werden auf das Limit angerechnet, aber endgültig gelöscht. sollten Sie nicht. Weitere Informationen finden Sie unter Dateien in den Papierkorb verschieben oder löschen und Ordner.

Limit für die Ordnertiefe

Ein Ordner in einer geteilten Ablage darf nicht mehr als 100 Ebenen verschachtelter Ordner enthalten. Das bedeutet, dass ein untergeordneter Ordner nicht unter einem Ordner gespeichert werden kann, der mehr als 99 Ebenen. Diese Einschränkung gilt nur für untergeordnete Ordner.

Beim Versuch, mehr als 100 Ordnerebenen hinzuzufügen, wird ein teamDriveHierarchyTooDeep HTTP-Statuscodeantwort.

Hinweis: Im Feld drives gibt es kein Google Drive API, mit der die Tiefe eines Ordners zurückgegeben werden kann So ermitteln Sie den Ordner: müssen Sie die Ordnerhierarchie manuell aufsteigen.
