Gestisci Drive condivisi

Questa guida contiene attività relative alla gestione dei Drive condivisi, come la creazione di Drive condivisi e la gestione di membri e autorizzazioni.

Creare Drive condivisi

Le chiamate al metodo drives.create sono idempotenti.

Il parametro requestId identifica il tentativo logico di creare il Drive condiviso. Se la richiesta scade o restituisce un errore di backend indeterminato, la stessa richiesta può essere ripetuta. Il requestId e il corpo della richiesta devono rimanere invariati.

Se il Drive condiviso è stato creato correttamente in seguito a una richiesta precedente o in seguito a un nuovo tentativo, viene restituita la risposta normale. A volte, ad esempio dopo un tempo prolungato o se il corpo della richiesta è cambiato, potrebbe essere restituito un errore 409 che indica che requestId deve essere eliminato.

Aggiungere o rimuovere membri di un Drive condiviso

Aggiungere o rimuovere membri del Drive condiviso utilizzando la risorsa permissions.

Per aggiungere un membro, crea l'autorizzazione sul Drive condiviso. Puoi utilizzare metodi di autorizzazione anche su singoli file all'interno di un Drive condiviso per concedere ai membri ulteriori privilegi o consentire ai non membri di collaborare su elementi specifici.

Per ulteriori informazioni e il codice di esempio, vedi Condividere file, cartelle e Drive.

Eliminare un Drive condiviso

Utilizza il metodo drives.delete per eliminare un Drive condiviso. Tutti i contenuti del Drive condiviso devono essere spostati nel cestino o eliminati prima di eliminare il Drive condiviso.

Gestire i Drive condivisi per gli amministratori di dominio

Applica il parametro useDomainAdminAccess con le risorse drives e permissions per gestire i Drive condivisi in un'organizzazione.

Gli utenti che chiamano questi metodi con useDomainAdminAccess=true devono disporre del privilegio di amministratore Drive and Docs. Gli amministratori possono cercare i Drive condivisi o aggiornare le autorizzazioni per i Drive condivisi di proprietà dell'organizzazione, indipendentemente dalla loro appartenenza ai Drive condivisi.

Ripristinare un Drive condiviso senza organizzatore

L'esempio seguente mostra come utilizzare queste risorse per recuperare i Drive condivisi che non hanno più un organizzatore.
