L'URL della richiesta può essere relativo all'URL di base. La versione dell'API del servizio usata per la richiesta è uguale a quella del client, se non diversamente specificato. L'override della versione dell'API configurata del client nell'URL relativo è supportata nel client con l'API versione 2022-08-31 e successive. Override dell'URL assoluto supportato nel client con qualsiasi versione dell'API. Questo metodo non genera se la risposta è un errore; per generare un'eccezione, chiamare raise_for_status() sull'oggetto risposta restituito.
