Ottieni un valore segreto di Secrets Manager usando l'SDK Python AWS

Nelle applicazioni, puoi recuperare i tuoi segreti chiamando GetSecretValue o BatchGetSecretValue in uno qualsiasi dei. AWS SDKs Tuttavia, ti consigliamo di memorizzare nella cache i valori del segreto utilizzando la caching lato client. Memorizzare i segreti nella cache migliora la velocità e riduce i costi.

Per le applicazioni Python, utilizza il componente di caching basato su Python di Secrets Manager o chiama direttamente l'SDK con get_secret_value o batch_get_secret_value.

Gli esempi di codice seguenti mostrano come utilizzare GetSecretValue.
