# 使用 Go AWS 開發套件取得 Secrets Manager 秘密值
<a name="retrieving-secrets-go-sdk"></a>

在應用程式中，您可以透過在任何 AWS SDKs `BatchGetSecretValue`中呼叫 `GetSecretValue`或 來擷取秘密。不過，建議您使用用戶端快取來快取您的秘密值。快取秘密可提高速度並降低成本。

對於 Go 應用程式，請使用 [Secrets Manager Go 型快取元件](retrieving-secrets_cache-go.md)或使用 [https://docs.aws.amazon.com/sdk-for-go/api/service/secretsmanager/#SecretsManager.GetSecretValue](https://docs.aws.amazon.com/sdk-for-go/api/service/secretsmanager/#SecretsManager.GetSecretValue) 或 [https://docs.aws.amazon.com/sdk-for-go/api/service/secretsmanager/#SecretsManager.BatchGetSecretValue](https://docs.aws.amazon.com/sdk-for-go/api/service/secretsmanager/#SecretsManager.BatchGetSecretValue) 直接呼叫 SDK。

下列程式碼範例顯示如何取得 Secrets Manager 秘密值。

**必要許可：**`secretsmanager:GetSecretValue`
