# 使用 Python AWS SDK 取得一批 Secrets Manager 秘密值
<a name="retrieving-secrets-python-batch"></a>

下列程式碼範例示範如何取得 Secrets Manager 秘密值的批次。

**必要許可：**
+ `secretsmanager:BatchGetSecretValue` 
+ `secretsmanager:GetSecretValue` 您要擷取之每個秘密的 許可。
+ 如果您使用過濾器，則還必須擁有 `secretsmanager:ListSecrets`。

如需許可政策範例，請參閱 [範例：擷取批次中一組秘密值的許可](auth-and-access_iam-policies.md#auth-and-access_examples_batch)。

**重要**  
如果您的 VPCE 原則拒絕擷取您要擷取之群組中個別密碼的權限，則 `BatchGetSecretValue` 不會傳回任何秘密值，而且會傳回錯誤。

```

    def __init__(self, secretsmanager_client):
