使用 Python Amazon SDK 获取 Secrets Manager 密钥值

在应用程序中，您可以通过调用GetSecretValue或BatchGetSecretValue在任一应用程序中检索您的秘密 Amazon SDKs。不过，我们建议您通过使用客户端缓存来缓存您的密钥值。缓存密钥可以提高速度并降低成本。

对于 Python 应用程序，请使用 Secrets Manager 基于 Python 的缓存组件或直接使用 get_secret_value 或 batch_get_secret_value 调用 SDK。

以下代码示例演示如何使用 GetSecretValue。

所需权限：secretsmanager:GetSecretValue
