将 GetVaultNotifications 与 AWS SDK 或 CLI 配合使用

以下命令获取名为 my-vault 的文件库的通知配置的描述：

aws glacier get-vault-notifications --account-id - --vault-name my-vault

输出：

{
    "vaultNotificationConfig": {
        "Events": [
            "InventoryRetrievalCompleted",
            "ArchiveRetrievalCompleted"
        ],
        "SNSTopic": "arn:aws:sns:us-west-2:0123456789012:my-vault"
    }
}

如果没有为该文件库配置任何通知，则会返回错误。Amazon Glacier 在执行操作时需要一个账户 ID 参数，但您可以使用连字符来指定正在使用的账户。
