GetJobOutput与 S Amazon DK 或命令行工具配合使用

以下命令将文件库清单任务的输出保存到名为 output.json 的当前目录中的某个文件中：

aws glacier get-job-output --account-id - --vault-name my-vault --job-id zbxcm3Z_3z5UkoroF7SuZKrxgGoDc3RloGduS7Eg-RO47Yc6FxsdGBgf_Q2DK5Ejh18CnTS5XW4_XqlNHS61dsO4CnMW output.json

可在 aws glacier list-jobs 输出中找到 job-id。请注意，输出文件名是一个位置参数，不以选项名称作为前缀。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。

输出：

{
    "status": 200,
    "acceptRanges": "bytes",
    "contentType": "application/json"
}

output.json:

{"VaultARN":"arn:aws:glacier:us-west-2:0123456789012:vaults/my-vault","InventoryDate":"2015-04-07T00:26:18Z","ArchiveList":[{"ArchiveId":"kKB7ymWJVpPSwhGP6ycSOAekp9ZYe_--zM_mw6k76ZFGEIWQX-ybtRDvc2VkPSDtfKmQrj0IRQLSGsNuDp-AJVlu2ccmDSyDUmZwKbwbpAdGATGDiB3hHO0bjbGehXTcApVud_wyDw","ArchiveDescription":"multipart upload test","CreationDate":"2015-04-06T22:24:34Z","Size":3145728,"SHA256TreeHash":"9628195fcdbcbbe76cdde932d4646fa7de5f219fb39823836d81f0cc0e18aa67"}]}

示例 1：下载计划在指定作业中检索的存档内容，并将这些内容存储到磁盘上的文件中。如果有校验和，则下载会为您验证校验和。如果需要，可以像这样从服务响应历史中获取校验和（假设这个 cmdlet 是最后一次运行）：。$AWSHistory.LastServiceResponse如果 cmdlet 不是最近运行的，请检查$AWSHistory.Commands集合以获取相关的服务响应。
