Question

我有一个来自HPE OneView的JSON输出。一个简短的例子是：

{
   "uri": "/rest/server-hardware/*/firmware?start=0&count=32",
   "total": 102,
   "start": 0,

           },
           {
               "componentVersion": "U34 v2.10 (05/21/2019)",
               "componentLocation": "System Board",

     }
   ],
   "modified": "2020-07-27T09:30:55.882Z",
   "nextPageUri": null
}

我知道我可以使用jq -r '.members[] | select(.serverModel == "Proliant DL380 Gen10") | .components[] | select(.componentName == "System ROM") |.componentVersion' firmware来检索DL380 Gen 10s的系统ROM版本，但是我还想将serverName和系统ROM版本一起打印。我正在尝试的所有操作都给出了错误。有人知道怎么做吗？

构建字符串是一个好技巧。如果有帮助，您还可以构建中间对象，以使事物以更易于理解的形式显示。例如

$ cat stuff.jq
.members[]
   | select(.serverModel == "Proliant DL380 Gen10")
   | {
       name: .serverName,
       rom: ( .components[] | select(.componentName == "System ROM") | .componentVersion )
       }
   | "The ROM version for \(.name) is \(.rom)"

这将提供以下输出：

$ jq -rf stuff.jq firmware.json 
The ROM version for bb-r2-n12-ilo is U30 v1.46 (10/02/2018)
The ROM version for bb-r5-n10-ilo is U30 v1.36 (02/15/2018)
$
