Question

我正在尝试从下面的JSON文件中获取密钥：

我刚刚执行了以下命令，它将给出以下JSON输出

命令：

jq -r '.issues'

输出：

"issues": [
    {
      "expand": "operations,versionedRepresentations,editmeta,changelog,renderedFields",
      "id": "1999875",
      "self": "https://amazon.kindle.com/jira/rest/api/2/issue/1999875",
      "key": "KINDLEAMZ-67578"
    },
    {
      "expand": "operations,versionedRepresentations,editmeta,changelog,renderedFields",
      "id": "2019428",
      "self": "https://amazon.kindle.com/jira/rest/api/2/issue/2019428",
      "key": "KINDLEAMZ-68661"
    },
    {
      "expand": "operations,versionedRepresentations,editmeta,changelog,renderedFields",
      "id": "2010958",
      "self": "https://amazon.kindle.com/jira/rest/api/2/issue/2010958",
      "key": "KINDLEAMZ-68167"
    }
  ]
}

我只想获取以下格式的输出，不确定如何获取。

预期输出：

{
"JIRA-1":"KINDLEAMZ-67578",

"JIRA-2":"KINDLEAMZ-68661",

"JIRA-3":"KINDLEAMZ-68167"
}

如何从每个数组中获取键值并显示如上？并根据结果增加JIRA-n。

Answer 1

给定一个数组，您可以使用to_entries/1将该数组映射为索引和值的数组。然后，您可以使用reduce或with_entries/1映射到对象上想要的键和值。

reduce (.issues | to_entries[]) as {$key,$value} ({};
    .["JIRA-\($key + 1)"] = $value.key
)

.issues | with_entries({key: "JIRA-\(.key + 1)", value: .value.key})

https://jqplay.org/s/H2uxyFJn9E

似乎您使用的版本小于1.5。您需要进行一些调整并删除解构。

reduce (.issues | to_entries[]) as $e ({};
    .["JIRA-\($e.key + 1)"] = $e.value.key
)

无法在Shell脚本中使用jq获取JSON数组值
