API JSON从bash中获取ID

想知道是否有人能够帮助我从CURL命令输出的第一条记录中获得“SNAPSHOTID”，该记录输出下面的内容？我已经尝试过JQ但是我得到了API JSON从bash中获取ID

"parse error: Invalid numeric literal at line 1, column 6"

还有其他想法吗？

去'jq'，如果你没有它尝试'grep -oP'SNAPSHOTID“：”\ K [^“] +'input.json' –

请提供有关所提供答案的反馈并标记为已解决它解决了您的问题 – Inian

您能否让知道该解决方案是否有效？ – Inian

也许有点过于复杂，但工程：

grep SNAPSHOTID | head -n 1 | sed "s/[^\"']*.SNAPSHOTID.[^\"']*.\([^\"']*\).*/\1/"

如果包裹 'SNAPSHOTID' 到一个数组，然后您可以提取像这样

curl --silent http://url.to.json | jq '[.[].SNAPSHOTID] | .[0]'

的 - 无声开关取自man curl

-s, --silent Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.

我会去to_entries，然后生成一个数组，可以直接将需要指数，这部分，例如：

<test.json jq 'to_entries | first | .value.SNAPSHOTID'

输出：

"98758e4afc31f3"
