到目前为止，我尝试了这个对我来说部分有效。
.data.assets[] |选择 (.tags[].value=="sourcing") | . += "domain":"sourcing"
问题是我希望这个条件适用于数组中的每个对象，但我无法做到这一点。它仅应用于第一个对象。
我哪里做错了？请问有什么建议吗？
【问题讨论】：
你需要在.data.assets[]中指定位置。
给定的输出和规定的目标不匹配。 "domain": "supply-chain"哪里来的？？？
【参考方案1】：
以下似乎符合描述性要求：
.data.assets |=
map( if any(.tags[].value; . == "sourcing")
then . + "domain":"sourcing"
else .
end )
这会产生所需的输出，但键值对 "domain": "supply-chain" 与描述性要求不一致。
相比之下，以下内容从（即产生）给定输出中获取线索：
.data.assets |=
map( if any(.tags[].value; . == "sourcing") then . + "domain":"sourcing"
elif any(.tags[].value; . == "supply-chain") then . + "domain":"supply-chain"
else . end )
将“域”设置为所有标签值
.data.assets |= map( .domain += [.tags[].value] )
【讨论】：
这正是我要找的！ 100% 达到了我的目的。太感谢了。但是我无法从 bash 脚本中运行这个命令？哪里不对了？echo $response | jq .data.assets |= map( if any(.tags[].value; . == "sourcing") then . + "domain":"sourcing" else . end )
您必须添加合适的引号（例如 echo “$response” | jq ‘...’），或使用 -f 命令行选项。详见jq手册。
之前是我的错。我更正了引号，它的作用就像魅力一样。点赞！我有大约 6 个elif 条件。为避免这种情况，是否可以像arr["marketing","supply-chain","sourcing"]那样声明数组并比较并获得相同的输出？
是的，一旦你掌握了 jq 的基础知识，这是可能的，而且很容易做到。同时，您表示打算投票......
我投了赞成票。他们说现在看不到！以上是关于jq 内部数组值作为数组外的新键的主要内容，如果未能解决你的问题，请参考以下文章
