通过jq从嵌套json返回条目

Question

对于给定的 json：

{
  "source_1": [
    {
      "val1": "foo1",
      "val2": "bar1"
    },
    {
      "val1": "foo2",
      "val2": "bar2"
    }
  ],
  "source_2": [
    {
      "val1": "foo1",
      "val2": "bar1"
    },
    {
      "val1": "foo3",
      "val2": "bar3"
    }
  ]
}

我想在

val2

==

bar1

处递归搜索它，但以这种格式返回它：

{
  "source_1": [
    {
      "val1": "foo1",
      "val2": "bar1"
    }
  ],
  "source_2": [
    {
      "val1": "foo1",
      "val2": "bar1"
    }
  ]
}

Answer 1

这会产生您预期的输出：

map_values(map(select(.val2 == "bar1")))
