仅保留具有字符串值的字段 [英] Leave only fields with string values

问题描述

我有一个像这样的JSON结构:

I have a JSON structure like this:

{
  "1": "a-secret",
  "A": "b-secret",
  "2": {
    "3": "ab-secret",
    "4": {
      "5": "adc-secret"
    },
    "6": {
      "7": "abdc-secret"
    }
  }
}

我正在尝试创建一个命令(最好是一个划线员)以返回仅具有字符串值的密钥对.因此，对于以上内容，它将返回:

I am trying to create a command (preferable one liner) to return key pairs that only have string values. So for the above it would return:

{
  "1": "a-secret",
  "A": "b-secret"
}

我发现.[]|strings仅返回字符串值，但是我既需要键又需要值，这就是我的绊脚石！

I have found .[]|strings that returns only the string values but I need both the key and value and that's where I'm stumped!

You are looking for map_values.

$ jq 'map_values(strings)' file
{
  "1": "a-secret",
  "A": "b-secret"
}
