从Lowdb数据库获取价值

Question

我想从带有lowdb的json文件中恢复一个值。我尝试了几种使用find和filter的方法，但是没有成功。

我的json文件与此类似：

{
  "437581472976701696": [
    {
      "messageidofmainmessage": "584013718974957588"
    },
    {
      "channelidofmainmessage": "583930963118516741"
    },
    {
      "user_id": "209567566058753035",
      "user_name": "kekedoe",
      "stape": "1"
    },
    {
      "user_id": "209567759058753074",
      "user_name": "iekjjye",
      "stape": "3"
    }
  ],
  "187581471043865280": [
    {
      "messageidofmainmessage": "784013717114957582"
    },
    {
      "channelidofmainmessage": "783930964718516748"
    },
    {
      "user_id": "209567566058753018",
      "user_name": "egegeer",
      "stape": "2"
    },
    {
      "user_id": "509567759058753482",
      "user_name": "dfgdge",
      "stape": "4"
    }
  ]
}

我想获取user_name字段的父级。例如，如果我问“ user_name”的父母：“ egegeer”，他还给我“ 187581471043865280”
