我尝试使用jsonslurper解析从groovy的elastic-search api中获取的以下json。我需要从该json中创建一个_id列表。尝试了多种代码变体，但没有成功
请建议，任何帮助都感激不尽。

{
  "took" : 2535,
  "timed_out" : false,
  "_shards" : {
    "total" : 384,
    "successful" : 384,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 10000,
      "relation" : "gte"
    },
    "max_score" : null,
    "hits" : [
      {
        "_index" : "X",
        "_type" : "_doc",
        "_id" : "310165903526204",
        "_score" : null,
        "sort" : [
          "310165903526204"
        ]
      },
      {
        "_index" : "X",
        "_type" : "_doc",
        "_id" : "310165903698515",
        "_score" : null,
        "sort" : [
          "310165903698515"
        ]
      },
      {
        "_index" : "X",
        "_type" : "_doc",
      **"_id" : "310165903819494"**,
        "_score" : null,
        "sort" : [
          "310165903819494"
        ]
      }
    ]
  }
}

PS：我尝试使用elasticsearch提供的多个客户端来搜索ES和解析数据，但我面临着另一个问题，所以不得不切换到HTTP客户端并手动解析。这是客户端问题RestHighLevelClient with Elasticsearch client error的链接

    ]
  }
}

有了这个更新的Json，我想在providers下的typeId中提取mostSigBits和leastSigBits值。但问题是我只想在providers[]中提取那个typeID，它没有_1或_2或任何后缀。
我已经尝试通过这样做来获得数据，但正在寻找一些更好的方法

json.点击数.点击数[0]._源.位置.提供程序[0].类型Id
