Javascript java脚本将嵌套对象提升到根级别

我得到了一个json对象，如下所示：

{
  "total": 298,
  "max_score": 5.2472496,
  "hits": [
    {
      "_index": "kafkajmx2",
      "_type": "logs",
      "_id": "AVo-VsUdponm9zQGYYS5",
      "_score": 5.2472496,
      "_source": {
        "metric_value_number": 134,
        "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
        "@timestamp": "2017-02-14T20:35:58.266Z",
        "metric_name": "IsrExpandsPerSec.Count",
        "@version": "1",
        "host": "localhost",
        "metric_type": "ReplicaManager",
        "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
        "type": null,
        "metric_node": "node1.kafka.server"
      }
    },
    {
      "_index": "kafkajmx2",
      "_type": "logs",
      "_id": "AVo-V69Yponm9zQGYYwS",
      "_score": 5.2472496,
      "_source": {
        "metric_value_number": 134,
        "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
        "@timestamp": "2017-02-14T20:36:58.216Z",
        "metric_name": "IsrExpandsPerSec.Count",
        "@version": "1",
        "host": "localhost",
        "metric_type": "ReplicaManager",
        "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
        "type": null,
        "metric_node": "node1.kafka.server"
      }
    }
]
}

{
            "metric_value_number": 134,
            "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
            "@timestamp": "2017-02-14T20:36:58.216Z",
            "metric_name": "IsrExpandsPerSec.Count",
            "@version": "1",
            "host": "localhost",
            "metric_type": "ReplicaManager",
            "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
            "type": null,
            "metric_node": "aesdp0101.kafka.server"
          },
{
            "metric_value_number": 134,
            "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
            "@timestamp": "2017-02-14T20:35:58.266Z",
            "metric_name": "IsrExpandsPerSec.Count",
            "@version": "1",
            "host": "localhost",
            "metric_type": "ReplicaManager",
            "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
            "type": null,
            "metric_node": "aesdp0101.kafka.server"
          }

我要做的是将

\u source

对象调到根级别，如下所示：

{
  "total": 298,
  "max_score": 5.2472496,
  "hits": [
    {
      "_index": "kafkajmx2",

      "_id": "AVo-VsUdponm9zQGYYS5",
      "_score": 5.2472496,
      "_source": {
        "metric_value_number": 134,
        "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
        "@timestamp": "2017-02-14T20:35:58.266Z",
        "metric_name": "IsrExpandsPerSec.Count",
        "@version": "1",
        "host": "localhost",
        "metric_type": "ReplicaManager",
        "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
        "type": null,
        "metric_node": "node1.kafka.server"
      }
    },
    {
      "_index": "kafkajmx2",
      "_type": "logs",
      "_id": "AVo-V69Yponm9zQGYYwS",
      "_score": 5.2472496,
      "_source": {
        "metric_value_number": 134,
        "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
        "@timestamp": "2017-02-14T20:36:58.216Z",
        "metric_name": "IsrExpandsPerSec.Count",
        "@version": "1",
        "host": "localhost",
        "metric_type": "ReplicaManager",
        "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
        "type": null,
        "metric_node": "node1.kafka.server"
      }
    }
]
}

{
            "metric_value_number": 134,
            "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
            "@timestamp": "2017-02-14T20:36:58.216Z",
            "metric_name": "IsrExpandsPerSec.Count",
            "@version": "1",
            "host": "localhost",
            "metric_type": "ReplicaManager",
            "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
            "type": null,
            "metric_node": "aesdp0101.kafka.server"
          },
{
            "metric_value_number": 134,
            "path": "/home/usrxxx/logstash-5.2.0/bin/jmxconf",
            "@timestamp": "2017-02-14T20:35:58.266Z",
            "metric_name": "IsrExpandsPerSec.Count",
            "@version": "1",
            "host": "localhost",
            "metric_type": "ReplicaManager",
            "metric_path": "node1.kafka.server:type=ReplicaManager,name=IsrExpandsPerSec.Count",
            "type": null,
            "metric_node": "aesdp0101.kafka.server"
          }

我不知道如何在javascript中本机实现这一点，或者lodash中是否也有实现这一点的方法

我试过这样做，但我认为

\u源代码中的
\u
会影响代码吗

      var metricData = [];
      for (var i=0; i < response.length; i++) {

         metricData.push(response[i]._source);
         console.log("metric data: ", metricData);

      };

var metricData=[]；
对于（变量i=0；i
您忘记选择“点击”了吗

请尝试以下操作：

metricData = response.hits.map(hit => hit["_source"])

你忘了选择“点击率”了吗

请尝试以下操作：

metricData = response.hits.map(hit => hit["_source"])

你的问题中没有数组
metricData
。对不起，忘了包括这个，我在代码中有一个
var metricData=[]
，做了编辑…见下面的答案，看起来是正确的。你的问题中没有数组

TypeError:response.hits.map不是一个函数时出现了此错误。
响应对象是什么？您没有提到这一点。我怀疑您应该从中选择json数据。或者您给了我们错误的响应格式和“hits”不是数组。对不起…我的输入错误…再一次…我在这里工作了一天…但它起了作用，非常感谢！我在尝试时遇到了这个错误…
