Question

我需要将下面的对象转换为另一个对象，以使其与Elasticsearch DSL兼容。我尝试了各种方法，但似乎没有一种方法可以返回准确的结果。我的主要问题是将具有公共键的对象转换为数组。这是我的数据：

{
  "aggs": {
    "country_groups": {
      "terms": {
        "field": "country.keyword",
        "size": 30000
      },
      "aggs": {
        "max_price_and_id": {
          "top_hits": {
            "size": 1,
            "sort": {
              "video_count": "desc"
            },
            "_source": ["channel_id", "video_count"]
          }
        }
      }
    }
  }
}

我需要将其转换为以下格式：

[
   {
      "must":{
         "match":{
            "customer_name":{
               "query":"",
               "operator":"and"
            }
         }
      }
   },
   {
      "should":{
         "match":{
            "customer_name":{
               "query":"",
               "operator":"and"
            }
         }
      }
   },
   {
      "should":{
         "match":{
            "customer_name":{
               "query":"",
               "operator":"and"
            }
         }
      }
   }
]

Answer 1

我没有关于您的问题的太多信息，但是此代码段适用于您的数据集。 ìnputJSON是包含您的数据的JSON文件。

var resultJSON = {}
resultJSON["query"]={}
resultJSON["query"]["bool"] = {}
resultJSON["query"]["bool"]["should"] = []
resultJSON["query"]["bool"]["must"] = {}
resultJSON["query"]["bool"]["minimum_should_match"] = 1
var source = inputJSON
source.forEach(currentElement =>{
    if(currentElement["must"]!=undefined){
        resultJSON["query"]["bool"]["must"] = currentElement["must"]
    }
    if(currentElement["should"]!=undefined){
        resultJSON["query"]["bool"]["should"].push(currentElement["should"])
    }
})

返回：

{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "customer_name": {
              "query": "",
              "operator": "and"
            }
          }
        },
        {
          "match": {
            "customer_name": {
              "query": "",
              "operator": "and"
            }
          }
        }
      ],
      "must": {
        "match": {
          "customer_name": {
            "query": "",
            "operator": "and"
          }
        }
      },
      "minimum_should_match": 1
    }
  }
}

const obj = [
  {
    "must":{
        "match":{
          "customer_name":{
              "query":"",
              "operator":"and"
          }
        }enter code here

    },
  },
  {
    "should":{
        "match":{
          "customer_name":{
              "query":"",
              "operator":"and"
          }
        }
    }
  },
  {
    "should":{
        "match":{
          "customer_name":{
              "query":"",
              "operator":"and"
          }
        }
    }
  }
]
let resultTemplate = {
  query: {
    bool: {
      must: {},
      should: [],
      minimum_should_match: 1,
    },
  },
};

const converter = (source) => {
  source.forEach((item) => {
    let iKeys = Object.keys(item);
    iKeys.forEach((key) => {
      if (key === 'must') {
        resultTemplate.query.bool[key] = item[key];
      } else {
        resultTemplate.query.bool[key].push(item[key]);
      }
    });
  });
};

converter(obj);
console.log(resultTemplate);
