在发送到数据库之前操作 json

Question

我正在使用 node 和 airtable.js 从 Airtable API 中提取一些数据。我在 airtable 数据库中使用链接字段。数据如下：

{
            "id": "recct1MELnXEJGj6Z",
            "fields": {
                "Household": "Betts",
                "Guests": [
                    "recWONC10o06E4IN0",
                    "recLwxndGevZ7HeUG"
                ],
                "Name (from Guests)": [
                    "Margaret",
                    "Terry"
                ]
            },
            "createdTime": "2021-09-11T15:48:51.000Z"
        }

我想在推送到 MongoDB 数据库之前重新格式化，使其看起来像这样：

    {
            "id": "recct1MELnXEJGj6Z",
            "Household": "Betts",
            "Guests": [
                {
                 "_id" : "recWONC10o06E4IN0",
                 "name" : "Margaret"
                 },
                {"_id" : "recLwxndGevZ7HeUG",
                 "name" : "Terry"
                },
              ],
            "createdTime": "2021-09-11T15:48:51.000Z"
        }

您基本上需要从fields对象中提取键和值，直接将它们分配给JSON，然后删除fields对象。

const json = {
  "id": "recct1MELnXEJGj6Z",
  "fields": {
      "Household": "Betts",
      "Guests": [
          "recWONC10o06E4IN0",
          "recLwxndGevZ7HeUG"
      ],
      "Name (from Guests)": [
          "Margaret",
          "Terry"
      ]
  },
  "createdTime": "2021-09-11T15:48:51.000Z"
}

Object.entries(json.fields).forEach(([key, value]) => (json[key] = value));
delete json.fields;

console.log(json);

或者你可以像这样创建一个新的 JSON 对象：

const json = {
  "id": "recct1MELnXEJGj6Z",
  "fields": {
      "Household": "Betts",
      "Guests": [
          "recWONC10o06E4IN0",
          "recLwxndGevZ7HeUG"
      ],
      "Name (from Guests)": [
          "Margaret",
          "Terry"
      ]
  },
  "createdTime": "2021-09-11T15:48:51.000Z"
}

const newJson = {...json, ...json.fields};
delete newJson.fields;
console.log(newJson);
