将{Object}的嵌套[Array]转换为> {Object} | JSON文件

Question

我是JSON数据操作的新手，我需要一些帮助。

我有一个JSON文件，如下所示：

[
  {
    "plannification": {
      "Data": 1,
      "DataType": "GB",
      "InclusionOption1": ".",
      "Default": false,
      "PropositionId": "GBT13456",
      "EssentialLink": "greatpdf.com/pdf.pdf",
      "Term": "1",
      "Segment": "part",
      "Id": "653284",
    }
  },
  {
    "plannification": {
      "Data": 1,
      "DataType": "FR",
      "inclusionOption1": ".",
      "default": false,
      "PropositionId": "FRT13456",
      "EssentialLink": "greatpdf.com/pdf2.pdf",
      "term": "1",
      "Segment": "pro",
      "Id": "984532",
    }
  }
]

我想将这个文件转换为object，并且只从"Segment": “pro”,中提取数据，如下所示：

    {
      984532:{
      Segment: "pro",
      EssentialLink: "greatpdf.com/pdf.pdf",
      PropositionId: "FRT13456",
     },
      etc.. {},
}

我该从哪里开始呢？

Answer 1

您可以在值为pro的Segment上使用array#filter筛选数组。可以使用array#reduce遍历数组，然后使用Object#values()取出每个对象的值并创建新对象。

const data = [{ "plannification": { "Data": 1, "DataType": "GB", "InclusionOption1": ".", "Default": false, "PropositionId": "GBT13456", "EssentialLink": "greatpdf.com/pdf.pdf", "Term": "1", "Segment": "part", "Id": "653284" } }, { "plannification": { "Data": 1, "DataType":"FR", "inclusionOption1": ".", "default": false, "PropositionId": "FRT13456", "EssentialLink": "greatpdf.com/pdf2.pdf", "term": "1", "Segment": "pro", "Id": "984532", } } ],
      result = data.filter(o => {
        let { Segment } = Object.values(o)[0];
        return Segment === 'pro';
      }).reduce((r,o) => {
        let { Id, Segment, PropositionId, EssentialLink } = Object.values(o)[0];
        r[Id] = { Segment, PropositionId, EssentialLink };
        return r;
      },{})
console.log(result);

Answer 2

1-读取json文件

2-迭代对象数组

3-对于每个对象，检查所需的属性

4-如果它与您想要的匹配，则读取对象的属性并构造对象

Answer 3

您的数据结构无效，请先更正您编写json对象数组的方式，这样我才能找出
