【问题描述】：

我需要将从服务器获取的数据导出为 .txt 文件

我得到的结构是这样的：

{
  "value": {
    "name": "A",
    "mandatory": true,
    "contentMandatory": true,
    "multipleAllowed": false,
    "fixed": true
  },
  "children": [
    {
      "value": {
        "name": "Aa",
        "mandatory": false,
        "contentMandatory": true,
        "multipleAllowed": false,
        "mergeStrategy": {
          "_type": "PrioritizedSourceStrategy"
        },
        "fixed": false
      },
      "children": [
        {
          "value": {
            "name": "Aaa",
            "mandatory": false,
            "contentMandatory": false,
            "multipleAllowed": true,
            "fixed": false
          },
          "children": [
            {
              "value": {
                "name": "AaaA",
                "mandatory": true,
                "contentMandatory": true,
                "multipleAllowed": false,
                "fixed": false
              },
              "children": []
            }
          ]
        },
        {
          "value": {
            "name": "AaB",
            "mandatory": false,
            "contentMandatory": false,
            "multipleAllowed": true,
            "fixed": false
          },
          "children": [
            {
              "value": {
                "name": "AaBa",
                "mandatory": true,
                "contentMandatory": true,
                "multipleAllowed": false,
                "fixed": false
              },
              "children": []
            }
          ]
        }
      ]
    }
      ...
    }
  ]
}

但我需要结构在文件中看起来像这样：

"name": "A", "mandatory": true, "contentMandatory": true, "multipleAllowed": false,
  "name": "Aa", "mandatory": false, "contentMandatory": true,  "multipleAllowed": false, "mergeStrategy": { "_type": "PrioritizedSourceStrategy"}
    "name": "Aaa", "mandatory": false, "contentMandatory": false, "multipleAllowed": true,
      "name": "AaaA", "mandatory": true, "contentMandatory": true, "multipleAllowed": false,
    "name": "AaB", "mandatory": false, "contentMandatory": false, "multipleAllowed": true,
       "name": "AaBa", "mandatory": true, "contentMandatory": true, "multipleAllowed": false,
...

所以我需要删除一些对象字段（如“固定”）并显示每个对象一行中留下的字段。归档此结果的最佳方式是什么？

【问题讨论】：

不知道你觉得如何创建 txt 文件，但你可能需要这样的东西：JSON.stringify(YOUR_DATA).replaceAll('"name": ', '\n"name": ')。这会在每个子字符串 'name: ' 之前添加一个断线 '\n'。

【解决方案1】：

你想要的结构是错误的，因为你有重复的属性。如果这是您想要的结构：

{
"name": "A",
"mandatory": true,
"contentMandatory": true,
"multipleAllowed": false,
"children": [
    {
    "name": "Aa",
    "mandatory": false,
    "contentMandatory": true,
    "multipleAllowed": false,
    "mergeStrategy": { "_type": "PrioritizedSourceStrategy" },
    "children": [
        {
        "name": "Aaa",
        "mandatory": false,
        "contentMandatory": false,
        "multipleAllowed": true,
        "children": [
            {
            "name": "AaaA",
            "mandatory": true,
            "contentMandatory": true,
            "multipleAllowed": false
            }
        ]
        },
        {
        "name": "AaB",
        "mandatory": false,
        "contentMandatory": false,
        "multipleAllowed": true,
        "children": [
            {
            "name": "AaBa",
            "mandatory": true,
            "contentMandatory": true,
            "multipleAllowed": false
            }
        ]
        }
    ]
    }
]
}

然后使用这段代码sn-p：

var parsedObject = parse(obj)

function parse(obj) {
   let children = obj.children.map(child => parse(child))
   return { name, mandatory, contentMandatory, multipleAllowed, mergeStrategy, children } = {...obj.value, children}
}

我正在使用地图和对象解构来保留我想要的属性。
