【问题描述】：

我有一种格式的 json 数据，需要编辑成 Firebase 支持的格式。我创建了一个带有尝试编辑数据格式的功能的 javascript 应用程序，但似乎不起作用。这是一个大量的数据，但下面是一个示例。

app.js 应用程序

var fs = require('fs');

//read data from file
var readData = fs.readFileSync('readMe.json','utf8');
var sample = JSON.parse(readData);

var newData =addFirebaseKey(sample);


// output datda to output.json
fs.writeFileSync('output.json',JSON.stringify(newData),'utf8');

function addFirebaseKey(contacts)
    var fireContacts="";
    for(var i=0;i<contacts.length;i++)
        var tempObj=contacts[i];

    //tel number is also the firebase key
        var fireKey =tempObj.tel;

        fireContacts=fireContacts+fireKey+tempObj;
    
    return fireContacts;

readMe.json 文件

[
  
    "contactName": "Office of the President",
    "description": "office of president",
    "fax": "-",
    "location": "Lusaka",
    "postalAddress": "-",
    "tel": "123456",
    "country": "Zambia"
  ,
  
    "contactName": "State House",
    "description": "State president, Ministry of",
    "fax": "-",
    "location": "Lusaka",
    "postalAddress": "-",
    "tel": "444900",
    "country": "Zambia"
  ,
  
    "contactName": "National Strategy Office",
    "description": "national strategy",
    "fax": "-",
    "location": "Gaborone",
    "postalAddress": "-",
    "tel": "222222",
    "country": "Zambia"
  
]

output.json 文件

"123456[object Object]444900[object Object]222222[object Object]"

这是 Firebase 所需的格式

  "contactDetail" : 
    "Zambia" : 
      "123456" : 
        "contactName" : "Shocks & Exhaust Fitment Centre",
        "description" : "motor vehicle exhaust systems",
        "fax" : "-",
        "location" : "Lusaka",
        "postalAddress" : "NA",
        "tel" : "123456"
      ,
      "888555" : 
        "contactName" : "K Media",
        "description" : "internet marketing",
        "fax" : "-",
        "location" : "Lusaka",
        "postalAddress" : "P O Box 26249, Gaborone",
        "tel" : "888555"
      ,
      "555544" : 
        "contactName" : "Shocks & Exhaust Fitment Centre",
        "description" : "secretarial services",
        "fax" : "-",
        "location" : "Lusaka",
        "postalAddress" : "NA",
        "tel" : "555544"
      
    
  

【参考方案1】：

转换数据格式：

let input = [
  
    "contactName": "Office of the President",
    "description": "office of president",
    "fax": "-",
    "location": "Lusaka",
    "postalAddress": "-",
    "tel": "123456",
    "country": "Zambia"
  ,
  
    "contactName": "State House",
    "description": "State president, Ministry of",
    "fax": "-",
    "location": "Lusaka",
    "postalAddress": "-",
    "tel": "444900",
    "country": "Zambia"
  ,
  
    "contactName": "National Strategy Office",
    "description": "national strategy",
    "fax": "-",
    "location": "Gaborone",
    "postalAddress": "-",
    "tel": "222222",
    "country": "Zambia"
  
];

let output = ;
input.forEach((row) => 
  if (!output[row.country]) output[row.country] = ;
  output[row.country][row.tel] = row;
)
console.log(output);

之后，您需要将其写入 Firebase 或文件。

【讨论】：

我添加了此代码，因为赞比亚需要用引号括起来，并且还要将输出从单引号更改为双引号 var a =output.toString().replace(/'/g, '"'); var b = JSON.stringify(output); console.log(b);
