Javascript 如何获取请求后JSON，然后使用Node.js更改JSON格式？

我有一个JSON格式的传入Post请求，如下所示：

[{"username":"ali","hair_color":"brown","height":1.2},{"username":"marc","hair_color":"blue","height":1.4},{"username":"zehua","hair_color":"black","height":1.8}]

我想将其更改为这种格式，然后将其发送到RESTFUL API：

{"h":["username","hair_color","height"],"d":[["ali","brown",1.2],["marc","blue",1.4],["zehua","black",1.8]]}

问题是如何在不考虑不同参数名称的情况下更改JSON格式，“

h

”表示参数名称，“

d

”表示值

下面是我的js代码：

var express = require("express");
var myParser = require("body-parser");
var app = express();

app.use(myParser.urlencoded({extended : true}));
app.use(myParser.json());

app.post("/parseJSON", function(request, response) {
    console.log(request.body); //This prints the JSON document received (if it is a JSON document)
    if(request.body.constructor === Object && Object.keys(request.body).length === 0)
    {
        response.end("-1");
    }
    else
    {
        response.end("0");
    }
});
app.get("/parseJSON", function(request, response) {
    console.log(request.body); //This prints the JSON document received (if it is a JSON document)
    if(request.body.constructor === Object && Object.keys(request.body).length === 0)
    {
        response.end("-1");
    }
    else
    {
        response.end("0");
    }
});

app.listen(8080);

你能试试吗

var key = Object.keys(request.body[0])
var data = request.body.map(ele => {
 return Object.values(ele);
})
var result = {h:key,d:data};

你好！已经编辑了我的问题。请检查一下，并请给我一个关于这个问题的答案@Ankh

const h = Object.keys(request.body[0])
const d = request.body.map(ele => Object.values(ele))  // Use ES7 to enable using Object.values()

const result = {h, d};
