如何将JSON数据映射到类 [英] How to map JSON data to a class

问题描述

我通过 Babel 创建了一个ES6课程，我想要映射从服务器获取的JSON数据到ES6课程。

有什么常见的方法吗？

I created a ES6 class by Babel and I want to map JSON data which is gotten from a server to the ES6 class.
Is there anything common way to do that?

User.js

export default class User {
  constructor() {
    this.firstName;
    this.lastName;
    this.sex;
  }
}

app.js

import User from "./classes/User";

var data = JSON.parse(req.responseText);
console.log(data.firstname); //Bob
//now...just set data one by one?

推荐答案

我会将JSON对象合并到此使用 Object.assign ，如下所示：

I would merge the JSON object into this using Object.assign, as follows:

class User {
  firstName;
  lastName;
  sex;

  constructor(data) {
    Object.assign(this, data);
//  ^^^^^^^^^^^^^^^^^^^^^^^^^^
  }
}

var data = JSON.parse(req.responseText);
new User(data);
