javascript - 如何在React js中解析本地JSON文件？

Question

如何解析 JSON 文件，检索其所有数据并在我的代码中使用它？

我尝试导入文件并尝试控制台记录它，但它所做的只是打印 Object {}:

import jsonData from "./file.json";
console.log(jsonData);

这就是我的 file.json 的样子:

[
    {
      "id": 1,
      "gender": "Female",
      "first_name": "Helen",
      "last_name": "Nguyen",
      "email": "hnguyen0@bloomberg.com",
      "ip_address": "227.211.25.18"
    }, {
      "id": 2,
      "gender": "Male",
      "first_name": "Carlos",
      "last_name": "Fowler",
      "email": "cfowler1@gnu.org",
      "ip_address": "214.248.201.11"
    }
]

我希望能够访问每个组件的名字和姓氏，并将其打印在网站上。

var data = require('../../file.json'); // forward slashes will depend on the file location

var data = [
    {
      "id": 1,
      "gender": "Female",
      "first_name": "Helen",
      "last_name": "Nguyen",
      "email": "hnguyen0@bloomberg.com",
      "ip_address": "227.211.25.18"
    }, {
      "id": 2,
      "gender": "Male",
      "first_name": "Carlos",
      "last_name": "Fowler",
      "email": "cfowler1@gnu.org",
      "ip_address": "214.248.201.11"
    }
];

for (var i = 0; i < data.length; i++)
{
    var obj = data[i];
    console.log(`Name: ${obj.last_name}, ${obj.first_name}`);
}
