提取本地JSON [英] Fetching local JSON

问题描述

如何获取目录中的本地JSON文件?

How can I fetch a local JSON file that is in my directory?

JSON文件如下所示:

the JSON file looks like this:

[
  {
    "name": "Sara",
     "id": 3232
   },
  {
    "name": "Jim",
     "id": 2342
   },
  {
     "name": "Pete",
      "id": 532532
   }
]

如果我在尝试使用的同一个文件中包含json信息，则效果很好，但是如果我想将其引入，那么我就无法一辈子让它正常工作并保持读为未定义.

If I have the json information inside the same file I'm trying to use it, it works beautifully, but if I want to bring it in, I can't for the life of me get it to work and it keeps reading it as undefined.

这是我所拥有的

getData() {


    var json_data = require('../services/contributors.JSON');


    for (var i in json_data){
    console.log('Name: ' + json_data[i]["name"])

    }


}

您能看到我在做什么吗?我正在尝试让它做出反应，所以反应可能会有所不同吗?我不知道.任何帮助将不胜感激.谢谢！

Can you see what I'm doing wrong? I'm trying to get this into react so maybe react works differently? I don't know. Any help will be appreciated. Thank you!

推荐答案

尝试使用文件系统.不要以为从JSON文件中读取内容就是这样.

Try to use file system. Don't think reading from a JSON file works like that.

const fs = require('fs');
const json_data = require('../services/contributors.JSON');

fs.readFile(json_data, 'utf8', function (err, data) {
  try {
    data = JSON.parse(data)
    for (let i in data){
    console.log('Name:',data[i].name)
    }
  } catch (e) {
    // Catch error in case file doesn't exist or isn't valid JSON
  }
});
