Question

我有一个json文件我需要这个文件到我的json代码，我需要在一个对象数组中解析它这例如是json文件

{
  "movies": [
    {
      "title": "Star Wars",
      "year": 1977,
      "director": "George Lucas"
    },
    {
      "title": "The Empire Strikes Back",
      "year": 1980,
      "director": "Irvin Kershner"
    },
    {
      "title": "Return of the Jedi",
      "year": 1983,
      "director": "Richard Marquand"
    }]
}

我希望将其转换为此数组

[{title:"Star Wars", year:1977, director:"George Lucas"},{},{}]

Answer 1

只需读出电影属性：

var parsedJSON = require('./filename.json');
var result = parsedJSON.movies;

Answer 2

您可以使用JSON.parse(..)解析文件字符串：

const  fs = require('fs');

var fileString = fs.readFileSync('movies.txt').toString();
var fileObj = JSON.parse(fileString);
var moviesArr = fileObj.movies;
console.log(moviesArr);
