Node.js：使用“ @”-符号解析json-ld / JSON

Question

I have a JSON that looks like this:

{"marker":[{"@attributes":{"start":"Im Berge",
"finish":"Eichelberger Stra\u00dfe"
...

I am trying to parse the attributes inside the "@attributes", but have not found a way to do it. What I tried so far:

const fs = require('fs');  
var jsonObj = JSON.parse(fs.readFileSync('route1.json', 'utf8'));  
console.log(jsonObj['@attributes']);

Also tried the same with

console.log(jsonObj.marker['@attributes']);

Neither of which work. I understand that this is supposed to be a json-ld and that I'm supposed to parse an object with an "@" sign with ['@attributes'], but either way I always get an error or undefined. I got the JSON from an API I wanna use and it is in there multiple times, so I have no way around it.

Answer 1

.marker is an array so:

console.log(jsonObj.marker[0]['@attributes']);

But you may want to loop through it:

jsonObj.marker.forEach(marker => console.log(marker['@attributes']));

You can require a JSON file, instead of JSON.parse & fs.readFileSync

var jsonObj = require('./route1.json');
