I'm a newbie to Node JS and I'm trying to get the data from this URL: https://www.tiktok.com/node/share/user/@test/

You don't need to sign into anything to look at the data, you can literally click the link and you see the data I want to access. However, when I try to use node-fetch to retrieve this data so I can use it, I get a weird response (or, in better terms, I don't know what it means lol)

This is the code I used.

const fetch = require('node-fetch')

fetch("https://www.tiktok.com/node/share/user/@test/")
.then(res => {
  console.log(res);
})

I looked through this whole thing and can't quite understand what it means. Sorry for asking but yeah

CodePudding user response：

What you're looking at is the Response object which represents the entire HTTP response. If you're only interested in the JSON data, you can extract it using the Response.json() method:

const fetch = require("node-fetch");

// you'll get an "invalid json response body" error without this
const headers = { "User-Agent": "node-fetch" };

const response = fetch("https://www.tiktok.com/node/share/user/@test", {
  headers,
})
  // first, extract JSON data from `Response` object
  .then((res) => res.json())
  // then print JSON data that was parsed
  .then((data) => console.log(data));
