SharePoint Node/Lobby

Good day, @s-KaiNet . I have been using sp-request to scrape pages within a site collections on SP2013 for a couple years now. I now need to update my node code to work with SPO, app-only permissions. I'm able to authenticate to SPO without issue however, the same technique to grab the HTML of a SP page no longer works.

With SP2013, I could simply pass the full URL and the response would return the HTML. When I try the same with SPO I get an authentication error. Here's the current code:

/*jshint esversion: 6 */

const sprequest = require('sp-request');

let spr = sprequest.create({
  siteUrl: 'https://tenant.org/sites/dev',
  clientId: '1beab0a4-a10d-4a6b-xxxx-b4c247faa95f',
  clientSecret: 'SZvu9Gmbxxxx9fHGeZ+KC9QBxxxx1ApHAlLeNAermug='
});

const url = encodeURI('https://tenant.org/sites/dev');

function peek(url) {
  url = url.toLowerCase();
  return new Promise(function () {
    spr(url)
      .then(function (response) {

        console.log(response.body);
      })
      .catch(function (err) {
        console.log('Something went wrong.... ' + err);
      });
  });
}

peek(url);
