Soundcloud embed stream URL (Node, JSON)
I'm currently using Node to scrape a blog that stores selected data in a JSON file. When scraping a blog post that contains an embedded track from Soundcloud I seem to only be able to collect the iframe src and not that actual track link (either soundcloud link or stream link).
When I scrape the iframe src url I seem to only be able to get a link that's in the following format: https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/120261008&color=000000&auto_play=false&show_artwork=false
If I'm not able to scrape the track URL is there a way I'm able to manipulate how the above link is stored into the array? In order for this link to be usable I need to only store the url=https%3A//api.soundcloud.com/tracks/120261008 (minus the url=).
But then the problem with this is that the %3A needs replacing to a :
What's the best way to manipulate the url to achieve the desired output url either when it's being stored or when it's being called?
I'm not exactly sure what you're planning on doing with the track URL once you have it, but to get the permalink URL for a track/playlist your going to need a two step approach. First you're going to need to parse the url parameter in the query string in the iframe src:
CLIENT_ID = 'client_id=b45b1aa10f1ac2941910a7f0d10f8e28';
var src = 'https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/120261008&color=000000&auto_play=false&show_artwork=false',
match = src.match(/url=([^&]*)/),
resource = match[0],
stream = decodeURIComponent(match[1])+'/stream/?'+CLIENT_ID;
Then you're going to need to make an HTTP request to SoundCloud's resolve API to actually convert that resource into the permalink URL:
var url = 'http://api.soundcloud.com/resolve.json?'+resource+'&'+CLIENT_ID;
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.onload = function(){
var data = JSON.parse(xhr.responseText);
// do something with the data
console.log(data.permalink_url);
};
xhr.send();
