My Question or Issue
Hi,
I'm creating a bot using the Spotify API. This bot should update one of my playlist by adding a specific song.
My problem is that I cannot obtain an access token with the /authorize endpoint.
Here's my code :
function getToken() {
let generateRandomString = function (length) {
let text = '';
let possible = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
for (let i = 0; i < length; i++) {
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text;
};
let spotifyApi = new SpotifyWebApi({
clientId: data.spotify.client_id,
redirectUri: data.spotify.redirect_uri
});
/**
* Authenticating the app to Spotify Web API
* @type {string[]}
*/
let scopes = ['user-read-private', 'user-read-email', 'playlist-modify-public'],
state = generateRandomString(16);
// Create the authorization URL
let authorizeURL = spotifyApi.createAuthorizeURL(scopes, state, false);
//Obtained URL -> https://accounts.spotify.com/authorize?client_id=516af068412341e69675da2c0f364846&response_type=code&redirect_uri=http://localhost:8888/callback&scope=user-read-private%20user-read-email%20playlist-modify-public&state=SEdtlgsP8aECVurs&show_dialog=false
// Create request to the callback Express route
https.get(authorizeURL, response => {
if (response) {
return console.log(response);
}
}).on('error', err => {
console.error(err);
});
}
When I process the GET request to authenticate my app (see the https.get part above) and when I check what is given in my console (output given by the return console.log(response)), I get that :
...
responseUrl: 'https://accounts.spotify.com/login?continue=https%3A%2F%2Faccounts.spotify.com%2Fauthorize%3Fscope%3Duser-read-private%2Buser-read-email%2Bplaylist-modify-public%26response_type%3Dcode%26redirect_uri%3Dhttp%253A%252F%252Flocalhost%253A8888%252Fcallback%26state%3DlD3Ijyz5ucTZ9L5B%26client_id%3D516af068412341e69675da2c0f364846%26show_dialog%3Dfalse',
...
This is the reponse URL I have. It seems that I'm not logged, thus I cannot access the Spotify Web API.
My callback route is working since I can copy/paste the authorizeUrl in a browser, and I'll get the token written in a text file. It's only when I try to process a request with https.get that it doesn't work.
If the API prompt me for login, then why is there an CLIENT_ID and CLIENT_SECRET since there not used ?
Any idea ?
Thanks in advance
EDIT : fixed obtained URL since it wasn't what I obtained ^^
