"Invalid access token, reason: None" with access token from OAuth

[alansberman]

I'm new to both Django and spotipy, and am trying to get my currently playing track.

This is what I have thus far:

def home(request):
	sp = spotipy.Spotify(auth_manager=SpotifyOAuth(client_id="<my_token>",
                                               client_secret="<my_secret>",
                                               redirect_uri="http://localhost:8000/callback/",
                                               scope="user-library-read user-read-currently-playing"))
	results = sp.search(q='weezer', limit=20)
	return render(request, 'overview/dashboard.html')

def overview(request):
	code = request.GET.urlencode().split("=")[1]
	print(code, 'is code') # code (token) is returned
	if code:
		songs = []
		sp = spotipy.Spotify(auth=code)
		results = sp.current_user_saved_tracks()
		print(results)
		for idx, item in enumerate(results['items']):
			track = item['track']
			songs.append(track['artists'][0]['name'])
			return render(request, 'overview/dashboard.html', {'songs': songs})
	else:
		return 200

it appears I have to include the line results = sp.search(q='weezer', limit=20) or nothing happens.

Anyway, when I click allow on Spotify's popup and get to the callback, with a token, I get the following error

SpotifyException at /callback/
http status: 401, code:-1 -https://api.spotify.com/v1/me/tracks?limit=20&offset=0:
 Invalid access token, reason: None

What exactly is going wrong here? Any help would be appreciated, and apologies for the ugly code!

The variable code in def overview(request) is probably the authorization code, as described in the authorization guide, not the access token, which is what the auth parameter of Spotify expects.

More importantly, though, why are you trying to implement the authorization process yourself? spotipy already has authorization managers that do that for you: SpotifyClientCredentials, SpotifyOAuth, SpotifyPKCE, and SpotifyImplicitGrant. You're making things more complicated than they need to be. All you need to do is the following:

from spotipy import Spotify, SpotifyOAuth

spotify = Spotify(
    auth_manager=SpotifyOAuth(
        client_id="client_id",
        client_secret="client_secret",
        redirect_uri="http://localhost:8080/callback/",
        scope="user-library-read user-read-currently-playing"
    )
)

results = spotify.current_user_saved_tracks()
print(results)
songs = []
for idx, item in enumerate(results['items']):
    track = item['track']
    songs.append(track['artists'][0]['name'])

Do not create a new instance of Spotify for each request, which is what you appear to be doing; that doesn't make sense, because then you will have to go through the authorization process again.
Instead, create an instance of Spotify as a global variable and use it in each request. If you need more help, you need to post more code. It's hard for me to figure out what exactly you're trying to do, especially given the fact that the functions you posted don't call each other and I have no idea what the request parameter of the overview function is.

Thanks @Peter-Schorn! Much appreciated.

Everything you're saying makes total sense, and it now works just fine.
