Original GitHub issue: https://github.com/spotipy-dev/spotipy/issues/815

I am using Spotipy in a Django application, and it was working fine for some time (likely the token age time) but now it is trying to spin up a development server on 120.0.0.1:8090 (as mentioned in app.py example), which is where Django is running. lsof indeed shows multiple listeners on that port:

➜  ~ lsof -i:8090
COMMAND     PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
Google    29820 anonnn   45u  IPv4 0x93a23e6b2bffd7d3      0t0  TCP localhost:52408->localhost:irdmi (ESTABLISHED)
Python    31091 anonnn    4u  IPv4 0x93a23e6b2e0b8d33      0t0  TCP localhost:irdmi (LISTEN)
Python    31091 anonnn    5u  IPv4 0x93a23e6b304d8293      0t0  TCP localhost:irdmi->localhost:52408 (ESTABLISHED)

This also happens when using port 8000 and 5000. How can I prevent the library from trying to spin up a server on the same port as Django?

Django Code / view functions

# spotify redirect url
def profile(request):
    # create django user here, and auth them
    cache_handler = spotipy.cache_handler.DjangoSessionCacheHandler(request)
    sp = spotipy.Spotify(auth_manager=SpotifyOAuth(scope='user-top-read',  cache_handler=cache_handler))

    playlists = sp.current_user_playlists()
    return render(request, 'accounts/profile.html', {'playlists': playlists['items']})

def login(request):
    return render(request, 'accounts/login.html')

def spotify_login(request):
    # sp = spotipy.Spotify(auth_manager=SpotifyOAuth())
    cache_handler = spotipy.cache_handler.DjangoSessionCacheHandler(request)
    auth_manager = SpotifyOAuth(scope='user-top-read',
                                                cache_handler=cache_handler, 
                                                show_dialog=True)
    return redirect(auth_manager.get_authorize_url())

Apologies if I am missing something. Thank you.

Looking at the stack trace, if get_access_token() is not manually called with the code from the callback query params, spotipy will attempt to spin up the server for you. Here is the complete working code in a Django context:

def login(request):
    return render(request, 'accounts/login.html')

# spotify redirect url
def callback(request):
    # todo: create django user here, and auth them
    cache_handler = spotipy.cache_handler.DjangoSessionCacheHandler(request)
    auth_manager = SpotifyOAuth(scope='user-top-read',
                                                cache_handler=cache_handler, 
                                                show_dialog=True)
    auth_manager.get_access_token(request.GET["code"])
    return redirect('/accounts/profile')


def profile(request):
    scope = 'user-top-read'   
    cache_handler = spotipy.cache_handler.DjangoSessionCacheHandler(request)
    sp = spotipy.Spotify(auth_manager=SpotifyOAuth(scope=scope, show_dialog=False, cache_handler=cache_handler))
    playlists = sp.current_user_playlists()
    
    return render(request, 'accounts/profile.html', {'playlists': playlists['items']} )

def spotify_login(request):
    cache_handler = spotipy.cache_handler.DjangoSessionCacheHandler(request)
    auth_manager = SpotifyOAuth(scope='user-top-read',
                                                cache_handler=cache_handler, 
                                                show_dialog=True)
    return redirect(auth_manager.get_authorize_url())
