spotipy authorization code flow

问题:

I am using the Spotipy python library to interact with the Spotify web api. I have worked through the API and docs but I do not see a clear example that shows how the library supports the Authorization code flow ( https://developer.spotify.com/web-api/authorization-guide/#authorization-code-flow ).

I implemented a simple Authorization Code flow with the help of Spotipy. Maybe this is helpful for other people as well. Also on github: https://github.com/perelin/spotipy_oauth_demo

Here is the code:

from bottle import route, run, request
import spotipy
from spotipy import oauth2

PORT_NUMBER = 8080
SPOTIPY_CLIENT_ID = 'your_client_id'
SPOTIPY_CLIENT_SECRET = 'your_client_secret'
SPOTIPY_REDIRECT_URI = 'http://localhost:8080'
SCOPE = 'user-library-read'
CACHE = '.spotipyoauthcache'

sp_oauth = oauth2.SpotifyOAuth( SPOTIPY_CLIENT_ID, SPOTIPY_CLIENT_SECRET,SPOTIPY_REDIRECT_URI,scope=SCOPE,cache_path=CACHE )

@route('/')
def index():

    access_token = ""

    token_info = sp_oauth.get_cached_token()

    if token_info:
        print "Found cached token!"
        access_token = token_info['access_token']
    else:
        url = request.url
        code = sp_oauth.parse_response_code(url)
        if code:
            print "Found Spotify auth code in Request URL! Trying to get valid access token..."
            token_info = sp_oauth.get_access_token(code)
            access_token = token_info['access_token']

    if access_token:
        print "Access token available! Trying to get user information..."
        sp = spotipy.Spotify(access_token)
        results = sp.current_user()
        return results

    else:
        return htmlForLoginButton()

def htmlForLoginButton():
    auth_url = getSPOauthURI()
    htmlLoginButton = "<a href='" + auth_url + "'>Login to Spotify</a>"
    return htmlLoginButton

def getSPOauthURI():
    auth_url = sp_oauth.get_authorize_url()
    return auth_url

run(host='', port=8080)

If someone needs the working code here is my current.

Just remember to change the client_id, etc. I put them in config.py.

import spotipy
import spotipy.util as util
from config import CLIENT_ID, CLIENT_SECRET, PLAY_LIST, USER
import random

token = util.oauth2.SpotifyClientCredentials(client_id=CLIENT_ID, client_secret=CLIENT_SECRET)

cache_token = token.get_access_token()
spotify = spotipy.Spotify(cache_token)

results1 = spotify.user_playlist_tracks(USER, PLAY_LIST, limit=100, offset=0)

The Spotipy library supports the Authorization Code flow, as documented here. For more information, you could also check out Spotipy's oAuth2 module and Util module.

When I was trying to do this none of these answers really got me there unfortunately. When I ended up figuring it out I detailed how in this post: https://stackoverflow.com/a/42443878/2963703 I was using Django as my backend but all the spotify api oauth stuff is done in javascript so it should still be very useful for you.
