授权码流

Question

我正在使用Spotipy python库与Spotify web api进行交互。我已经研究过API和文档，但我没有看到一个清晰的示例来显示该库如何支持授权代码流(https://developer . Spotify . com/we b-API/Authorization-guide/# Authorization-code-flow)。

Answer 1

当我试图这样做时，不幸的是，这些答案都没有真正让我到达那里。当我最终弄清楚它时，我在这篇文章中详细介绍了如何：https://stackoverflow.com/a/42443878/2963703 我使用Django作为我的后端，但所有spotify api oauth的东西都是用javascript完成的，所以它应该对你非常有用。

Answer 2

如果有人需要工作代码，这里是我的当前代码。

只要记得修改client_id等就可以了。我把它们放在config.py中。

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)

Answer 3

我在Spotipy的帮助下实现了一个简单的授权代码流。也许这对其他人也有帮助。同样在github上:https://github.com/perelin/spotipy_oauth_demo

代码如下：

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)
