Spotipy 授权代码流“仅有效的承载身份验证”错误

问题描述 投票：0回答：1

我正在尝试了解 Spotipy 库以创建一些供个人使用的程序。最初我尝试使用“客户端凭证流”访问 Spotify，但由于“授权代码流”似乎更适合我目前关注的用例。

我相信我已经设法实现了检查是否有缓存令牌的基本流程。如果没有任何缓存的令牌，尝试获取新令牌并缓存新令牌。

问题是当我尝试获取当前正在播放的歌曲或用户信息时，API 返回“仅支持有效的承载身份验证”错误。我知道 Spotify API 使用无效令牌或不记名令牌不具有所需范围来触发此异常。但仍然找不到问题。

My Client ID、Client Secret 和 Redirect URI 定义为环境变量。

您可以在下面找到代码及其输出。 （代码中可能有一些非 Python 风格的使用，我愿意接受任何可以提高我的 Python 技能的建议。）

代码：

我已经尝试清除缓存的代码，并向 auth_manager 添加额外的范围，但结果是一样的。

你错过了两个项目

#1 需要为

spotipy

设置环境变量 
os.environ["SPOTIPY_CLIENT_ID"] = "<your client ID>"
os.environ["SPOTIPY_CLIENT_SECRET"] = "<your client Secret>"
os.environ["SPOTIPY_REDIRECT_URI"] = "<your App's registered redirect URI>"

#2 Spotify() 类使用输入参数正确分配初始化

来自

spotipy.Spotify(auth_manager)

到

spotipy.Spotify(auth_manager=auth_manager)

你的方法

演示代码

import spotipy
from spotipy.oauth2 import SpotifyOAuth
from spotipy import cache_handler
import os
from pprint import pprint

# Set your Spotify API credentials as environment variables, it will pick by spotipy API
os.environ["SPOTIPY_CLIENT_ID"] = "<your client ID>"
os.environ["SPOTIPY_CLIENT_SECRET"] = "<your client Secret>"
os.environ["SPOTIPY_REDIRECT_URI"] = "<your App's registered redirect URI>"

# multiple scopes
oAuthscope = "user-read-email,user-read-private,user-library-read,user-read-playback-state,user-modify-playback-state,user-read-currently-playing"

Sp_Cache = cache_handler.CacheFileHandler()
auth_manager = spotipy.SpotifyOAuth(scope=oAuthscope,cache_handler=Sp_Cache)
Sp_oAuth  = spotipy.Spotify(auth_manager=auth_manager)

def init_Spotify_Session():
    access_token = ""
    print ("\n Access_Token variable defined!")
    Token_Data = Sp_Cache.get_cached_token()
    if Token_Data is not None:
        print ("\n Cached Token = \n")
        pprint (Token_Data )
        print ("\n")
    else :
        print ("There is no cached token!!! Token cannot be printed!!")

    if not Token_Data:
        print ("There is not any cached token!")

        authorisation_url = auth_manager.get_authorize_url()
        print ("\n Authorisation URL retrieved = " + authorisation_url)
        print ("\n Trying to get authorisation response:")

        oAuth_Response = auth_manager.get_auth_response()
        print ("\n oAuthResponse= ")
        print (type(oAuth_Response))
        print("\n oAuth_Response = " + oAuth_Response + "\n")

        print ("\n Trying to get new access token!!! \n")
        Token_Data = auth_manager.get_access_token(code=oAuth_Response)
        access_token = Token_Data["access_token"]
        print ("\n Access Token = \n")
        pprint (Token_Data)
        pprint (access_token)

        Sp_Cache.save_token_to_cache(Token_Data)

        print("\n Cached New Token = ")
        print(Sp_Cache.get_cached_token()),print ("\n")

def Get_Current_Song():
    response_current_track = Sp_oAuth.current_user_playing_track()
    if response_current_track  is not None and response_current_track["item"] is not None:
        song = response_current_track["item"]
        print(song['artists'][0]['name'], " – ", song['name'])

init_Spotify_Session()

Get_Current_Song()

结果

简单的方法

你也不需要自己处理令牌。

spotipy
适合你。 如果不存在
.cache
，将启动浏览器并登录
spotify
以获取令牌。

如果退出'.cache

, then skip login and pick up the token from
.cache`文件。

.cache
将包括六个信息 (
access_token
, 
token_type
, 
expires_in
, 
refresh_token
, 
scope
和 
expires_at
)

这个简单的代码

import spotipy
from spotipy.oauth2 import SpotifyOAuth
import os

# Set your Spotify API credentials as environment variables, it will pick by spotipy API
os.environ["SPOTIPY_CLIENT_ID"] = "<your client ID>"
os.environ["SPOTIPY_CLIENT_SECRET"] = "<your client Secret>"
os.environ["SPOTIPY_REDIRECT_URI"] = "<your App's registered redirect URI>"

# multiple scopes
oAuthscope = "user-read-email,user-read-private,user-library-read,user-read-playback-state,user-modify-playback-state,user-read-currently-playing"

Sp_oAuth = spotipy.Spotify(auth_manager=SpotifyOAuth(scope=oAuthscope))

def Get_Current_Song():
    response_current_track = Sp_oAuth.current_user_playing_track()
    if response_current_track  is not None and response_current_track["item"] is not None:
        song = response_current_track["item"]
        print(song['artists'][0]['name'], " – ", song['name'])

Get_Current_Song()

结果
