我可以使用我的 Spotify 帐户登录，但在同意连接时遇到“访问本地主机被拒绝您无权查看此页面。 HTTP 错误 403"

尝试创建新应用程序，更改浏览器（从 chrome 到 safari），清除 cookie。我还使用了不带spotipy的spotify的api并且它有效（艺术家的前10首曲目），如果这个信息有任何帮助的话。

Spotipy 是 Spotify Web API 的 Python 库，通过抽象化管理身份验证流程、令牌和令牌刷新所涉及的大部分复杂性，简化了 OAuth2 身份验证的处理。

Spotipy 的内置 OAuth 流程减少了手动回调处理和代码解码的需求，这通常在其他环境中出现，例如将 Express 与 Node.js 结合使用：

演示

demo.py

import spotipy
from flask import Flask, redirect, session, url_for
from spotipy.oauth2 import SpotifyOAuth
from spotipy import cache_handler
import os

app = Flask(__name__)

# Set your Spotify API credentials as environment variables, it will pick by spotipy API
client_id = os.getenv("CLIENT_ID")
if client_id is not None:
    os.environ["SPOTIPY_CLIENT_ID"] = client_id
else:
    print("CLIENT_ID environment variable is not set.")

client_secret = os.getenv("CLIENT_SECRET")
if client_secret is not None:
    os.environ["SPOTIPY_CLIENT_SECRET"] = client_secret
else:
    print("CLIENT_SECRET environment variable is not set.")

# Set your redirect URI
os.environ["SPOTIPY_REDIRECT_URI"] = "http://localhost:3000/callback"

# Define the required OAuth scope
oAuthscope = "playlist-read-private"

# Initialize the cache handler and auth manager for Spotipy
Sp_Cache = cache_handler.CacheFileHandler()
auth_manager = spotipy.SpotifyOAuth(scope=oAuthscope, cache_handler=Sp_Cache)
sp_oauth = spotipy.Spotify(auth_manager=auth_manager)

# Ensure the Flask application has a secret key for secure sessions
app.secret_key = os.urandom(24)

@app.route('/')
def home():
    return redirect(url_for('get_playlists'))

@app.route('/get_playlists')
def get_playlists():
    playlists = sp_oauth.current_user_playlists()
    playlists_info = [(pl['name'], pl['external_urls']['spotify']) for pl in playlists['items']]
    playlists_html = '<br>'.join([f'{name}: {url}' for name, url in playlists_info])
    return playlists_html

@app.route('/logout')
def logout():
    # Clearing the Flask session for logging out
    session.clear()
    return redirect(url_for('home'))

# run flask app when file is run
if __name__ == '__main__':
    app.run(debug=True)

结果
