为了访问我的播放列表，我使用了以下示例代码，该代码来自spotipy documentation 页面：

import pprint
import sys
import os
import subprocess

import spotipy
import spotipy.util as util


client_id = 'my_id'
client_secret = 'my_secret'
redirect_uri = 'http://localhost:8000/callback/'

scope = 'user-library-read'

if len(sys.argv) > 1:
    username = sys.argv[1]
else:
    print "Usage: %s username" % (sys.argv[0],)
    sys.exit()

token = util.prompt_for_user_token(username, scope, client_id, client_secret, redirect_uri)

if token:
    sp = spotipy.Spotify(auth=token)
    results = sp.current_user_saved_tracks()
    for item in results['items']:
        track = item['track']
        print track['name'] + ' - ' + track['artists'][0]['name']
else:
    print "Can't get token for", username

当我使用python myscript.py myusername 运行脚本时，我得到了这个：

     User authentication requires interaction with your
            web browser. Once you enter your credentials and
            give authorization, you will be redirected to
            a url.  Paste that url you were directed to to
            complete the authorization.


Opening https://accounts.spotify.com/authorize?scope=user-library-read&redirect_uri=http%3A%2F%2Flocalhost%3A8000%2Fcallback&response_type=code&client_id=d3b2f7a12362468daa393cf457185973 in your browser


Enter the URL you were redirected to:

然后，如果我输入http://localhost:8000/callback/，我会收到以下错误：

token = util.prompt_for_user_token(username, scope, client_id, client_secret, redirect_uri)
  File "/Library/Python/2.7/site-packages/spotipy/util.py", line 86, in prompt_for_user_token
    token_info = sp_oauth.get_access_token(code)
  File "/Library/Python/2.7/site-packages/spotipy/oauth2.py", line 210, in get_access_token
    raise SpotifyOauthError(response.reason)
spotipy.oauth2.SpotifyOauthError: Bad Request

我该如何解决这个问题？

我运行了相同的示例代码并遇到了相同的问题。但是通过首先在本地主机上运行服务器 python -m SimpleHTTPServer 然后使我的应用程序的网站 http://localhost:8000 和我的重定向 http://localhost:8000 也使它工作。之后我打开了一个新的终端窗口并运行python myscript.py my_user_name url 然后在我的浏览器中打开，如果它没有为你打开，你可以复制并粘贴它从终端中这一行给你的 url 链接

Opening https://accounts.spotify.com/authorize?scope=user-library-read&redirect_uri=http%3A%2F%2Flocalhost%3A8000%2Fcallback&response_type=code&client_id=d3b2f7a12362468daa393cf457185973 in your browser

直接进入您的浏览器，您会看到一个页面，要求您授予该应用访问您帐户的权限。完成此操作后，您应该在终端中复制和粘贴的新 url 将直接出现在浏览器中。之后您不会看到任何事情发生，因为您需要打印令牌：

token = util.prompt_for_user_token(
    username, scope, client_id, client_secret, redirect_uri)

if token:
  print "token: ", token
  sp = spotipy.Spotify(auth=token)
  # code 
else:
  print "Can't get token for", username
