Question

我有一个Flask应用程序可以与以下views开头一起使用：

@app.route('/login', methods=['GET', 'POST'])
def do_admin_login():

    if request.form['username'] != None:
        session['logged_in'] = True
    return redirect(url_for('index'))

然后：

@app.route("/index")
def index():     
    #Auth Step 1: Authorization
    url_args = "&".join(["{}={}".format(key,urllib.quote(val)) for key,val in auth_query_parameters.iteritems()])
    auth_url = "{}/?{}".format(SPOTIFY_AUTH_URL, url_args)

    return redirect(auth_url)

然后：

@app.route("/callback/q")
def callback():
    (long callback here)
    sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)
    print "Getting user playlists..."
    playlist = get_user_playlist(USERNAME, sp)
    print "Getting playlists contents..."
    for i, p in enumerate(playlist):
      get_playlist_content(USERNAME, p, sp)
      print "Getting playlist # {} audio features...".format(i)
      get_playlist_audio_features(USERNAME, p, sp)
      print "Sorting..."

    return redirect(url_for('homepage'))

最终应将应用引导至：

@app.route('/')
def homepage():

    if not session.get('logged_in'):
        return render_template('login.html')
    else:        
        return render_template('homepage.html')

使用python app.py来运行它就像是一种魅力，但是如果我使用 gunicorn 来运行，如下所示，

gunicorn -c gconfig.py app：app --log-level = debug

在终端上，我看到该应用程序经过login()，index()，callback()，但是在login页面上停了下来，现在重新加载了空白表格，好像没有{ {1}}。

终端输出：

session['logged_in']

我不能在这里问什么。有人可以指出我正确的方向吗？
