OAuthException：在使用Gunicorn和Flask時沒有可用的令牌

Question

我一直在開發一個本地小型網站，它使用Facebook作爲主要登錄方法，並且完美地工作。然而，當我使用Gunicorn部署到我的數字海洋滴我得到這個錯誤：

[2015-05-05 09:15:15 +0000] [1561] [ERROR] Error handling request

這是我的代碼處理登錄：

@app.route('/login') 
def login(): 
    if not session.get('logged_in'): 
     return facebook.authorize(callback=url_for('authorized', next=request.args.get('next') or request.referrer or None, _external=True)) 
    return redirect(url_for('feed')) 

@app.route('/login/authorized') 
@facebook.authorized_handler 
def authorized(resp): 
    if resp is None: 
     return 'Access denied: reason=%s error=%s' % (request.args['error_reason'], request.args['error_description']) 
    me = facebook.get('/me') 
    picture = facebook.get('/me/picture?redirect=0&height=200&width=200&type=normal&fields=url,width,height') 
    session['oauth_token'] = (resp['access_token'], '') 
    session['logged_in'] = True 
    session['picture'] = picture.data['data']['url'] 
    g.db.cursor.execute('select fb_id from user where fb_id=%s', [me.data['id']]) 
    data = g.db.cursor.fetchone() 
    if data is None: 
     g.db.cursor.execute('insert into user (fb_id, first_name, last_name, picture) values (%s, %s, %s, %s)', [me.data['id'], me.data['first_name'], me.data['last_name'], picture.data['data']['url']]) 
     g.db.commit() 
     g.db.cursor.execute('select user_id from user where fb_id=%s', [me.data['id']]) 
     result = g.db.cursor.fetchone() 
     session['id'] = result[0] 
     flash('You\'re logged in!') 
     return redirect(url_for('feed')) 
    g.db.cursor.execute('select user_id from user where fb_id=%s', [me.data['id']]) 
    result = g.db.cursor.fetchone() 
    session['id'] = result[0] 
    flash('You have succesfully logged in') 
    return redirect(url_for('feed')) 

@facebook.tokengetter 
def get_facebook_oauth_token(): 
    return session.get('oauth_token') 

我一直在谷歌搜索和谷歌上搜索答案，但我似乎無法找到像這樣的東西。任何指針都將:-)理解

編輯： 想通我的nginx的conf可能是很好的瞭解，以及：

server { 
    listen 80; 

    server_name localhost; 
    client_max_body_size 2M; 

    access_log /var/log/nginx/access.log; 
    error_log /var/log/nginx/error.log; 

    location/{ 
     proxy_pass   http://127.0.0.1:8000/; 
     proxy_redirect  default; 

     proxy_set_header Host    $host; 
     proxy_set_header X-Real-IP  $remote_addr; 
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    } 
}

原來，從Facebook請求數據之前請求訪問令牌解決問題。所以我的授權方法應該是這樣的：

@app.route('/login/authorized') 
@facebook.authorized_handler 
def authorized(resp): 
    if resp is None: 
     return 'Access denied: reason=%s error=%s' % (request.args['error_reason'], request.args['error_description']) 
    session['oauth_token'] = (resp['access_token'], '') 
    me = facebook.get('/me') 
    picture = facebook.get('/me/picture?redirect=0&height=200&width=200&type=normal&fields=url,width,height') 
    session['logged_in'] = True 
    session['picture'] = picture.data['data']['url'] 
    g.db.cursor.execute('select fb_id from user where fb_id=%s', [me.data['id']]) 
    data = g.db.cursor.fetchone() 
    if data is None: 
     g.db.cursor.execute('insert into user (fb_id, first_name, last_name, picture) values (%s, %s, %s, %s)', [me.data['id'], me.data['first_name'], me.data['last_name'], picture.data['data']['url']]) 
     g.db.commit() 
     g.db.cursor.execute('select user_id from user where fb_id=%s', [me.data['id']]) 
     result = g.db.cursor.fetchone() 
     session['id'] = result[0] 
     flash('You\'re logged in!') 
     return redirect(url_for('feed')) 
    g.db.cursor.execute('select user_id from user where fb_id=%s', [me.data['id']]) 
    result = g.db.cursor.fetchone() 
    session['id'] = result[0] 
    flash('You have succesfully logged in') 
    return redirect(url_for('feed')) 

希望能幫助別人:-)
