瓶端點問題 - 裝飾登錄檢查

我發現了一個問題瓶端點問題 - 裝飾登錄檢查

BuildError: Could not build url for endpoint 'home'. Did you mean 'Welcome' instead?

歡迎的另一個功能在應用程序（第一個函數定義）

def loginRequired(func): 
    def wrapper(): 
     access_token = session.get('access_token') 
     if access_token is None: 
      return redirect(url_for('login')) 
     else: 
      return func 

    return wrapper 
@app.route('/Homepage') 
@loginRequired 
def home():  
    return render_template('Homepage.html', title="Title") 

@app.route('/login') 
def login(): 
    callback = url_for('authorized', _external=True) 
    return google.authorize(callback=callback) 


@app.route(REDIRECT_URI) 
@google.authorized_handler 
def authorized(resp): 
    access_token = resp['access_token'] 
    session['access_token'] = access_token, '' 
    return redirect(url_for('home')) 


@google.tokengetter 
def get_access_token(): 
    return session.get('access_token')

谷歌正在做好的跡象（被提示），但我似乎無法得到重定向工作家。如果我回家更改爲另一個功能（即isent需要登錄），然後重定向工作

另外，如果我把線

access_token = session.get('access_token') 
if access_token is None: 
    return redirect(url_for('login'))

家庭功能內，不包括裝飾它的工作原理

思考？

你可以發佈跟蹤回錯誤信息嗎？ –

感謝您的回覆。 Traceback在這裏http://pastebin.com/wZS0s6Xm – bpb101

找到了解決方案

我跟着Flasks文檔，發現這個登錄裝飾。這工作。看來你使用functools.wraps()來處理這個給你。 http://flask.pocoo.org/docs/0.12/patterns/viewdecorators/

from functools import wraps 
    from flask import g, request, redirect, url_for 

    def login_required(f): 
    @wraps(f) 
    def decorated_function(*args, **kwargs): 
     access_token = session.get('access_token') 
     if access_token is None: 
      return redirect(url_for('login', next=request.url)) 
     return f(*args, **kwargs) 
    return decorated_function
