爲什麼我的重定向中間件失敗？

Question

我有一個將移動用戶重定向到移動網站的中間件，但是如果URL是/property/，我想引導他們訪問整個站點。移動重定向正在工作，但不排除/property/。

這是當前的中間件。

       test = user_agent[0:4].lower() 
       if test in user_agents_test: 
        is_mobile = True 

     return is_mobile 

settings.py中我有這樣的：

MOBILE_SITE_URL = 'http://mobile.somesite.com/' 
NON_MOBILE_REDIRECT_URLS = ['/property/'] 

Answer 1

它可能沒有足夠的，只是爲了避免給定的URL重定向到mobile.。如果用戶已經來自mobile.somesite.com/..../，則需要將他們主動重定向到www.以遠離移動站點。

這是未經測試，但應該是八九不離十：

class MobileRedirectMiddleware(object): 
    """ 
    Redirects mobile users to a different site. 
    """ 
    def process_request(self, request): 
     was_mobile = settings.MOBILE_SITE_URL in request.META.HTTP_REFERER 
     NON_MOBILE_REDIRECT_URLS = getattr(settings, 'NON_MOBILE_REDIRECT_URLS', []) 

     if request.path in NON_MOBILE_REDIRECT_URLS and was_mobile: 
      # redirect them to 'www.somesite.com/.../' 
      return HttpResponseRedirect(settings.MAIN_SITE_URL + request.path.lstrip('/')) 

     if self._is_mobile(request): 
      return HttpResponseRedirect(settings.MOBILE_SITE_URL) 

    def _is_mobile(self, request): 
     is_mobile = False 

     # no longer need to check urls in here 

     if request.META.has_key('HTTP_USER_AGENT'): 
      ...
