django如何與醜陋的網址一起工作

在Django中，使用美麗的網址更容易。非常感謝！但是我用純php編寫了一個網站，現在我想遷移到Python和Django，並且仍然想讓我的醜陋的Url活着。（醜> 404）django如何與醜陋的網址一起工作

這裏是我的urls.py：

urlpatterns = [ 
     url(r'^\?user=(\d+)/$', user), 
]

而且我views.py：

def user(request, offset): 
     try: 
       offset = int(offset) 
     except ValueError: 
       raise Http404() 
     ret = 'hello user ' + str(offset) 
     return HttpResponse(ret)

但我運行服務器時出現此錯誤（其他頁面正常工作）：

Performing system checks...

有人可以幫我解決這個問題嗎？任何教程或網址是欣賞。

'？user = 12' chars after to'？ '是參數。 –

但它說：「？^用戶=（\ d +）/ $」不是一個有效的正則表達式有正則表達式 –

「沒有重複」的問題表明了一個問題「？」。你確定你在你的實際代碼中逃脫了嗎？ – Selcuk

正如Avinash在評論中所說，?之後的任何內容都是GET參數，它不是URL的一部分。你URLPATTERN應該是：

url(r'^$', user),

，你應該得到的參數與request.GET['user']你的看法。
