下面是以上URLconf 使用命名组的重写：复制代码from django.conf.urls import urlfrom . import viewsurlpatterns = [    url(r'^articles/2003/$', views.special_case_2003),    url(r'^articles/(?P
      
       [0-9]{4})/$', views.year_archive),    url(r'^articles/(?P
       
        [0-9]{4})/(?P
        
         [0-9]{2})/$', views.month_archive),    url(r'^articles/(?P
         
          [0-9]{4})/(?P
          
           [0-9]{2})/(?P
           
            [0-9]{2})/$', views.article_detail),]复制代码
           
          
         
        
       
      

视图函数中指定默认值复制代码# urls.py中from django.conf.urls import urlfrom . import viewsurlpatterns = [    url(r'^blog/$', views.page),    url(r'^blog/page(?P
       
        [0-9]+)/$', views.page),]# views.py中，可以为num指定默认值def page(request, num="1"):    pass
       

 

 

正则表示式 from django.conf.urls import urlfrom . import viewsurlpatterns = [    url(r'^articles/2003/$', views.special_case_2003),    url(r'^articles/([0-9]{4})/$', views.year_archive),    url(r'^articles/([0-9]{4})/([0-9]{2})/$', views.month_archive),    url(r'^articles/([0-9]{4})/([0-9]{2})/([0-9]+)/$', views.article_detail),]
