    path ( ' ADMIN / ' , admin.site.urls), 
    path ( ' app01 / ' , the include (( ' app01.urls ' , ' app01 ' ), namespace = ' app01 ' )),   # the first parameter is used here to include two ancestral element values, the second value of APP_NAME 
]

urls.py

from django.conf.urls Import URL
 from app01 Import views 

the urlpatterns = [ 
    URL (R & lt ' ^ Home / ' , views.Home.as_view ()), # as_view specified call as_view view of this method of fixing wording 
]

app01/urls.py

from django.shortcuts Import HttpResponse 

from django.views Import View
 class Home (View):
     '' ' must inherit the parent view when using the CBV ' '' 
    DEF dispatch (Self, Request, * args, ** kwargs):
         # call dispatch parent class 
        result = Super (Home, Self) .dispatch (Request, * args, ** kwargs)
         # using active result inherited parent view, and then return dispath can override the parent class 
        return result
     # here use get sent a request will call the get method, using the post to send the request will call the post method 
    DEF get (Self, request):
         Print (request.method)
         return HttpResponse('get')

    def post(self,request):
        print(request.method,'POST')
        return HttpResponse('post')
