FBV 基于函数的视图 (function base views)
CBV 基于类的视图 (class base views)
也就是说我们是用函数编写视图~还是类编写视图我们来看下两个的简单实现
urlpatterns = [
path(‘admin/‘, admin.site.urls),
path(‘test_fbv‘, test_fbv), #FBV
path(‘test_cbv‘, TestCBV.as_view()) #CBV]
def test_fbv(request): ##函数式视图
return HttpResponse(“ok”)
class TestCBV(View): ##类式视图
def get(self, request):
return HttpResponse(“ok”)
CBV会执行as_view()方法,
a. 接口开发
urlpatterns = [
# url(r'^admin/', admin.site.urls),
url(r'^get_order/', views.get_order),
url(r'^add_order/', views.add_order),
url(r'^del_order/', views.del_order),
url(r'^update_order/', views.update_order),
]
def get_order(request):
return HttpResponse('')
def add_order(request):
return HttpResponse('')
def del_order(request):
return HttpResponse('')
def update_order(request):
return HttpResponse('')
b. restful 规范(建议)
1. 根据method不同做不同的操作,示例:
基于FBV:
urlpatterns = [
url(r'^order/', views.order),
]
def order(request):
if request.method == 'GET':
return HttpResponse('获取订单')
elif request.method == 'POST':
return HttpResponse('创建订单')
elif request.method == 'PUT':
return HttpResponse('更新订单')
elif request.method == 'DELETE':
return HttpResponse('删除订单')
基于CBV:
urlpatterns = [
url(r'^order/', views.OrderView.as_view()),
]
class OrderView(View):
def get(self,request,*args,**kwargs):
return HttpResponse('获取订单')
def post(self,request,*args,**kwargs):
return HttpResponse('创建订单')
def put(self,request,*args,**kwargs):
return HttpResponse('更新订单')
def delete(self,request,*args,**kwargs):
return HttpResponse('删除订单')
