DRF笔记

一、CBV与FBV

• FBV（Function-Based Views）

# views.py
from django.shortcuts import  HttpResponse
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def book_views(request):
    if request.method == "GET":
        return HttpResponse("这是get")
    if request.method == "POST":
        return HttpResponse("这是post")
    if request.method == "DELETE":
        return HttpResponse("这是delete")
    if request.method == "PUT":
        return HttpResponse("这是put")

# urls.py
from django.urls import path
from app001 import views
urlpatterns = [
    # fbv
    path('book/',views.book_views),
]

• CBV（Class-Based Views）

# views.py
from django.shortcuts import  HttpResponse
from django.views import View
from django.utils.decorators import method_decorator


@method_decorator(csrf_exempt, name='dispatch')  # 类视图禁止crsf
class BookView(View):
    def get(self, request):
        return HttpResponse("这是get")

    def post(self, request):
        return HttpResponse("这是post")

    def delete(self, request):
        return HttpResponse("这是delete")

    def put(self, request):
        return HttpResponse("这是put")

# urls.py
from django.urls import path
from app001 import views
urlpatterns = [
     # cbv
    path('book/',views.BookView.as_view())
]

• 注意

  1 urls.py 中使用book/访问时需要加上/,否则会转为get请求
  2 访问get外的其它请求，需要禁用csrf，cbv与fbv禁用方法是不一样的
