局部避免crsf的方式

针对视图函数：

from django.views.decorators.csrf import csrf_exempt@csrf_exempt def foo(request):    return HttpResponse("foo")

针对CBV：

# 方式1  在类上方使用@method_decorator(csrf_exempt,name="dispatch")class IndexView(View):    # 方式2  在类的 dispatch 方法上使用 @csrf_exempt    @method_decorator(csrf_exempt)    def dispatch(self, request, *args, **kwargs):    print("hello world")    # 执行父类的dispatch方法                                res=super(IndexView,self).dispatch(request, *args, **kwargs)        print("hello boy")        return res

在url中配置：

from django.views.decorators.csrf import csrf_exempturlpatterns = [    url(r'^myview/$', csrf_exempt(views.MyView.as_view()), name='myview'),]

 rest_framework的简单示例

 

以books为例：(1)创建表，数据迁移(2)创建表序列化类BookSerializerclass BookSerializer(serializers.HyperlinkedModelSerializer):	class Meta:		model=Book		fields="__all__" (3)创建视图类：  class BookViewSet(viewsets.ModelViewSet):		queryset = Book.objects.all()		serializer_class = BookSerializer(4) 设计url： router.register(r'books', views.BookViewSet)

APIview

from rest_framework.views import APIViewclass APIView(View):        def as_view():             view = super(APIView, cls).as_view(**initkwargs)  #  self.dispatch            def dispatch():         # 重新封装request         request = self.initialize_request(request, *args, **kwargs)         self.request = request                 # 初始化操作        self.initial(request, *args, **kwargs)                    if request.method.lower() in self.http_method_names: 　　　　　　　# http_method_names = ['get', 'post', 'put', 'patch', 'delete', 'head', 'options', 'trace']            handler = getattr(self, request.method.lower(),self.http_method_not_allowed)  　　　　　　　# handler=self.get            response = handler(request, *args, **kwargs)   # self.get(request, *args, **kwargs)                                            1 CBV :    as_view    dispatch    2 掌握API源码流程：    as_view    dispatch3 serializers组件
