from rest_framework.views import APIView

class Test(APIView):

    def get(self, request, *args, **kwargs):
        return Response('drf get ok')

DRF請求生命週期

1) 請求走的是APIView的as_view函式
2) 在APIView的as_view呼叫父類(django原生)的as_view, 還禁用了csrf認證
3) 在父類的as_view中dispatch方法請求走的又是APIView的dispatch
4) 完成任務方法交給檢視類的請求函式處理, 得到請求的響應結果, 返回給前臺

APIView(as_view())禁用csrf => View(as_view()) => APIView(dispatch()) => 檢視類的請求方法 => 響應
