DRF

views.py：

from rest_framework.viewsets import GenericViewSet
from rest_framework import serializers
from rest_framework.pagination import PageNumberPagination
from drf import models
from rest_framework.response import Response


class PagerSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Role
        fields = "__all__"


class TestView(GenericViewSet):
    # 看源码
    queryset = models.Role.objects.all()  # 数据
    serializer_class = PagerSerializer  # 序列化
    pagination_class = PageNumberPagination  # 分页

    def list(self, request, *args, **kwargs):
        # 获取数据
        roles = self.get_queryset()
        # 分页
        role_page = self.paginate_queryset(roles)
        # 序列化
        ser = self.get_serializer(instance=role_page, many=True)
        return Response(ser.data)

urls.py：

from django.urls import re_path, include
from drf import views
from rest_framework import routers
from django.conf.urls import url

router = routers.DefaultRouter()
router.register("aaaaa", views.TestView)
router.register("bbbbb", views.TestView)

urlpatterns = [
    re_path('view/$', views.TestView.as_view({"get": "list"})),
    url(r'^', include(router.urls)),  # 这里需要用 url
]

最先的视图需要用 re_path 匹配，不能用 path

访问一个不存在的路径

都加了前缀
