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
