关键的在于urls.py，在配置视图函数时配置了两个url。

views.py 代码

 1 from django.shortcuts import render,HttpResponse,redirect,reverse 2  3 books_list = [ 4 ‘自是人生长恨水长东‘, 5 ‘可堪孤馆闭春寒‘, 6 ‘雾失楼台，月迷津渡‘, 7 ‘楼高不见章台路‘ 8 ] 9 def books(request,page=0):10 return HttpResponse(books_list[page])

urls.py 代码

1 from django.urls import path2 from booktest import views3 4 urlpatterns = [5 # path(‘^article/$‘, views.article),6 path(‘books‘, views.books),7 path(‘books/<int:page>‘, views.books)8 ]
