第十六节 URL映射的时候指定默认参数

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 path
2 from booktest import views
3 
4 urlpatterns = [
5     # path(‘^article/$‘, views.article),
6     path(‘books‘, views.books),
7     path(‘books/<int:page>‘, views.books)
8 ]
