第四单元 路由层

路由分为两种一种是静态路由和动态路由 1. 静态路由 path方法

from myapp import views
urlpatterns = [
	path('index/', views.Index.as_view())
]

re_path方法

from from django.urls import path, re_path
urlpatterns = [
	# 正则路由
	re_path(r'^[a-z]{5}/$', views.Index.as_view())
]

2.动态路由 int:id方法(可以在视图传参)

在views文件中

from django.views import View
class Index(View):
	def get(self, request, id):
		return HttpResponse(f'传来的参数为{id}')

在urls文件中

from myapp import views
urlpatterns = [
	path('index//', views.Index.as_view())
]

3.路由分发

在主路由的url.py中

from django.urls import path,include
urlpatterns = [
	path('', include(urls))
]

在子应用中创建urls.py文件用来写路由

# 导入需要配置路由的模块
from django.urls import path,re_path
from books import views

# 子路由
urlpatterns = [
    path('register/',views.RegisterView.as_view()),
    path('login/',views.LoginView.as_view()),
    path('index/',views.IndexView.as_view()),
    # cookie
    path('cookie/',views.CookView.as_view()),
    path('delcookieview/',views.DelCookieView.as_view())
]
