假設(shè)訪問的views.py如下

1.使用url配置默認頁

from django.conf.urls import urlfrom django.contrib import adminfrom django.urls import pathfrom HelloWorld import viewsurlpatterns = [ path(’admin/’, admin.site.urls), url(’^$’, views.hello),]

這樣可以訪問http://127.0.0.1:8090/

2.使用path配置默認頁

from django.contrib import adminfrom django.urls import pathfrom HelloWorld import viewsurlpatterns = [ path(’admin/’, admin.site.urls), # url(’^$’, views.hello), path(’’, views.hello),]

這樣也可以訪問http://127.0.0.1:8090/

3.使用path配置hello頁

from django.contrib import adminfrom django.urls import pathfrom HelloWorld import viewsurlpatterns = [ path(’admin/’, admin.site.urls), # url(’^$’, views.hello), # path(’’, views.hello), path(’hello/’, views.hello),]

這樣可以訪問http://127.0.0.1:8090/hello/

4.使用url和正則

from django.conf.urls import urlfrom django.contrib import adminfrom django.urls import pathfrom HelloWorld import viewsurlpatterns = [ path(’admin/’, admin.site.urls), # url(’^$’, views.hello), # path(’’, views.hello), # path(’hello/’, views.hello), url(’^hello’, views.hello),]

可以訪問http://127.0.0.1:8090/hello+任意字符

5.如果有多個app，還可以使用include

from django.contrib import adminfrom django.urls import path, includefrom CRUD import viewsurlpatterns = [ path(’admin/’, admin.site.urls), path(’’, views.login_html), path(’login.html/’, views.login_html), path(’index.html/’, views.index_html), path(’debug.html/’, views.debug_html), path(’debug/’, views.debug), path(’login/’, views.login), path(’one/’, include(’Model.urls’)), path(’two/’, include(’Model2.urls’)), path(’three/’, include(’Model3.urls’)), path(’four/’, include(’Model4.urls’)),]
