urls.py中urlpatterns与正则表达式使用的配置

# 第一种 from django.conf.urls import url 与url 匹配

from django.contrib import admin
# from django.urls import path
from django.conf.urls import url
from app02 import views

urlpatterns = [
    url('admin/', admin.site.urls),
    url('index/', views.index),
    url(r'home/[0-9]{4}/', views.home), # 可添加正则表达式函数
    url('login/',views.login),
    url('register/',views.register),
    url('userlist/',views.userlist),
    url('edit_user/',views.edit_user),
    url('delete_user/',views.delete_user),
]

# 第二种 from django.urls import path 与 path 匹配
# 正则表达式在此处无效

from django.contrib import admin
from django.urls import path
# from django.conf.urls import url
from app02 import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', views.index),
    path('home/', views.home),
    path('login/',views.login),
    path('register/',views.register),
    path('userlist/',views.userlist),
    path('edit_user/',views.edit_user),
    path('delete_user/',views.delete_user),
]

 

# 如果需要在path模式下使用正则,则应该导入re_path


from django.contrib import admin
from django.urls import path,re_path
# from django.conf.urls import url
from app02 import views

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path('index/', views.index),
    re_path(r'home/[0-9]{4}/', views.home),
    re_path('login/',views.login),
    re_path('register/',views.register),
    re_path('userlist/',views.userlist),
    re_path('edit_user/',views.edit_user),
    re_path('delete_user/',views.delete_user),
]
