总路由

python"># urls.py
"""BBS1 URL ConfigurationThe `urlpatterns` list routes URLs to views. For more information please see:https://docs.djangoproject.com/en/3.2/topics/http/urls/
Examples:
Function views1. Add an import:  from my_app import views2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views1. Add an import:  from other_app.views import Home2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf1. Import the include() function: from django.urls import include, path2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
