HTTP请求的url路由

创建一个名为sales的app：python manage.py startapp sales

路由显示

bysms/urls.py

from django.contrib import admin
from django.urls import path,include
from sales.views import listordersurlpatterns = [path('admin/', admin.site.urls),path('sales/orders/',listorders),]

view.py 

from django.http import HttpRequest, HttpResponse
from django.shortcuts import renderdef listorders(request):#返回的HTTP响应消息；消息体为...return HttpResponse('下面是系统中所有的订单信息...')

一级路由二级路由

一级路由bysms/urls.py

from django.contrib import admin
from django.urls import path,include
from sales.views import listordersurlpatterns = [path('admin/', admin.site.urls),# #主路由表path('sales/',include('sales.urls'))
]

二级路由sales/urls.py 

from django.urls import path
from sales.views import listordersurlpatterns =[#二级路由表path('orders/',listorders)
]

 创建数据库

 这里使用的是数据库 sqlite

 bysms/settings.py

DATABASES = {'default': {'ENGINE': 'django.db.backends.sqlite3','NAME': BASE_DIR / 'db.sqlite3',}
}
