目录结构

views.py 存放函数

创建简单页面

# 1.在views.py中定义函数
from django.http import HttpResponse


def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

# 2.在urls.py中添加路由
from django.urls import path
from game.views import index

urlpatterns = [
    path('', index, name='index'),
]

# 3.在全局的app中的urls.py中include urls
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('game/', include('game.urls')),
]

#访问:http://localhost:8000/game/ 
#显示:Hello, world. You're at the polls index.
