django 创建一个app_使用url

1、创建文件

django-admin startproject myweb

cd ui

python manage.py startapp myapp

2、修改myapp下的views文件

以显示“hello,world.”为例子。

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def hello(request):
return HttpResponse('Hello, World.')

添加如下内容

from django.conf.urls import url
from . import views

urlpatterns =[
url('hello',views.hello,name='hello')
]

修改文件，添加myapp下文件地址

from django.conf.urls import url, include

并添加url('myapp/',include('myapp.urls'))

最后文件如下：

from django.contrib import admin
from django.urls import path
from django.conf.urls import url, include

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

python manage.py runserver

输入http://127.0.0.1:8000/myapp/hello，网页显示hello,world.
