最简单的一个Django项目

 

1. [code]from django.http import HttpResponse
   from django.conf import settings
   from django.urls import path
   import sys
   import os
   
   # setting.py的内容
   DEBUG = os.environ.get('DEBUG', 'on') == 'on'
   SECRET_KEY = os.environ.get('SECRET_KEY', '{{ secret_key }}')
   ALLOWED_HOSTS = os.environ.get('ALLOWED_HOSTS', 'localhost').split(',')
   settings.configure(
   DEBUG=DEBUG,
   SECRET_KEY=SECRET_KEY,
   ALLOWED_HOSTS=ALLOWED_HOSTS,
   ROOT_URLCONF=__name__,
   MIDDLEWARE_CLASSES=(
   'django.middleware.common.CommonMiddleware',
   'django.middleware.csrf.CsrfViewMiddleware',
   'django.middleware.clickjacking.XFrameOptionsMiddleware',
   )
   )
   
   # views.py的内容
   def index(request):
   return HttpResponse('Hello World')
   
   # urls.pyr的内容
   urlpatterns = (
   path('', index),
   )
   
   # manage.py的内容
   if __name__ == '__main__':
   from django.core.management import execute_from_command_line
   execute_from_command_line(sys.argv)

2. [code]$ python3 hello.py runserver

3. [code]这时候在浏览器上输入: 127.0.0.1:8000, 结果显示 'Hello World'
