Django最小程序

from django.conf.urls import url
from django.conf import settings
from django.http import HttpResponse
from django.core.management import execute_from_command_line

# 设置框架配置
settings.configure(
    DEBUG= True, # 和flask的debug一样
    SECRET_KEY= 'aaa', # 用于加密的字符串
    ROOT_URLCONF=__name__,  # 此配置为在当前文件里面找url映射的配置
    MIDDLEWARE_CLASSES=(

        'django.middleware.csrf.CsrfViewMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
        )

# 视图函数
def index(request):
    return HttpResponse( 'hello world')

# 通过正则匹配url，做视图映射
urlpatterns = (
    url(r'^$', index),
    )
