轻量级django 一

from django.http import HttpResponse
from django.conf.urls import url
from django.conf import settings
import sys

settings.configure(
    DEBUG = True,
    SECRET_KEY = "HAHA",
    ROOT_URLCONF = __name__,
    MIDDLEWARE_CLASSES = (
        'django.middleware.common.CommonMiddleware',
        'django.middleware.csrf.CsrfViewMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
        ),
    )

def index(request):
    return HttpResponse("hello world")

urlpatterns = (
    url(r'^$',index),
    )

if __name__ == '__main__':
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

完善后

from django.http import HttpResponse
from django.conf.urls import url
from django.conf import settings
from django.core.wsgi import get_wsgi_application
import sys
import os

DEBUG = os.environ.get('DEBUG','on') == 'on'
SECRET_KEY = os.environ.get('SECRET_KEY','=3k+l%xeb=fp@04uci&wy&ca14*@7ebxsu*6jd_ym1t3k^w)v*')
ALLOWED_HOSTS = os.environ.get('ALLOWED_HOSTS','localhost').split(',')

settings.configure(
    DEBUG = DEBUG,
    SECRET_KEY = SECRET_KEY,
    #ALLOWED_HOSTS = ALLOWED_HOSTS,
    ALLOWED_HOSTS= ALLOWED_HOSTS,
    ROOT_URLCONF = __name__,
    MIDDLEWARE_CLASSES = (
        'django.middleware.common.CommonMiddleware',
        'django.middleware.csrf.CsrfViewMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
        ),
    )

def index(request):
    return HttpResponse("hello world")

urlpatterns = (
    url(r'^$',index),
    )

application = get_wsgi_application()

if __name__ == '__main__':
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

更轻量的django

from django.conf import settings
from django.http import HttpResponse
from django.conf.urls import url

setting = {
    'DEBUG':True,
    'ROOT_URLCONF':__name__
}

settings.configure(**setting)

def home(request):
    return HttpResponse('hello world')

urlpatterns = [url('^$',home,name='home')]

if __name__ == '__main__':
    import sys
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

python test runserver
