世界上最小的Django项目示例

一. 世界上最小的Django项目示例

# hello.py
import os
import sys

from django.conf import settings

DEBUG = os.environ.get("DEBUG","on") == "on"
SECRET_KEY = os.environ.get("SECRET_KEY","{{ secret_key }}")
ALLOWED_HOSTS = os.environ.get("ALLOWED_HOST","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',
    ),
)

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

def index(request):
    return HttpResponse('Heello World')
    
urlpatters = (
    url(r'^$',index),
)

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

运行

$ python hello.py runserver

二. 使用gunincorn运行python服务

# cat hello.py
from django.conf.urls import url
from django.core.wsgi import get_wsgi_application
from django.http import Httpresponse

application = get_wsgi_application()

if __name == "__main__":
   from django.core.management import execute_from_command_line
   execute_from_command_line(sys.argv)

安装gunicorn并运行

# pip install gunicorn
# gunicorn hello --log-file=-
