django - django 承接nginx请求

import os
import sys
import tornado.ioloop
import tornado.web
import tornado.wsgi
import tornado.httpserver
from django.core.handlers.wsgi import WSGIHandler

# 设置 Django 设置模块，sets the default settings module to use
_HERE = os.path.dirname(os.path.abspath(__file__))
sys.path.append(_HERE)
os.environ['DJANGO_SETTINGS_MODULE'] = "settings"

def main(port):
    # 利用 tornado 的http server处理消息请求
    wsgi_app = tornado.wsgi.WSGIContainer(WSGIHandler())
 
    # Application 处理请求消息
    tornado_app = tornado.web.Application(
        # FallbackHandler： A RequestHandler that wraps another HTTP server callback. 
        # http://www.tornadoweb.org/en/stable/web.html#tornado.web.FallbackHandler
        [('.*', tornado.web.FallbackHandler, dict(fallback=wsgi_app)),
        ])

    # HTTPServer is a very basic connection handler. It parses the request headers and body
    server = tornado.httpserver.HTTPServer(tornado_app)
    server.listen(port)
    tornado.ioloop.IOLoop.instance().start()

if __name__ == '__main__':
    try:
        import setproctitle
        setproctitle.setproctitle('www:' + sys.argv[1])
    except ImportError:
        pass
    main(int(sys.argv[1]))

基本思想：利用 tornado 的 http server，处理消息请求。

官方文档有介绍：

• WSGIContainer lets you run other WSGI applications and frameworks on the Tornado HTTP server. For example, with this class you can mix Django and Tornado handlers in a single server.
