龙卷风中的 Django 用户

Question

我一直在使用下面的代码在 tornado 中获取 django 用户：

from django.conf import settings
import django.contrib.auth
import django.utils.importlib

import tornado
from tornado.options import options
import tornado.web
import tornado.ioloop
import sockjs.tornado

class RouterConnection(sockjs.tornado.SockJSConnection):

    def get_current_user(self, info):
        engine = django.utils.importlib.import_module(django.conf.settings.SESSION_ENGINE)
        session_key = str(info.get_cookie(django.conf.settings.SESSION_COOKIE_NAME)).split('=')[1]

        class Dummy(object):
            pass

        django_request = Dummy()
        django_request.session = engine.SessionStore(session_key)
        user = django.contrib.auth.get_user(django_request)
        return user


    def on_open(self, info):
        user = self.get_current_user(info=info)

if __name__ == "__main__":
    import logging
    Router = sockjs.tornado.SockJSRouter(RouterConnection)

    app = tornado.web.Application(Router.urls, debug=True, )

    app.listen(settings.TORNADO_PORT)

    tornado.options.parse_command_line()
    tornado.ioloop.IOLoop.instance().start()

我的问题如下：
Django 更改了日志配置，我再也看不到龙卷风的任何日志输出。如何重新初始化龙卷风日志记录？还有其他方法可以将 Django 与 Tornado 集成吗？

非常感谢。

要重置 django 日志记录，我使用以下命令：

logger = logging.getLogger('')
for handler in logger.handlers:
    logger.removeHandler(handler)
tornado.options.parse_command_line()

当使用 django.conf 模块时，LazySettings 类在初始化 django 记录器的地方被初始化。 我还必须使用初始化设置类重写代码：

from django.conf import settings
import django.contrib.auth
import django.utils.importlib

import tornado
from tornado.options import options
import tornado.web
import tornado.ioloop
import sockjs.tornado

TORNADO_PORT = settings.TORNADO_PORT

class RouterConnection(sockjs.tornado.SockJSConnection):

    def get_current_user(self, info):
        engine = django.utils.importlib.import_module(settings.SESSION_ENGINE)
        session_key = str(info.get_cookie(settings.SESSION_COOKIE_NAME)).split('=')[1]

        class Dummy(object):
            pass

        django_request = Dummy()
        django_request.session = engine.SessionStore(session_key)
        user = django.contrib.auth.get_user(django_request)
        return user


    def on_open(self, info):
        user = self.get_current_user(info=info)

if __name__ == "__main__":
    import logging
    logger = logging.getLogger('')
    for handler in logger.handlers:
        logger.removeHandler(handler)
    tornado.options.parse_command_line()

    Router = sockjs.tornado.SockJSRouter(RouterConnection)

    app = tornado.web.Application(Router.urls, debug=settings.DEBUG)

    app.listen(settings.TORNADO_PORT)

    tornado.options.parse_command_line()
    tornado.ioloop.IOLoop.instance().start()

使用tornado.wsgi.WSGIContainer 包装Django。有关工作示例，请参阅 this demo project。
