python - Tornado 中的 Django 用户

Question

我一直在使用下面的代码来获取 Tornado 中的 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 更改了日志记录配置，我再也看不到 tornado 的任何日志输出。如何重新初始化 Tornado 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()
