wsgi_websockets.py

 import os
 import gevent.socket
 import redis.connection

 redis.connection.socket = gevent.socket
 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bxd.settings")
 from ws4redis.uwsgi_runserver import uWSGIWebsocketServer
 application = uWSGIWebsocketServer()

上述功能在

/manage.py runserver

上运行良好，但在nginx上则不行

任何帮助都将不胜感激
