如何使用龙卷风服务器运行额外的线程？

Question

我有一个运行django应用程序的龙卷风服务器。 我有一个问号驱动程序，可以连接到正在运行的大多数服务器。

我正在尝试使两者一起工作，但从另一个开始。 我尝试对一个进程进行线程处理并得到“ RuntimeError：线程'Thread-1'中没有当前事件循环”

def main():


    wsgi_app = tornado.wsgi.WSGIContainer(
            django.core.handlers.wsgi.WSGIHandler())
    tornado_app = tornado.web.Application(
        [
            (r'/static/(.*)', NoCacheStaticHandler, {'path': 'static'}),
            ('/hello-tornado', HelloHandler),
            ('/websocket', WebSocketHandler),
            ('.*', tornado.web.FallbackHandler, dict(fallback=wsgi_app)),
            ])
    server = tornado.httpserver.HTTPServer(tornado_app)
    server.listen(options.port)
    instance = tornado.ioloop.IOLoop.instance()
    p = threading.Thread(target=mattermost_chat,args=(instance,))
    p.start()
    instance.start()

def mattermost_chat(parameter):
    print(parameter)
    chat = Chat()
    chat.login()
    chat.connect()

if __name__ == '__main__':
    #mattermost_chat()
    main()

示例运行。
