Question

我正在尝试创建具有多个意图的Alexa技能和一个供后端使用的nodeJs服务器。我正在尝试通过WebSocket将意图之一的输入发送到python服务器以对其进行处理，然后检索python服务器的结果，但问题是我无法在意图内部使用websocket。 ps：我尝试通过websocket从nodeJs向python脚本发送一些消息，而没有引入Alexa意图，并且它正常工作

''''''python

class EchoWebSocket(websocket.WebSocketHandler):
    def open(self):
        print ("Websocket Opened")

    def on_message(self, message):
        print('aaaa')
        print('msg',message)
        print('type msg:',type(message))
        a = str(message)
        print('msg to str',a)
        print('type msg to str:',type(a))

    def on_close(self):
        print ("Websocket closed")

application = tornado.web.Application([(r"/", EchoWebSocket),])

if __name__ == "__main__":
    application.listen(991)
    tornado.ioloop.IOLoop.instance().start()
