from channels.generic.websocket import WebsocketConsumer
from channels.exceptions import StopConsumerclass ChatConsumer(WebsocketConsumer):def websocket_connect(self, message):self.accept()def websocket_receive(self, message):print('接收到消息', message)self.send(text_data='收到了')def websocket_disconnect(self, message):print('客户端断开连接了')raise StopConsumer()
