使用consumers.py 之外的渠道，但在consumer 中的功能没有触发

Question

我试图在用户登录后将消息从一个用户发送到另一个用户到另一个用户。但是，chat_message 函数似乎没有使用我在视图中的登录函数中编写的代码触发.py 作为“ccc”而不是在服务器端打印。 Django 频道的新手在这里。感谢您对我的这个问题的任何意见。

consumers.py

class OnlineFriends(AsyncWebsocketConsumer):
    async def connect(self):
        self.room_name = self.scope["user"]
        print(self.room_name)
        print(self.channel_layer)
        self.room_group_name = 'chat_' + str(self.room_name)
        print(self.room_group_name)
        # Join room group
        await self.channel_layer.group_add(
            self.room_group_name,
            self.channel_name
        )

        await self.accept()

    async def disconnect(self, close_code):
        print("aa")

        message = self.channel_name.split("-")
        await self.send(text_data=json.dumps({
                'message': message
            }))

    async def receive(self, text_data):
        text_data_json = json.loads(text_data)
        message = text_data_json['message']

        # Send message to room group
        await self.channel_layer.group_send(
            self.room_group_name,
            {
                'type': 'chat_message',
                'message': message
            }
        )

    async def chat_message(self, event):
        print("ccc")
        message = event['message']

        # Send message to WebSocket
        await self.send(text_data=json.dumps({
            'message': message
        }))
