使用django频道发送相机图像,但在最后几次之后总是关闭

这是我的消费者,我想使用django频道发送相机图像,但总是在最后几次之后关闭,不知道为什么

你能告诉我它是否设置不正确吗?我使用Redis作为通道层

import json
from channels.generic.websocket import AsyncWebsocketConsumer


class ObjectDetectionConsumer(AsyncWebsocketConsumer):
    async def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['v_name']
        self.room_group_name = 'ObjectDetection_%s' % self.room_name
        print(self.room_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):
        # Leave room group
        await self.channel_layer.group_discard(
            self.room_group_name,
            self.channel_name
        )

    # Receive message from WebSocket
    async def receive(self, text_data):
        print("receive! ")
        # Send message to room group
        await self.channel_layer.group_send(
            self.room_group_name,
            {
                'type': 'video_message',
                'message': text_data,
            }
        )

    # Receive message from room group
    async def video_message(self, event):
        # print(1)
        message = event['message']

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

这是错误的信息

大约一分钟后,它将自动断开连接。你需要断开连接再重新连接吗?
