Question

我正在尝试创建一个聊天，当它满足“hola”条件时，由芹菜中的任务发送。但是，当它进入状态时状态没有更新，有人可以帮助我吗？

我留下我的代码，请帮助！

Mi错误是：

提出OSError（错误，'连接调用失败％s'％（地址，）） ConnectionRefusedError：[Errno 10061]连接呼叫失败（':: 1'，6379）

    import json

from .tasks import MensajeAlGrupo

class Consumidor(AsyncWebsocketConsumer):
    async def connect(self):
        # Join room group
        await self.channel_layer.group_add(
            'grupo',
            self.channel_name
        )
        await self.accept()

    async def disconnect(self, close_code):
        await self.channel_layer.group_discard(
            'grupo',

         )

    # Receive message from WebSocket
    async def receive(self, text_data):
        text_data_json = json.loads(text_data)
        message = text_data_json['message']
        if str(message) == "hola":
            MensajeAlGrupo.delay()
        else:

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

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

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

Tasks.py

    #De celery
from Filtros.celery import app
from channels.layers import get_channel_layer


@app.task()
def MensajeAlGrupo():
    channel_layer = get_channel_layer()
    async_to_sync(channel_layer.group_send)(
        'grupo',
        {"type": "chat.message", "message": "Hello World"},
    )

请帮帮我，谢谢！

问题出现在windows中“localhost”的settings.py中，将“localhost”更改为127.0.0.1

<强> Settings.py

#------------------ CONFIGURACION DE LOS CHANNELS -----------------#
redis_host = os.environ.get('REDIS_HOST', '127.0.0.1')

# Channel layer definitions
CHANNEL_LAYERS = {
    "default": {
        # This example app uses the Redis channel layer implementation channels_redis

        "CONFIG": {
            "hosts": [(redis_host, 6379)],
        },
    },
}

# ASGI_APPLICATION should be set to your outermost router
