Django channels 运行三个工人，正常吗？

Question

我有一个非常简单的 Django 项目设置，其中包含使用文档的频道 https://channels.readthedocs.io/en/stable/getting-started.html

在设置中：

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "asgiref.inmemory.ChannelLayer",
        "ROUTING": "core.routing.channel_routing",
    },
}

在rounting.py中：

from channels.routing import route
from apps.prices.consumers import get_prices

channel_routing = [
    route('get_prices', get_prices),
]

当我运行:

python manage.py runserver

它打印：

2016-12-24 23:49:05,202 - INFO - worker - Listening on channels get_prices, http.request, websocket.connect, websocket.receive
2016-12-24 23:49:05,202 - INFO - worker - Listening on channels get_prices, http.request, websocket.connect, websocket.receive
2016-12-24 23:49:05,203 - INFO - worker - Listening on channels get_prices, http.request, websocket.connect, websocket.receive
2016-12-24 23:49:05,207 - INFO - server - Using busy-loop synchronous mode on channel layer

而且三个工人似乎出了问题，还是很正常？但其他一切正常。

非常感谢您的建议

在本地，当我运行 ./manage.py runserver 命令时，默认情况下我有 4 个工人。

可能是通道上的这一行运行服务器命令 - https://github.com/django/channels/blob/a3f4e002eeebbf7c2412d9623e4e9809cfe32ba5/channels/management/commands/runserver.py#L80

要有一个工人运行ning 你可以使用通道命令 ./manage.py runworker。
