django 频道私聊

Question

我正在使用 Django 频道创建一个 Django 私人聊天应用程序。我正面临 Redis 的问题。有人告诉我 Windows 操作系统不支持 Redis。任何人都可以有替代品吗？

settings.py 通道层

CHANNEL_LAYERS = {

    "default": {

        "BACKEND": "channels_redis.core.RedisChannelLayer",

        "CONFIG": {

            "hosts": [("localhost", 6379)],

        },

    },

}

显示的错误是

connected {'type': 'websocket.connect'}

WebSocket CONNECT /chat/abdullah/ [127.0.0.1:55869]

Exception inside application: ERR unknown command 'EVAL'

Answer 1

您可以下载适用于 Windows 的 ubuntu，而不是从 ubuntu 终端运行 redis 服务器 - 效果很好。

Answer 2

您可以在 Windows 上使用In Memory Channel Layer 进行开发。虽然不鼓励在生产中使用。CHANNEL_LAYERS = {    'default': {         "BACKEND": "channels.layers.InMemoryChannelLayer"    },}
