django 频道私聊

Question

我正在使用 Django 频道创建 Django 私人聊天应用程序。我正面临 Redis 的问题。有人告诉我 Windows OS 不支持 Redis。任何人都可以替代吗？

settings.py Channel_layer

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

您可以为 windows 下载 ubuntu，而不是从 ubuntu 终端下载运行 redis 服务器 - 效果很好。

Answer 2

您可以使用 In Memory Channel 层在 windows 上进行开发。

虽然不鼓励在生产中使用。

CHANNEL_LAYERS = {
    'default': { 
        "BACKEND": "channels.layers.InMemoryChannelLayer"
    },
}
