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'  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels\sessions.py", line 183, in __call__    return await self.inner(receive, self.send)  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels\middleware.py", line 41, in coroutine_call    await inner_instance(receive, send)  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels\consumer.py", line 59, in __call__    [receive, self.channel_receive], self.dispatch  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels\utils.py", line 59, in await_many_dispatch    await task  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels\utils.py", line 51, in await_many_dispatch    result = task.result()  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels_redis\core.py", line 429, in receive    real_channel  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels_redis\core.py", line 484, in receive_single    index, channel_key, timeout=self.brpop_timeout  File "C:\Users\Unknown\PycharmProjects\online_forum\venv\lib\site-packages\channels_redis\core.py", line 327, in _brpop_with_clean    await connection.eval(cleanup_script, keys=[], args=[channel, backup_queue])  ERR unknown command 'EVAL'WebSocket DISCONNECT /chat/abdullah/ [127.0.0.1:55869]

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"

    },

}
