Django通道会话问题，Redis作为通道层后端

我将Django通道与单独的Javascript前端结合使用。WebSocket工作正常。我现在想做的是：

• 当用户打开网站时，后端会生成一个特定的id。后端会将该id保存在带有

  消息的会话中。channel\u会话['my\u id']

• 在随后通过websocket调用后端时，我希望从会话中检索该密钥

然而，有时这似乎是可行的，有时我会得到一个

KeyError

<代码>我的id似乎不存在。我的代码：

routing.py

：

from channels.routing import route
from chat.consumers import ws_connect, ws_receive

channel_routing = [
    route("websocket.connect", ws_connect),
    route("websocket.receive", ws_receive),
]

import uuid
from channels.sessions import channel_session


@channel_session
def ws_connect(message):
    message.channel_session['my_id'] = str(uuid.uuid4())

@channel_session
def ws_receive(message):
    my_id = message.channel_session['my_id']  # this one sometimes fails...

和

consumers.py

：

from channels.routing import route
from chat.consumers import ws_connect, ws_receive

channel_routing = [
    route("websocket.connect", ws_connect),
    route("websocket.receive", ws_receive),
]

import uuid
from channels.sessions import channel_session


@channel_session
def ws_connect(message):
    message.channel_session['my_id'] = str(uuid.uuid4())

@channel_session
def ws_receive(message):
    my_id = message.channel_session['my_id']  # this one sometimes fails...

但是，当我将通道层后端从Redis切换到内存中时，它工作正常（我使用

/manage.py runserver

，因此我不运行单独的工作程序）

有什么想法吗？是否存在竞争条件或其他问题？

您是否尝试过创建

websocket\u keepalive

消费者？您解决了这个问题吗？
