python - Django channel 不发送回复消息

Question

首先我要说的是:我是 RabbitMQ 及其相关概念的初学者。我想我已经开始理解了。

我目前在使用 Django Channels 时遇到问题。我有一个使用“asgiref.inmemory.ChannelLayer”的设置，目前正在切换到“asgi_rabbitmq.RabbitmqChannelLayer”，这一切似乎工作正常，直到我尝试从浏览器连接到 websocket。有一段时间(7 或 8 秒)没有任何反应，然后突然 websocket.receive 被触发并且 websocket 断开连接。

我认为这是因为回复 channel 没有收到我的接受消息。(或者可能太晚了)。

路由:

lobby_routing = [
    route('websocket.connect', ws_test_add, path=r"^/testadd/$"),
]

消费者:

def ws_test_add(message):
    print "TEST"
    message.reply_channel.send({'accept': True})
    Group("testadd").add(message.reply_channel)

设置:

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "asgi_rabbitmq.RabbitmqChannelLayer",
        "ROUTING": 'CouchGames_Backend.routing.lobby_routing',
        "CONFIG": {
            'url': 'amqp://guest:guest@localhost:5672/%2F',
        },
    },
}

Answer 1

事实证明，这可能是因为 RabbitMQ 并不适合像这样动态创建队列。所以速度太慢导致websocket超时。我切换到 Redis channel 层，现在它似乎工作完美!
