达芙妮不听Websocket
问题描述：
我有一个使用websockets进行客户端 - 服务器通信的django-channels + celery编写的webapp。在测试运行daphne，芹菜工作人员和redis在我的主机上之后，我决定用docker-compose封装所有东西，以便拥有可部署的系统。达芙妮不听Websocket
这是问题出现的地方。在学习，调整和调试我的docler-compose.yaml之后，我设法让它工作，但仍然无法让websocket再次工作。
如果我打开websocket并从应用程序的javascript部分发送命令，或者从Chrome控制台发出命令，它永远不会触发ws_connect和ws_receive使用者。
这是我的设置：
settings.py
# channels settings
REDIS_HOST = os.environ['REDIS_HOST']
REDIS_URL = "redis://{}:6379".format(REDIS_HOST)
CHANNEL_LAYERS = {
"default": {
"BACKEND": "asgi_redis.RedisChannelLayer",
"CONFIG": {
# "hosts": [os.environ.get('REDIS_HOST', 'redis://localhost:6379')],
"hosts": [REDIS_URL],
},
"ROUTING": "TMWA.routing.channel_routing",
},
}
routing.py
channel_routing = {
'websocket.connect': consumers.ws_connect,
'websocket.receive': consumers.ws_receive,
'websocket.disconnect': consumers.ws_disconnect,
}
consumers.py
@channel_session
def ws_connect(message):
print "in ws_connect"
print message['path']
prefix, label, sessionId = message['path'].strip('/').split('/')
print prefix, label, sessionId
message.channel_session['sessionId'] = sessionId
message.reply_channel.send({"accept": True})
connMgr.AddNewConnection(sessionId, message.reply_channel)
@channel_session
def ws_receive(message):
print "in ws_receive"
jReq = message['text']
print jReq
task = ltmon.getJSON.delay(jReq)
connMgr.UpdateConnection(message.channel_session['sessionId'], task.id)
@channel_session
def ws_disconnect(message):
print "in ws_disconnect"
connMgr.CloseConnection(message.channel_session['sessionId'])

我运行
daphne -b 0.0.0.0 -p 8000 TMWA.asgi:channel_layer
服务器与
python manage.py runworker
我从方程式去除nginx的工人，所以我跑了工人和达芙妮不同的容器中，我想让所有由daphne容器管理的websocket连接然后将计算任务分派给工作人员。问题是，当我打开一个网页套接字和发送数据，什么也没有发生

这个无线电静默之后。在主机上运行所有内容时我输出了输出，但现在我什么也没有。任何想法可能出现问题？
