Question

我的频道有一个非常大的问题。当我尝试在生产中运行 asgi 服务器时出现问题，但在终端中运行时没有问题。

先给大家看一段代码

class LogConsumer(AsyncConsumer):
    async def websocket_connect(self, event):
        print('befor')

        await  self.send({

            "type": "websocket.accept",
            "text": "hellow"
        })
        print('after')
    async def websocket_disconnect(self, event):
        print(event)

还有更多，但我也评论了它们，看看问题是否正在解决，猜猜是什么......

    application = ProtocolTypeRouter({
        'websocket': AllowedHostsOriginValidator(
            AuthMiddlewareStack(
                URLRouter(
                    [
                        url(r"^ws/monitoring/$", LogConsumer),
    
                    ]
                )
            ),
    
        )
    })



ASGI_APPLICATION = "fradmin_mainserver.routing.application"



CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("localhost", 6379)],
        },
    },
}
ASGI_THREADS = 1000

主管配置

[fcgi-program:asgi]
socket=tcp://localhost:8008
environment=PYTHONPATH=/home/datis/.pyenv/versions/cv/bin/python
User=datis
environment=HOME="/home/datis",USER="datis"
# Directory where your site's project files are located
directory=/home/datis/PycharmProjects/fradmin_mainserver/

# Each process needs to have a separate socket file, so we use process_num
# Make sure to update "django_chanels.asgi" to match your project name
command=/home/datis/.pyenv/versions/cv/bin/daphne -u /run/uwsgi/daphne%(process_num)d.sock --fd 0 --access-log - --proxy-headers fradmin_mainserver.asgi:application

# Number of processes to startup, roughly the number of CPUs you have
numprocs=1

# Give each process a unique name so they can be told apart
process_name=asgi%(process_num)d

# Automatically start and recover processes
autostart=true
autorestart=true

# Choose where you want your log to go
stdout_logfile=/var/log/uwsgi/asgi.log
redirect_stderr=true

好的，这些是配置。

当我使用

daphne fradmin_mainserver.asgi:application --bind 0.0.0.0 --port 8008 --verbosity 1

没有问题，但是当在主管内部使用它时，我唯一得到的是：

2021-04-13 11:45:27,015 WARNING  Application instance <Task pending coro=<SessionMiddlewareInstance.__call__() running at /home/datis/.pyenv/versions/3.6.8/envs/cv/lib/python3.6/site-packages/channels/sessions.py:183> wait_for=<Future pending cb=[<TaskWakeupMethWrapper object at 0x7f02e2222d38>()]>> for connection <WebSocketProtocol client=['127.0.0.1', 46234] path=b'/ws/monitoring/'> took too long to shut down and was killed.

即使我尝试使用当前代码启动服务并且我做到了：

[Unit]
Description=daphne daemon
After=network.target


[Service]
PIDFile=/run/daphne/pid
User=root
Group=root
WorkingDirectory=/home/datis/PycharmProjects/fradmin_mainserver/
Environment="DJANGO_SETTINGS_MODULE=fradmin_mainserver.settings"
ExecStart=/home/datis/.pyenv/versions/cv/bin/daphne --bind 0.0.0.0 --port 8008 --verbosity 0 fradmin_mainserver.asgi:application
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
Restart=on-abort
PrivateTmp=true
StandardOutput=file:/var/log/daphne/access.log
StandardError=file:/var/log/daphne/access.log


[Install]
WantedBy=multi-user.target

但结果是一样的：

它就像 websocket_connec() 永远不会被调用

我尝试使用 syncconsumer 创建它，但问题是相同的

但是当我停止 supervisorctl 时所有运行在一起

帮我取悦一个真正的产品项目，我不再做什么我尝试了一切并阅读了堆栈溢出github等中的每一行。
