使用daphne上传django项目的Apache websocket连接

Question

asg.py

import os

from django.urls import re_path

from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from channels.security.websocket import AllowedHostsOriginValidator
import django
from django.urls import path 

from django.core.asgi import get_asgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mywebsite.settings')
os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true"

django.setup()

from video.consumers import VideoConsumers
from chat.consumers import Myconsumers


application = get_asgi_application()

application = ProtocolTypeRouter({
    "http":application,
    "websocket": AllowedHostsOriginValidator(
        AuthMiddlewareStack(
            URLRouter(
                [
                path("ws/video_call/",VideoConsumers.as_asgi()),
                path('ws/ac/<str:uuid>/',Myconsumers.as_asgi())
                    
                ]
                
            )
        )
    ),

})

每当我致电 wss://kartikprajapati.com/ws/video_call/ 时，它都会显示错误，请帮忙

我已经做到了

a2enmod proxy rewrite proxy_http proxy_wstunnel

错误：-

[2024 年 5 月 8 日星期三 16:01:15.693322] [wsgi:error] [pid 30048:tid 140661514831552] [远程 49.36.71.188:54708] 未找到：/ws/video_call/ websocket 未连接

如果您想了解有关我的代码和配置的更多信息，请评论

我已经修复了 2 到 3 天，如果您知道任何事情请帮忙

我已经完成了很多配置，但它没有帮助我想知道如何一步步处理它，因为 https 正在工作，但 wss 不是 wokring

Answer 1

如果您尝试在本地运行此程序，则需要删除

wss

的代理并使用

ws

。

为了在互联网上运行应用程序，我们需要将

wss

与

https

一起使用，而您的应用程序则使用

http

。另外，您似乎正在使用

asgi.py

和 asgi 应用程序，但您的 apache 代码定义了 wsgi 应用程序，这是不必要的。将 Daphne 与 Django Channels 结合使用，我们使用的是异步版本 asgi。

这是一个在 Ubuntu Linux 服务器上与 Daphne 和 Django Channels 一起使用用于 Websockets 的 Apache 服务器配置。

RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC,OR]
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
RewriteRule .* ws://127.0.0.1:8001%{REQUEST_URI} [P,QSA,L]
ProxyPass /wss/ wss://127.0.0.1:8001/

建议运行此命令在生产级服务器上运行 Daphne，我包含了一个在本地服务器上运行 Daphne 的命令。在生产级别，您需要 Kubernetes 或 Docker 容器来保持 Daphne 运行。

daphne -b 0.0.0.0 -p 8001 django_project.asgi:application // Local Development Level
daphne -e ssl:443:privateKey=key.pem:certKey=crt.pem django_project.asgi:application // Production Level
