Apache配置Daphne实现Django WebSocket连接失败求助

核心问题分析 #

从错误日志Not Found: /ws/video_call/可以看出，WebSocket请求被Apache的WSGI模块处理了，没有转发到Daphne服务器。当前Apache配置存在两处关键错误：

1. WebSocket代理配置放在了80端口的虚拟主机中，而请求通过HTTPS（wss协议）访问，80端口的重定向规则会导致代理规则失效。
2. ProxyPass目标使用了wss://kartikprajapati.com:8001/，但Daphne监听的是普通HTTP（ws）端口，转发时无需使用SSL。

分步解决方案 #

1. 修正Apache HTTPS虚拟主机配置 #

创建或修改HTTPS虚拟主机配置文件（通常位于/etc/apache2/sites-available/目录，示例文件名为kartikprajapati.com-le-ssl.conf）：

<VirtualHost *:443>
    ServerName www.kartikprajapati.com
    ServerAdmin kartikprajapati26122004@gmail.com

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # SSL证书配置（根据实际证书路径调整）
    SSLCertificateFile /etc/letsencrypt/live/www.kartikprajapati.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/www.kartikprajapati.com/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf

    # 静态/媒体文件映射
    Alias /static /var/www/mywebsite/static
    <Directory /var/www/mywebsite/static>
        Require all granted
    </Directory>

    Alias /media /var/www/mywebsite/media
    <Directory /var/www/mywebsite/media>
        Require all granted
    </Directory>

    # WebSocket转发规则
    RewriteEngine On
    # 匹配WebSocket升级请求，转发到Daphne
    RewriteCond %{HTTP:Upgrade} =websocket [NC]
    RewriteRule /ws/(.*) ws://localhost:8001/ws/$1 [P,L]

    # 普通HTTP请求由WSGI处理
    WSGIDaemonProcess mywebsite python-home=/var/www/mywebsite/venv python-path=/var/www/mywebsite
    WSGIProcessGroup mywebsite
    WSGIScriptAlias /  /var/www/mywebsite/mywebsite/wsgi.py

    <Directory /var/www/mywebsite/mywebsite>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    # 确保WebSocket路径不被WSGI拦截
    <Location /ws/>
        ProxyPass ws://localhost:8001/ws/
        ProxyPassReverse ws://localhost:8001/ws/
        ProxyPreserveHost On
    </Location>
</VirtualHost>

2. 简化80端口虚拟主机配置 #

保留80端口的重定向规则即可，删除原有的WebSocket代理配置：

<VirtualHost *:80>
    ServerName www.kartikprajapati.com
    ServerAdmin kartikprajapati26122004@gmail.com

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    RewriteEngine on
    RewriteCond %{SERVER_NAME} =www.kartikprajapati.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

3. 验证Apache模块是否启用 #

确保所需模块已启用并重启Apache：

a2enmod proxy proxy_http proxy_wstunnel rewrite
systemctl restart apache2

4. 检查ASGI路由与Daphne配置 #

• 当前asgi.py中的路由配置无需修改，路径ws/video_call/与转发规则匹配：

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

• 重启Daphne服务确保配置生效：

systemctl restart daphne

验证步骤 #

1. 使用wscat工具测试WebSocket连接（需先安装npm install -g wscat）：

wscat -c wss://www.kartikprajapati.com/ws/video_call/

连接成功会显示connected (press CTRL+C to quit)。

2. 查看日志排查问题：

• Apache错误日志：tail -f /var/log/apache2/error.log
• Daphne日志：journalctl -u daphne -f

额外排查点 #

• 检查Djangosettings.py中的ALLOWED_HOSTS是否包含www.kartikprajapati.com
• 确保服务器防火墙未拦截本地8001端口（同一服务器内转发无需开放外部端口）
• 验证VideoConsumers类是否正确实现了connect()、disconnect()等必要方法
