将Elastic Beanstalk与Django频道一起使用时出现Websocket错误

Question

我正在尝试使用django渠道的聊天应用程序来使用负载均衡器在AWS Elastic Beanstalk上运行.

我基本上修改了https://github.com/jacobian/channels-example中的代码以使用Elastic Beanstalk.我可以使用该命令在本地成功运行它

python manage.py runserver

问题是当我使用Elastic Beanstalk部署它时,我在启动聊天应用程序时收到以下错误

WebSocket connection to 'wss://mydomain.com/test/' failed: Error 
during WebSocket handshake: Unexpected response code: 200

我尝试了在/sf/answers/2088220641/上提出的解决方案,但它只显示了不同的错误代码

WebSocket connection to 'wss://mydomain.com/test/websocket' failed: 
Error during WebSocket handshake: Unexpected response code: 404

我还已将负载均衡器侦听器端口更改为TCP 80并获得SSL证书以将安全侦听器端口更改为SSL 443,但仍会收到相同的错误.

我还在AWS Elastic Beanstalk上阅读了带有socket.io的Websockets,但是没有为Django配置代理服务器的选项,我认为它默认使用Apache.

我对Elastic Beanstalk的配置缺少什么使它工作？

有没有办法改变这个,所以我们可以用asgi运行daphne服务器？

我没有使用 Elastic Beanstalk，但这是我的 VPS 配置。Ubuntu 14.04，带有 nginx 和supervisor。Supervisor 的工作是确保服务器和工作进程始终运行。Nginx 监听本地主机上的 8000 端口并将其转发到 8080 和 443。

# nginx.conf
server {
    listen 8080 default_server;
    server_name example.com;
    return 301 https://example.com$request_uri;
}

server {
    listen 443 default_server ssl;
    server_name example.com;

    # ... SSL stuff

    # Send root to the ASGI server
    location / {
        proxy_pass http://localhost:8000;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }

    # Static Files
    location /static/ {
        root /home/ubuntu/project;
    }

    # Media Files
    location /media/ {
        root /home/ubuntu/project;
    }
}

这是我的主管配置。我只需重新启动主管即可启动服务器sudo service supervisor restart

# supervisord.conf
