在我安装了letsencript ssl 之前,Django-channels websocket 在AWS 服务器上运行良好。我尝试了另一个证书,但 wss 无法正常工作。我看到了这个在线部署,它表明通道可以在 https 后面工作:
https://django-channels-example.herokuapp.com/
我在这里遵循了 andrewgodwin 的建议:
https://github.com/django/channels/issues/248
我将 daphne 指向 8000 端口:
daphne -b 0.0.0.0 vp.asgi:channel_layer --port 8000 -v 2
我在我的 javascript 中使用了相同的端口:
chatsock = new WebSocket( ws_scheme + '://' + window.location.host + ":8000/chat" );
我的 nginx 配置:
server {
listen 80;
server_name mysite.com www.example.com;
return 301 https://www.example.com$request_uri;
}
server{
listen 443 ssl;
server_name mysite.com www.example.com;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

}
location ~ /.well-known {
allow all;
}
location /static/ {
alias /home/ubuntu/vp/static/;

}
}
我的浏览器告诉我:
Firefox 无法与位于 wss://example.com:8000/chat 的服务器建立连接。
有什么建议么?谢谢。
