你好很棒的人!
我创建了一个聊天室django-channels。每次我在生产环境中尝试通过网络套接字连接到我的聊天室时,它都会失败。在本地它可以正常工作。
我在digitalocean上主持
点冻结:
channels==2.1.2
channels-redis==2.3.0
daphne==2.2.1

我一直在 firefox 和其他浏览器中得到类似的东西:
Firefox 无法与位于 wss://www.domain_name.com/url-to/1/XBvZjr2pqdf6fhy/ 的服务器建立连接
但是它在本地工作。
更新
这是我的js
var loc = window.location;
var wsStart = loc.protocol == "https:" ? "wss://" : "ws://"
var endpoint = wsStart + loc.host + loc.pathname
var socket = new ReconnectingWebSocket(endpoint);
socket.onmessage = function(e){
// code
}

我终于解决了这个问题,并ws在ssl与wss://.
对于那些面临同样问题的人。
请注意,我使用
gunicorn作为仅用于http请求的Web 服务器daphne作为ws网络套接字的网络服务器nginx 作为反向代理asgi.py

asgi用 django设置后,我supervisorctl用来继续daphne运行。创建一个文件daphne_asgi.conf中/etc/supervior/conf.d/
daphne_asgi.conf
[program:asgi_daphne]
directory=/path/to/your/project
command=/executable/path/to/daphne --bind 0.0.0.0 --port 8010 project.asgi:application
# 0.0.0.0 ip of your website
