我正在尝试设置django-channels。
我按照说明做了所有的事情，但是当我试图连接时，我得到一个404 error - page not found。
我从本地主机向开发服务器发出请求。

在Nginxaccess.log中我看到
[17/Sep/2021:11:54:54 +0000] "GET /ws/mark/ HTTP/1.1" 404 1100 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.82 Safari/537.36"
我尝试了uvicorn。不影响…
我使用Python 3.8
Django
2.2channels-redis 3.3.0
频道3.0.4
复述3.5.3
更改nginx.conf位置为
location / {
proxy_pass http://vv-fix-backend:8010;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
}
