如何配置uwsgi + nginx + Django + websocket？

Question

I successfully deployed uwsgi + nginx + Django. But I want to communicate with my server using websocket.

I followed this tutorial to handle normal https requests. https://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html

The nginx conf file settings are like this:

upstream django {
    server unix:///path/to/your/mysite/mysite.sock; # for a file socket
}

# configuration of the server
server {
    # the port your site will be served on
    listen 443 ssl; # managed by Certbot
    # the domain name it will serve for
    server_name example.com; # substitute your machine's IP address or FQDN
    charset     utf-8;



    location /static {
        alias /path/to/your/mysite/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /path/to/your/mysite/uwsgi_params; # the uwsgi_params file you installed
    }
}

I Googled a lot and found that people recommended to add these settings:

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;

It does not work. I did not use proxy_pass because I am already using uwsgi_pass django; and my client attempts to connect using websocket to the same url (location) I uwsgi_pass to django. I looked into uwsgi docs and found this page: https://uwsgi-docs.readthedocs.io/en/latest/WebSockets.html

According to this page, I do not need additional settings if I just add --http-websockets option. So I did. Like this:

/usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals --http-websockets www-data --daemonize /var/log/uwsgi-emperor.log

It is added in /etc/rc.local. This command does not work either. I also tried to add http-websockets = true to.ini file. It even made uwsgi stop. So I removed that option.

What is wrong here?

I get 400 Bad Request for every websocket request. The only data I see is (Opcode -1). There is no graphql error message.

You need to change socket type from.sock to net (ip:port). And use this consruction on NGinx "proxy" and server with django.
