Tornado websockets with nginx reverse proxy

[Roman]

Dear,

I know, that this doesn't fully belong here, but I hope that you can help me.

I'm training to use nginx reverse proxy to redirect websockets to tornado server...

Tornado websocket handler works properly... But trough nginx, it changes ws:// to http:// with GET request

I have read this "how-to"  http://nginx.org/en/docs/http/websocket.html and some other "Q&A" but it still not works... 

map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
}


server {
    listen 5252;


    location /ws {
        proxy_pass http://127.0.0.1:10001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_read_timeout 86400;
    }
   
    . . .

}

From tornado I recieve:

WARNING:tornado.access:403 GET /ws/ (127.0.0.1) 0.38ms

With HTTP/GET method it works well. 

Thank you so much for all answers,

and have a nice day!

Hi:

Since Tornado 4.0 WebSocketHandler requires applications that wish to receive cross-origin websockets to opt in by overriding the check_origin method.

so, you can change your handler and overwrite "check_origin" like this:

class MainHandler(tornado.websocket.WebSocketHandler):

    def check_origin(*args, **kwargs):
        return True

​

Then, it will work.
