proxmox vncwebsocket

[liuzezhong]

I had some problems with proxmox.

Please help me.

I tried to connect to VNC using the proxmox API (local, not using the console in the proxmox web panel) through noVNC.

I send POST requests to/api2 / json/nodes / {node} / qemu / {vmid} / vncproxy to get vncticket and port.
Then, I pass the vncticket and give the port GET/api2 / json/nodes / {node} / qemu / {vmid} / vncwebsocketbut instead of websocket, which always returns null. {" data ": null}.

And the HTTP status is the 401 permissions denied - invalid PVEVNC ticket.

I can't find any mistakes.

I follow the steps above and use the root account.

Proxmox 5.1

i moved your thread to the english forums

also if you want to use a websocket, you have to make a websocket connection
e.g. it has to have an 'upgrade' header and some other things, see here:

https://developer.mozilla.org/en-US...ing_WebSocket_servers#The_WebSocket_Handshake

edit:

oh and also the websocket connection has to have a valid pve auth cookie set

I was trying the same and notice that vncticket have to be url encoded to work properly.

In my case, i receive HTTP 101 response, which is correct, but noVNC asks me for authentication. I'm trying to figure out which password is it.
All the help is welcome.

Well, answering my own question:
The password needed is the vncticket.

The issue is likely caused by improper handling of the VNC ticket. Ensure that the vncticket is URL-encoded before passing it in the request.

how did you test in postman. this is mine https://proxmox-api:8006/api2/json/nodes/server11/qemu/155/vncwebsocket?port=5900&vncticket=PVENC

I am also using a react js framework

I worked with Angular, and my TypeScript code is structured like this:

const encodedTicket = encodeURIComponent(ticket);
const websocketUrl = `wss://pve-node-ip:8006/api2/json/nodes/${node}/qemu/${vmid}/vncwebsocket?port=${port}&vncticket=${encodedTicket}`;

If you want to embed it using an iframe, you can also use the following approach:

const iframe = document.getElementById('vncFrame') as HTMLIFrameElement;
const consoleUrl = `https://pve-node-ip:8006/?console=kvm&novnc=1&vmid=${vmid}&vmname=${vmName}&node=${node}&resize=scale&cmd=`;

const websocketUrl = `wss://pve-node-ip:8006/api2/json/nodes/${node}/qemu/${vmid}/vncwebsocket?port=${port}&vncticket=${encodedTicket}`;

This is correct., you might facing 401 status due to this above websocket request need Cookie in request header., As I making websocket request from javascript in my code., there I am not able to put/send Cookies for websocket request.,Below is correct websocket request URL with pasrams.,

Can Anyone please help me to send Cookie to websocket request or Can we bypass this Cookie authentication for websocket request
