[Vala] Libsoup websockets

[Baptiste Gelez <gelezbaptiste openmailbox org>]

Hi everyone,

I'm creating a little app that should be able to communicate with other 
processes (both sending and receiving messages). I first tried to do it 
by launching child processes and sending/receving messages with 
stdout/stdin. But I didn't find how to receive a signal when the child 
process is writing on his stdout.

Then, I tried with websockets. I use the libsoup solution. This is my 
code :

const uint16 port = 8080;

InetAddress address = new InetAddress.loopback (SocketFamily.IPV4);
InetSocketAddress inetaddress = new InetSocketAddress (address, port);

GLib.Socket socket = new GLib.Socket (SocketFamily.IPV4, 
SocketType.STREAM, SocketProtocol.TCP);
socket.bind (inetaddress, true);
socket.listen ();

Server serv = new Server (null);
serv.add_websocket_handler (null, null, null, (server, conn, path, 
client) => {
    conn.message.connect ((type, message) => {
            // receive messages en responds ...
        });
    });
serv.listen_socket (socket, 0);

But when I try to connect to ws://localhost (with JavaScript) it tells 
me "Firefox can't establish a connection with the server at the address 
ws://localhost/."

Valadoc and libsoup C documentation are really poor on Websockets. Can 
you help me to find where is the problem, and how to solve it, please. 
Or at least, giving me some example codes of websocket servers with 
libsoup (I can't find any). Thank you.

Baptiste.
