Send custom headers

[csoni111]

How to send custom headers from the java client as mentioned here in the docs?

We don't have extraHeaders option for Java client, but you can do the same thing like https://github.com/socketio/engine.io-client-java#accessing-http-headers

@nkzawa I cannot get this code works,

private Socket mSocket;
{
try {
IO.Options opts = new IO.Options();
mSocket = IO.socket(socket_url, opts);
mSocket.io().on(Manager.EVENT_TRANSPORT, new Emitter.Listener() {
@OverRide
public void call(Object... args) {

            Transport transport = (Transport)args[0];
            transport.on(Transport.EVENT_REQUEST_HEADERS, new Emitter.Listener() {
                @Override
                public void call(Object... args) {
                    @SuppressWarnings("unchecked")
                    Map<String, List<String>> headers = (Map<String, List<String>>)args[0];
                    // modify request headers
                    headers.put("x-user-id", Arrays.asList("5B59F68B7B7811E88C3E52964BF487E4"));
                }
            }).on(Transport.EVENT_RESPONSE_HEADERS, new Emitter.Listener() {
                @Override
                public void call(Object... args) {
                }
            });
        }
    });

} catch (URISyntaxException e) {}

}
