I'm trying to do a web-socket connection, but it's not working with
chrome(works in firefox). It might be my own issue, which Is why I did set
this to be a bug. I get this in response:
guacamole.js?compile=false:10040 WebSocket connection to
'ws://localhost:####/********/guacamole/websocket?port=####&password=*******&host=******'
failed: Error during WebSocket handshake: Sent non-empty
'Sec-WebSocket-Protocol' header but no response was received
I've seen people say that I have to set "subprotocol: 'base46', but I'm not
sure where I would set that for the web-socket, as that seems to be created
within guac somewhere.
My current set-up in Grails3/SpringBoot is:
@ServerEndpoint("/guacamole/websocket")
class EndpointConfig extends GuacamoleWebSocketTunnelEndpoint
implements ServletContextListener {
@Override
void contextInitialized(ServletContextEvent sce) {
ServletContext servletContext = sce.servletContext
ServerContainer serverContainer =
servletContext.getAttribute("javax.websocket.server.ServerContainer")
try {
// This is necessary for Grails to add the endpoint in development.
// In production, the endpoint will be added by the @ServerEndpoint
// annotation.
if (Environment.current == Environment.DEVELOPMENT) {
serverContainer.addEndpoint(EndpointConfig)
}
serverContainer.defaultMaxSessionIdleTimeout = 0
} catch (IOException e) {
log.error(e.message, e)
}
}
@Override
void contextDestroyed(ServletContextEvent sce) {
}
@Override
protected GuacamoleTunnel createTunnel(Session session,
javax.websocket.EndpointConfig config) throws GuacamoleException {
// Create our configuration TODO change for security after POC
GuacamoleConfiguration guacConfig = new GuacamoleConfiguration()
guacConfig.setProtocol("vnc")
guacConfig.setParameter("hostname", session.requestParameterMap.host[0])
guacConfig.setParameter("port", session.requestParameterMap.port[0])
guacConfig.setParameter("password",
session.requestParameterMap.password[0])
GuacamoleSocket socket = new ConfiguredGuacamoleSocket(new
InetGuacamoleSocket("localhost", ####), guacConfig)
// Return a new tunnel which uses the connected socket
return new SimpleGuacamoleTunnel(socket)
}
}
I've looked at the sample client, but that is very tightly coupled into
it's own implementation, so I'm not sure if there is something I could take
from it.
Thank you for reading, and any help you might be able to provide
