I'm trying to use Websocket to remote-control a LG Smart TV (WebOS 4.0) by using JSTVRemote JavaScript library.
It means the LG SmartTV is a websocket server, and my browser is a websocket client. The browser sends commands to control the TV, TV does the job (e.g. Volume Down) and send a response back to the client.
This library uses WebSocket to communicate with TV:
ws = new WebSocket( "wss://192.168.xxx.xxx:3000" ) ;
ws.onopen = function()
ws.onmessage = function( event )
console.log( event ) ;
alert('command successed!')
ws.onclose = function()
logUpdate( "Connection closed." ) ;
ws.send(someCommand);
When I use it in a local HTML file (open it in browser with file://...), It works correctly. The onmessage
event fires and returns the response from TV. Also, the TV does the job of command.
*Chrome, IE and Safari are OK
However, when I use it in a hosted web page (open the same HTML file with http://... or https://...), the onmessage
event does not file and it reports an error with "WebSocket is already in CLOSING or CLOSED state.". Of course, the TV does not do the job of command.
*the connection establishing seems to succeed because the new WebSocket(), ws.onopen() and ws.send() are OK.
I have tried following web server, but they don't work.
- Apache
- IIS
- Web Server of QNAP(a NAS Server)
Does anyone know the reason of it?
