请教如何使用node.js创建socket ssl链接

var sys = require(sys),
ws = require(./ws);

ws.createServer(function (websocket) {
websocket.addListener(connect, function (resource) {
// emitted after handshake
sys.debug(connect: + resource);

// server closes connection after 10s, will also get close event
setTimeout(websocket.end, 10 * 1000);
}).addListener(data, function (data) {
// handle incoming data
sys.debug(data);

// send data to client
websocket.write(Thanks!);
}).addListener(close, function () {
// emitted when server or client closes connection
sys.debug(close);
});
}).listen(8080);
