Websockets和Ec2实例

Question

I'm using NodeJS with express to create a Websocket application with WS on EC2(Ubuntu). I have the following code:

var WebSocketServer = require('ws').Server
  , wss = new WebSocketServer({ port: 8090 });

wss.on('connection', function connection(ws) {
  ws.on('message', function incoming(message) {
    console.log('received: %s', message);
  });

  ws.send('something');
});

Also, I added a "custom tcp rule" to the port 8090 and anywhere(0.0.0.0/0)

After I run: wscat --connect http://myipaddress:8090

I got: error: Error: connect ECONNREFUSED myipaddress:8090

Am I forgetting something in Ec2 Configuration or code?

Greetings

Looks like you are trying to connect using the HTTP protocol. Try running wscat --connect ws://myipaddress:8090 .
