STOMP - SSL - JavaScript

Updated on 20 Sep 2023

To retrieve a message and display it, we’ll use JavaScript. First lets download the stomp client. This comes from the excellent Stomp over Websocket website.

If you recall from an earlier section we did this

sudo rabbitmq-diagnostics listeners

Notice that https/web-stomp protocol uses port 15673. This is inline with how we set up the rabbitmq.conf file earlier.

Line 8 is where we make a change from our previous JavaScript.

var url = "wss://localhost:15673/ws"
$(document).ready(function() {
    //--this is using rabbitmq

    //this works
    var url = "wss://localhost:15673/ws";
    var client = Stomp.client(url);

    //client.heartbeat.incoming = 0;
    //client.heartbeat.outgoing = 0;

    connect_callback = function() {
        // called after the client is connected and 
        // authenticated to the STOMP server
        client.subscribe("/queue/q1", stomp_callback); 
    error_callback = function(error) {
    // display the error's message header:

    //user, pass, connect_event, error_event, host  (host does not work with command line stomp from python)
    //client.connect('demo_user', 'demo_pass', connect_callback, error_callback, 'demo_host');

    var headers = {
        login: 'demo_user',
        passcode: 'demo_pass',
        host: 'demo_host',
        // additional header
        'client-id': 'my-client-id'
      client.connect(headers, connect_callback, error_callback);

    //-- called when the client receives a STOMP message from the server
    function stomp_callback(message)
        if(message.body) {
            //--avoid double up of information displayed.
            var text = message.body;
            text = text.substring(text.indexOf("\r") + 1);

            //--convert the newline character to <br />
            html = text.split("\n").join("<br />");



    //--button send...  (WORKS)
        //--send a message
                   "Hello from my webpage, STOMP\n");



Now lets build a webpage. The important parts are

  • stomp.js → we got that from the stomp client link above.
  • myStomp.js → that is the JavaScript code above.

Send a message

Lets send a message.

./ "hello world from Python -ssl"

And check it in the queue.

rabbitmqadmin get queue=q1 --vhost=demo_host -u guest -p guest

And finally see it in the web-browser
