和 MQTT 一樣，我可以通過 Stomp 使用“#”字符訂閱所有主題嗎？var onConnect = function(frame) {      debug("connected to MQTT");      $('#connect').fadeOut({ duration: 'fast' });      $('#connected').fadeIn();      client.subscribe('#');    };/* ------------------------------ */client.connect(login, passcode, function(frame) {            client.debug("connected to Stomp");client.subscribe('#', function(message) {});});
