【问题描述】：

我如何在 node.js 中创建一个 websocket stomp 客户端 (WebSocketStompClient)，就像我在 java 中使用这行代码一样。

WebSocketStompClient stompClient = new WebSocketStompClient(new SockJsClient(createTransportClient()));
    stompClient.setMessageConverter(new MappingJackson2MessageConverter());

    StompSession stompSession = stompClient.connect("ws://localhost:8081/stomp", new StompSessionHandlerAdapter() {
    }).get(10, SECONDS);

我已经在 node.js 中尝试了几个 websocket 项目，但它们都不起作用

【解决方案1】：

我明白了！这适用于 Spring boot websocket + stomp + StockJS

var Stomp = require('stompjs')
var SockJS = require('sockjs-client')
var url = 'http://localhost:8081/stomp';
console.log('connecting to '+url);
var sock= new SockJS(url);
var stompClient = Stomp.over(sock);


var callback = function(message){
  console.log('received message: '+message);
};


sock.onopen = function() {
  console.log('open');

};

sock.onmessage = function(e) {
  console.log('message', e.data);
  sock.close();
};

sock.onclose = function() {
  console.log('close');
};


stompClient.connect({},function (frame) {
  stompClient.subscribe('/user/queue/reply', callback);
  stompClient.send('/app/chat/este/es/el/chat/java/*/java/*',{},'{"name":"from nodejs"}');
});
