Vue 通过@stomp/stompjs建立长链接 无法进入connect回调

<template>
  <div>
    <h1>WebSocket 长连接示例</h1>
    <button @click="startConnection">开始连接</button>
    <button @click="stopSubscription" :disabled="!isConnected">取消订阅</button>
    <button @click="closeConnection" :disabled="!isConnected">关闭连接</button>
    <input v-model="messageToSend" placeholder="输入消息">
    <button @click="sendMessage" :disabled="!isConnected">发送消息</button>
    <div v-if="receivedMessage">
      <h2>收到的消息：</h2>
      <p>{{ receivedMessage }}</p>
    </div>

<script>
import { Stomp } from '@stomp/stompjs';

export default {
  data() {
    return {
      client: null,
      subscription: null,
      url: 'ws://127.0.0.1:9000',

      this.client = Stomp.client(this.url);

      this.client.configure({

        heartbeatIncoming: 10,
        heartbeatOutgoing: 20,

          this.isConnected = true;
          this.subscription = this.client.subscribe(this.topic, (message) => {
            console.log('收到消息', message.body);
            this.receivedMessage = message.body;
          });

          console.log(new Date(), str);
        }
      });

      this.client.activate();
    },
    stopSubscription() {
      if (this.subscription) {
        this.subscription.unsubscribe();
        console.log('取消订阅');
      }
    },
    closeConnection() {
      if (this.client && this.isConnected) {
        this.client.deactivate(() => {
          console.log('关闭连接');
          this.isConnected = false;
        });
      }
    },
    sendMessage() {
      if (this.client && this.isConnected) {
        const message = { text: this.messageToSend };
        this.client.publish({ destination: this.topic, body: JSON.stringify(message) });
        console.log('消息已发送', message);
      } else {
        console.log('WebSocket 未连接');
      }
    },
    handleConnectionError(error) {
      console.error('WebSocket 连接错误', error);
      this.isConnected = false;
    }
  },
};

input {

const WebSocket = require('ws');

// 指定自定义端口号
const PORT = 9000;

const server = new WebSocket.Server({ port: PORT });

server.on('connection', (ws) => {
  console.log('客户端已连接');

  ws.on('message', (message) => {
    console.log(`收到消息: ${message}`);
     
    // 发送响应消息
    ws.send(`服务器收到: ${message}`);
  });

  ws.on('close', () => {
    console.log('客户端已断开连接');
  });

  ws.on('error', (error) => {
    console.log(`WebSocket 错误: ${error}`);
  });
});

console.log(`WebSocket 服务器在 ws://localhost:${PORT} 运行`);

如上分别为前后端代码 点击开始链接 启动后端ws服务 后端控制台提示客户端已连接，但是前端onConnect回调一直无法进入 ，只有debug事件回调正常

目前不确定是否真正建立了链接 希望获取onConnect的回调事件

是版本不同的缘故么，看着跟官方示例不太一样
