修改Navbar.vue
const { addNotice } = useNoticeStore();

onMounted(() => {
  nextTick(() => {
    // 这里写入你想在 DOM 更新完成后执行的代码
    let protocol = window.location.protocol === 'https:' ? 'wss://' : 'ws://'
    initWebSocket(protocol + window.location.host + import.meta.env.VITE_APP_BASE_API + "/resource/websocket",addNotice);
  });
});
