vue如何优雅的使用全局WebSocket

//utils/globalWs.js
import { Notification } from 'element-ui'  //引入ui组件, 作消息通知
import router from '@/router/routers'  //引入router, 作页面跳转
import store from '@/store'  //引入store, 作聊天消息存储

export default {
  ws: {},
  //发送ws方法
  sendWs: function(data) {
    console.log(data, '发送的消息')
    this.ws.send(JSON.stringify(data))
  },
  //初始化ws
  initWs: function() {
    const that = this
    if ('WebSocket' in window) {
      // 打开一个 web socket
      const ws = new WebSocket(process.env.VUE_APP_WS_API)

      that.ws = ws
      ws.onopen = function() {
        console.log('ws.onopen')
        // Web Socket 已连接上，使用 that.sendWs() 方法发送数据, 例如
        that.sendWs({name:'张三'})
      }
      ws.onmessage = function(evt) {
        console.log('全局数据已接收...', evt.data)
        var receivedData = JSON.parse(evt.data)
        
        // 添加聊天记录代码
        // store.commit('ADD_CALL_LOG', data)

        //新消息通知
        //Notification.info({
        //  title: '消息',
        //  message: '您有一条新的消息',
        //  onClick: () => {
        //     if (router.currentRoute.fullPath != '/airobot/chat') {
        //      页面跳转
        //      router.push('/airobot/chat')
        //    }
        //  }
        //})
      }
    }
    // 异常断开重连(2023.4.12更新)
    ws.onerror = function(err) {
        console.log('websocket 断开: ' + err, ws.readyState)
        if (ws.readyState != 0) {
          setTimeout(() => {
            that.initWs()
          }, 1000)
        }
      }
  },
  //断开socked方法
  closeWs: function() {
    // 关闭定时器
    console.log('关闭定时器')
    clearInterval(this.heartbeat)
    console.log('关闭ws')
    this.ws.close()
  }
}

//main.js
import globalWs from './utils/globalWs.js'
Vue.prototype.$globalWs = globalWs

import globalWs from '@/utils/globalWs.js'
globalWs.initWs()

this.globalWs.initWs()
