vue使用 封装websocket心跳包

这套代码可以拿过去直接用 一些注意我会在下面代码中加上注释:

谢谢支持

核心代码

 //这里需要引入vuex
 import store from './store';

 let wsConnection = {
   $ws: null,
   lockReturn: false,
   timeout: 60 * 1000 * 5,
   timeoutObj: null,
   timeoutNum: null,
   serverTimeoutObj: null,
   //初始化webSocket长连接
   initWebSocket: function () {
     let corpId = localStorage.getItem('corpId');
     let name = localStorage.getItem('username');
     this.$ws = new WebSocket(wsurl);//写入地址 这里的地址可以在initWebSocket方法加入参数
     this.$ws.onopen = this.wsOpen;
     this.$ws.onclose = this.wsClose;
     this.$ws.onmessage = this.wsMsg;
     this.$ws.onerror = this.wsError;
   },
   //打开websocket
   wsOpen: function (e) {
     //开始websocket心跳
     wsConnection.startWsHeartbeat();
     console.log('ws success')
   },
   wsClose: function (e) {
     console.log(e, 'ws close')
   },
   wsMsg: function (msg) {
     //每次接收到服务端消息后 重置websocket心跳
     wsConnection.resetHeartbeat();
     //服务端发送来的消息存到vuex
     store.commit('web_socket_msg', msg)
   },
   wsError: function (err) {
     console.log(err, 'ws error');
     wsConnection.reconnect()
   },
   //重启websocket
   reconnect: function () {
     let _this = this;
     if (_this.lockReturn) {
       return;
     }
     _this.lockReturn = true;
     _this.timeoutNum && clearTimeout(_this.timeoutNum);
     _this.timeoutNum = setTimeout(function () {
       _this.initWebSocket();
       _this.lockReturn = false;
     }, 3000);
   },
   startWsHeartbeat: function () {
     let _this = this;
     _this.timeoutObj && clearTimeout(_this.timeoutObj);
     _this.serverTimeoutObj && clearTimeout(_this.serverTimeoutObj);
     _this.timeoutObj = setInterval(function () {
       //判断websocket当前状态
       if (_this.$ws.readyState != 1) {
         _this.reconnect()
       }
     }, _this.timeout);
   },
   //重置websocket心跳
   resetHeartbeat: function () {
     let _this = this;
     clearTimeout(_this.timeoutObj);
     clearTimeout(_this.serverTimeoutObj);
     _this.startWsHeartbeat()
   }
 };

 //抛出websocket对象
 export default wsConnection

websocket方法调用

 //在main.js引入
 import wsConnection from './vuex/wsStore'
 //挂载vue原型链
 Vue.prototype.$setWs = wsConnection;

 //在使用地方调用
  $this.$setWs.initWebSocket();

 //在需要使用服务端推送过来的消息时
 //在computed方法声明
 getWsMsg() {
    //在核心代码接收到的服务端信息存储到vuex的属性
     return this.$store.state.webSocketMsg
 }
 //在watch方法   监听  getWsMsg
  getWsMsg: function (data, val) {
    console.log(data);
    //.......
 }
