vue 连接websocket,及5秒之后没有数据,就关闭上一个,重新连接ws

mounted(){
	this.initSocket()
},
methods:{
	initSocket(){
	const ip = '127.0.0.1'
	const port= '8083'
	const username= 'zs'
	let url = `ws://${ip}:${port}/xxx/${username}`
	this.webSocket = new WebSocket(url)
	this.webSocket.onopen = this.webSocketOnOpen
	this.webSocket.onclose = this.webSocketOnClose
	this.webSocket.onmessage = this.webSocketOnMessage
	this.webSocket.onerror = this.webSocketOnError
	// 重置下间隔最新时间
	this.queryForm.time1 =  this.parseTime(new Date())
	this.webSocketResend()
	},
	// 发送数据
	wsSend () {
		let param={name:'张三'}   // 这里可以随意改,反正要string数据类型
		this.webSocket.send(JSON.stringify(param))
	},
	// 接收数据
    wsGetData (data) {
		// 这里出来接收的数据
	},
	// 建立连接成功后的状态
    webSocketOnOpen() {
      console.log('websocket连接成功');
      this.wsSend()
    },
    // webSocketResend重新发送数据-5秒没数据,就更新
	webSocketResend(){
		let skip = 1*5*1000 // 这里间隔多少秒可以改
		let skipTime = 1 *5
		this.timerW = setInterval(()=>{
			// 间隔秒数
			let intervaltime = (new Date().getTime() - new Date(this.queryForm.time1).getTime()) / 1000;
			// 大于5秒还没数据,就需要重连
			if(intervaltime>skipTime){
				// console.log('intervaltime',intervaltime,',skip',skip)
				// console.log('webSocket',this.webSocket.readyState )
				// 重连
				this.webSocketOnClose()
				this.initSocket()
			}
		},skip)
	},
    // 获取到后台消息的事件,操作数据的代码在onmessage中书写
    webSocketOnMessage(res) {
        // res就是后台实时传过来的数据
        // console.log(res, 'webSocketOnMessage');
        let data = JSON.parse(res.data)
        this.wsGetData(data)
          //给后台发送数据

    // 关闭连接
    webSocketOnClose() {
        this.webSocket.close()
        console.log('websocket连接已关闭');
    },
    //连接失败的事件

        // 打印失败的数据
        console.log(res);
