后台返回视频名称一样时前端视频不刷新的问题

给视频动态添加不同的名字

name?t = 当前时间，实现方法如下

html

<video :scr="vUrl"></video>

js

formatDate(now) { 
      var year=now.getFullYear(); 
      var month=now.getMonth()+1; 
      var date=now.getDate(); 
      var hour=now.getHours(); 
      var minute=now.getMinutes(); 
      var second=now.getSeconds(); 
      return year+"-"+month+"-"+date+" "+hour+":"+minute+":"+second; 
    },
    change () {
      let timer = this.formatDate(new Date())
      this.vUrl = `./../../static/movie.mp4?t=${timer}`
    }
