      this.beforeunloadTime = new Date().getTime()
    },
    unload() {
      this.unloadTime = new Date().getTime()
      // window.localStorage.setItem('timer', String(this.unloadTime - this.beforeunloadTime))
      // 本地通过localStorage中的数据看出,关闭事件间隔小于1,刷新则大于8
      if (this.unloadTime - this.beforeunloadTime <= 1) {
        // 执行退出登录
        this.logout(true)
      }
    }
