websocket断线重新连接

function connect() {
  websocket.value = new WebSocket(ws.value)
  websocket.value.onopen = () => {
    console.log('ws连接成功')
  }
  websocket.value.onmessage = (e: any) => {
    try {
      mem.value = JSON.parse(e.data)[0]
      list.value = JSON.parse(e.data)[1]
    } catch (err) {
      console.log(e.data)
    }
  }
  websocket.value.onclose = () => {
    console.log('ws连接关闭')
    setTimeout(function () {
      // 执行重连操作，递归终止条件是ws连接成功
      connect()
    }, 2000)
  }
}
onMounted(async () => {
  connect()
})
