Go语言 WebSocket 多连接频繁断开：如何避免连接丢失？

// 通过 websocket 发送字符串
func (d *device) websocketsendstring(str string) bool {
    if !d.online {
        return false
    }
    log.println(d.ws.request().remoteaddr)
    if err := websocket.message.send(d.ws, str); err != nil {
        log.println("设备", d.ws.request().remoteaddr,
            "[",d.ws.request().form.get("id"),"] websocket 发送消息失败：%s", err)
        _ = d.ws.close()
        return false
    }
    return true
}
