微耕门禁跨网段搜索代理
解决UDP无法跨网段时的控制器搜索问题
思路：
- 配置已知的搜索指令
- 配置已知的待搜索网段
- 定时使用HTTP发送指令至IP，收集并缓存收到的应答
- 监听收到UDP搜索指令，将未超时的缓存作为应答返回
- 与Http2UDP结合使用，可以实现广播包的返回
注：HTTP2UDP用法
- 设备在A网，Http2UDP在A网，可UDP,业务程序在B网（或互联网），连接http2udp发广播包，返回收到的所有广播包
- 设备在A网，Http2UDP在A网，可UDP,业务程序在B网（或互联网），连接http2udp发UDP包，返回收到的UDP包
- 设备在C网，Http2UDP在A网，不可UDP,先在A网运行ScanProxy进行数据包缓存,业务程序在B网（或互联网），连接http2udp发广播包，ScanProxy返回收到的所有广播包
