我是靠谱客的博主受伤马里奥，最近开发中收集的这篇文章主要介绍UPnP 设备描述文件和服务描述文件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

对于一个设备来说，无论是客户端还是服务端，接入网络后，UPnP经历下列过程:

* 获取自己的IP地址，无论是通过dhcp或者手动设置。

* 组播M-SEARCH/*-NOTIFY。

*获取Loacation指定的设备描述文件, 服务描述文件。

*从描述的service/actions/events中选择自己感兴趣的。

UDN -- Unique Device Name

SCPDURL -- Service Control Protocol Document, URL for service description of SOAP methods and state variables.

controlURL -- used for sending SOAP requests.

eventSubURL -- when a state variable is changed, the new state is sent to all programs/devices that have subscribed to the event.

相当于

public interface SwitchPower{

boolean Target = 0;

boolean Status = 0;

void SetTarget(boolean newTargetValue);

boolean GetTarget(void);

boolean GetStatus(void);

}
