C语言 UPNP - 在设备和服务之间绑定 (miniupnp)

Question

我正在使用在我的路由器上运行的miniupnp SW软件包。为了列出我的LAN网络上所有可用的设备/服务，我使用了"listdevice"应用程序，它基本上查询miniupnpc以发现所有设备/服务，然后打印出来。

有人可以解释一下我如何理解，哪个服务属于每个设备？

请参阅下面的示例表：

Answer 1

对于这种情况，响应实际上会为您解决问题。

每台设备将始终跟着他的服务，因此如上表所示，设备可能不提供任何服务，例如：

5: urn:schemas-upnp-org:device:WANConnectionDevice:1
http://192.168.1.1:5000/rootDesc.xml
uuid:63ce4f39-1485-4bd6-ba33-bb1ec09dc1c1::urn:schemas-upnp-org:device:WANConnectionDevice:1

或者可以提供多种服务，例如：

6: urn:schemas-upnp-org:device:WANDevice:1         
http://192.168.1.1:5000/rootDesc.xml
uuid:63ce4f39-1485-4bd6-ba33-bb1ec09dc1c0::urn:schemas-upnp-org:device:WANDevice:1
7: urn:schemas-upnp-org:service:WANIPConnection:1  
http://192.168.1.1:5000/rootDesc.xml
uuid:63ce4f39-1485-4bd6-ba33-bb1ec09dc1c1::urn:schemas-upnp-org:service:WANIPConnection:1
8: urn:schemas-upnp-org:service:WANCommonInterfaceConfig:1
http://192.168.1.1:5000/rootDesc.xml
uuid:63ce4f39-1485-4bd6-ba33-bb1ec09dc1c0::urn:schemas-upnp-org:service:WANCommonInterfaceConfig:1
9: urn:schemas-upnp-org:service:WANPPPConnection:1
