保鲜的UPnP不返回操作 [英] Cling UPnP not returning Actions

问题描述

我正在使用的Andr​​oid 保鲜的UPnP 框架连接的UPnP功能的设备。我成功地创造一个设备和浏览在网络中可用的设备。但在网络中的三星电视机中没有返回任何行动的框架。 在这里，我加入了服务细节为RenderingControl

 ＆LT;服务＆GT;
＆LT;的serviceType＆GT;金塔：架构 - 支持UPnP组织：服务：RenderingControl：1＆LT; /的serviceType＆GT;
＆LT;服务ID＆GT;金塔：支持UPnP组织：服务ID：RenderingControl＆LT; /服务ID＆GT;
＆LT; controlURL＆GT; /的UPnP /控制/ RenderingControl1＆LT; / controlURL＆GT;
＆LT;的eventSubURL＆GT; /的UPnP /事件/ RenderingControl1＆LT; /的eventSubURL＆GT;
＆LT; SCPDURL＆GT; RenderingControl1.xml＆LT; / SCPDURL＆GT;
＆LT; /服务＆GT;
 

这是网址获取服务描述符xml文件

 ＆GT; HTTP：//＆LT; IP地址＆gt;：52235 / DMR / SamsungMRDesc.xml
 

但SCPDURL是相对的，我想知道的保鲜框架是否正在寻找

  

的http：//＆LT; IP地址＆gt;：52235 / RenderingControl1.xml

而不是

  

的http：//＆LT; IP地址＆gt;：52235 / DMR / RenderingControl1.xml

时它正在显示的服务保鲜的UPnP没有动作或我在做一些真正愚蠢的原因是什么？

我怎样才能正确地与这样做保鲜的UPnP ？

解决方案

只是一个事先澄清：网址 * SamsungMRDesc.xml 是设备描述符，不是服务描述符的是你写的吧？

在＆LT; SCPDURL＆GT; 每UPnP的规范是相对于在该设备描述所在的URL。所以，是的，正确的绝对SCPDURL是第二个。但我会如果有保鲜真的如此严重的错误非常吃惊。因此，要提供一些理论：

1. 你是什么意思显示在保鲜的UPnP没有动作？那是一些现有的示例应用程序或code？攀附本身不提供任何GUI。可能会有在code一个错误？
2. 你真的确认有关的设备描述符的URL（SamsungMRDesc）？它是手动到达，即通过简单的复制和;粘贴URL到Web浏览器
3. 您所看到的，如果你复制和;粘贴SCPDURL到网络浏览器？是否有一些＆lt;作用＆GT; 下的节点＆LT;行为列表＆GT;
4. 您是否尝试过与查询的DeviceSpy三星电视从英特尔开发工具 ？你可以看到一个其他UPnP协议栈所看到的，除了保鲜。此外，您还可以在设备节点上单击鼠标右键，以及服务节点，看到DeviceSpy查找说明。
5. 作为最后的实例，就可以嗅出什么东西被来回传送使用Wireshark。先从设置Wireshark的IP过滤器，以您的三星电视的地址。

4理论和5显然需要连接到相同的网络电视（和你的Andr​​oid）的PC。

I am using cling UPnP framework in android to connect to UPnP enabled device. I am successful in creating a device and browsing for available devices in the network. But for the samsung TV in the network the framework in not returning any actions. Here I am adding the service detail for the RenderingControl

<service>
<serviceType>urn:schemas-upnp-org:service:RenderingControl:1</serviceType>
<serviceId>urn:upnp-org:serviceId:RenderingControl</serviceId>
<controlURL>/upnp/control/RenderingControl1</controlURL>
<eventSubURL>/upnp/event/RenderingControl1</eventSubURL>
<SCPDURL>RenderingControl1.xml</SCPDURL>
</service>

This is the url for fetching the service descriptor xml file

> http://<ip address>:52235/dmr/SamsungMRDesc.xml

But the SCPDURL is relative and I am wondering whether the cling framework is searching for

http://<ip address>:52235/RenderingControl1.xml

instead of

http://<ip address>:52235/dmr/RenderingControl1.xml

Is it the reason for no actions being displayed for the services in cling UPnP or am I doing something really stupid?

How can I properly do this with cling UPnP?

解决方案

Just a clarification beforehand: the URL *SamsungMRDesc.xml is a device descriptor, not a service descriptor as you've written, right?

The <SCPDURL> per UPnP spec is "relative to the URL at which the device description is located". So yes, the correct absolute SCPDURL is the second one. But i would be highly surprised if there was really such severe bug in Cling. So to offer some theories:

1. What do you mean by "no actions being displayed in Cling UPnP" ? Is that some existing example app or your code? Cling itself does not provide any GUI. Might there be a bug in that code?
2. Are you absolutely sure about the device descriptor URL (SamsungMRDesc)? Is it reachable manually, i.e. by simply copy&pasting the URL into web browser?
3. What you see if you copy&paste the SCPDURL into web browser? Are there some <action> nodes under <actionList>?
4. Have you tried to query your Samsung TV with DeviceSpy from Intel Developer Tools ? You can see what an other UPnP stack sees, besides Cling. Furthermore, you can right-click on a Device node as well as Service node and see where DeviceSpy looks for the descriptions.
5. As a last instance, you can sniff what's being sent back and forth with Wireshark. Start with setting Wireshark IP filter to the address of your Samsung TV.

Theories 4 and 5 obviously require a PC connected to the same network as the TV (and your Android).
