如何使用UPnP C＃发送SetAVTransportURI？

我试图发送一个命令到我的电视（索尼Bravia KDL-42W800A）通过UPnP播放视频。我可以使用SSDP发现网络上的所有UPnP设备。以下是来自电视的示例响应：如何使用UPnP C＃发送SetAVTransportURI？

HTTP/1.1 200 OK

从此我已按照位置检索包含电视上更多细节的XML文件。鉴于如下：

使用此信息，如何我可以请求电视播放视频，如果我有链接？我试图基于我在线阅读的内容，并获得了此代码，该代码应该设置AVTransportURI，但它会一直给出错误500内部服务器错误。

private const string SetAvTransportURIXml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + 
                "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\" s:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">" + 
                 "<s:Body>" + 
                  "<u:SetAVTransportURI xmlns:u=\"urn:schemas-upnp-org:service:AVTransport:1\">" + 
                   "<InstanceID>0</InstanceID>" + 
                   "<CurrentURI>{0}</CurrentURI>" + 
                   "<CurrentURIMetaData></CurrentURIMetaData>" + 
                  "</u:SetAVTransportURI>" + 
                 "</s:Body>" + 
                "</s:Envelope>"; 

    public void PlayVideo(string videoLink) 
    { 
     byte[] bytes; 
     bytes = Encoding.UTF8.GetBytes(String.Format(SetAvTransportURIXml, videoLink)); 

     HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://192.168.1.11:52323/upnp/control/AVTransport"); 
     request.Headers.Add("SOAPAction", "\"urn:schemas-upnp-org:service:AVTransport:1#SetAVTransportURI\""); 
     request.ContentType = "text/xml; encoding=\"utf-8\""; 
     request.ContentLength = bytes.Length; 
     request.Method = "POST"; 
     Stream requestStream = request.GetRequestStream(); 
     requestStream.Write(bytes, 0, bytes.Length); 
     requestStream.Flush(); 
     requestStream.Close(); 
     var response = (HttpWebResponse) request.GetResponse(); 
     if (response.StatusCode == HttpStatusCode.OK) 
     { 
      Stream responseStream = response.GetResponseStream(); 
      if (responseStream == null) return; 
      string responseStr = new StreamReader(responseStream).ReadToEnd(); 
      Console.WriteLine(responseStr); 
     } 
    }

任何帮助，将不胜感激，谢谢。

尝试在CurrentURIMetaData参数中添加一些DIDL-Lite元数据。我的LG电视拒绝播放任何内容，如果我只是将该字段留空即可。

例如，对于我下面的作品（当然这需要嵌入外部XML结构时进行转义）：

<?xml version="1.0"?> 
<DIDL-Lite xmlns="urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/" xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sec="http://www.sec.co.kr/"> 
<item id="f-0" parentID="0" restricted="0"> 
    <dc:title>Video</dc:title> 
    <dc:creator>Anonymous</dc:creator> 
    <upnp:class>object.item.videoItem</upnp:class> 
    <res protocolInfo="http-get:*:video/mp4:DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=01700000000000000000000000000000">{0}</res> 
</item> 
</DIDL-Lite>

也有可能需要有在HTTP响应一些特殊的头电视的媒体请求（在您提供的URL处）。我的LG电视拒绝播放，除非媒体文件的响应具有如下头（区分大小写BTW！）：

contentFeatures.dlna.org: DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=01700000000000000000000000000000 
transferMode.dlna.org: Streaming

有很多事情实现的UPnP/DLNA时可能出错。如果有任何电视不喜欢的东西，它会拒绝接受它。错误消息可能相当不确定。需要大量的测试迭代来确定如何强制不同的DLNA设备实现协作。市场上的许多/大部分电视设备仅实现规格的一小部分。以他们自己的方式。

在Github代码搜索中搜索SetAVTransportURI等有助于弄清楚其他人是如何实现这些功能的。

感谢您的答复，我已经到了舞台现在在哪里可以投射到我的XBox One（通过添加元数据），但是在Sony上它执行SetAVTransportURI并且获得了200 OK响应，然后在电视上加载它时表示播放不可用。这可能与您所讨论的http响应头有关吗？ – 2015-03-20 03:16:28

是的，这很可能取决于媒体请求HTTP响应头（如果您已验证设备实际发送HTTP请求并获得200 OK响应）。 – snap 2015-03-20 20:01:19

我正在为我的索尼BRAVIA KDL-40EX505编码，并有同样的问题。

192.168.0.102是我的电脑和服务器的音乐文件。 192.168.0.10是索尼电视。

当我做setAVTransportURI，会发生以下情况：

以下POST被发送到TV

POST /upnp/control/AVTransport HTTP/1.1 
Host: 192.168.0.10:52323 
Connection: keep-alive 
Content-Length: 442

<?xml version="1.0" encoding="utf-8" standalone="yes"?> 
<s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> 
    <s:Body>

     <CurrentURIMetaData></CurrentURIMetaData> 
     </u:SetAVTransportURI> 
    </s:Body> 
</s:Envelope>

电视sents HEAD请求以从上方的POST在CurrentURI指定的URL ：

HEAD /music.php?f=geradeaus HTTP/1.1 
getcontentFeatures.dlna.org: 1 
X-AV-Physical-Unit-Info: pa="BRAVIA KDL-40EX505"; 
X-AV-Client-Info: av="5.0"; cn="Sony Corporation"; mn="BRAVIA KDL-40EX505"; mv="1.7"; 
Host: 192.168.0.102:80

用于头部请求答案是：

HTTP/1.1 200 OK 
Date: Sat, 05 Mar 2016 20:58:58 GMT 
Server: Apache/2.4.9 (Win64) PHP/5.5.12 
X-Powered-By: PHP/5.5.12 
Content-Length: 9622288 
transferMode.dlna.org: Streaming 
Accept-Ranges: bytes 
Cache-Control: no-cache 
contentFeatures.dlna.org: DLNA.ORG_PN=MP3;DLNA.ORG_OP=01;DLNA.ORG_FLAGS=01700000000000000000000000000000 
Content-Type: audio/mpeg

如果一切正常，电视会以200 OK响应第一个POST请求，否则会出现500内部服务器错误。

结果

所以，对于索尼BRAVIA KDL-40EX505启用

transferMode.dlna.org: Streaming

和

contentFeatures.dlna.org: DLNA.ORG_PN=MP3;DLNA.ORG_OP=01;DLNA.ORG_FLAGS=01700000000000000000000000000000

在HEADER请求到音频或视频的响应是很重要的文件。 我这样做，有一个php文件：

<?php 
    $file = $_GET['f'].'.mp3'; 

    header('Content-Length: '.filesize($file)); 
    header('Content-Type: audio/mpeg'); 
    header('transferMode.dlna.org: Streaming'); 
    header('Accept-Ranges: bytes'); 
    header('Cache-Control: no-cache'); 
    header('contentFeatures.dlna.org: DLNA.ORG_PN=MP3;DLNA.ORG_OP=01;DLNA.ORG_FLAGS=01700000000000000000000000000000'); 

    fpassthru(fopen($file, 'rb')); 
    exit; 
?>

这是通过192.168.0.102:80/music.php?f=geradeaus调用，并返回geradeaus.mp3

找出contentFeatures.dlna.org字符串

我用Android的BubbleUPnP（你必须找到一个适合你的UPnP播放器）来播放音乐文件。之后，我打开Cling Workbench（http://4thline.org/projects/cling/workbench/）选择我的电视机，在树形视图中选择AVTransport和“使用服务”按钮。通过BubbleUPnP播放的文件的URI显示在“当前URI”下。 然后我通过WireShark发现的HEADER对这个URI进行了HEAD调用（重要的是getcontentFeatures.dlna.org，X-AV-Physical-Unit-Info和X-AV-Client-Info，你也可以发送一个http GET to yourTV：52323/upnp/control/AVTransport，而不是使用WireShark，它会在响应头中返回X-AV-Physical-Unit-Info和X-AV-Client-Info。

HEAD调用BubbleUPnP在Android：

HEAD /external/audio/media/8588.mp3 HTTP/1.1 
Host: 192.168.0.12:57645 
Connection: keep-alive 
Cache-Control: no-cache

User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.116 Safari/537.36
