接下来是如何识别设备了
注释：没有添加注释的节点 建议保持默认值

DMS（MediaServer） 必须包含ContentDirectory 和 ConnectionManager服务
DMP（AVRenderer） 必须包含ConnectionManager、RenderingControl和AVTransport服务
后面的文章主要介绍接口API，不再介绍接口调用和例子
“服务”调用的方法
请求：
注：
1、绿色部分换成服务相应的值
2、Browse为接口名称
3、pararms... 换成接口参数
POST /_urn-schemas-upnp-org-service-ContentDirectory_control HTTP/1.1
HOST: 192.168.0.106:47619
SOAPACTION: "urn:schemas-upnp-org:service:ContentDirectory:1#Browse" //
CONTENT-TYPE: text/xml ; charset="utf-8"
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<u:Browse xmlns:u="urn:schemas-upnp-org:service:ContentDirectory:1">
pararms...
</u:Browse>
</s:Body>
</s:Envelope>
调用例子：
请求：
POST /_urn-schemas-upnp-org-service-ContentDirectory_control HTTP/1.1

<s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<u:Browse xmlns:u="urn:schemas-upnp-org:service:ContentDirectory:1">
<ObjectID>0</ObjectID>
<BrowseFlag>BrowseDirectChildren</BrowseFlag>
<Filter>*</Filter>
<StartingIndex>0</StartingIndex>
<RequestedCount>15</RequestedCount>

</u:Browse>
</s:Body>
</s:Envelope>
响应：

“事件订阅” 调用的方法
客户端请求：
SUBSCRIBE /_urn-schemas-upnp-org-service-ConnectionManager_event HTTP/1.1
NT: upnp:event
TIMEOUT: Second-300
HOST: 192.168.30.14:47187
//CALLBACK 为服务器推给客户端的数据，也就是说客户端需要 启动一个server用于接收
服务器响应：
HTTP/1.1 200 OK
TIMEOUT: Second-300
SID: uuid:0bd467b6-ad65-4873-a9b3-168bf7a987d2-urn:schemas-upnp-org:service:ConnectionManager-1
SERVER: Windows NT/5.0, UPnP/1.0
服务器推送的订阅
服务器推送：
NOTIFY /0bd467b6-ad65-4873-a9b3-168bf7a987d2/urn:schemas-upnp-org:service:ConnectionManager HTTP/1.1
CONTENT-TYPE: text/xml
