我正在开发一个应用程序,它将探测连接在网络上的ONVIF设备以进行自动发现.根据ONVIF Core规范,Probe消息的SOAP格式为:
<?xml version="1.0" encoding="UTF-8"?>
<e:Envelope xmlns:e="http://www.w3.org/2003/05/soap-envelope"
xmlns:w="http://schemas.xmlsoap.org/ws/2004/08/addressing"
xmlns:d="http://schemas.xmlsoap.org/ws/2005/04/discovery"
xmlns:dn="http://www.onvif.org/ver10/network/wsdl">
<e:Header>
<w:MessageID>uuid:84ede3de-7dec-11d0-c360-f01234567890</w:MessageID>
<w:To e:mustUnderstand="true">urn:schemas-xmlsoap-org:ws:2005:04:discovery</w:To>
<w:Action
a:mustUnderstand="true">http://schemas.xmlsoap.org/ws/2005/04/discovery/Pr
obe</w:Action>
</e:Header>
<e:Body>
<d:Probe>
<d:Types>dn:NetworkVideoTransmitter</d:Types>
</d:Probe>
</e:Body>
</e:Envelope>
如何在WCF中发送此消息以发现onvif deivce？
