我正在尝试从某些 ONVIF 设备获取事件消息。我的代码在 C# 中。

EventPortTypeClient.CreatePullPointSubscription 上的(Axis 相机)设备上返回:

Address.Value: http : / /192.168.8.48/onvif/services
ReferenceParameters.Any.First().OuterXml: <dom0:SubscriptionId xmlns:dom0="http : / /www.axis.com/2009/event">38</dom0:SubscriptionId>

所以我添加了 "To""SubscriptionId" soap header ,并且可以使用 PullPointSubscriptionClient.PullMessages("PT5M", 99, Any , 输出 CurrentTime, 输出 NotificationMessages)

但是对于只返回 Address.Value 的设备,比如:

  • (大华)地址。值:http://192.168.8.243/onvif/Subscription?Idx=57
  • (Siqura)地址。值:
    http://192.168.8.14/onvif/events_service/SubscriptionManager/15000

我只添加了 "To" soap header ,但是 PullPointSubscriptionClient.PullMessages("PT5M", 99, Any, out CurrentTime, out NotificationMessages) 方法给出了一个故障错误。

有什么帮助吗?

解决方案:

System.Xml.XmlElement[] Any = new System.Xml.XmlElement[] { };
System.DateTime CurrentTime;
System.Nullable<System.DateTime> TerminationTime;
List<MessageHeader> lstHeaders = new List<MessageHeader>() { };
var oEventClient = _session.GetEventPortTypeClient();

var oAux1 = oEventClient.CreatePullPointSubscription(
new onvif10_events.FilterType(),
"PT600S",
new onvif10_events.CreatePullPointSubscriptionSubscriptionPolicy(),
ref Any,
out CurrentTime,
out TerminationTime);

if ((oAux1.ReferenceParameters != null) && (oAux1.ReferenceParameters.Any != null))
{
foreach (System.Xml.XmlElement oXml in oAux1.ReferenceParameters.Any)
{
string strName = oXml.LocalName;
string strNS = oXml.NamespaceURI;
string strValue = oXml.InnerXml;

lstHeaders.Add(MessageHeader.CreateHeader(strName, strNS, strValue, true));
}
}

// oAux1.Address.Value -> the proxy endpoint address
// lstHeaders -> headers to add to the SOAP message of the proxy request
var oPullPointSubscriptionClient = _session.GetPullPointSubscriptionClient(oAux1.Address.Value, lstHeaders);
var oSubscriptionManagerClient = _session.GetSubscriptionManagerClient(oAux1.Address.Value, lstHeaders);

do
{
oPullPointSubscriptionClient.PullMessages("PT60S", 1024, Any, out CurrentTime, out NotificationMessages);

foreach (onvif10_events.NotificationMessageHolderType message in NotificationMessages)
{
/// Handle message
}

var oRenewResult = oSubscriptionManagerClient.Renew(new LIB.Cameras.ONVIF_WS.onvif10_events.Renew() { TerminationTime = "PT600S" });

} while (_session != null);

oSubscriptionManagerClient.Unsubscribe(new onvif10_events.Unsubscribe());

最佳答案

好的。“TO”标题将被忽略。PullPointSubscriptionClient 代理端点 URL 是订阅“Address.Value”(而不是“TO”url)。
