Question

据我所知，没有WSBaseNotification功能的摄像头不支持推式通知（Notify），所以我必须采用拉式方式（CreatePullPointSubscription和PullMessages）。

首先，我从CreatePullPointSubscription获取SubscriptionReference地址，并将其传递给PullMessages中的“To”地址。这已经成功完成了我测试的三个摄像头中的一个但是另一个失败了。

以下是CreatePullPointSubscription的响应示例：

<SOAP-ENV:Header><wsa5:MessageID>urn:uuid:18764990-3fd8-4175-b074-bfdd6816d5a2</
wsa5:MessageID><wsa5:RelatesTo>urn:uuid:1adbe268-c822-eb58-8560-b07639671351</wsa5:RelatesTo><wsa5:To SOAP-
ENV:mustUnderstand="true">http://www.w3.org/2005/08/addressing/anonymous</wsa5:To><wsa5:Action SOAP-
ENV:mustUnderstand="true">http://www.onvif.org/ver10/events/wsdl/EventPortType/
CreatePullPointSubscriptionResponse</wsa5:Action></SOAP-ENV:Header><SOAP-
ENV:Body><tev:CreatePullPointSubscriptionResponse><tev:SubscriptionReference><wsa5:Address>http://172.22.22.35:80/
onvif/device_service?Idx=0</wsa5:Address></tev:SubscriptionReference><wsnt:CurrentTime>2015-11-26T17:05:55Z</
wsnt:CurrentTime><wsnt:TerminationTime>2038-01-19T03:14:07Z</wsnt:TerminationTime></
tev:CreatePullPointSubscriptionResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

和PulMessagesRequest：

<s:Header><wsa:To>http://172.22.22.35:80/onvi /device_service?Idx=0</wsa:To><wsse:Security><wsse:UsernameToken>

<tev:Timeout>PT5S</tev:Timeout><tev:MessageLimit>2</tev:MessageLimit></tev:PullMessages></s:Body></s:Envelope>

和PullMessagesResponse：

<SOAP-ENV:Header><wsa5:To SOAP-ENV:mustUnderstand="true">http://172.22.22.35:80/onvif

来自ONVIF core specs：

9.1.2提取信息

设备应为 CreatePullPointSubscription命令返回的所有SubscriptionManager 端点提供以下PullMessages命令。

因此，您需要从CreatePullPointSubscription中返回的地址中提取消息。填充请求正文中的wsa5:To字段但使用事件服务的URL通常是不够的。

您只发布了肥皂请求的主体而不是头部，因此无法检查您正在使用的网址。
