使用 gsoap c++​​ 的 Onvif 服务器 WS 发现

问题描述

我一直在努力使 ws-discovery 正常工作。我参考了@mpromonet 的代码 并使用以下选项生成了类

wsdl2h.exe -O4 -P -d -t typemap.dat -o onvif.h ./ws-discovery.wsdl ./remotediscovery.wsdl ./devicemgmt.wsdl ./search.wsdl ./replay.wsdl . /media.wsdl ./media2.wsdl

soapcpp2.exe -2 -LTS -i -x -d ./onvifgen -I./gsoap/gsoap-2.8.109/gsoap/import/;./gsoap/gsoap-2.8.109/gsoap/onvif.

我在 Onvif 设备测试工具 v20.06 中发现设备时遇到问题，但通过 Onvif 设备管理器 v2.2.250 可以实现相同的发现。设备测试工具在探测时不会发现并返回设备类型为 Not NetworkVideoTransmitter。>

任何人都可以帮忙。我附上了一个可重现的例子。 谢谢

对此类的调用是从示例 MFC 对话框进行的。

UINT Rundiscovery(LPVOID pParam)
{
    COnvifdiscoveryDlg* pDlg = (COnvifdiscoveryDlg*)pParam;
    pDlg->m_objdiscover.Rundiscovery();
    return 0;
}

//OnOK
AfxBeginThread(Rundiscovery,this);

//object declaration
CDevicediscovery m_objdiscover;

当通过 Onvif 设备测试工具发现时，wsdd_event_probe 永远不会被调用。 这是一个服务器实现，所有服务都内置在一个静态链接库中。 请任何人都可以帮忙。 附注此代码是从 https://github.com/mpromonet/v4l2onvif 复制和修改的。
