I’m not an English speaker, so I’m using a translator. Please understand.

NVR is being developed using C++. The Onvif protocol must be developed.
For related data research, we are looking at the official Onvif website, ChatGPT, and Gsoap official website and Github.

I have to implement all the search, communication, and control functions, but I have only implemented some of them, or I have difficulty referring to them because the environment is different.

So, I’m building Onvif myself, using WSDL. I’m building using Cmake and I’m having issues with enum and _ds__signature in wsseapi.h.

Is this the right direction I’m in, or should I look for another way?

My code is as follows.

main.cpp

#include "soapDeviceBindingProxy.h"
#include "soapH.h"
#include "wsseapi.h"
#include "wsddapi.h"
#include "soapStub.h"
#include "stdsoap2.h"
#include "namespaces.h"
#include <iostream>
#include <vector>
#include <string>

// ONVIF 장치 검색 함수 
std::vector<std::string> discover_devices()
{
  std::vector<std::string> devices;
  struct soap *soap = soap_new();
  soap_set_namespaces(soap, namespaces);

  struct wsdd__ProbeType req;
  struct __wsdd__ProbeMatches resp;

  soap_default_wsdd__ProbeType(soap, &req);
  req.Scopes = NULL; // Optional
  req.Types = NULL;  // Optional

  if (soap_send___wsdd__Probe(soap, SOAP_MCAST_ADDR, NULL, &req) == SOAP_OK)
  {
    while (soap_recv___wsdd__ProbeMatches(soap, &resp) == SOAP_OK)
    {
      if (resp.wsdd__ProbeMatches->ProbeMatch != NULL)
      {
        for (int i = 0; i < resp.wsdd__ProbeMatches->__sizeProbeMatch; ++i)
        {
          devices.push_back(resp.wsdd__ProbeMatches->ProbeMatch[i].XAddrs);
        }
      }
    }
  }

  soap_destroy(soap);
  soap_end(soap);
  soap_free(soap);

  return devices;
}

int main(int argc, char *argv[])
{
  std::vector<std::string> devices = discover_devices();

  if (devices.empty())
  {
    std::cerr << "No ONVIF devices found!" << std::endl;
    return 1;
  }

  std::cout << "Found ONVIF devices:" << std::endl;
  for (const auto &device : devices)
  {
    std::cout << " - " << device << std::endl;
  }

  // 첫 번째 장치에 연결하여 정보 가져오기 connect
  DeviceBindingProxy device;
  device.soap_endpoint = devices[0].c_str();

  _tds__GetCapabilities request;
  _tds__GetCapabilitiesResponse response;

  if (device.GetCapabilities(device.soap_endpoint, NULL, &request, response) == SOAP_OK)
  {
    std::cout << "GetCapabilities success!" << std::endl;
  }
  else
  {
    device.soap_stream_fault(std::cerr);
  }

  return 0;
}
