How to authenticate a user in ONVIF?

we have a network IP camera that supports ONVIF protocol. When I tried to get his PTZ configuration, it gives an Auth error. I implement this in C. The following are the request and response.

Inquiry:

"<?xml version=\"1.0\" encoding=\"UTF-8\"?>" 
  "<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\"" 
  "xmlns:tds=\"http://www.onvif.org/ver20/ptz/wsdl\">" 
  "<soap:Body>"
  "<tds:GetNodes/>" 
  "</soap:Body>" 
  "</soap:Envelope>"

those teams that require authentication. Their authentication headers can be added as follows.

 snprintf(postData, sizeof(postData),
          "<?xml version=\"1.0\" encoding=\"utf-8\"?>" 
          "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://www.w3.org/2003/05/soap-envelope\"" 
          "xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401"
          "-wss-wssecurity-secext-1.0.xsd\""  
          "xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-"
          "200401-wss-wssecurity-utility-1.0.xsd\""  
          "xmlns:tds=\"http://www.onvif.org/ver20/ptz/wsdl\">" 
          "<SOAP-ENV:Header><wsse:Security><wsse:UsernameToken>" 
          "<wsse:Username>%s</wsse:Username>" 
          "<wsse:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-"

You can use gSoap with the WSSE plugin to create the C ++ proxy from OnVif WDSL that you need.

This greatly simplified my work. The following is an example of calling GetVideoEncoderConfiguration and reading response.

_media__GetVideoEncoderConfigurations query;
_media__GetVideoEncoderConfigurationsResponse response;

soap_wsse_add_Security(&mediaProxy);
soap_wsse_add_UsernameTokenDigest(&mediaProxy, NULL, m_username.c_str(), m_password.c_str());

if(mediaProxy.GetVideoEncoderConfigurations(&query, &response) == SOAP_OK)
{
    LogSuccess("GetVideoEncoderConfigurations");
    for(auto it = response.Configurations.begin(); it != response.Configurations.end(); ++it)
    {
        onvif__VideoEncoderConfiguration* videoConf = *it;
        log(I3) << "Name= " << videoConf->Name << ", Encoding=" << videoConf->Encoding << ", Resolution=" << videoConf->Resolution->Width << "x" << videoConf->Resolution->Height;
    }
}
else
    LogError("GetVideoEncoderConfigurations", soap_faultdetail(&mediaProxy));
