How to authenticate user in ONVIF? - c

Question

we have network IP camera that supports ONVIF protocol. When I tried to get its PTZ configuration it gives Auth error. I am implementing this in C. Following are the request and response.
Request:
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
"<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\""

How can I authenticate user? Thanks

Answer 1

those commands which required authentication. Their authentication headers can be added like this.
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-"
"200401-wss-username-token-profile-1.0#PasswordDigest\">"
"%s</wsse:Password><wsse:Nonce>%s</wsse:Nonce>"
"<wsu:Created>%s</wsu:Created></wsse:UsernameToken>"
"</wsse:Security></SOAP-ENV:Header><SOAP-ENV:Body>"
"<tds:GetNodes>"
"</SOAP-ENV:Body></SOAP-ENV:Envelope>",
username, base64EncDigest, nonce_char, time_char);

You can use gSoap with WSSE plugin to generate C++ client proxy from OnVif WDSL that you require.
Do that greatly simplified my work. Here 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));
So no manually creating soap messages. gSOAP generated code takes care of that in lower layer. Of course, it takes mi 2 days to generate working code with wsse support, but still it was probably 10 times faster the to do it manualy. If you are interested in further information you can contact me.
