Hi everyone,
I have a DTO class which consists of fields with other DTO class and I want to access these fields recursively.
Example DTO class:
class DTOSample : public oatpp::DTO {
DTO_INIT(DTOSample, DTO /* Extends */)
DTO_FIELD(Vector<Object<DTOSampleInner>>, inner);
};
class DTOSampleInner : public oatpp::DTO {
DTO_INIT(DTOSampleInner, DTO /* Extends */)
DTO_FIELD(String, name);
DTO_FIELD(String, value);
};
accessFields(const oatpp::data::mapping::type::DTOWrapper<T> dto) {
auto object = static_cast<oatpp::BaseObject *>(dto.get());
auto fields = dto.getPropertiesList();
for (auto const &field : fields) {
auto value = field->get(object);
// How can access name and value fields of DTOSampleInner
}
}Thanks.
Hello @emrahhisir ,
for (auto const &field : fields) {
auto value = field->get(object);
if(value.getValueType() == oatpp::data::mapping::type::__class::AbstractObject::CLASS_ID.id) {
auto dispatcher = static_cast<const type::__class::AbstractObject::PolymorphicDispatcher*>(baseType->polymorphicDispatcher);
const auto& map = dispatcher->getProperties()->getMap(); // <--- And again you get the properties map
}
}And since you have Vector of objects - you have first access items of the vector

Status::CODE_302 response, the oatpp server should listen on ports 80 and 443. What is the recommended method for doing this ?
Hey @frosk1 ,
thx @oatpp_io_twitter understood. Are there any benchmarks of this http web server vs some other languages like python (gunicorn server, uswgi server, etc.) or go( gin http server) ?
For oatpp 1.1.0 - https://www.techempower.com/benchmarks/#section=data-r21&test=json
Also you may search on github - there must be some repos with benchmarks like this one https://github.com/memen45/server_benchmark
Hello @fabrice.aeschbacher_gitlab ,
I'm looking for a way to redirect http requests (port=80) to my oatpp https server listening on port 443. To be able to send a Status::CODE_302 response, the oatpp server should listen on ports 80 and 443. What is the recommended method for doing this ?
Yes, you have to listen on both ports.
And you have to add Interceptor on port 80 to redirect to 443 - like here https://github.com/oatpp/website/blob/master/server/main/src/SitePath.hpp#L46
How to setup component - you can find here - https://github.com/oatpp/website/blob/master/server/main/src/AppComponent.hpp

Hi Everyone
A client can send a request that requires significant time (minutes) and resources, and then disconnect before the response is ready.
Is there a smart way to detect on I/O level that the connection that initiated the request is closed and pass this information to the request executor?
Hello @yanalex66 ,

Yes, on I/O level it's possible. However, by that moment oatpp had already delegated processing to Endpoint, and oatpp will not terminate that processing until it's finished.
Hello @oatpp_io_twitter
Thanks for your response.
I'll ponder on the idea of WebSocket. A good idea actually but my clients are HTTP ones (at least, for now).
Yes, on I/O level it's possible. However, by that moment oatpp had already delegated processing to Endpoint, and oatpp will not terminate that processing until it's finished.
I'll try then to find a way to signal the endpoint that response is not required and stop the request processing.
