Tried a few times with different functions but couldn’t seem to get it working, had to fall back to absolute paths
When oatpp::swagger::Resources tries to load files and it can't find them it prints out the path it's trying to use.
You may try to use it to debug files loading
When the front-end browser sends a message, code=500 is displayed during server parsing.
What is the reason for this? Is there a better solution?
Server-side JSON data structure:
class DataReq: public oatpp::DTO {
DTO_INIT(DataReq, DTO);
DTO_FIELD(oatpp::String, Name);
DTO_FIELD(oatpp::String, Value);
DTO_FIELD(oatpp::List<oatpp::String>, ListValue);
DTO_FIELD(oatpp::String, Enable);
};
class RequestDto: public oatpp::DTO {
DTO_INIT(RequestDto, DTO);
DTO_FIELD(oatpp::String, Com);
DTO_FIELD(oatpp::Object<DataReq>, Data);
};The data structure sent by the front end:
{
"Com":"Set",
"Data":{
"Name":"List",
"Value":"",
"ListValue":[{
"Index":"0",
},{
"Index":"1",
}],
"Enable":""
}
}
Error message received by the front-end:

message=[oatpp::parser::json::Utils::preparseString()]: Error. '"' - expectedListValue field as a list of strings

Hello @kevinbenson1 ,
Hello everyone. Is there a plan to tag a new release of oat++ anytime soon? There are some changes that have been committed since 1.3.0 that I would like to pull into our software. If it will be a while, I will just upgrade to 1.3.0 and add them as patches. In general, is additional testing performed on tagged releases? If not, maybe I will just pull in the latest trunk.
In the nearest two month there will be no new tag.
I suggest taking the latest master.
While we do additional testing on tag-builds, we encourage community to use the latest master and report bugs. - Crowd testing:)

Hello @EnderTheCoder ,
Guys I was trying to use oatpp ADD_CORS()
it didn't seem to work on my reponse
From your screenshot - there is a response from oatpp server withcontent-type: application/json`.
So it worked.
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
