How to implement a REST API server with POCO C++ Network Library using JSON?
I have been researching about how to do this and all the examples are with text/html. I have tried implement a server api rest using JSON with POCO C++ network libraries but I am not quite sure if it is the correct way to do this.
void MyHandler::handleRequest(HTTPServerRequest& request, HTTPServerResponse& response)
{
response.setStatus(HTTPResponse::HTTP_OK);
response.setContentType("application/json");
std::ostream& ostr = response.send();
string send("true");
ostr << send;
response.setContentLength(send.size());
}
Originally it was implemented for hmtl connections as:
void MyHandler::handleRequest(HTTPServerRequest& request, HTTPServerResponse& response)
{
response.setStatus(HTTPResponse::HTTP_OK);
response.setContentType("text/html");
std::ostream& ostr = response.send();
ostr << "<html><head><title>HTTPTimeServer powered by POCO C++ Libraries</title>";
ostr << "<body><p style=\"text-align: center; font-size: 48px;\">";
ostr << "ConfigHandler";
ostr << "</p></body></html>";
}
Have I done the change correctly or am I missing something??
If anyone knows of a tutorial about how to build an API REST using JSON with POCO C++ Libraries, it will be very much appreciated.
Thanks in advance.

Poco C++ Libraries is a great tool for REST APIs building in modern C++, although, regarding the architecture, there are some design decisions to be made.
I made available on GitHub an example of an API project built in C++ using Poco.
