Description
I need to register a node callback with a object member function
I created a class to hold all my https request callbacks functions and I want to pass those functions to ResourceNode constructor and register in my server.
Some of my files
https_handler.h
#ifndef HTTPS_HANDLER_H
#define HTTPS_HANDLER_H
#include "Arduino.h"
#include <HTTPSServer.hpp>
#include "SSLCert.hpp"
#include <HTTPRequest.hpp>
#include <HTTPResponse.hpp>
using namespace httpsserver;
class HttpsHandler {
public:
HttpsHandler();
~HttpsHandler();
void root(HTTPRequest * req, HTTPResponse * res);
private:
};
#endifhttps_handler.cpp
#include "https_handler.h"
void HttpsHandler::root(HTTPRequest * req, HTTPResponse * res) {
// We want to deliver an HTML page, so we set the content type
res->setHeader("Content-Type", "text/html");
// The response implements the Print interface, so you can use it just like
// you would write to Serial etc.
res->println("<!DOCTYPE html>");
res->println("<html>");
res->println("<head><title>Hello World!</title></head>");
res->println("<body>");
res->println("<h1>Hello World!</h1>");
res->print("<p>... from your ESP32!</p>");
res->println("</body>");
res->println("</html>");

class MyServer {

HTTPSServer secureServer = HTTPSServer(&cert);

Is it possible to do what I am proposing? how?
I'm a beginner in CPP
thanks in advance
