ESP8266WebServer instance to child olbject

Hello everybody,

I’m writting a project in c++ for an ESP8266 with objects.
I create a class WebServer wich create ESP8266WebServer object. The idea is to create classes with function Routing() and private handle function in this classes.

Here exemple :

WebServer.h

#ifndef DEF_WEBSERVER
#define DEF_WEBSERVER

#include <Arduino.h>
#include <ESP8266WebServer.h>

class WebServer {
    public:
        WebServer(void);
        void setup();
        void loop();
    private:
        ESP8266WebServer server;
        void ServerRouting();
        void RootRoute();
        void handleNotFound();

};

#endif

WebServer.cpp

#include <Arduino.h>
#include <ESP8266WebServer.h>
#include "WebServer.h"

#define WEBPORT 80

WebServer::WebServer() : server(WEBPORT) {}

void WebServer::setup() {
    WebServer::ServerRouting();
    WebServer::server.onNotFound(std::bind(&WebServer::handleNotFound, this));
    WebServer::server.begin();
    Serial.println("HTTP server started");
}

void WebServer::loop(){
    WebServer::server.handleClient();
}

void WebServer::ServerRouting() {
    WebServer::server.on("/", HTTP_GET, std::bind(&WebServer::RootRoute, this));
    // Sub classes
    // MyClass.ServerRouting();
}

void WebServer::RootRoute() {
    WebServer::server.send(200, F("text/html"),F("Your are not allow to be here, get out now !"));
}

// Manage not found URL
void WebServer::handleNotFound() {
  String message = "File Not Found\n\n";
  message += "URI: ";
  message += server.uri();
  message += "\nMethod: ";
  message += (server.method() == HTTP_GET) ? "GET" : "POST";
  message += "\nArguments: ";
  message += server.args();
  message += "\n";
  for (uint8_t i = 0; i < server.args(); i++) {
    message += " " + server.argName(i) + ": " + server.arg(i) + "\n";
  }
  server.send(404, "text/plain", message);
}

This code works perfectly.
I want to create MyClass :
MyClass.h

#ifndef DEF_MYCLASS
#define DEF_MYCLASS

#include <Arduino.h>
#include "WebServer.h"
#include <ESP8266WebServer.h>

class MyClass {
    public:
        MyClass(ESP8266WebServer& server) {srv = &server; }
        void Routing();
    
    private:
        ESP8266WebServer* srv;
        void getData();
        void setData();
};

#endif

MyClass.cpp

#include <Arduino.h>
#include <ESP8266WebServer.h>
#include <ArduinoJson.h>
#include "MyClass.h"

bool isOn = false;

void MyClass::Routing(){
    this->srv.on(F("/mylight"), HTTP_GET, std::bind(&MyClass::getData, this));
}

void MyClass::getData(){
   // Function to send JSON
}

void MyClass::setData(){
    // Function to set light state
}

But I can’t pass ESP8266WebServer server object to MyClass.
I got this kind of messages :

src\MyClass.cpp: In member function 'void MyClass::Routing()':
src\MyClass.cpp:9:15: error: request for member 'on' in '((MyClass*)this)->MyClass::srv', which is of pointer type 'ESP8266WebServer* {aka esp8266webserver::ESP8266WebServerTemplate<WiFiServer>*}' (maybe you meant to use '->' ?)
     this->srv.on(F("/mylight"), HTTP_GET, std::bind(&MyClass::getData, this));
               ^
*** [.pio\build\esp12e\src\MyClass.cpp.o] Error 1

Can you help me please ?

please use CODE tags, not QUOTE

you define your instance variable as a pointerESP8266WebServer* srv;you should just save the reference as this is what you pass to your constructor

MyClass(ESP8266WebServer& server) {srv = &server; }
