How to intercept all http requests on esp?

Question

Arduino

There is esp32 which works in the access point mode on which the server works.
And there is a task to process all requests coming from any url.
The question is how to process all PSOT|GET requests with one function, and in the function see which domain, url the request was made for?

Answer 1

It turned out to process all the urls, but now how can I find out the domain by which I changed it?

#include <WiFi.h>
#include <DNSServer.h>
#include <WebServer.h>

WebServer webServer(80);

const char *ssid = "TEST-123";
const char *password = NULL; // "12345678";

IPAddress apIP(192, 168, 1, 4);
DNSServer dnsServer;

void setup() {
  WiFi.mode(WIFI_AP);
  WiFi.softAP(ssid, password);
  delay(100);
  
  WiFi.softAPConfig(apIP, apIP, IPAddress(255, 255, 255, 0));

  const byte DNS_PORT = 53;
  dnsServer.start(DNS_PORT, "*", apIP);

webServer.onNotFound([]() {
    String message = "Hello World!\n\n";
    message += "URI: ";
    message += webServer.uri();
    Serial.println(webServer.hostHeader());
    webServer.send(200, "text/plain", message);
  });
  webServer.begin();
}

void loop() {
  dnsServer.processNextRequest();
  webServer.handleClient();
}
