Hi! I am trying to add a login page to my project. It consists of a button that turns on a led when pressed. The problem is that I get 'class WiFiServer' has no member named 'hasHeader'. I can run the "SimpleAuthentification" project from the examples. I am using an ESP8266-01. Any ideas about how can I solve this?
Here is my code:
#include <ESP8266WiFi.h>
#include <WiFiUdp.h>
#include <NTPClient.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
const long utcOffsetInSeconds = 3*3600;
char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
WiFiUDP ntpUDP;
NTPClient timeClient(ntpUDP, "pool.ntp.org", utcOffsetInSeconds);
]
const char* ssid = "ssid";
const char* password = "password";
// Set web server port number to 80
IPAddress ip(127,0,0,53);
IPAddress gateway(192, 168, 0, 1);
IPAddress subnet(255, 255, 255, 0);
WiFiServer server(80);
//Verifica daca e autentificat
bool is_authenticated() {
Serial.println("Enter is_authenticated");
if (server.hasHeader("Cookie")) {
Serial.print("Found cookie: ");
String cookie = server.header("Cookie");
Serial.println(cookie);
if (cookie.indexOf("ESPSESSIONID=1") != -1) {
Serial.println("Authentication Successful");
return true;
}
}
Serial.println("Authentication Failed");
return false;
}
//pagina de logare

Serial.print("Found cookie: ");

Serial.println(cookie);
