/**

* Example for the ESP32 HTTP(S) Webserver

* IMPORTANT NOTE:

* To run this script, your need to

* 1) Enter your WiFi SSID and PSK below this comment

* 2) Make sure to have certificate data available. You will find a

* shell script and instructions to do so in the library folder

* under extras/

* This script will install an HTTPS Server on your ESP32 with the following

* functionalities:

* - Show simple page on web server root

* - 404 for everything else

// TODO: Configure your WiFi here

#define WIFI_SSID "<your ssid goes here>"

#define WIFI_PSK "<your pre-shared key goes here>"

// Include certificate data (see note above)

#include "cert.h"

#include "private_key.h"

// Binary data for the favicon

#include "favicon.h"

// We will use wifi

#include <WiFi.h>

// Includes for the server

#include <HTTPSServer.hpp>

#include <SSLCert.hpp>

#include <HTTPRequest.hpp>

#include <HTTPResponse.hpp>

// The HTTPS Server comes in a separate namespace. For easier use, include it here.

using namespace httpsserver;

// Create an SSL certificate object from the files included above

SSLCert cert = SSLCert(

example_crt_DER, example_crt_DER_len,

example_key_DER, example_key_DER_len

);

// Create an SSL-enabled server that uses the certificate

// The contstructor takes some more parameters, but we go for default values here.

HTTPSServer secureServer = HTTPSServer(&cert);

// Declare some handler functions for the various URLs on the server

// The signature is always the same for those functions. They get two parameters,

// which are pointers to the request data (read request body, headers, ...) and

// to the response data (write response, set status code, ...)

void handleRoot(HTTPRequest * req, HTTPResponse * res);

void handleFavicon(HTTPRequest * req, HTTPResponse * res);

while (WiFi.status() != WL_CONNECTED) {

Serial.print(".");

delay(500);

}

Serial.print("Connected. IP=");

// For every resource available on the server, we need to create a ResourceNode

// The ResourceNode links URL and HTTP method to a handler function

ResourceNode * nodeFavicon = new ResourceNode("/favicon.ico", "GET", &handleFavicon);

ResourceNode * node404 = new ResourceNode("", "GET", &handle404);

// Add the root node to the server

// The path is ignored for the default node.

void handleRoot(HTTPRequest * req, HTTPResponse * res) {

// Status code is 200 OK by default.

// We want to deliver a simple HTML page, so we send a corresponding 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>");

// Discard request body, if we received any

// We do this, as this is the default node and may also server POST/PUT requests

req->discardRequestBody();

// Set the response status

res->setStatusCode(404);

res->setStatusText("Not Found");

// Set content type of the response

res->setHeader("Content-Type", "text/html");

// Write a tiny HTTP page

res->println("<!DOCTYPE html>");
