How to make a https Server Arduino-ESP32

Postby Pyshco » Wed Jul 26, 2017 3:35 pm

I already have a http server on my ESP32, now, i need to know how to transform that http into a https server + a little introduction to MQTT exactly for arduino-ESP32. Do i need "<PubSubClient.h>" ? if i need it, how can i use it on this code?

CODE HERE:

Code: Select all


/*Using the ESP-WROOM-32*/
/*Auto-refresh bult into the page*/

#include <WiFi.h>

const char* ssid     = "CLAROQNK37";
const char* password = "9j98g4NuEaq496Yk";

WiFiServer server(80);

const int analogPin = 32;  // Analog input pin , ours is connected to YL-83
int sensorValue = 0;

//Analog ADC read
//4095 => 3.3
// ADC * 3.3 / 4095 = v


void setup()
{
    Serial.begin(115200);    // Baud Rate
    pinMode(5, OUTPUT);      // Green LED
    pinMode(4, OUTPUT);      // Yellow LED
    pinMode(12,OUTPUT);      // Buzzer
    delay(10);
    
    // We start by connecting to a WiFi network
    Serial.println();
    Serial.println();
    Serial.print("Connecting to ");
    Serial.println(ssid);
    WiFi.begin(ssid, password);
    while (WiFi.status() != WL_CONNECTED) 
    {
        delay(100);
        Serial.print(".");
    }
    Serial.println("");
    Serial.println("WiFi connected.");
    Serial.println("IP address: ");
    Serial.println(WiFi.localIP());
    server.begin();
}

int value = 0;

void loop()
{
 WiFiClient client = server.available();   // listen for incoming clients

  if (client)                                // if you get a client,
  {                             
    
    Serial.println("New Client.");           // print a message out the serial port
    
    String currentLine = "";                // make a String to hold incoming data from the client
    
    while (client.connected())              // loop while the client's connected
    {            
      
      if (client.available())               // if there's bytes to read from the client,
      {             
        
        char c = client.read();             // read a byte, then
        
        Serial.write(c);                    // print it out the serial monitor
        //
        if (c == '\n')                      // if the byte is a newline character
        {                    

          // if the current line is blank, you got two newline characters in a row.
          // that's the end of the client HTTP request, so send a response:
          //
          if (currentLine.length() == 0) 
          {
            // HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
            // and a content-type so the client knows what's coming, then a blank line:
            client.println("HTTP/1.1 200 OK");
            client.println("Content-type:text/html");
            client.println();
            
            // the content of the HTTP response follows the header:
