Login to a https webserver with username and password

Projects Programming

Hi everybody, this is my first post, so I hope I'm doing the right moves on the forum !
I'm quite new about Arduino and I'm working on a "classic" project, but with a issues that I didn't solve.
I use a Arduino Uno WIFI Rev 2 to connect to a wifi and send data by using POST request to a webserver. I used WifiNINA and ArduinoJSON.
The problem is: I never entered inside the IF after client.connectSSL, because by using a browser I need to login with username and password in a classic login page...but I don't find working solutions with Arduino.
The code that I'm using is the following:

#include <WiFiNINA.h>
#include <ArduinoJson.h>
#include <SPI.h>


char ssid[] = "XXXXXXXXXXXXXXXXXX";
char pass[] = "XXXXXXXXXXXXXXXXXX";

int status = WL_IDLE_STATUS;
DynamicJsonDocument doc(1024); // 
char server[] = "https://XXXXXXXXXXXXX";


WiFiClient client;


void setup() {

  Serial.begin(9600);

  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to Network named: ");
    Serial.println(ssid);
    status = WiFi.begin(ssid, pass);
    delay(5000);
  }

  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());
  IPAddress ip = WiFi.localIP();
  IPAddress gateway = WiFi.gatewayIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  String fv = WiFi.firmwareVersion();
  if (fv != "1.4.8") {Serial.println("Please upgrade the firmware");  }
} // end setup

void loop() {
  
 
  doc["XXXXX"][0] = "XXXXXX";
  doc["XXXX"] = "XXXXX";
  doc["XXXXX"] = "XXXXXX";
  
  Serial.print("Provo a connettermi !...\n\r ");
  if (client.connectSSL(server, 443)) {
	
    Serial.print("Sono connesso !...invio la richiesta POST \n\r ");
    client.println("POST \'https://XXXXXXXXX' ");
   // client.println("Host: https://XXXXXXXX");
    client.println("accept: application/ld+json"); 
    client.println("Content-Type: application/ld+json"); 
    client.println("Connection: close");  
    client.print("Content-Length: 1024");
    client.println(measureJson(doc)); 
    client.println();
    serializeJson(doc, client);
  //  client.print(doc);
  }
  else{Serial.print("Non sono connesso \n\r");}

  if (client.connected()) {
    client.stop();
  }
   Serial.print("Risultato...:   ");
  Serial.println(serializeJson(doc, client));

  delay(3000);
}

Thank you !

Your post was MOVED to its current location, from the ITALIAN section, as it is more suitable.

Could you also take a few moments to Learn How To Use The Forum.

Other general help and troubleshooting advice can be found here.

It will help you get the best out of the forum in the future.

Thank you gpb01 !

I think you will need to remove the "1024".

You may need to send the data to the client before you stop it.

Thank you very much johnwasser and I agree, but the main problem is that I don't reach the server under https !
I've tried even with ArduinoHttpClient library, but the best case is to receive a 400 error or a timeout !
