Topic: what format for the server URL? (Read 858 times) previous topic - next topic


Hi everyone, sorry in advance for my low level of English :)

I test the example "WifiWebClient" with the arduino MKR 1010.
Everything works when I connect to 'https://serveur.com' but not with an address 'https://serveur.com/folder' or 'https://serveur.com/folder/page.php'
So my question: is it possible to retrieve the html code from an address 'https://serveur.com/folder/page.php'?
Thank you so much!

Code: [Select]
#include <SPI.h>
#include <WiFiNINA.h>

#include "arduino_secrets.h"
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID;        // your network SSID (name)
char pass[] = SECRET_PASS;    // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0;            // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS;
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:

char server[] = "www.server.com/folder/page.php";    // is this URL format correct?

// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
WiFiClient client;

void setup() {
  //Initialize serial and wait for port to open:
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only

  // check for the WiFi module:
  if (WiFi.status() == WL_NO_MODULE) {
    Serial.println("Communication with WiFi module failed!");
    // don't continue
    while (true);

  String fv = WiFi.firmwareVersion();
  if (fv < "1.0.0") {
    Serial.println("Please upgrade the firmware");

  // attempt to connect to Wifi network:
  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
    status = WiFi.begin(ssid, pass);

    // wait 10 seconds for connection:
  Serial.println("Connected to wifi");

  Serial.println("\nStarting connection to server...");
  // if you get a connection, report back via serial:
  if (client.connect(server, 80)) {
    Serial.println("connected to server");
    // Make a HTTP request:
    client.println("GET /search?q=arduino HTTP/1.1");

    client.println("Host: www.server.com/folder/page.php"); // is this URL format correct?

    client.println("Connection: close");

void loop() {
  // if there are incoming bytes available
  // from the server, read them and print them:
  while (client.available()) {
    char c = client.read();

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
    Serial.println("disconnecting from server.");

    // do nothing forevermore:
    while (true);

void printWifiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");

  // print your board's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");

  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI):");
  Serial.println(" dBm");


The example URL "https://serveur.com/folder/page.php" break down like this.

"https" specifies TLS/SSL which the sketch does not handle. But the server may work without TLS/SSL so ignore it for now. The WiFiNINA library includes a TLS/SSL example, if needed.

The server name is "serveur.com". The path is "/folder/page.php". The affected lines of code follow.

Code: [Select]
char server[] = "serveur.com";
client.println("Host: serveur.com");
client.println("GET /folder/page.php HTTP/1.1");


oh a big thank you to you, it works very well :)
