Json data recovery with ESP8266

[bens111]

Hello,

I'm really desasperate and I hope to find someone to help me.
I have a project and I do recovery a data from an API with an ESP8266. from this API : https://api.eliapp.io/groups/bf203bd2-55d9-4975-ad73-eab097dc9528/monthlyStatistics/aggregate?m=["2023-05","2023-06"]

I succeed to connect my ESP to the page , but the answer is empty.

Here you'll can find my code :

#include <ESP8266WiFiMulti.h>
#include <ESP8266HTTPClient.h>
#include <WiFiClientSecure.h>
#include <ArduinoJson.h>

ESP8266WiFiMulti WiFiMulti;

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);

  WiFi.mode(WIFI_STA);
  WiFiMulti.addAP("", ""); // Vos informations WiFi

  // Attendez que la connexion WiFi soit établie
  while (WiFiMulti.run() != WL_CONNECTED) {
    delay(100);
  }
}

void loop() {
  if (WiFiMulti.run() == WL_CONNECTED) {
    WiFiClientSecure client;
    client.setInsecure();

    HTTPClient http;
    String url = "https://api.eliapp.io/groups/bf203bd2-55d9-4975-ad73-eab097dc9528/monthlyStatistics/aggregate?m=[%222023-05%22,%222023-06%22]";
    http.begin(client, url);
    http.addHeader("Accept", "application/json");
    http.addHeader("User-Agent", "Mozilla/5.0");

    int httpCode = http.GET();

    if (httpCode == HTTP_CODE_OK) {
      String payload = http.getString();
      Serial.println("Réponse reçue :");
      Serial.println(payload);

      // Code pour analyser le JSON
    } else {
      Serial.print("Erreur lors de la requête HTTP: ");
      Serial.println(http.errorToString(httpCode));
    }

    http.end();
  } else {
    Serial.println("WiFi non connecté");
  }

  delay(10000);
}

Thanks for your help
