Trying to get a Json from URL, else (if there is no connection) get it from SPIFFS

[ArtalMQS]

Hello to everyone, i'm trying to get a .json file to get some data to my project.
The purpose is to get the file from URL and override it to my .json file stored on SPIFFS.
Else, if there is no connection found i would take the json file directly from SPIFFS.

I tryed to get it from the URL and the test get well, but I can't reach to get it from SPIFFS.
I apologize for my English and any help would be appreciate.

Environment
Here is the environment that I'm using':

• Microconroller: NodeMCU 0.9 (ESP-12 Module)
• Core/runtime: ESP8266 core NodeMCU
• IDE: Arduino IDE 1.8.16

MY CODE

#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <ArduinoJson.h>
#include <FS.h>

const char* ssid = "myssid"; /i use it right
const char* password = "mypsw"; /use my right one too

#include <WiFiClient.h>

WiFiClient wifiClient;

void setup()
{
Serial.begin(115200);
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED)
{
delay(1000);
Serial.println("Connecting...");
}

if (WiFi.status() == WL_CONNECTED)
{
WiFiClient client; // or WiFiClientSecure for HTTPS
HTTPClient http;

// Send request
http.useHTTP10(true);
http.begin(client, "http://acicerone.altervista.org/Questions_Answers.json");
http.GET();


StaticJsonDocument<384> doc;

DeserializationError error = deserializeJson(doc, http.getStream());

if (error) {
  Serial.print(F("deserializeJson() failed: "));
  Serial.println(error.f_str());
  return;
}

JsonArray question = doc["question"];
const char* question_0 = question[0]; // "D3AC5F16"
const char* question_1 = question[1]; // "83707A16"
const char* question_2 = question[2]; // "23995E16"
const char* question_3 = question[3]; // "E3EB5B16"

JsonArray answer = doc["answer"];
const char* answer_0 = answer[0]; // "33757816"
const char* answer_1 = answer[1]; // "E3F36B16"
const char* answer_2 = answer[2]; // "03577B16"
const char* answer_3 = answer[3]; // "F3806916"

Serial.println("....");
Serial.println(question_0);
Serial.println("....");
Serial.println(answer_2);



// Disconnect
http.end();

}
else {
SPIFFS.begin();

File config = SPIFFS.open("config.json", "r");


StaticJsonDocument<384> doc;

DeserializationError error = deserializeJson(doc, config);

if (error) {
  Serial.print(F("deserializeJson() failed: "));
  Serial.println(error.f_str());
  return;
}


JsonArray question = doc["question"];
const char* question_0 = question[0]; // "D3AC5F16"
const char* question_1 = question[1]; // "83707A16"
const char* question_2 = question[2]; // "23995E16"
const char* question_3 = question[3]; // "E3EB5B16"

JsonArray answer = doc["answer"];
const char* answer_0 = answer[0]; // "33757816"
const char* answer_1 = answer[1]; // "E3F36B16"
const char* answer_2 = answer[2]; // "03577B16"
const char* answer_3 = answer[3]; // "F3806916"

Serial.println("__");
Serial.println(question_2);
Serial.println("__");

delay(60000);

}
}
void loop()
{
}
END CODE

the .json file saved to my data SPIFFS is the same at this URL: http://acicerone.altervista.org/Questions_Answers.json

Thanks to everyone

Hi @ArtalMQS,

You should check the status of the HTTP request instead of (only) relying on the status of the WiFi connection.

@ArtalMQS, I'm closing this issue because it is not directly related to ArduinoJson.
I provide live support on codementor if you need.
Thank you for your understanding.

Best regards,
Benoit
