REMARQUE :comme mentionné dans la question précédente, la chaîne JSON donnée doit être au format correct, c'est-à-dire avoir une clé pour chaque objet (connexion, comptes) ou les avoir dans un seul tableau (entrée). Je donne une solution pour les deux options.
Novice, je vous propose 2 méthodes distinctes afin que vous puissiez gérer la chaîne JSON entrante en fonction de la façon dont vous la construisez, soit 2 objets dans une seule chaîne JSON, soit 2 objets dans un tableau JSON.
Vous pouvez choisir votre solution :)
Essayez le code, faites-moi savoir si vous avez besoin de plus d'aide et acceptez la réponse.
OPTION1 :2 objets dans une seule chaîne JSON
{
"login":{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",
"email":"[email protected]",
"created_at":"2016-07-22 09:05:21"
}
},
"accounts":{
"error":false,
"sl_summ":[
{
"sl_desc":"PA : Savings Account",
"tr_date":"2015-08-17",
"actual_balance":"483.67",
"available_balance":"483.67"
},
{
"sl_desc":"PA : Savings - Cash Bond",
"tr_date":"2015-08-28",
"actual_balance":"10129.43",
"available_balance":"10129.43"
}
]
}
}
OPTION2 :2 objets dans une seule chaîne de tableau JSON
{
"input":[
{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",

Je n'ai pas accès à tous les fichiers PHP internes que je peux utiliser pour exécuter votre code PHP, j'ai donc remplacé la plupart des appels de fonction par des valeurs codées en dur telles que partagées dans l'exemple de charge utile de réponse. Voici le code pour générer des objets JSON au format OPTION1.
En bref, vous devez ajouter ["login"] et ["accounts"] devant tous les sous-attributs dans $response afin qu'ils soient regroupés dans le bon objet JSON et vous aurez deux objets JSON qui peuvent être analysés ci-dessus code partagé Android.
<?php

$br_response = array("error" => FALSE);
$sl_response["error"] = FALSE;
$sl_response["sl_summ"] = array();
$arclass = "13";

$accintreceivable = "21";
// user is found
$response["login"]["error"] = FALSE;
$response["login"]["user"]["br_code"] = 12;
$response["login"]["user"]["mem_id"] = 13;
$response["login"]["user"]["username"] = "novalyn";
