So rufen Sie zwei Json-Antworten Json Object und Array ab

HINWEIS :Wie in der vorherigen Frage erwähnt, muss die angegebene JSON-Zeichenfolge das richtige Format haben, d. h. entweder einen Schlüssel für jedes Objekt (Login, Konten) oder sie in einem einzigen Array (Eingabe) haben. Ich gebe Lösung für beide Optionen.

Anfänger, ich stelle Ihnen 2 separate Methoden zur Verfügung, damit Sie eingehende JSON-Zeichenfolgen verarbeiten können, je nachdem, wie Sie sie entweder als 2 Objekte in einer einzelnen JSON-Zeichenfolge oder als 2 Objekte in einem JSON-Array konstruieren.

Sie können Ihre Lösung auswählen :)

Probieren Sie den Code aus, lassen Sie es mich wissen, wenn Sie weitere Hilfe benötigen, und akzeptieren Sie die Antwort.

OPTION1 :2 Objekte in einer einzelnen JSON-Zeichenfolge

{
   "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 Objekte in einem einzelnen JSON-Array-String

{
   "input":[
      {
         "error":false,
         "user":{
            "br_code":12,
            "mem_id":13,
            "username":"novalyn",
            "email":"[email protected]",
            "created_at":"2016-07-22 09:05:21"
         }
      },
      {
         "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"
            }
         ]
      }
   ]
}

Ich habe keinen Zugriff auf alle internen PHP-Dateien, die ich zum Ausführen Ihres PHP-Codes verwenden kann, daher habe ich die meisten Funktionsaufrufe durch hartcodierte Werte ersetzt, wie sie in der Nutzlast der Beispielantwort geteilt werden. Hier ist der Code zum Generieren von JSON-Objekten im OPTION1-Format.

Kurz gesagt, Sie müssen ["login"] und ["accounts"] vor allen Unterattributen in $response hinzufügen, damit sie im richtigen JSON-Objekt gruppiert werden und Sie zwei JSON-Objekte haben, die oben analysiert werden können freigegebener Android-Code.

<?php
// json response array
$br_response = array("error" => FALSE);
$sl_response["error"] = FALSE;
$sl_response["sl_summ"] = array();

$arclass = "13";
$loanclass = "12";
$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";
        $response["login"]["user"]["email"] = "[email protected]";
        $response["login"]["user"]["created_at"] = "2016-07-22 09:05:21";
                 for($i = 0; $i < 2; $i++){
                        $item = array();
                        $item["sl_desc"] = "PA : Savings Account";
                        $item["tr_date"] = "2015-08-17";
                        $item["actual_balance"] = "483.67";
                        $item["available_balance"] = "483.67";
                        $sl_response["sl_summ"][] = $item;
                    }
                    $response["accounts"] = $sl_response;
                    json_encode($response);
                    echo json_encode($response, true);
