org.json.JSONException：值 {“storeid0”:[“1535”],“storeid1”:[“1862”]} 類型為 org.json.JSONObject 的 idddsss 無法轉換為 JSONArray

Question

我從我的 api 收到此回復

{"idddsss":{"storeid0":["1535"],"storeid1":["1862"]}}

這是我用來從服務器獲取響應並將所有 storeids 保存在數組中的代碼：

public ArrayList<String> tripItems = new ArrayList<>();
    private void getAllStoreIds(String user_id){

        String url = Baseurl.getCartDetails+"?user_id="+user_id;

        StringRequest postStringRequest = new StringRequest(Request.Method.POST, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d(TAG, "ResponseCheck :" + response);
                        tripItems.clear();
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            JSONArray json = jsonObject.getJSONArray("idddsss");
                            if(json.length ()> 0){
                                for(int countItem = 0;countItem<json.length();countItem++){
                                    JSONObject o = json.getJSONObject(countItem);
                                }

                                if (!tripItems.equals(null)) {
                                    for (int i = 0; i < tripItems.size(); i++) {
                                        Toast.makeText(myContext, tripItems.get(i), Toast.LENGTH_SHORT).show();
                                    }
                                }

                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                            Toast.makeText(myContext, e.getMessage()+ "Error", Toast.LENGTH_SHORT).show();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(myContext, error.getCause().toString(), Toast.LENGTH_SHORT).show();
            }
        });

但是每當我運行代碼時，我都會遇到以下錯誤，我不知道為什么，我首先將我的代碼解析為 JSONObject，然后解析為 JSONArray，並且在循環中我再次將其解析為 JSONObject。

Answer 1

idddsss 是 object，所以使用getJSONObject代替getJSONArray

JSONObject objIdddsss = jsonObject.getJSONObject("idddsss");
JSONArray jsonArray = objIdddsss.getJSONArray("storeid0");
Log.v("ANS", objIdddsss.toString());
Log.v("ANS", jsonArray.toString());
