我知道 JSON 解析，但在我当前的项目中，我得到了一些不同类型的 JSON 格式，其中所有对象的名称都是动态的，并且它们可能会发生变化。

所以在 doInBackground() 中，我做的如下:-
@Override
protected String doInBackground(String... params) {
ServiceHandler serviceHandler = new ServiceHandler();
String jsonStr = serviceHandler.makeServiceCall(
Constants.SIDE_DRAWER_SERVICES, ServiceHandler.GET);
try {
JSONObject jobj = new JSONObject(jsonStr);
Log.d("", "" + jsonStr.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return jsonStr;
}
在字符串“jsonStr”中，我得到了完整的响应数据，但是当将其转换为 JSONObject 时，如“JSONObject jobj = new JSONObject(jsonStr);”我缺少这样的数据:-

我不知道我的 JSON 发生了什么。请帮助我并告诉我 JSON 是否无效。
最佳答案
终于解决了，在调试的时候，string显示所有的数据不管多少，但是在JSONObject中所有的数据都可用但是在调试时不显示。当从JSONObject中检索数据时我获取调试器中未显示的所有字段。
