Java HttpsURLConnection 响应 JSON 数组

Question

我一直在接收 JSON 对象作为来自 HttpsURLConnection 的响应。我一直在使用它来解析响应。

ObjectMapper map = new ObjectMapper();
JsonNode node = map.readTree(conn.getInputStream());

这对我来说一直很好，但现在我正在接收数组。我该如何解析它们？

这是我收到的响应示例：

"value": [1 ] 0: { "ID": "2135125324" "name": "John" "2ndName": null "lastName": "James" }

如果您正在使用 AsyncTask，请尝试此操作 写下面的代码对你有帮助

private void yourfunction()
{

    class YourClass extends AsyncTask<String, Void, String>
    {


        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected void onPostExecute(String s) {
            super.onPostExecute(s);

            try {
                JSONObject jsonObj = new JSONObject(s);
                user = jsonObj.getJSONArray("value");
                JSONObject c = user.getJSONObject(0);
                String profile = c.getString("ID");
                String name = c.getString("name");



            } catch (JSONException e) {
                e.printStackTrace();
            }


        }

        @Override
        protected String doInBackground(String... params) {
            String s = params[0];
            BufferedReader bufferedReader = null;
            try {
                URL url = new URL("your url string");
                HttpURLConnection con= (HttpURLConnection) url.openConnection();
                bufferedReader=new BufferedReader(new InputStreamReader(con.getInputStream()));
                String result;
                result = bufferedReader.readLine();
                return result;
            }
            catch (Exception e) {
                return null;
            }
        }
    }
    YourClass lu=new YourClass();
    lu.execute();
}
