JSON解析问题

Question

我正在尝试在我的android应用程序中解析Json的链接是https://www.buzzador.com/apps/present_software/webservice/index.php?op=ProductQ&campaign_id=607&userid=10776

当我将其放入Json对象时，它给我带来错误错误是：08-31 14：40：52.281：WARN /
System.err（416）：org.json.JSONException：类型java.lang.String的值无法转换到JSONObject

public static String getmyproductquestiondetails(String userid,
        String campaignid) {// https://www.buzzador.com/apps/present_software/webservice/index.php?op=EducationResult&userid=1&questionid=1,2,3&answergivenbyuser=1,1,0
    String data = null;
    try {

        URL url = new URL(
                "http://dignizant.com/buzz/webservice/index.php?op=getProductQuestion&userid="
                        + userid + "&campaign_id=" + campaignid);
        if (url.getProtocol().toLowerCase().equals("https")) {
            trustAllHosts();
            HttpsURLConnection https = (HttpsURLConnection) url
                    .openConnection();
            https.setHostnameVerifier(DO_NOT_VERIFY);
            http = https;
        } else {
            http = (HttpURLConnection) url.openConnection();
        }
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    Utils utils = new Utils();

    try {
        data = utils.convertStreamToString(http.getInputStream());
        System.out.println("getproduct details response :: " + data);

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();

        data = e.toString();

    }
    return data;
}







try {


        JSONObject jo = new JSONObject(response);

    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }

Answer 1

  char[] utf8 = null;
            StringBuilder properString = new StringBuilder("");

            utf8 = Response.toCharArray();

            for (int i = 0; i < utf8.length; i++) {
                if ((int) utf8[i] < 65000) {
                    properString.append(utf8[i]);
                }
            }
  System.out.println("Response of Login::"
                        + properString.toString());
