当我从本地数据库中获取数据时，我在 Json 对象中获取值并将其转换为字符串，结果可以在本地服务器中看到。
但是..当我在实时数据库上执行相同的代码时，数据无法转换为 Json 对象。
这是我的代码 -
class Createoffer extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
}
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://10.0.2.2/Upshot_Loyalty_Program/android_api_retailer/create_offer.php");
try {
session = new SessionManager(getApplicationContext());
HashMap<String, String> user = session.getUserDetails();
bus_id = user.get(SessionManager.KEY_B_ID);
emp_id = user.get(SessionManager.KEY_E_ID);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
nameValuePairs.add(new BasicNameValuePair("bus_id", bus_id));
nameValuePairs.add(new BasicNameValuePair("offer_name",
offer_name_final));
nameValuePairs.add(new BasicNameValuePair("offer_discount",
offer_discount));
nameValuePairs.add(new BasicNameValuePair("date",
offer_valid_till));
nameValuePairs.add(new BasicNameValuePair("start_time",
offer_starting_time));
nameValuePairs.add(new BasicNameValuePair("end_time",
offer_ending_time));
nameValuePairs.add(new BasicNameValuePair("redeem_times",
offer_times_redeem));
nameValuePairs
.add(new BasicNameValuePair("created_by", emp_id));
nameValuePairs.add(new BasicNameValuePair("offer_created_for",
offer_created_for1));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
response.getStatusLine().getStatusCode();
HttpEntity getResponseEntity = response.getEntity();
responseString = EntityUtils.toString(getResponseEntity);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
return responseString;
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
try {
JSONObject json = new JSONObject(responseString);
JSONArray jArray = json.getJSONArray("customer");
for (int i = 0; i < jArray.length(); i++) {
jsonobj = jArray.getJSONObject(i);
success = jsonobj.getString("success");
System.out.println(success);
}
if (success.equals("1")) {
Intent innv = new Intent(getApplicationContext(),
Offers.class);
Editor editor = sharedpreferences.edit();
editor.clear();
editor.commit();
startActivity(innv);
Toast toast = Toast.makeText(getApplicationContext(),
"Offer sent successful to " + total_eli_cus
+ " customers ", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
} else {
Toast toast = Toast.makeText(getApplicationContext(),
"Offer Not Created", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
这是我在 logcat 中遇到的错误 -

这是我在 JSON 中的结果 -
{
"customer": [
{
"success": "1"
}
]
}
