Question

我正在使用rest ful服务，它会添加额外的自动编号花括号，如下所示：

    {
  "budgets": [
    {
      "id": "1",
      "balance": "0",
      "addedBy": "Jhon",
      "NameBD": "Camping",
      "limitBD": "0",
      "DateBD": "2013-11-16 04:34:03"
    },
    {
      "id": "2",
      "balance": "0",
      "addedBy": "Aziz",
      "NameBD": "My Home",
      "limitBD": "0",
      "DateBD": "2013-11-16 10:33:11"
    },
    {
      "id": "3",
      "balance": "0",
      "addedBy": "Ryd",
      "NameBD": "My Department",


       "limitBD": "0",
          "DateBD": "2013-10-24 17:40:43"
        }
    ]
  }

当我尝试解析它们时，它在“预算”中没有显示任何价值所以我试图在JSON Viewer中查看它们：

这是我在休息控制器中的PHP函数：

public function allbudget_get()
    {
        $data = $this->db->get('budget');
        $this->response( array('budgets'=>$data->result()) , 200);
    }

有没有办法删除它们？

更新：应用代码为：

private class DownloadJSON extends AsyncTask<Void, Void, Void> {

        @Override
        protected Void doInBackground(Void... params) {
            // Locate the Class 
            bd = new ArrayList<AllBudgets>();
            // Create an array to populate the spinner 
            bdlist = new ArrayList<String>();
            // JSON file URL address
            jsonobject = JSONfunctions
                    .getJSONfromURL("http://localhost/SharedBudget/index.php/Budget/allbudget");

            try {
                // Locate the NodeList name
                jsonarray = jsonobject.getJSONArray("budgets");
                for (int i = 0; i < jsonarray.length(); i++) {
                    jsonobject = jsonarray.getJSONObject(i);

                    AllBudgets bdget = new AllBudgets();

                    bdget.setId(jsonobject.optString("id"));
                    bdget.setAddedBy(jsonobject.optString("addedBy"));
                    bdget.setNameBD(jsonobject.optString("NameBD"));
                    bdget.setDateBD(jsonobject.optString("DateBD"));
                    bdget.add(bdget);

                    // Populate spinner with budget names
                    bdlist.add(jsonobject.optString("NameBD"));

                }
            } catch (Exception e) {
                Log.e("Error", e.getMessage());
                e.printStackTrace();
            }
            return null;
        }

以下是用于解析的JSON代码

公共类JSONfunctions {

    public static JSONObject getJSONfromURL(String url) {
        InputStream is = null;
        String result = "";
        JSONObject jArray = null;

        // Download JSON data from URL
        try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(url);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

        } catch (Exception e) {
            Log.e("log_tag", "Error in http connection " + e.toString());
        }

        // Convert response to string
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result = sb.toString();
        } catch (Exception e) {
            Log.e("log_tag", "Error converting result " + e.toString());
        }

        try {

            jArray = new JSONObject(result);
        } catch (JSONException e) {
            Log.e("log_tag", "Error parsing data " + e.toString());
        }

        return jArray;
    }
}

更新LOGCAT 我也有安装人员和吸气但我知道它们不是logcat显示的问题：

Answer 1

我找到了答案，我使用了httpPost，而函数使用了GET，所以我只是替换了它：

HttpGet httpget = new HttpGet(url);
