Httppost不工作​​ - 在Android中获取html响应而不是JSON

Question

我正在尝试使用httppost连接到服务器，但我不能因为某些错误。 这是我的android代码：

public class SendPostRequest extends AsyncTask<String, Void, String> {

        protected void onPreExecute(){}

        protected String doInBackground(String... arg0) {

            try{

                URL url = new URL("http://abhirathod.byethost4.com/post.php");

                JSONObject postDataParams = new JSONObject();
                postDataParams.put("name", "abc");
                postDataParams.put("email", "abc@gmail.com");
                Log.e("params", postDataParams.toString());

                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setReadTimeout(15000 /* milliseconds */);
                conn.setConnectTimeout(15000 /* milliseconds */);
                conn.setRequestMethod("POST");
                conn.setDoInput(true);
                conn.setDoOutput(true);

                OutputStream os = conn.getOutputStream();

                BufferedWriter writer = new BufferedWriter(
                        new OutputStreamWriter(os, "UTF-8"));
                writer.write(getPostDataString(postDataParams));



                int responseCode=conn.getResponseCode();

                if (responseCode == HttpsURLConnection.HTTP_OK) {

                    BufferedReader in=new BufferedReader(
                            new InputStreamReader(
                                    conn.getInputStream()));
                    StringBuffer sb = new StringBuffer("");
                    String line="";

                    while((line = in.readLine()) != null) {

                        sb.append(line);
                        break;
                    }

                    in.close();
                    return sb.toString();

                }
                else {
                    return new String("false : "+responseCode);
                }

            }
            catch(Exception e){
                return new String("Exception: " + e.getMessage());
            }



        }

        @Override
        protected void onPostExecute(String result) {

            Toast.makeText(getApplicationContext(), result,
                    Toast.LENGTH_LONG).show();

        }
    }

    public String getPostDataString(JSONObject params) throws Exception {

        StringBuilder result = new StringBuilder();
        boolean first = true;

        Iterator<String> itr = params.keys();

        while(itr.hasNext()){

            String key= itr.next();
            Object value = params.get(key);

            if (first)
                first = false;
            else
                result.append("&");

            result.append(URLEncoder.encode(key, "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(value.toString(), "UTF-8"));

        }
        return result.toString();
    }

我一次调用execute方法。我得到了这个输出：

final RequestQueue requestQueue = Volley.newRequestQueue（getApplicationContext（））;         final StringRequest stringRequest = new StringRequest（Request.Method.POST，Appconfig.Url，new Response.Listener（）{             @覆盖             public void onResponse（String response）{

                jsonObject = new JSONObject(response);

                for(int i=0; i<jsonArray.length(); i++) {
                    JSONObject jsonObject1 = jsonArray.getJSONObject(i);

                    String SONG_ID = jsonObject1.getString("SONG_ID");
