Целевой сервер не смог ответить! почему эта ошибка в 000webhost?

Question

Я использую 000webhost как образец db, может ли кто-нибудь помочь мне решить ? Я запускал это приложение как в реальном объекте, так и на эмуляторе.

Я получаю эту ошибку:

07-02 07:17:27.120: W/System.err(2675): org.apache.http.NoHttpResponseException: The target server failed to respond 
07-02 07:17:27.120: W/System.err(2675):  at org.apache.http.impl.conn.DefaultResponseParser.parseHead(DefaultResponseParser.java:85) 

Это мой JSON:

public class JSONParser 
{ 
    static InputStream is = null; 
    static JSONObject jObj = null; 
    static String json = ""; 

    // constructor 
    public JSONParser() { 

    } 

    public JSONObject makeHttpRequest(String url, String method, 
      List<NameValuePair> params) { 

     // Making HTTP request 
     try { 

      // check for request method 
      if(method == "POST"){ 

       DefaultHttpClient httpClient = new DefaultHttpClient(); 
       HttpPost httpPost = new HttpPost(url); 
       httpPost.setEntity(new UrlEncodedFormEntity(params)); 

       HttpResponse httpResponse = httpClient.execute(httpPost); 
       HttpEntity httpEntity = httpResponse.getEntity(); 
       is = httpEntity.getContent(); 

      }else if(method == "GET"){ 
       // request method is GET 
       DefaultHttpClient httpClient = new DefaultHttpClient(); 
       String paramString = URLEncodedUtils.format(params, "utf-8"); 
       url += "?" + paramString; 
       HttpGet httpGet = new HttpGet(url); 

       HttpResponse httpResponse = httpClient.execute(httpGet); 
       HttpEntity httpEntity = httpResponse.getEntity(); 
       is = httpEntity.getContent(); 
      }

     } catch (ClientProtocolException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     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(); 
      json = sb.toString(); 
     } catch (Exception e) { 
      Log.e("Buffer Error", "Error converting result " + e.toString()); 
     } 

     // try parse the string to a JSON object 
     try {

      jObj = new JSONObject(json); 
     } catch (JSONException e) {

     } 

     // return JSON String 
     return jObj;

Теперь ваша регистрация URL не работает.
Сначала сделайте правильный URL-адрес и перейдите к этому URL-адресу в своем веб-браузере.
Затем вы можете проверить рабочий URL-адрес или нет.
Теперь вы можете видеть, что http://mysql14.000webhost.com/sign_up.php недоступен.

Сделайте новую учетную запись хостинга и загрузите все файлы, затем попробуйте.
