Интеграция skyscanner api для живых цен

Question

Я пытаюсь получить Location header url для опроса с помощью skyscanner api url http://partners.api.skyscanner.net/apiservices/pricing/v1.0, но я получаю ошибку 500 Volley server. Может ли кто-нибудь сказать мне, что я делаю неправильно. Я получаю ответ заголовка в Postman от Chrome.

public class MainActivity extends AppCompatActivity { 
 
    private static final String URL = "http://partners.api.skyscanner.net/apiservices/pricing/v1.0"; 
 

 

 
    @Override 
 
    protected void onCreate(Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     setContentView(R.layout.activity_main); 
 
    } 
 

 
    public void go(View v){ 
 
     skyscannerpriceapi(); 
 
    } 
 

 
    private void skyscannerpriceapi() { 
 

 
     Map<String, String> params = new HashMap<String, String>(); 
 
     params.put("apiKey", "MY_API_KEY"); 
 
     params.put("country", "US"); 
 
     params.put("currency", "USD"); 
 
     params.put("locale", "en-US"); 
 
     params.put("originplace", "FLL"); 
 
     params.put("destinationplace", "MCO"); 
 
     params.put("outbounddate", "2016-07-20"); 
 
     params.put("inbounddate", "2016-07-27"); 
 
     params.put("locationschema", "iata"); 
 
     params.put("cabinclass", "Economy"); 
 
     params.put("adults", "1"); 
 
     params.put("children", "0"); 
 
     params.put("infants", "0"); 
 
     params.put("groupPricing", "false"); 
 

 
     JsonObjectRequest objectRequest = new JsonObjectRequest(
 
       Request.Method.POST, 
 
       URL, 
 
       new JSONObject(params), 
 

 
       new Response.Listener<JSONObject>() { 
 
        @Override 
 
        public void onResponse(JSONObject response) { 
 
         Toast.makeText(MainActivity.this, response.toString(), Toast.LENGTH_SHORT).show(); 
 
        } 
 
       }, 
 
       new Response.ErrorListener() { 
 
        @Override 
 
        public void onErrorResponse(VolleyError error) { 
 
         Toast.makeText(MainActivity.this, error.toString(), Toast.LENGTH_SHORT).show(); 
 
        } 
 
       }) { 
 

 

 

 
      @Override 
 
      public Map<String, String> getHeaders() throws AuthFailureError { 
 
       HashMap<String, String> headers = new HashMap<String, String>(); 
 
       headers.put("Content-Type", "application/x-www-form-urlencoded"); 
 
       headers.put("Accept", "application/json"); 
 
       return headers; 
 
      } 
 
     }; 
 

 

 
     RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext()); 
 
     requestQueue.add(objectRequest); 
 
    } 
 

 
}

Я использовал HTTPUrlConnecyion и AsyncTask вместо залпа, и я получил желаемый результат.

public class MainActivity extends AppCompatActivity { 
 

 

 
    @Override 
 
    protected void onCreate(Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     setContentView(R.layout.activity_main); 
 
    } 
 

 
    public void go(View v){ 
 
     new MyDownloadTask().execute(); 
 
    } 
 

 
    class MyDownloadTask extends AsyncTask<String, Void, String>{ 
 

 

 
     protected void onPreExecute() { 
 
      //display progress dialog. 
 
      Toast.makeText(MainActivity.this, "Asynctask starts", Toast.LENGTH_SHORT).show(); 
 

 
     } 
 
     protected String doInBackground(String... params) { 
 
      String location = null; 
 

 
      try { 
 

 
       URL obj = new URL("http://partners.api.skyscanner.net/apiservices/pricing/v1.0"); 
 
       HttpURLConnection conn = (HttpURLConnection) obj.openConnection(); 
 
       conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
 
       conn.setRequestProperty("Accept", "application/json"); 
 
       conn.setRequestMethod("POST"); 
 

 
       String urlParameters = "apiKey=MY_API_KEY&country=US&currency=USD&locale=en-US&originplace=SJC&destinationplace=SNA&outbounddate=2016-09-14&inbounddate=2016-09-15&locationschema=iata&cabinclass=Economy&adults=1&children=0&infants=0&groupPricing=false"; 
 
       DataOutputStream dStream = new DataOutputStream(conn.getOutputStream()); 
 
       dStream.writeBytes(urlParameters); 
 
       dStream.flush(); 
 
       dStream.close(); 
 

 

 
       conn.connect(); 
 

 

 
       int status = conn.getResponseCode(); 
 
       System.out.println("Status:" + "\t" + status); 
 

 
       if (status == 201) { 
 

 
        Map<String, List<String>> map = conn.getHeaderFields(); 
 

 
        System.out.println("Printing Response Header...\n"); 
 

 
        for (Map.Entry<String, List<String>> entry : map.entrySet()) { 
 
         System.out.println("Key:" + entry.getKey() + ",Value:" + entry.getValue()); 
 
        } 
 

 
        System.out.println("\n Get Response Header By Key ...\n"); 
 
        location = conn.getHeaderField("Location"); 
 

 
        if (location == null) { 
 
         System.out.println("Key 'Location' is not found!"); 
 
        } else { 
 
         System.out.println("Location - " + location); 
 
        } 
 

 
        System.out.println("\n Looping location..."); 
 

 

 

 
       } 
 

 

 

 

 
      } catch (Exception e) { 
 
       e.printStackTrace(); 
 
      } 
 

 
      return location; 
 
     } 
 

 

 

 
     protected void onPostExecute(String result) { 
 
      Toast.makeText(MainActivity.this, result, Toast.LENGTH_SHORT).show(); 
 
     } 
 
    }
