投稿私はJSON形式でサーバーにデータを投稿していますこんにちはボレー

Question

を使用してJSON形式でサーバーへのデータ、 それは

RequestQueue queue = Volley.newRequestQueue(this); 
     JSONObject jobj=new JSONObject(); 
     try { 
      jobj.put("id",”123”); 
      jobj.put("session","new"); 
      JSONArray array = null; 
      array = new JSONArray(); 
      for (int i = 0;i<3;i++){ 
       JSONObject jsonObject = new JSONObject(); 
       jsonObject.put("name","test"); 
       jsonObject.put("content","test"); 
       jsonObject.put("time"," 2016-04-07T11:44:22.407Z "); 
       array.put(jsonObject); 
      } 
      Log.e(" array "," arrr"+array.toString()); 
      jobj.put("data",array); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     Log.e("jsondata",jobj.toString()); 
JsonObjectRequest sr= new JsonObjectRequest(post_url, jobj, new Response.Listener<JSONObject>() { 
      @Override 
      public void onResponse(JSONObject response) { 
          } 

     }, new Response.ErrorListener() { 

      @Override 
      public void onErrorResponse(VolleyError error) { 

      } 
     }){ 
      @OveRequestQueue queue = Volley.newRequestQueue(this); 
     JSONObject jobj=new JSONObject(); 
     try { 
      jobj.put("id",”123”); 
      jobj.put("session","new"); 
      JSONArray array = null; 
      array = new JSONArray(); 
      for (int i = 0;i<3;i++){ 
       JSONObject jsonObject = new JSONObject(); 
       jsonObject.put("name","test"); 
       jsonObject.put("content","test"); 
       jsonObject.put("time"," 2016-04-07T11:44:22.407Z "); 
       array.put(jsonObject); 
      } 
      Log.e(" array "," arrr"+array.toString()); 
      jobj.put("data",array); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     Log.e("jsondata",jobj.toString()); 
JsonObjectRequest sr= new JsonObjectRequest(post_url, jobj, new Response.Listener<JSONObject>() { 
      @Override 
      public void onResponse(JSONObject response) { 
          } 

     }, new Response.ErrorListener() { 

      @Override 
      public void onErrorResponse(VolleyError error) { 

      }rride 
      public Map<String, String> getHeaders() throws AuthFailureError { 
       Map<String,String> params = new HashMap<String, String>(); 
       params.put("Content-Type","application/json"); 
       return params; 
      } 
     }; 
     queue.add(sr);`

response`エラーでボレーサーバーエラーを返しますが、要求キューを処理シングルトンを持っています。

public class VolleySingleton { 

    // Singleton object... 
    private static VolleySingleton instance; 

    final private RequestQueue requestQueue; 
    private static ImageLoader imageLoader; 

    //Constructor... 
    private VolleySingleton(Context context) { 

     requestQueue = Volley.newRequestQueue(context); 

     imageLoader = new ImageLoader(requestQueue, new ImageLoader.ImageCache() { 
      private final LruCache<String, Bitmap> cache = new LruCache<>(100000000); 


      @Override 
      public Bitmap getBitmap(String url) { 
       return cache.get(url); 
      } 

      @Override 
      public void putBitmap(String url, Bitmap bitmap) { 
       cache.put(url, bitmap); 
      } 
     }); 
    } 

    // Singleton method... 
    public static VolleySingleton getInstance(Context context) { 
     if (instance == null) { 
      instance = new VolleySingleton(context); 
     } 
     return instance; 
    } 

    public RequestQueue getRequestQueue(Context context) { 
     if (requestQueue != null) { 
     return requestQueue; 
     } else { 
      getInstance(context); 
      return requestQueue; 
     } 
    } 

    private RequestQueue getRequestQueue() { 
     return requestQueue; 
    } 

    public static ImageLoader getImageLoader(Context context) { 
     if (imageLoader != null) { 
      return imageLoader; 
     } else { 
      getInstance(context); 
      return imageLoader; 
     } 
    } 

    public <T> void addToRequestQueue(Request<T> req) { 
     req.setTag("App"); 
     getRequestQueue().add(req); 
    } 

} 

次に、以下の方法でリクエストを送信できます。

public void postVolley(final Context context, String url, JSONObject jsonObject) { 

     JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST, url, jsonObject, new Response.Listener<JSONObject>() { 

      @Override 
      public void onResponse(JSONObject responseJson) { 
       Log.e("success", "" + responseJson.toString()); 
      } 


     }, new Response.ErrorListener() { 

      @Override 
      public void onErrorResponse(VolleyError error) { 
       Log.e("error", "" + error); 

      } 
     }) { 

      /** 
      * Setting the content type 
      */ 

      @Override 
      public String getBodyContentType() { 
       return "application/json;charset=UTF-8"; 
      } 
     }; 

     VolleySingleton.getInstance(context).addToRequestQueue(jsonObjReq); 

    } 

これは問題なく機能します。
