獲取HTML頁面源代碼而不是JSON響應

我有一個私有的Web服務，我需要通過身份驗證和JSONObject請求。身份驗證進行得很完美，響應也可以，但作爲響應，我正在獲取特定Web服務實現頁面的HTML頁面源代碼。獲取HTML頁面源代碼而不是JSON響應

他們的任何問題與我發送的JSONObject請求。

請參考下面的代碼：

公衆的JSONObject getJSONFromUrl（字符串URL）{ 嘗試 { DefaultHttpClient的HttpClient =新DefaultHttpClient（）;

 HttpPost httppost=new HttpPost(url); 
     httppost.setHeader("Authorization", "Basic "+Base64.encodeToString("abc:xyz".getBytes(), Base64.NO_WRAP)); 

     //Posting request on htt 
      httppost.setHeader("Content-Type", "application/json");   
      httppost.setHeader("Accept","application/json"); 
      JSONObject jsonPara = new JSONObject();  
      jsonPara.put("password", "abc"); 
      jsonPara.put("username", "abc"); 




      JSONObject jsonobj=new JSONObject(); 

      jsonobj.put("request", "syncdata/get_country"); 
      jsonobj.put("para",jsonPara); 

      Log.i("jason Object", jsonobj.toString()); 

      StringEntity se2 = new StringEntity(jsonobj.toString()); 

      se2.setContentEncoding("UTF-8"); 
      se2.setContentType("application/json"); 

      httppost.setEntity(se2); 
     HttpResponse httpResponse=httpClient.execute(httppost); 
     HttpEntity httpEntity=httpResponse.getEntity(); 
     is=httpEntity.getContent(); 
    } 
    catch(UnsupportedEncodingException ae) 
    { 
    ae.printStackTrace();   
    } 
    catch(ClientProtocolException ae) 
    { 
     ae.printStackTrace(); 
    } 
    catch(IOException ae) 
    { 
     ae.printStackTrace(); 
    } 
    catch(JSONException 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 ae) 
    { 
     ae.printStackTrace(); 
    } 

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

    return jObj; 
}

而且我怎樣才能確認，我得到的響應是JSON或其他某種格式（其他然後調試）和我會得到我真正應該得到正確的響應。

請參閱此代碼。

我希望它會幫助你...

MainActivity.java

HttpEntity entity = response.getEntity(); 
is = entity.getContent(); 
Log.e("Pass 1", "connection success ");
