GET请求JSONObject android

Question

我做了一个简单的GET请求,如果我的登录名和密码是正确的,则返回1或0.我在另一个线程上建立连接.

像这样 :

public void getConnection(){

    String url = null;

    url = NOM_HOTE + PATH_METHODE + "identifiant="+ identifiant.getText().toString() + "&password="+ password.getText().toString();

     HttpClient httpClient = new DefaultHttpClient();

     try{
         HttpGet httpGet = new HttpGet(url);
         HttpResponse httpResponse = httpClient.execute(httpGet);
         HttpEntity httpEntity = httpResponse.getEntity();

         if(httpEntity != null){


             InputStream inputStream = httpEntity.getContent();

             //Lecture du retour au format JSON
             BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
             StringBuilder stringBuilder = new StringBuilder();

             String ligneLue = bufferedReader.readLine();
             while(ligneLue != null){
                 stringBuilder.append(ligneLue + " \n");
                 ligneLue = bufferedReader.readLine();
             }
             bufferedReader.close();

             JSONObject jsonObject = new JSONObject(stringBuilder.toString());

             Log.i("Chaine JSON", stringBuilder.toString());   


             JSONObject jsonResultSet = jsonObject.getJSONObject("nb"); <--it's here where the error occured

//               int nombreDeResultatsTotal = jsonResultSet.getInt("nb");
//               Log.i(LOG_TAG, "Resultats retourne" + nombreDeResultatsTotal);    

         }// <-- end IF          
     }catch (IOException e){
         Log.e(LOG_TAG+ "1", e.getMessage());
     }catch (JSONException e){
         Log.e(LOG_TAG+ "2", e.getMessage());

     }
}

我有这样的JSON返回:{"nb":"1"}或者{"nb":"0"} 所以我的JSON是正确的.但是catch(JSONException当我提交表单时,我有这个错误:

11-07 17:01:57.833:E/ClientJSON2(32530):类型为java.lang.String的nb处的值1无法转换为JSONObject

我不明白为什么,虽然我的语法,连接是正确的,并在带有标签"Chaine JSON"的日志,我{"nb:"1"}在响应..

Answer 1

nb是a String,而不是a JSONObject.更改

JSONObject jsonResultSet = jsonObject.getJSONObject("nb");

在

String result = jsonObject.getString("nb");
