我似乎无法从Pinterest JSON获取JSON文件

我有一个问题，从pinterest得到JSON，它始终是JSONArray部分的错误。我似乎无法从Pinterest JSON获取JSON文件

代码

JSONArray bodyarray = null; 
JSONParser jParser = new JSONParser(); 
JSONObject json = jParser.getJSONFromUrl(url); 
Log.i("url",""+url); 
Log.i("json",""+json); 
try{  
    bodyarray = json.getJSONArray(TAG_body); <---- this is the error here "NullPointerException" 
    Log.i("JSON", ""+bodyarray); 
}

JSON收到

网址 - http://pinterestapi.co.uk/username/pins

来自Facebook和Twitter的JSON解析时，我没有这个问题，这只是发生在Pinterest的链接。如何获得pinterest链接上的数组？

这是使用

public class JSONParser { 

static InputStream is = null; 
static JSONObject jObj = null; 
static String json = ""; 

// constructor 
public JSONParser() { 

} 

public JSONObject getJSONFromUrl(String url) { 

    // Making HTTP request 
    try { 
     // defaultHttpClient 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpPost httpPost = new HttpPost(url); 

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

    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } 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"); //\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) { 
     Log.e("JSON Parser", "Error parsing data " + e.toString()); 
    } 

    // return JSON String 
    return jObj; 

} 

}

*这是与登录JSON = sb.toStirng）所述的logcat（解析器IM;和str_final *

请学会为Stack Over Flow格式化您的代码。看看我的编辑。此外，始终提供您的logcat堆栈跟踪。 – Snicolas

嗨，请发布您的logcat跟踪以获得快速响应。 – KunalK

这是链接到图像 - > http://s11.postimage.org/sgsksclf7/Screen_Shot_2013_02_08_at_1_22_33_PM.png – questionair

这是一个GET请求。而你使用HttpPost httpPost = new HttpPost（url）;.

将其替换为HttpGet httpGet = new HttpGet（url）;
