我需要的响应转换成字符串..如何接收JSON响应

 HttpClient httpclient = new DefaultHttpClient(); 
     Log.d("HTTP","Exe"); 
     String url=Sign(token); 
     Log.d("HTTP","Exe"); 

     HttpPost httpPost; 
     httpPost = new HttpPost(url);

响应（JSON）应该是我如何收到类似

{ 
    "url": "http://db.tt/APqhX1", 
    "expires": "Tue, 01 Jan 2030 00:00:00 +0000" 
}

这是将任何json作为http响应的方式。我希望这将是有用的。

HttpResponse response = httpclient.execute(httppost); 
HttpEntity entity = response.getEntity(); 
InputStream is = entity.getContent(); 

try { 
    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"), 256); 
StringBuilder sb = new StringBuilder(); 
String line = null; 
while ((line = reader.readLine()) != null) sb.append(line); 
    result = sb.toString(); 
is.close(); 
} catch (Exception e) {} 

JSONArray jArray = new JSONArray(result); 
for(int i = 0; i < jArray.length(); i++) { 
JSONObject json_data = jArray.getJSONObject(i); 
String url= json_data.getString("url"); 
    String expires= json_data.getString("expires"); 
}

有很多例子，如果你google和反正尝试：

 response = client.execute(httpPost); 
    HttpEntity httpEntity = response.getEntity(); 
    InputStream is = httpEntity.getContent();

..将Inputstream转换为字符串
