我會盡量簡要介紹一下，請問是否有什麼不清楚的地方。我從vk.com（一個大型社交網絡，以防有人不知道）獲取用戶的音頻列表。響應的樣子：android-解析服務器的JSON響應時出錯
{"response":[{
"aid":"60830458","owner_id":"6492","artist":"Noname","title":"Bosco",
"duration":"195","url":"http:\/\/cs40.vkontakte.ru\/u06492\/audio\/2ce49d2b88.mp3"},
{"aid":"59317035","owner_id":"6492","artist":"Mestre Barrao","title":"Sinhazinha",
"duration":"234","url":"http:\/\/cs510.vkontakte.ru\/u2082836\/audio\/
d100f76cb84e.mp3"}]}
通常是更長的時間，因爲用戶可以有幾百甚至上千上他的個人資料的軌道。藝術家和標題也可以包含西裏爾字母，這就是爲什麼我在解析器中使用UTF-8的原因。我不是很熟悉JSON，我試圖用下面解析響應：（索引0非法字符方案）
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public JSONParser() {
}
public static JSONObject getJSONFromUrl(String url) {
try {
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, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
return jObj;
}
}
但應用程序崩潰與一個IllegalArgumentException異常：

任何想法我做錯了什麼，以及什麼是解析給定格式的響應的正確方法？有很多應用程序使用相同的API，所以JSON是正確的。不知道這裏有什麼問題
你的json無效。 – hardartcore 2013-02-27 09:15:45
謝謝，但就像我提到的有很多應用程序使用相同的，它的工作原理。 vk支持團隊也表示JSON是正確的，我必須在我身邊尋找問題 – Droidman 2013-02-27 09:17:19
正如我可以看到問題出現在url中，在將它們更改爲其他字符串之後，它將解析json。 – hardartcore 2013-02-27 09:18:48
