获取国家气象局数据

获取国家气象局数据，urlPath：http://m.weather.com.cn/data/101010100.html

public static String GetWeatherData(String urlPath) throws Exception{URL url = new URL(urlPath);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.connect();InputStream inputStream = connection.getInputStream();Reader reader = new InputStreamReader(inputStream, "UTF-8");BufferedReader bufferedReader = new BufferedReader(reader);String str = null;StringBuffer sb = new StringBuffer();while ((str = bufferedReader.readLine()) != null) {sb.append(str);}reader.close();connection.disconnect();return sb.toString();}

本来想在JS中实现，可是涉及到跨域问题，整了半天没弄出来。希望有知道的能告诉我
