获取一个URL的返回数据

即给定一个URL，使用getReturnData（）进行解析

public String getReturnData(String urlString) throws UnsupportedEncodingException {
        String res = "";
        try {
            URL url = new URL(urlString);
            java.net.HttpURLConnection conn = (java.net.HttpURLConnection)url.openConnection();
            conn.setDoOutput(true);
            conn.setRequestMethod("GET");
            java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(conn.getInputStream(),"UTF-8"));
            String line;
            while ((line = in.readLine()) != null) {
                res += line;
            }
            in.close();

        } catch (Exception e) {
            log.info("error in wapaction,and e is " + e.getMessage());
        }

        return res;
    }
