Question

 我做一个app想获取pc段数据

public String getContent(String path) {
  try {
   URL url = new URL(path);
   conn = (HttpURLConnection) url.openConnection();
   Log.i("aa", Integer.valueOf(conn.getResponseCode()).toString());
   if (conn.getResponseCode() == 200) {
    is = conn.getInputStream();
    BufferedReader br = new BufferedReader(
      new InputStreamReader(is));
    while ((line = br.readLine()) != null) {
     sb.append(line);
    }
    is.close();
   }
   System.out.println("连接成功!");
  } catch (MalformedURLException e) {
   return sb.toString();
  } catch (IOException e) {
   return sb.toString();
  }
  return sb.toString();
 }
