使用HttpUrlConnection连接网络的例程

new Thread(new Runnable() {
 
    @Override
 
    public void run() {
 
     String urlString = "
 ​​​http://www​​​....";
 
     HttpURLConnection conn = null;
 
     try {
 
      URL url = new URL(urlString);
 
      conn = (HttpURLConnection) url.openConnection();
 
      conn.setRequestMethod("GET");
 
      conn.setConnectTimeout(8000);
 
      conn.setReadTimeout(8000);
 
      InputStream in = conn.getInputStream();
 
      // 下面对获得的输入流进行读取
 
      BufferedReader reader = new BufferedReader(
 
        new InputStreamReader(in));
 
      StringBuilder sb = new StringBuilder();
 
      String line;
 
      while ((line = reader.readLine()) != null) {
 
       sb.append(line);
 
      }
 
      Message msg = new Message();
 
      msg.what = 1;
 
      msg.obj = sb.toString();
 
      handler.sendMessage(msg);
 
     } catch (Exception e) {
 
      e.printStackTrace();
 
     } finally {
 
      if (conn != null)
 
       conn.disconnect();
 
     }
 
    }// run方法结束
 
   });// 线程结束
