这是一些使用Java的URL类的经过测试的代码。我建议比在这里处理异常或将异常传递到调用堆栈方面做得更好。
public static void main(String[] args) { URL url; InputStream is = null; BufferedReader br; String line; try { url = new URL("http://stackoverflow.com/"); is = url.openStream(); // throws an IOException br = new BufferedReader(new InputStreamReader(is)); while ((line = br.readLine()) != null) { System.out.println(line); } } catch (MalformedURLException mue) { mue.printStackTrace(); } catch (IOException ioe) { ioe.printStackTrace(); } finally { try { if (is != null) is.close(); } catch (IOException ioe) { // nothing to see here } }}
