public static byte[] readStream(InputStream inputStream) throws Exception {byte[] buffer = new byte[1024];int len = -1;ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();while ((len = inputStream.read(buffer)) != -1) {byteArrayOutputStream.write(buffer, 0, len);}inputStream.close();byteArrayOutputStream.close();return byteArrayOutputStream.toByteArray();}public static String testGetHtml(String urlpath) throws Exception {URL url = new URL(urlpath);HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.setConnectTimeout(6 * 1000);conn.setRequestMethod("GET");if (conn.getResponseCode() == 200) {InputStream inputStream = conn.getInputStream();byte[] data = readStream(inputStream);String html = new String(data);return html;}return null;} 主要就是俩函数，一个负责连接网页(testGetHtml())，一个用于读取源码(readStream())：
