如何通过网络获取Html代码？下面小编带来一篇关于网络获取Html代码原理的文章，仅供参考。
package cn.captain.html; import java.io.ByteArrayOutputStream; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; public class htmlRequest { /** * @param args * @throws MalformedURLException */ public static void main(String[] args) throws Exception { URL url = new URL("http://www.baidu.com/"); HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setRequestMethod("GET"); conn.setConnectTimeout(5 * 1000); InputStream inStream = conn.getInputStream();//通过输入流获取html数据 byte[] data = readInputStream(inStream);//得到html的二进制数据 String html = new String(data); System.out.println(html); } public static byte[] readInputStream(InputStream instream) throws Exception { ByteArrayOutputStream outStream = new ByteArrayOutputStream(); byte[] buffer = new byte[1204]; int len = 0; while ((len = instream.read(buffer)) != -1) { outStream.write(buffer,0,len); } instream.close(); return outStream.toByteArray(); } }通过互联网获取Html代码就是这么来的。网络获取Html代码的详细原理。更多信息请关注AdminJS的其他相关文章！
