java 根据URL获取网页源码
import java.io.BufferedReader;import java.io.InputStreamReader;import java.net.URL;public class webPageResource {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubwebPageResource t6=new webPageResource();String htmls= t6.getPageSource("http://www.no5.com.cn/browse/specialprice_p2.html","GBK");System.out.println(htmls);}public String getPageSource(String pageUrl,String encoding) { StringBuffer sb = new StringBuffer(); try { //构建一URL对象 URL url = new URL(pageUrl); //使用openStream得到一输入流并由此构造一个BufferedReader对象 BufferedReader in = new BufferedReader(new InputStreamReader(url .openStream(), encoding)); String line; //读取www资源 while ((line = in.readLine()) != null) { sb.append(line); sb.append("\n"); } in.close(); } catch (Exception ex) { System.err.println(ex); } return sb.toString(); } } 1 楼 leavesforeye 2012-09-21 怎么会这样。 2 楼 lsjinpeng 2012-09-21 先通过3w字符串获取一个URL对象，然后open URL流，交给InputStreamReader字符流写入处理，并指定编码格式，再封装给BufferReader字符串流读取对象处理，while循环，读取line，append到sb
