教你如何得到特定URL网页的源代码

public class WebSpider {public static void main(String[] args) throws Exception {String urlString = "http://lggege.iteye.com/blog/173840";URL url = new URL(urlString);Object contentObj = url.getContent();if (contentObj instanceof InputStream) {new InputStreamReader((InputStream) contentObj);BufferedReader br = new BufferedReader(new InputStreamReader((InputStream) contentObj));StringBuffer sb = new StringBuffer();while (br.ready()) {sb.append(br.readLine());}// 这步还需要处理编码问题.    System.out.println(new String(sb.toString().getBytes(), "UTF-8"));}}}

上面是代码.

在这步:
Object contentObj = url.getContent();
是真正向URL服务器请求得到数据,也就是页面源代码.
