通过rss取csdn帖子URL列表(java版)

本文提供方法可以通过rss简单取得csdn帖子URL.
方法实现基本原理 :通过HttpURLConnection发送请求并取得返回字符串.用正则表达式匹配帖子URL.

public void SendURLPost() throws IOException {//rss的URLString urlStr = "http://forum.csdn.net/Rss/J2SE/UnClosedList";URL url = new URL(urlStr);HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); // 获取连接httpURLConnection.setRequestMethod("POST"); // 设置请求方法为POST, 也可以为GEThttpURLConnection.setDoOutput(true);// StringBuffer param = new StringBuffer("ArticleId="); //请求URL的查询参数// param.append(articleId);OutputStream os = httpURLConnection.getOutputStream();// os.write(param.toString().getBytes());os.flush();os.close();InputStream is = httpURLConnection.getInputStream();BufferedReader br = new BufferedReader(new InputStreamReader(is,"utf-8"));StringBuilder sb = new StringBuilder();while (br.read() != -1) { sb.append(br.readLine());}String content = new String(sb);br.close();is.close();String regEx = "(.*?)";//Pattern.CASE_INSENSITIVE启用不区分大小写模式Pattern p = Pattern.compile(regEx,Pattern.CASE_INSENSITIVE);Matcher m = p.matcher(content);while(m.find()){System.out.println(m.group(1));}}
