jsoup 抓取 reddit

jsoup.java

	public static List<Title> parseHtml(String name) {
		List<Title> lists = new ArrayList<Title>();
		//URL
		String getUrl = "http://www.reddit.com/"; 
		if(name!=null) {
			getUrl=getUrl+"/search?q="+name;
		}
		//标记选取规则
		String g1 = ".title >a";
		//属性选取规则
		String g2 = "abs:href"; 
		try {
	//try { --- 代码的格式化也是很重要的哦

			Document doc = Jsoup.connect(getUrl).timeout(60000).get();

			Elements links = doc.select(g1);

			//int i=0;
			int i = 0; // -------- 代码规范
			for (Element link : links) {
			  // 变量名要尽量有意义
				Title redditLink = new Title();
				String bookTitle = link.text(); 
				String bookURL = link.attr(g2); 
				redditLink.setTitle(bookTitle);
				redditLink.setHref(bookURL);
				lists.add(redditLink);
				//System.out.println("链接 "+i+++": "+bookURL + " 标题" + bookTitle);
				// 这个 +i+++ 让我多理解了一下哈
				System.out.println("链接 " + i++ + ": " + bookURL + " 标题" + bookTitle);
				// 我们可以通过 logger 代替 systemout 来查看系统的运行状况
			}

		} catch (IOException e) {
			System.out.println("抓取异常");
			e.printStackTrace();
		}
		return lists;
