Question

以下代码在netbeans中工作正常，但在eclipse ADT中，doc.select("div#tickertape_eng a").size()返回0。

try {
            Document doc = Jsoup.connect("http://bdnews24.com").get();
            if (doc != null) {
                Elements links = doc.select("div#tickertape_eng a");
                for (Element link : links) {
                    headlines.add(link.text());
                    headlinks.add(link.absUrl("href"));
                }

            } else {
                Toast.makeText(getActivity(), "Doc not found",
                        Toast.LENGTH_LONG).show();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

在netbeans中，我可以打印link.text（）和link.absUrl（＆＃34; href＆＃34;），但不能在eclipse中打印。 Eclipse在logcat中打印doc.title（），但为什么doc.select（＆＃34; div＃tickertape_eng a＆＃34;）不起作用？如何使它工作？

Answer 1

试试这个：

Document doc = Jsoup.connect("http://bdnews24.com")
  .userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0")
  .get();

用户代理是服务器猜测您正在使用哪个浏览器的原因。如果它检测到移动浏览器，则可以将您重定向到移动页面。因此，强制使用桌面浏览器用户代理是确保您获得位于bdnews24.com的标准页面的方法。

Answer 2

试试这个，

Document doc = Jsoup.connect("http://bdnews24.com").get();
Elements div = doc.select("div#tickertape_eng");

   Elements get = div.select("a[href]");

     for (Element elem : get) {

         System.out.println("Link : " +elem.attr("href"));
         System.out.println("Text  : " +elem.text());        
    }
}

为什么Jsoup选择器div＃id在netbeans中工作但在eclipse ADT中不工作？
