任何人都可以帮助我，这段代码不提供任何输出

Answer 1

尝试h2.product-description__title

您可以在此处看到它：http://try.jsoup.org/~Mkx5qLNvIT2cxUHdNLl9vdTUnYM

Answer 2

看起来服务器需要一个有效的UserAgent字符串。将其添加到代码中：

String url = "http://www.lazada.com.my/asus-zenfone-c-zc451cg-16gb-white-2801812.html";
Document doc = Jsoup.connect(url)
       .userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.1")
       .get();
Elements description = doc.select("h2.product-description__title");
System.out.println("Description :"+description);
System.out.println("Price is " + doc.select("#pdtprice").text());

修改
我加了价格。

使用JSoup提取标题
