使用JAVA将window.open（Hyperlink）Javascript代码转换为纯绝对URL

Question

我在使用JAVA Jsoup Library的网站上工作以提取一些超链接

Document doc = Jsoup.connect("http://www.saudisale.com/SS_a_mpg.aspx").get();
Elements script = doc.select("script") ;

for(Element elementary :doc.select("table"))
{
System.out.println(""+elementary.select("tbody").select("tr").select("td").select("input").attr("onClick")+"");

样本输出：

window.open('http://saudisale.com/arPrivatePage.aspx?id=21871638','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');
window.open('http://saudisale.com/arPrivatePage.aspx?id=21871638','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');
window.open('http://saudisale.com/arPrivatePage.aspx?id=21871638','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');
window.open('http://ads.saudisale.com/dyaralez.html ','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');
window.open('http://ads.saudisale.com/dyaralez.html ','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');


window.open('http://ads.saudisale.com/dalel.html','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');

window.open('http://ads.saudisale.com/dalel.html','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');
    window.open('SS_a_car.aspx?carid=37240','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');
    window.open('SS_a_car.aspx?carid=37240','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');

基于Jsoup不支持javascript的事实，因此我必须执行一些手动Java代码才能将window.open（hyperlink）javascript代码转换为绝对超链接

例如，以下输出JavaScript代码必须进行转换

window.open('http://saudisale.com/arPrivatePage.aspx?id=21871638','_blank','channelmode=1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1')

至：http :
//saudisale.com/arPrivatePage.aspx?id=21871638

和

window.open('SS_a_car.aspx?carid=37149','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');

前往
http://www.saudisale.com/SS_a_car.aspx?carid=37149

有人可以指导我如何使用JAVA完成此任务吗？

Answer 1

使用正则表达式。这将做您想要的：

String input = "window.open('http://saudisale.com/arPrivatePage.aspx?id=21871638','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1');";

String regex = "window.open\\(['\"]*(.*?)(\\s*['\"]*,.*?)";
Pattern pattern = Pattern.compile(regex); 
Matcher matcher = pattern.matcher(input);
while (matcher.find()) {

    String output = (matcher.group().replaceAll(regex, "$1"));
    System.out.println(output);
}

最后两个URL是 相对的
，因此您必须按照此处所述将它们转换为绝对URL 。
