使用 JAVA 将 window.open（超链接）Javascript 代码转换为纯绝对 url

Question

我在使用 JAVA Jsoup 库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")+"");

示例输出：-

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，所以我不得不做一些手动java代码来转换window.open（超链接）javascript绝对超链接的代码

例如下面的输出JavaScript代码必须被转换

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

收件人： 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');

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

有人可以指导我如何使用 JAVA 完成这项任务吗？

Answer 1

使用正则表达式。这会做你想做的事：

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, ""));
    System.out.println(output);
}

您的最后两个网址是 相对网址，因此您必须按照 here.

所述将它们转换为绝对网址

Answer 2

对于亲戚 URl 我使用了这段代码。它工作正常。

String input2 = "window.open('SS_a_car.aspx?carid=37149','_blank','channelmode =1,scrollbars=1,status=0,titlebar=0,toolbar=0,resizable=1')";        

    URL baseURL = new URL("http://saudisale.com/");

    String regex = "window.open\(['\"]*(.*?)(\s*['\"]*,.*?)";
    Pattern pattern = Pattern.compile(regex); 
    Matcher matcher = pattern.matcher(input2);
    while (matcher.find()) {

        String output = (matcher.group().replaceAll(regex, ""));
        URL url = new URL( baseURL ,output);
        System.out.println(url);
    }
