有人能帮我吗,还是不可能 JSoup正在解释HTML。
元素的内容包含JavaScript,因此JSoup无法解释
元素中的内容
看起来
元素的内容是用JSON格式化的。因此,您可以使用JSoup访问
元素的内容,然后尝试将该字符串放入JSON解释库中。如果你想深入了解这一点,请看这里:
如果这是一次性的,并且您可以相信
元素的内容不会改变太多,那么您也可以使用正则表达式来获得所需的部分。但是,我建议使用JSON库
public class JsoupCrawler {
public static void main(String[] args) {
try {
Document doc = Jsoup.connect("https://example.com").userAgent("mozilla/17.0").get();
Elements temp = doc.select("script.name");
int i=0;
for (Element nameList:temp) {
i++;
System.out.println(i+ " "+ nameList.getElementsByTag(" ").first().text() );
}
}
catch (IOException e) {
ex.printStackTrace();
}
}
}
