java - 如何获取java中查看源代码的Javascricpt后生成的html？ [复制]

Question

我曾尝试过 Htmlunit，但它不起作用，所以你可以帮助我使用 API 或任何其他我可以研究并获得解决方案的解决方案。谢谢

import com.gargoylesoftware.htmlunit.BrowserVersion;
import java.io.IOException;
import java.net.MalformedURLException;
import java.util.List;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class GetPageSourceAfterJS {
    public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException {

        java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF); /* comment out to turn off annoying htmlunit warnings */
        WebClient webClient;
        webClient = new WebClient(BrowserVersion.CHROME);
        webClient.getOptions().setJavaScriptEnabled(true);
        //System.out.println("Loading page now: "+url);
        HtmlPage page = webClient.getPage("http://www.thehindu.com/");
        webClient.waitForBackgroundJavaScript(30 * 1000); /* will wait JavaScript to execute up to 30s */

        String pageContent = page.asText();
        System.out.println("pageContent");

        //get divs which have a 'class' attribute of 'bucket'
       // List<?> buckets = page.getByXPath("//div[@class='bucket']");
       // System.out.println("Found "+buckets.size()+" 'bucket' divs.");

        //System.out.println("#FULL source after JavaScript execution:\n "+pageAsXml);
    }
} can u tell me why this failing to run

如果DOM生成的元素有ID，可以通过

<someVariable> = document.getElementById(id);

然后得到<someVariable>.outerHTML。
