Question

我正在尝试使用HTMLUnit获取此页面，但似乎HTMLUnit会进行无限循环并崩溃。

我一直试图找到原因，但我放弃了。我试过了：

从SVN HTMLUnit获取最新代码
使用不同的浏览器
尝试调试，但我找不到原因。

如果我使用 webClient.setJavaScriptEnabled（假）;

我可以访问该网站，但不会执行重要的脚本。所以，问题在于JavaScript。

这是一个运行循环的示例代码：

String url = "http://www.tjpe.jus.br/processos/consulta1grau/oleConsultaProcesso.asp?
nume=00123335620128170990&modalidade=6";

    final List collectedAlerts = new ArrayList();
    final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_17);
    webClient.setThrowExceptionOnScriptError(false);
    webClient.setAlertHandler(new CollectingAlertHandler(collectedAlerts));
    webClient.waitForBackgroundJavaScript(10000);
    webClient.waitForBackgroundJavaScriptStartingBefore(10000);
    try {
        final HtmlPage page1 = webClient
        .getPage(url);

        page1.asXml();
    } catch (FailingHttpStatusCodeException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

这是错误：

如果有人能帮助我，请感谢。

您尝试访问的网址似乎有一些Javascript错误。尝试

webClient.setThrowExceptionOnScriptError(false);

HTMLUnite无限循环stackoverflow
