How to get web page that contain errors with HtmlUnit?

本文关键字：HtmlUnit 错误 网页 包含 何获取 获取      更新时间：2023-09-26

我正试图使用HtmlUnit 2.15 API在Java程序中访问此Ajax页面，但尝试获取该页面时失败。我认为原因是网站请求位于此处的这个损坏/丢失的文件。

我的代码：

public class HtmlUnitExample {
    public static void main(String[] args) throws Exception, FailingHttpStatusCodeException, MalformedURLException, IOException, InterruptedException {
        WebClient webClient = new WebClient(BrowserVersion.FIREFOX_24);
        webClient.getOptions().setTimeout(120000);
        webClient.waitForBackgroundJavaScript(60000);
        webClient.getOptions().setRedirectEnabled(true);
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
        webClient.getOptions().setThrowExceptionOnScriptError(false);
        webClient.getOptions().setCssEnabled(true);
        webClient.getOptions().setUseInsecureSSL(true);
        webClient.getOptions().setDoNotTrackEnabled(true);
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());
        String url = "http://www.santanderuniversidades.com.br/JuriPopular/index.aspx?idprojeto=16";
        final HtmlPage page = (HtmlPage) webClient.getPage(url); //Fails here
        System.out.println(page.asXml());
    }
}

错误消息：

    at HtmlUnitExample.main(HtmlUnitExample.java:42)//getPage line

css的页面链接：

<link href='/JuriPopular/App_Themes/estilo/css.axd?files=jPages.css,estilo.css,jquery.fancybox.css' type='text/css' rel='stylesheet' />

调用丢失字体文件的css：

@font-face{font-family:'DigitalDotRoadsign';
src:url('fonts/DigitalDotRoadsign.eot');
src:url('fonts/DigitalDotRoadsign.eot?#iefix') format('embedded-opentype'),
url('fonts/DigitalDotRoadsign.woff') format('woff'), //call missing file
url('fonts/DigitalDotRoadsign.ttf') format('truetype'),
url('fonts/DigitalDotRoadsign.svg#svgDigitalDotRoadsign') format('svg');
font-weight:normal;
}

这是我问题的根源吗？如果是这样的话，有没有办法避免呢？也许忽略/消除了问题的原因？

实际上，为了解决这个问题，我只启用了cookie。我想加载页面是必要的。

代码：

webClient.getCookieManager().setCookiesEnabled(true);
