htmlunit爬取Ajax动态生成的网页获取不到ajax出来的数据

WebClient mWebClient = new WebClient(BrowserVersion.CHROME);
mWebClient.getOptions().setUseInsecureSSL(true);
mWebClient.getOptions().setCssEnabled(true);
mWebClient.getOptions().setActiveXNative(true);
mWebClient.getOptions().setJavaScriptEnabled(true);
mWebClient.getOptions().setThrowExceptionOnScriptError(false);
mWebClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
mWebClient.getOptions().setRedirectEnabled(true);
mWebClient.getOptions().setTimeout(0);
mWebClient.setJavaScriptTimeout(0);
mWebClient.waitForBackgroundJavaScript(0);
mWebClient.setAjaxController(new NicelyResynchronizingAjaxController());

    final HtmlPage mHtmlPage = 
        mWebClient.getPage("http://localhost:8080/#main/observationAnalysis/performance/performanceGlobal");
    Thread.sleep(60000);

    ResponseUtils.renderText(response, mHtmlPage.asText());

抓包看下服务器返回的数据对不对，报什么错。你访问的网站是你自己内网的，这个还是需要你自己调试。

htmlunit对ajax的支持不太好，可以使用谷歌开源的一个基于google headless模式的puppeteer框架来爬页面
