我一直坚持使用HtmlUnit获取基于JavaScript的动态内容。我期待从页面获得(Signin,注册html内容)。使用以下代码,我只获取静态内容。
我是HtmlUnit的新手。任何帮助将受到高度赞赏。
String strURL = "https://www.checkmytrip.com" ;
java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);
java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);
final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_31);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getCookieManager().setCookiesEnabled(true);
webClient.waitForBackgroundJavaScript(60 * 1000);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
HtmlPage myPage = ((HtmlPage) webClient.getPage(strURL));
String theContent = myPage.getWebResponse().getContentAsString();
System.out.println(theContent);
答案 0 :(得分:5)
两点:
您应该使用myPage.asText()或.asXml()代替,因为getWebResponse()会在不执行JavaScript的情况下返回原始内容。
String strURL = "https://www.checkmytrip.com" ;
java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);
java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);
try (final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_31)) {
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
HtmlPage myPage = ((HtmlPage) webClient.getPage(strURL));
webClient.waitForBackgroundJavaScript(10 * 1000);
String theContent = myPage.asXml();
System.out.println(theContent);
}
