final WebClient webClient = new WebClient(); final HtmlPage page = webClient.getPage("http://survey-creator.appspot.com/getSurvey");

推荐答案

HtmlUnit并不是真正的公正". HTML解析器.这是一种程序化的网络浏览器.旨在使用Java语言以编程方式浏览网页和/或填写Web表单.如果您的唯一目的是将HTML作为字符串获取，请使用真正的HTML解析器.为此，我可以推荐 Jsoup .

HtmlUnit is not really "just" a HTML parser. It's kind of a programmatic webbrowser. It's intented to surf through web pages and/or fill out web forms programmatically using Java language. If your sole purpose is to get the HTML as a String, use a real HTML parser. I can recommend Jsoup for this.

String html = Jsoup.connect("http://stackoverflow.com").get().html();

就是这样.但是，它可以做的还远远不止这些，例如选择感兴趣的元素.

That's it. It can however do much more than that, such as selecting elements of interest.
