基本都要放弃了
springmvc 配置了htmlunit之后无法运行,都不能正常实例化webclient,但是突然想起来用maven应用程序测试一下
结果竟然就可以了.好吧,还是有希望的
大佬博客https://www.cnblogs.com/davidwang456/articles/8693050.html
main方法中
public static void main(String[] args) {
final WebClient webClient = new WebClient(BrowserVersion.CHROME);//新建一个模拟谷歌Chrome浏览器的浏览器客户端对象
webClient.getOptions().setThrowExceptionOnScriptError(false);//当JS执行出错的时候是否抛出异常, 这里选择不需要
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);//当HTTP的状态非200时是否抛出异常, 这里选择不需要
webClient.getOptions().setActiveXNative(false);
webClient.getOptions().setCssEnabled(false);//是否启用CSS, 因为不需要展现页面, 所以不需要启用
webClient.getOptions().setJavaScriptEnabled(true); //很重要，启用JS
webClient.setAjaxController(new NicelyResynchronizingAjaxController());//很重要，设置支持AJAX
HtmlPage page = null;
try {
page = webClient.getPage("http://ent.sina.com.cn/film/");//尝试加载上面图片例子给出的网页
} catch (Exception e) {
e.printStackTrace();
} finally {
webClient.close();
}
webClient.waitForBackgroundJavaScript(30000);//异步JS执行需要耗时,所以这里线程要阻塞30秒,等待异步JS执行结束
String pageXml = page.asXml();//直接将加载完成的页面转换成xml格式的字符串
//TODO 下面的代码就是对字符串的操作了,常规的爬虫操作,用到了比较好用的Jsoup库
Document document = Jsoup.parse(pageXml);//获取html文档
List<Element> infoListEle =
document.getElementById("feedCardContent").
getElementsByAttributeValue("class", "feed-card-item");//获取元素节点等
infoListEle.forEach(element -> {
System.out.println(element.getElementsByTag("h2").first().getElementsByTag("a").text());
System.out.println(element.getElementsByTag("h2").first().getElementsByTag("a").attr("href"));
});
System.out.println("Hello World!");
没写为何这样区
所以我又用f12检查了一下
大概就是这样一个获取路线
