Java使用HtmlUnit抓取js渲染頁面

需求：

需要采集js渲染的頁面，有些網站的頁面是js渲染的

實現：

基於HtmlUnit實現：

public static void getAjaxPage() throws Exception{
    WebClient webClient = new WebClient();
    webClient.setJavaScriptEnabled(true);
    webClient.setCssEnabled(false);
    webClient.setAjaxController(new NicelyResynchronizingAjaxController());
    webClient.setTimeout(Integer.MAX_VALUE);
    webClient.setThrowExceptionOnScriptError(false);
    HtmlPage rootPage = webClient.getPage("http://tt.mop.com/read_14304066_1_0.html");

    System.out.println(rootPage.asXml());
}

maven依賴：

<dependency>
    <groupId>net.sourceforge.htmlunit</groupId>
    <artifactId>htmlunit-core-js</artifactId>
    <version>2.9</version>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>net.sourceforge.htmlunit</groupId>
    <artifactId>htmlunit</artifactId>
    <version>2.9</version>
    <scope>compile</scope>
</dependency>

說明：

Nutch插件：nutch-htmlunit用於替換Nutch自身的Http Fetch組件
