如何在Java程序中读取JavaScript输出文本

Question

Hi i am trying to read forbes.com 's thought of the day in my Java program. 嗨，我正在尝试在Java程序中阅读forbes.com关于当天的想法。 But in the view source of the webpage i am not getting the output rendered on the html page. 但是在网页的查看源中，我没有在html页面上呈现输出。 Any clues as to how to read the rendered output? 关于如何读取渲染输出的任何线索？

Heres the source code of website where i am reading the thoughts from. 这是我从中读取想法的网站的源代码。

<head>
    <script src="http://images.forbes.com/scripts/dart_forbes.js"></script>
    <script src="http://images.forbes.com/welcome/desktop/welcome_js.js?v=1.5"></script>
</head>
<body>
    <script language="JavaScript">
        forbes_dart.ad('thoughtx', '600x100');
    </script>
</body>

I have minimised and removed all clutter and kept it as basic as possible. 我已将所有杂物减至最少，并使其尽可能基本。

Heres the view source of the site 这是网站的查看源

<html>
    <head>
        <script src="./js/dart_forbes.js"></script>
        <script src="./js/welcome_js.js"></script>
    </head>
    <body>
        <script language="JavaScript">
            forbes_dart.ad('thoughtx', '600x100');
        </script>
    </body>
</html>

Here's my Java program 这是我的Java程序

public class extractor {

    public static void main(String args[]) throws Exception{
        extractor t = new extractor();
        t.connect();
    }

    public void connect() throws Exception {
        URL obj = new URL("http://localhost:8080/q2p/thought.html");
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        System.out.println(response.toString());
    }

}

Here's the program output 这是程序输出

<html>    <head>        <script src="./js/dart_forbes.js"></script>        <script src="./js/welcome_js.js"></script>    </head>    <body>        <script language="JavaScript">            forbes_dart.ad('thoughtx', '600x100');        </script>    </body></html>

Well after some help from meister_reineke heres the java code which works :) and solves the problem. 经过meister_reineke的一些帮助之后，这是可以工作的Java代码:)并解决了问题。

public class extractor {

    public void connect() throws Exception {

        WebClient webClient = new WebClient(BrowserVersion.CHROME);
        HtmlPage myPage = ((HtmlPage) webClient.getPage(obj));

        System.out.println(myPage.asText());
        webClient.closeAllWindows();
