Question

考虑以下html文件a.html

<html>
    <frameset>
       <frame src="frame_a.html">
    </frameset>
</html>

frame_a.html是以下

<html>
    <body>
       aaaaaa
    </body>
</html>

以下代码：

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.List;

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.FrameWindow;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class TestFramset {
public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException, InterruptedException {
WebClient client = new WebClient(BrowserVersion.FIREFOX_17);
client.getOptions().setJavaScriptEnabled(true);
client.getOptions().setRedirectEnabled(true);
client.getOptions().setThrowExceptionOnScriptError(true);
client.getOptions().setCssEnabled(true);
client.getOptions().setUseInsecureSSL(true);
client.getOptions().setThrowExceptionOnFailingStatusCode(false);
HtmlPage page = client.getPage("file:///...a.html");
System.out.println("page as text will give nothing:"+page.asText());
System.out.println("recursive function will give:"+getText(page));
}

public static String getText (HtmlPage page) {
    String text = page.asText();
    List<FrameWindow> frames = page.getFrames();
    for (FrameWindow frame:frames) {
        text += getText((HtmlPage) frame.getEnclosedPage());
    }
    return text;
}

}

将提供输出

页面，因为文字不会提供任何内容：

递归函数将给出：aaaaaa

我的问题是，如果page.asText函数不返回帧的文本这一事实是理想的，如果我以递归的方式获取帧的文本是最好的方式

如何用htmlunit打印帧的文本
