Question

我使用下面的代码来获取Google搜索结果的前两页但我只能获取第一页（当搜索第2页时，它与第1页相同）

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlElement;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlTextInput;


/**
 * A simple Google search test using HtmlUnit.

public class Author_search {
    static final WebClient browser;

    static {
        browser = new WebClient();
        browser.setJavaScriptEnabled(false);
    }

    public static void main(String[] arguments) {
            searchTest();
    }

    private static void searchTest() {
        HtmlPage currentPage = null;

        try {
            currentPage = (HtmlPage) browser.getPage("http://www.google.com");
        } catch (Exception e) {
            System.out.println("Could not open browser window");
            e.printStackTrace();
        }
        System.out.println("Simulated browser opened.");

        try {
            ((HtmlTextInput) currentPage.getElementByName("q")).setValueAttribute("xxoo");
            currentPage = currentPage.getElementByName("btnG").click();
            System.out.println("contents: " + currentPage.asText());
            HtmlElement next = (HtmlElement)currentPage.getByXPath("//span[contains(text(), 'Next')]").get(0);
            currentPage = next.click();
            System.out.println("contents: " + currentPage.asText());
        } catch (Exception e) {
            System.out.println("Could not search");
            e.printStackTrace();
        }
    } 
}

任何人都可以告诉我如何解决这个问题吗？

顺便说一下：

如何使用htmlunit更改google中的语言设置？任何方便吗？
htmlunit是否将html视为“firebug” firefox，或者只是将其视为“file-＆gt; save”中的文本。在我的意见，我相信它对待它就像是一个探险家，我是对的吗？

Answer 1

我已取代：

HtmlElement next = (HtmlElement)currentPage.getByXPath("//span[contains(text(),'Next')]").get(0);
currentPage = next.click();

<强>与

HtmlAnchor nextAnchor =currentPage.getAnchorByText("Next");
currentPage = nextAnchor.click();

如何在谷歌上使用htmlunit获取“下一页”
