java - 如何让 HtmlUnit 在 Android 下工作？

Question

这是我的代码:

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

final WebClient webClient = new WebClient();
final HtmlPage startPage = webClient.getPage("http://htmlunit.sf.net");

这是我得到的错误:

我几乎包含了每个 jar，同时删除了几个，因为它们是导致 Eclipse 崩溃的原因。我想我已经包含了这两行代码所需的一切。

在实践中，HtmlUnit 在 Android 上工作时遇到了困难。

如有任何建议，我们将不胜感激。

Answer 1

如果您只是想获得一个页面并填写一些表格并提交，jsoup是一个很好的选择。

我让它在 android 中正常工作，只需将 jsoup.jar 添加到 libs 文件夹即可。

这是一个简单的例子

Document doc = Jsoup.connect("http://jsoup.org/")
            .timeout(4000)
            .get();

或者提交数据的例子

Connection.Response res = Jsoup.connect("http://example.org")
                .data("q", username, "password", password) 
                .method(Method.GET)
                .execute();

Document doc = res.parse();
System.out.println(doc);
