Question

我遇到与问题Call getPage from htmlunit WebClient with JavaScript disabled and setTimeout set to 10000 waits forever中描述的问题相同的问题。

那里只有一个相关（复杂）可能的答案（by theytoo）。所以我想知道是否：

有人有更简单的答案吗？
有人可以验证解决方案有效吗？

Answer 1

我使用的代码：

package main;

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

import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;

public class Test {

    public static void main(final String[] args) {
        final WebClient webClient = new WebClient();
        webClient.setTimeout(1000);
        try {
            System.out.println("Querying");
            webClient.getPage("http://www.google.com");
            System.out.println("Success");
        } catch (final FailingHttpStatusCodeException e) {
            System.out.println("One");
            e.printStackTrace();
        } catch (final MalformedURLException e) {
            System.out.println("Two");
            e.printStackTrace();
        } catch (final IOException e) {
            System.out.println("Three");
            e.printStackTrace();
        } catch (final Exception e) {
            System.out.println("Four");
            e.printStackTrace();
        }
        System.out.println("Finished");
    }

}

输出（删除所有CSS和JS警告）：

Querying
Success
Finished

将超时从1000更改为1（我在不到1毫秒内赢得了谷歌）：

Querying
Three

    at com.gargoylesoftware.htmlunit.WebClient.getPage(WebClient.java:358)
    at main.Test.main(Test.java:17)
Finished

结论：我无法重现它并且按预期工作

如何从HtmlUnit WebClient调用getPage并让setTimeout不要永远等待？
