如何从HtmlUnit WebClient调用getPage并让setTimeout不要永远等待? [英] How to call getPage from HtmlUnit WebClient and have setTimeout not wait forever?

问题描述

我遇到与问题那里只有一个相关(复杂)的可能答案(由他们).所以我想知道是否:

There is only one relevant (complicated) possible answer there (by theytoo). So I was wondering if:

1. 有人回答更简单吗?
2. 有人可以验证该解决方案是否有效吗?

推荐答案

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(已删除所有CSS和JS警告):

Output (removed all CSS and JS warnings):

Querying
Success
Finished

将超时时间从1000更改为1后(我不会在不到1毫秒的时间内打谷歌):

After changing timeout from 1000 to 1 (I won't hit google in less than 1 ms):

Querying
Three

结论:我无法复制它，并且按预期运行

Conclusion: I can't reproduce it and it works as expected
