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:
答案 0 :(得分:3)
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

结论:我无法重现它并且按预期工作
