如何告诉htmlunit忽略某些错误

我目前正在尝试使用HtmlUnit。我想填写一份表格然后提交。但是这会导致错误，这似乎是由文件不可访问导致的，导致连接重置被抛出。我该如何抑制这一点，因为考虑到整个网站的加载过程，这并不重要？它似乎并没有影响程序，但是，我只是想让它变得沉默。如何告诉htmlunit忽略某些错误

发现的HtmlUnit一个bug在您的应用程序：一个JavaScript文件不可用。如果此文件应该可用，请将其提供。如果此文件没有任何用途，请删除对其的引用。测试的重点是检测并修复bug，而不是忽略它们。 – 2012-04-05 11:10:52

我知道这一点，但目前我只是在不具备远程访问权的不同网站上尝试使用它。 – Sim 2012-04-05 11:19:03

请尝试以下

webClient.setThrowExceptionOnFailingStatusCode(false);

，应当予以受理的404（未找到）错误状态。

nope，仍然是相同的错误仍然抛出 – Sim 2012-04-05 11:30:53

我想这是一个服务器错误，考虑到它的连接重置。你为什么不把它放在try catch块中，并且优雅地处理它？ – 2012-04-05 11:39:11

我能否抓住它，因为我的程序在打印堆栈跟踪后继续完美 – Sim 2012-04-05 11:58:23

您可以使用HttpUnitOptions.setScriptingEnabled(true);在HttpUnit的 和禁用javascript还取决于你的日志记录设置HttpUnitOptions.setExceptionsThrownOnScriptError(false);

[this]（http://httpunit.sourceforge.net/doc/api/com/meterware/httpunit/HttpUnitOptions.html）包是未知的，我如何获得HttpUnitOptions类/实例？ – Sim 2012-04-05 12:53:31

这实际上来自com.meterware.httpunit.HttpUnitOptions;所以你需要在调用HttpUnitOptions.setScriptingEnabled（true）之前下载httpunit jar; – Brijesh 2012-04-13 07:01:17

这是如何引用HtmlUnit的？ – Yura 2014-05-28 14:40:19

HtmlPage.loadExternalJavaScriptFile()将随时登录这个错误。您需要禁用该页面的日志记录，或更改阈值。

例如，如果你使用log4j的，你可以设置属性log4j.logger.com.gargoylesoftware.htmlunit.html.HtmlPage = FATAL

然而，这将隐藏登录HtmlPage所有错误的日志记录。

在使用jkd1.7.0_3编译后运行Jenkins的测试工具时，我遇到了类似的错误。回到JDK1.6.0_30解决了这个问题。

实例化的HtmlUnit DRIVER如下：

驱动=新SilentHtmlUnitDriver（能力）;

添加如下嵌套类（在同一个类实例化你的驱动程序）：

  protected class SilentHtmlUnitDriver extends HtmlUnitDriver { 
       SilentHtmlUnitDriver() { 
        super(); 
        this.getWebClient().setCssErrorHandler(new SilentCssErrorHandler()); 
        this.getWebClient().getOptions().setThrowExceptionOnFailingStatusCode(false); 
        this.getWebClient().getOptions().setThrowExceptionOnScriptError(false); 

      } 

      SilentHtmlUnitDriver(DesiredCapabilities capabilities) { 
       super(capabilities); 
       this.getWebClient().setCssErrorHandler(new SilentCssErrorHandler()); 
      } 
}

试试这个在对的HtmlUnit禁用恼人的警告（对不起，如果代码是不完全正确 - 我“从Clojure的翻译”，但我希望你得到的主要思想，至少）：

Import java.util.logging.Logger; 
Import java.util.logging.Level; 

Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);

看看Turning HtmlUnit Warnings off获取更多信息。那里有一个更复杂的解决方案，但这个简单的解决方案适用于我。

使用此：

LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog"); 
     java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF); 
     java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF);
