如何告诉htmlunit忽略某些错误

Question

我目前正在尝试使用HtmlUnit。我想填写表格，然后提交。但是这会导致错误，这似乎是由文件无法访问引起的，这会导致连接重置被抛出。 我怎么能压制这一点，因为考虑到整个网站的加载过程，这不是至关重要的？ 但它似乎并没有影响该计划，我只是想让它沉默。

Answer 1

尝试以下

webClient.setThrowExceptionOnFailingStatusCode(false);

它应该处理404（未找到）错误状态。

Answer 2

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

Answer 3

HtmlPage.loadExternalJavaScriptFile()将始终记录此错误，具体取决于您的日志记录设置。您需要禁用页面的日志记录，或更改阈值。

例如，如果您使用的是log4j，则可以设置属性log4j.logger.com.gargoylesoftware.htmlunit.html.HtmlPage = FATAL

但是，这将隐藏 HtmlPage 中记录的所有错误的记录。

Answer 4

将htmlUnit驱动程序视为以下内容：

driver = new SilentHtmlUnitDriver（capabilities）;

添加以下作为嵌套类（在同一类中实例化驱动程序）：

         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());
            }
}

Answer 5

试试这个来禁用HtmlUnit中令人讨厌的警告（对不起，如果代码不是很正确 - 我＆＃34;翻译＆＃34;来自Clojure，但我希望你得到主要想法，至少）：

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

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

请查看Turning HtmlUnit Warnings off了解详情。那里有一个更复杂的解决方案，但这个简单的解决方案对我有用。

Answer 6

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);

Answer 7

您可以使用HttpUnitOptions.setScriptingEnabled(true);在 HttpUnit 中禁用javascript 还有HttpUnitOptions.setExceptionsThrownOnScriptError(false);
