我目前正在尝试 HtmlUnit。我想填写表格然后提交。但这会导致错误，这似乎是由无法访问的文件引起的，从而导致抛出连接重置。我该如何抑制这种情况，因为考虑到整个网站的加载过程，这并不重要？不过，它似乎不会影响程序，我只是希望它被静音。

尝试以下

webClient.setThrowExceptionOnFailingStatusCode(false);

它应该处理 404（未找到）错误状态。

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 htmlUnit 驱动程序如下：

driver = new SilentHtmlUnitDriver(capabilities);

将以下内容添加为嵌套类（在您实例化驱动程序的同一类中）：

         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());
            }
}

试试这个来禁用 HtmlUnit 中烦人的警告（对不起，如果代码不太正确 - 我从 Clojure “翻译”了它，但我希望你至少能明白主要思想）：

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

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

查看关闭 HtmlUnit 警告以获取更多信息。那里有一个更复杂的解决方案，但这个简单的解决方案对我有用。

HtmlPage.loadExternalJavaScriptFile()将始终根据您的日志记录设置记录此错误。您需要禁用页面的日志记录，或更改阈值。

例如，如果你使用 log4j，你可以设置属性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。

用这个：

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);

您可以使用HttpUnitOptions.setScriptingEnabled(true);禁用HttpUnit中的 javascript 以及HttpUnitOptions.setExceptionsThrownOnScriptError(false);
