如何告訴htmlunit忽略某些錯誤

我目前正在嘗試使用HtmlUnit。我想填寫一份表格然後提交。但是這會導致錯誤，這似乎是由文件不可訪問導致的，導致連接重置被拋出。我該如何抑制這一點，因爲考慮到整個網站的加載過程，這並不重要？它似乎並沒有影響程序，但是，我只是想讓它變得沉默。如何告訴htmlunit忽略某些錯誤

發現的HtmlUnit一個bug在您的應用程序：一個JavaScript文件不可用。如果此文件應該可用，請將其提供。如果此文件沒有任何用途，請刪除對其的引用。測試的重點是檢測並修復bug，而不是忽略它們。 – 2012-04-05 11:10:52

我知道這一點，但目前我只是在不具備遠程訪問權的不同網站上嘗試使用它。 – Sim 2012-04-05 11:19:03

請嘗試以下

webClient.setThrowExceptionOnFailingStatusCode(false);

，應當予以受理的404（未找到）錯誤狀態。

nope，仍然是相同的錯誤仍然拋出 – Sim 2012-04-05 11:30:53

我想這是一個服務器錯誤，考慮到它的連接重置。你爲什麼不把它放在try catch塊中，並且優雅地處理它？ – 2012-04-05 11:39:11

我能否抓住它，因爲我的程序在打印堆棧跟蹤後繼續完美 – Sim 2012-04-05 11:58:23

您可以使用HttpUnitOptions.setScriptingEnabled(true);在HttpUnit的 和禁用javascript還取決於你的日誌記錄設置HttpUnitOptions.setExceptionsThrownOnScriptError(false);

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

這實際上來自com.meterware.httpunit.HttpUnitOptions;所以你需要在調用HttpUnitOptions.setScriptingEnabled（true）之前下載httpunit jar; – Brijesh 2012-04-13 07:01:17

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

HtmlPage.loadExternalJavaScriptFile()將隨時登錄這個錯誤。您需要禁用該頁面的日誌記錄，或更改閾值。

例如，如果你使用log4j的，你可以設置屬性log4j.logger.com.gargoylesoftware.htmlunit.html.HtmlPage = FATAL

然而，這將隱藏登錄HtmlPage所有錯誤的日誌記錄。

在使用jkd1.7.0_3編譯後運行Jenkins的測試工具時，我遇到了類似的錯誤。回到JDK1.6.0_30解決了這個問題。

實例化的HtmlUnit DRIVER如下：

驅動=新SilentHtmlUnitDriver（能力）;

添加如下嵌套類（在同一個類實例化你的驅動程序）：

  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()); 
      } 
}

試試這個在對的HtmlUnit禁用惱人的警告（對不起，如果代碼是不完全正確 - 我「從Clojure的翻譯」，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獲取更多信息。那裏有一個更復雜的解決方案，但這個簡單的解決方案適用於我。

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);
