Question

我正在使用HtmlUnitDriver打开链接。这是我的代码：

HtmlUnitDriver webDriver = new HtmlUnitDriver();
webDriver.get("some url here");

但是我得到了例外。

请指导我，如何解决这个问题。我使用的是selenium-java-2.24.1.jar，webdriver-common.jar。

Answer 1

Exception表示驱动程序在加载页面时遇到Javascript函数问题，默认情况下HTMLUNITDriver禁用Javascript。

您需要明确启用它，然后尝试导航URL 试试这个它应该有效。

HtmlUnitDriver driver = new HtmlUnitDriver(true);

真 - ＆gt;这里提到启用Java脚本。

此外，HtmlUnitDriver使用的javascript引擎与其他浏览器不同。请查看此链接以获取更多详细信息。

Answer 2

driver = new HtmlUnitDriver（true）;

再添加一行 -

java.util.logging.Logger.getLogger（ “com.gargoylesoftware”）setLevel（Level.OFF）;

Answer 3

您可能想尝试一下。

这对我来说很好。这是您可能希望对Java进行细微更改的Scala代码。

val  driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_3_6)
driver.setJavascriptEnabled(true)
driver.get(your_url)
driver.getTitle() must contain("Welcome")
