java - 面临 HtmlUnitDriver 的问题

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");

但是我遇到了以下异常。

Caused by: com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot find function aa in object [object Object].

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

异常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。

您需要显式启用它，然后尝试导航该 URL试试这个，它应该可以工作。

HtmlUnitDriver driver = new HtmlUnitDriver(true);

True --> 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。请查看此链接以了解更多详细信息。
