HtmlUnit ScriptException错误

Question

我使用的是HtmlUnitDriver，下面是我的代码。

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

我得到了以下异常：

Caused by: com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: SyntaxError: missing ; before statement (http://sales.liveperson.net/hcp/html/mTag.js?site=7824460#1(eval)#1)

请帮我解决这个问题。

Answer 1

关于这类问题，人们提出了许多问题。引发ScriptException是因为您的javascript中存在语法错误。大多数浏览器都设法解释JS，即使有一些错误，但HtmlUnit在这种意义上有点僵化。

您可以选择：

更正JS代码，并在WebClient

• Don't HtmlUnit中禁用JS。使用具有更好JS支持的不同框架，例如PhantomJS (注意，它不是基于Java的框架)

Answer 2

_webClient.getOptions().setThrowExceptionOnScriptError(false);

在这个错误的JS场景中工作。

Answer 3

我在liveperson mTag.js上也遇到了同样的错误。

问题出在压缩的mTag.js响应上。

有几种解决方法：

1. 将压缩的mTag.js替换为清晰的(需要LivePerson支持)
2. 使用真正的Selenium WebDriver (Firefox驱动程序或类似驱动程序)
