HtmlUnit ScriptException错误

Question

我正在使用HtmlUnitDriver，＆amp;这是我的代码。

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

我得到以下异常：

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

要求提出许多问题来引用这类问题。引发ScriptException是因为您的javascript中存在语法错误。大多数浏览器都会设法解释JS甚至出现某种错误，但HtmlUnit在这个意义上有点不灵活。

您的选择是：

1. 纠正JS代码
2. 在WebClient
中停用JS
3. 不要使用HtmlUnit。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

我和liveperson mTag.js有同样的错误

问题在于压缩的mTag.js响应。

有几种解决方法：

1. 用明确的mTag.js替换压缩的mTag.js（需要LivePerson支持）
2. 使用'真正的'Selenium WebDriver（Firefox驱动程序或类似代码）

Answer 3

_webClient.getOptions().setThrowExceptionOnScriptError(false);

适用于这种不正确的JS场景。
