Those are not errors, they are warnings.

这些不是错误，而是警告。

They are caused by HtmlUnit's JavaScript engine Mozilla's Rhinobeing unable to properly interpret some JavaScript code. (It is not as "good" as some other popular JS Engines.)

它们是由 HtmlUnit 的 JavaScript 引擎Mozilla 的 Rhino无法正确解释某些 JavaScript 代码引起的。（它不如其他一些流行的 JS 引擎“好”。）

You can turn those warnings off, here's how:

您可以关闭这些警告，方法如下：

public static void main(String[] args) throws Exception {
    // turn off htmlunit warnings
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);
    java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);

    WebClient webClient = new WebClient();
    HtmlPage page = webClient.getPage("http://stackoverflow.com");
    System.out.println(page.getTitleText());
}

Output:

输出：

Stack Overflow

在webClient浏览器中将启用 Javascript 和 CSS 设置为：

webClient.getOptions().setJavaScriptEnabled(false);
webClient.getOptions().setCssEnabled(false);

You can ON/ OFFby passint true or false parameters.

您可以ON/ OFFby passint true 或 false 参数。
