Question

我正在编写一段简单的Java代码，用于检查外部IP并更新我的DNS条目（如果已更改）。

我使用NetBeans和HTMLunit。代码的第一部分工作正常。我的代码从WhatIsMyIp.com获取正确的外部IP地址

第二部分涉及登录我的DNS提供商网页（fastname.no），如下所示。

>  
>   public void LoginToDNS(HtmlPage LogInPage) throws Exception {
>     try (final WebClient webClient = new WebClient()) {
> 
>                     //get the webpage data we're looking for
>                     // also get the buttons and textfields
>                     final List<?> forms = LogInPage.getForms();
>                     final HtmlForm form = LogInPage.getFormByName("form1");        
>                     final HtmlTextInput UsernameField = form.getInputByName("username");        
>                     final HtmlPasswordInput PasswordField = form.getInputByName("password");
>                     final HtmlButton submit_button = form.getButtonByName("submit");
> 
>                     // Set the Username and pasword
>                     UsernameField.setValueAttribute("myusername");
>                     PasswordField.setValueAttribute("mypassword");
> 
>                     // submit the form by clicking the button and get back the control panel page
>                     final HtmlPage DNSPage = submit_button.click();
>                     CheckDNSEntries(DNSPage);
>                     
>         }
>     }

虽然我可以看到我已正确登录（我知道，因为页面标题更改为正确的页面标题），我看到一个SSL错误，结果网页不是我想要的。

当我按下Submit_button时，我看到来自htmlunit的调试器上有很多错误。（见下文）

我不太确定这是否是处理JavaScript的HTMLunit问题，或者只是我的代码。是否有更好的解决方案，我可以使用而不是HTMLunit，这将使我更快地走到哪里？毕竟我认为我想完成的任务相对简单。

尝试通过添加以下内容启用SSL：

webClient.getOptions().setUseInsecureSSL(true);

您可以找到更多文档here。

修改为了隐藏HtmlUnit日志，您必须添加以下内容：

LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog"); java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF); java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF);

HTMLunit浏览器自动化导致SSL错误
