我正在尝试在www.meetme.com上发送消息,但无法弄清楚如何做到这一点。我可以在评论区域中输入消息,但单击“发送”按钮不会执行任何操作。我究竟做错了什么?当我登录并按下登录按钮时,页面确实会发生变化,一切都很好。有人有任何想法或线索吗?
HtmlPage htmlPage = null;
HtmlElement htmlElement;
WebClient webClient = null;

在不了解您正在访问的网页的情况下,您无法在禁用JavaScript的情况下执行AJAX请求。如果更改不会导致成功,那么您将不得不继续调试,但要确保启用了JavaScript。
此外,请确保您使用的是HtmlUnit 1.12并更新代码中所有已弃用的方法。
顺便说一下,我还建议关闭JavaScript警告。检查this answer,了解如何做到这一点。
