我一直在测试HTMLUnit,我想知道我是否能从某些网站中获得价值。
尝试使用https://rsbuddy.com/exchange?id12934之后,我似乎得到了一些503错误。
似乎与CloudFlare的IUAM存在某种冲突。
我环顾四周,找到了this site,其中有人遇到了和我一样的问题。社区告诉海报,HTMLUnit可以解决他们的问题,但最终似乎没有解决问题,但是没有解决方案。
目前我的代码看起来很简单:
final WebClient webClient = new WebClient();
final HtmlPage page = webClient.getPage("https://rsbuddy.com/exchange?id12934");
System.out.println(page.asXml());
输出:

有没有办法使用HTMLUnit来连接到网站?
答案 0 :(得分:1)
有一段时间等待检查浏览器版本,我相信如果你:
WebClient webClient = new WebClient(BrowserVersion.CHROME);
首先设置浏览器版本。然后运行该行以获取页面:
final HtmlPage page = webClient.getPage("https://rsbuddy.com/exchange?id12934");
后面几个选项:
我。设置等待的时间:
webClient.waitForBackgroundJavaScript(5000);
或
while(page.asText().contains("Checking your browser before accessing")){
webClient.waitForBackgroundJavaScript(100);
}
II。使用Thread.sleep()而不是等待JS:
Thread.sleep(2000);// replace with this code.
最后打印出来:
System.out.println(page.asXml());
