我想从我的大学加载页面，以便我可以将等级直接拉入我的程序。我正在尝试使用HttpsURLConnection，但每当我拨打URL.openConnection并发送GET请求时，我都会返回一个没有有用信息的加载页面。URL.openConnection（）不会等待页面全部加载
如何完全加载页面，以便能够从实际页面而不是加载页面获取数据？
编辑： 我得到这个：

如果你可以在这里粘贴你通过'URL.openConnection'得到的东西，并指定你想从中得到什么，这将是有帮助的？具体来说，我的意思是代码和你得到的回应。 – kenshinji
您尝试连接的一面是否需要登录？如果是，你是否正确处理了http头和会话信息？ –
是啊需要登录 - 我想我正确处理它，但我不是100％确定。我编辑了我的帖子以包含我的'GET'方法。 – Shamsun
