java - RuneScape 私有(private)服务器 - 缓存下载器

Question

我确实有一个 RuneScape 私有(private)服务器，并且我确实有一个客户端。

我正在尝试制作一个网络客户端，我已经做到了，但由于某种原因它从我的网站下载缓存并保留在cache.zip中。它不会解压，只是下载到我创建的位置。我很困惑，需要帮助来解决这个问题，因为我向我的成员(member)保证今晚会上线。

这是下载缓存后文件夹的样子。

应该将其中的文件提取到文件夹中。

这是我的CacheDownloader.java

您正在运行哪个版本？...

例如，在 718 Web 客户端中，您无需执行任何与缓存相关的操作!
