php - 如何从使用 php 选择的表单 ical - 数据库的位置获取可用性状态？

Question

我在一个组织和一个神学院工作，该神学院也可供其他组织使用。我需要的是显示网站中的其他组织，如果房间被保留或没有。这些信息可以从 ical 数据库中选择，但我怎样才能得到它们呢？

请帮我

ical._______.com/principals/locations/_____sog1sr/

ical._______.com/principals/__uids__/4B2F63D6-1906-4115-A9C9-DC888E53A44D/

那两个链接有相同的内容，来自ical数据库！

我现在的问题是，我可以通过哪个推荐获得信息？如果我添加/calendar-proxy-read，我就会回到同一页面这就是数据库向我展示的内容：

看起来您正在使用 Darwin 日历服务器。

您将需要编写一个 CalDAV 客户端来执行将返回此信息的 API 调用。您需要学习的三个主要文件是：
