我做错了什么？
您正在尝试 PUT 将事件添加到日历 homeset 集合中：
PUT https://p49-caldav.icloud.com
/10430699202 # user scope
/calendars # calendar home
/??? # calendar
/ee451a47-c242-40c1-b295-4f1251a5d0cd.ics # event
日历 homeset 包含日历，而不是事件。所以下一步是选择您要将活动放入的日历（例如 default calendar）。
您可以在 homeset 上用另一个 PROPFIND Depth:1 列出可用的日历（和待办事项列表）。
