问题
I'm trying to PUT an event on iCloud calendar using CalDav. After several proper requests and responses and getting the user principal and calendars, when i try to PUT an event, the server returns Unauthorized error.
Here's the network log from fiddler:

The server redirects me and removes the authorization header causing the unauthorized error:

When I targeted the redirecting URL encountered another error:

What am I doing wrong?
回答1:
You are trying to PUT an event into the calendar homeset collection:
PUT https://p49-caldav.icloud.com
/10430699202 # user scope
/calendars # calendar home
/??? # calendar
/ee451a47-c242-40c1-b295-4f1251a5d0cd.ics # event
A calendar homeset contains calendars, not events. So the next step is selecting the calendar you want to put your event into (e.g. the default calendar).
You can list the available calendars (and todo lists) with another PROPFIND Depth:1 on the homeset.
