500 Internal Server Error with icloud

[Ahmad AlTwaijiry]

Hello everyone

Im trying to get all events from icloud but it seems I'm doing it in a wrong way! 

My request:

REPORT /__ID__/calendars/963311E1-D1CB-4C1D-9AF8-9543F2D5EF3E/ HTTP/1.1

Authorization: Basic wNSQwwNSQwwNSQwwNSQwwNSQwwNSQwwNSQwwN==

<c:calendar-query xmlns:d="DAV:" xmlns:c="urn:ietf:params:xml:ns:caldav"><d:prop><c:calendar-data /></d:prop></c:calendar-query>

The response is always:

I'm not able to understand what is missing ?

Hi Admad,

iCloud does not run sabredav, but judging from your request.. you're at least missing the 'filter' element. This element is required for calendar-query.

See:
http://tools.ietf.org/html/rfc4791#section-9.5

for a reference.

Hi Evert

I know icloud not using sabredav, I'm just using sabredav as a library for my client.

And as per the page (http://sabre.io/dav/building-a-caldav-client/) :

Downloading objects

Now we download every single object in this calendar. To do this, we use a REPORT method.

REPORT /calendars/johndoe/home/ HTTP/1.1

Depth: 1

Prefer: return-minimal

Content-Type: application/xml; charset=utf-8

<c:calendar-query xmlns:d="DAV:" xmlns:c="urn:ietf:params:xml:ns:caldav">

   <d:prop>

       <d:getetag />

       <c:calendar-data />

   </d:prop>

   <c:filter>

       <c:comp-filter name="VCALENDAR" />

   </c:filter>

</c:calendar-query>

But as I said it's not working, only if I use the below xml with icloud it will work:

Method: PROPFIND

<d:propfind xmlns:d="DAV:"><d:prop><d:getetag/></d:prop></d:propfind>

Not sure if this is special case with icloud or I misunderstood the document.

[Evert Pot]

 It does sound familiar that iCloud does not support every type or request.
Remember that apple does not advertise to support CalDAV. They use CalDAV technology, but it's not at all an open server and they can shut you down when they feel like it.

However, your original request did not have the filter element, so that comment still applies. If adding the filter element does not fix it, then it's possible that iCloud simply does not support that operation.

[Ahmad AlTwaijiry]

Hi

even with filter it will return 500 internal error.

as you said, it seems they are not supporting all requests.

Thanks
