HI

I am building an online appointments app which I would like to integrate with ical.

The biggest issue I'm having is that while I can get a script to connect and log in via CalDav, I can't get to a specific calendar in order to test adding & removing. Essentially I can connect to your iCal instance viahttps://cal.me.com/principals/users/blahblah@me.com/ and theusername / password however all this gives me is a directory overview page (perhaps for file storage?) and does not allow me to access any other folders as far as I can work out.

The problem seems to be that to access a calendar you need to use a specific url in a specific format but I can't seem to find that online.

Is there anyone out there that can help?

This list is focused on iCal Server as opposed to Mobile Me's services, but this question seems fairly generic... We (iCal Server) have a diagnostic tool called CalDAVClientLibrary, which provides an interactive CalDAV command-line shell - useful for exploring CalDAV services. When I connect to my mobile me calendar, I see: ./runshell.py --server https://cal.me.com/principals/users/dre@me.com/ User: dre Password: / > ls (no results) Against an iCal Server, the 'ls' would have displayed the server's document root: andre@xomg[CalendarServer/CalDAVClientLibrary]./runshell.py --server https://redacted.lompywickets.com User: dre Password: / > ls .calendarserver_version .well-known/ addressbooks/ admin/ calendars/ directory/ principals/ timezones webcal/ Digging around a bit, I think I have a method (but perhaps not the correct / expected method) to find the user's mobile me calendars. 1) Log in with CalDAVClientLibrary, get properties for the document root: andre@xomg[CalendarServer/CalDAVClientLibrary]./runshell.py --server https://cal.me.com User: dre@mac.com Password: / > props / OK Properties: {DAV:}acl-restrictions: {DAV:}creationdate: 2011-05-02T13:23:59Z {DAV:}current-user-principal: URL: /principals/users/1.9979107/ {DAV:}current-user-privilege-set: <Element '{DAV:}current-user-privilege-set' at 0x10e3852d0> {DAV:}displayname: tmp {DAV:}getcontentlength: {DAV:}getcontenttype: httpd/unix-directory {DAV:}getetag: "9E0001-1000-4DBF12DF" {DAV:}getlastmodified: Mon, 02 May 2011 13:23:59 GMT {DAV:}inherited-acl-set: {DAV:}principal-collection-set: URL: /principals/ {DAV:}resourcetype: <Element '{DAV:}resourcetype' at 0x10e387710> {DAV:}supported-privilege-set: <Element '{DAV:}supported-privilege-set' at 0x10e385990> {DAV:}supported-report-set: <Element '{DAV:}supported-report-set' at 0x10e387c90> {DAV:}supportedlock: <Element '{DAV:}supportedlock' at 0x10e387890> {http://twistedmatrix.com/xml_namespace/dav/}resource-class: MMRootResource Failed Properties: {DAV:}acl: 401 2) Observe the value of the current-user-principal attribute. In my case, /principals/users/1.9979107/ I'm not sure what that number is called or how it's derived, but it's probably specified in some spec somewhere :) Anyway, onward: 3) Use the 'user number' as the last component of a /calendars/users/ path, as shown here: / > cd /calendars/users/1.9979107 /calendars/users/1.9979107 > ls BBE4AA14-58E6-46F3-B0E7-B86F66E81390/ M2CD-1-1-6981CC60-E068-44C4-AA9B-6F65C8F25764/ inbox/ notification/ Now we see my calendars. You can see the http traffic by issuing the 'logging' command within CalDAVClientLibrary as shown below.
