how to run? about caldav-adapter

[sedenardi]

localhost:5232/user/exampleCal1

(ive changed in json user@co to just user.)

You have to use the full username in the URL you're connecting to. So once the server is running, use this as the server:

/caldav/p/user@co

The caldav portion is defined by the caldavRoot option, so you can segment requests on your server. The /p/ means you're connecting to all the calendars for the principal. This is how iOS and MacOS need to connect to CalDAV servers.

I've updated the README with that information.

[lixaotec]

seems the problem is happening with koa.ts

const rootRegexp = pathToRegexp(path.join(rootRoute, '/:params'));
const calendarRegex: CalRegex = { keys: [] };
calendarRegex.regexp = pathToRegexp(path.join(calendarRoute, '/:principalId/:calendarId/:eventId'), calendarRegex.keys);
const principalRegex: CalRegex = { keys: [] };
principalRegex.regexp = pathToRegexp(path.join(principalRoute, '/:principalId'), principalRegex.keys);

pathToRegexp dont like * ? at routes

[sedenardi]

Can you give an example of the URL you're sending? You have to make sure all your URLs are encoded before being sent to this middleware.

I´m trying to use it with iOS 12.4.6 (iphone 5s).

localhost:5232/user/exampleCal1

(ive changed in json user@co to just user.)

When i run the project, at execution time, node seems not to like the * at pathToRegex parameters. i´m stuck at that point.

Thanks for your reply.

Also Ive noticed an behavior at the first comuniction iOS -> caldav adapter it seems to fail when the first response ask for Auth.
It appears, iOS is not expecting the WWW-Authenticate... as it simply fails

Did a resfresh to your code... after npm i
I get this

[sedenardi]

Have you changed anything in the example/server.js file?

[lixaotec]

nope

[lixaotec]

just build from source again.
my node is v12.16.3
I read this regardin path.join()
"Join all arguments together and normalize the resulting path. Arguments must be strings. In v0.8, non-string arguments were silently ignored. In v0.10 and up, an exception is thrown."
Could be that?

[lixaotec]

Think i got
as I am running in windows
rootRoute gets with path.resolve
C:\caldav

[sedenardi]

Ahh, koa.ts should be using path.join rather than path.resolve, since Windows machines use backslashes.

To confirm this is the issue, can you change line 47 of koa.ts, run npm i, and confirm that works?

[lixaotec]

sure, i´m working on it

[lixaotec]

another issue now:
backslash still got \ , instead of /

\caldav

[lixaotec]

perhaps all path.join is working unexpectly with windows env...

[lixaotec]

im trying use path.posix.join

[lixaotec]

It did solve path issues!!

And now we´re on the other trouble with auth..

[lixaotec]

just removed @ex.co from json , so to avoid any possible encoding issue

[sedenardi]

im trying use path.posix.join

Great. I don't have a windows machine to test on so thanks for bringing this to my attention. I've changed the code to use path.posix instead of just path. I'll push that change shortly.

As for the auth issues, what are the server settings you're using? Server, User Name, Password?

@ex.co being in the username isn't an issue, as it gets URL encoded automatically by clients and decoded automatically by the server.

[lixaotec]

Glad to contribute. And thank for the work you´ve done with this project.

i´m using the default settings. Also had tried @ex.co.. in fact no differences, But auth wont accomplish.

localhost:3001, [email protected], pass

I think this step at auth wont working because ios wont send it at the first step
const creds = basicAuth(ctx);

trying to figure out

[sedenardi]

Are you using the full url http://localhost:3001/caldav/p/[email protected] in the iOS or MacOS settings?

[lixaotec]

iOS .. and yes for the path.
Just tried a bunch of variations.

[sedenardi]

And I assume you've confirmed that your phone can access your computer's localhost? I've run into this issue before and had to use ngrok or a similar service.

[lixaotec]

sure. I ve tried directly .. and with a proxy to capture the packages.
I´m pretty sure its something to do with the fact of ios isnt sending credentials at first, as ssl is disabled. and the workflow is expecting another message.

I am looking into this reference: https://wiki.wocommunity.org/display/~probert/CalDAV+and+CardDAV+handshake

[lixaotec]

or perhaps im missing something with realm (dont know how it works)

[sedenardi]

Ahh yeah you may have to use an HTTPS connection. I'm not sure if that's an iOS restriction or not.

[lixaotec]

hum.. how to set koa to respond that?

[sedenardi]

That's sort of outside the scope of this module, but there are many ways to do it. You can use ngrok to create an https tunnel to your localhost for development purposes, or create a self-signed HTTPS cert for your machine.

[lixaotec]

Just manage to make koa listen at https with a simply self signed cert.

And its all working now!

Thank you very much for the attention!
If you wish i may pr this https piece.

Hope to work with you to improve the tool, and share knowledge with you.

[sedenardi]

No problem.
