Hi Panos,

Thanks for looking this up for me.

I've been trying with some variations of this - so far without success!

QC #21444 would also help!

best regards,

Ben

BTW if you want to add a whitelist for ATS in the plist, here are some more details on which keys/values you need and how to add them:

    Hi Ben,

    The "App URL Query Whitelist" field is for specifying a list of custom url
    schemes that the standalone can launch (using the "launch URL
    custom_url_scheme" command) on iOS 9+.

    See bug https://quality.livecode.com/show_bug.cgi?id=18687
    <https://quality.livecode.com/show_bug.cgi?id=18687> for more details.

    Best,

        Aha! Thanks Sean, that was a good tip: I now understand the problem.

        On simulator, my cut-down test app worked fine.

        On device, console shows:

            App Transport Security has blocked a cleartext HTTP (http://)
            resource load since it is insecure. Temporary exceptions can be
            configured via your app's Info.plist file.


        The Oauth2 library requires the redirect URL to be of the form
        `http://127.0.0.1:port` - you pass the port number to the library, it
        assumes the `http://127.0.0.1`.

        The Dropbox app setup allows you to specify an HTTP redirect (but only
        for localhost redirect URLs). So this is all good - except it appears
        that iOS is not so happy! Not sure why an http connection to localhost
        should be insecure, but there you go. (Or indeed why ATS doesn't kick
        in on the simulator?)

        I've posted a report in the QCC (#21442) to extend Oauth2 command to
        in some way allow the redirect URL to be HTTPs.

        In the meantime, I resigned myself to doing a custom info.plist, but
        found something that I'd not spotted before in the iOS Standalone Spp
        Settings: "App URL Query Whitelist" - which I thought might be exactly
        what I needed. Although I couldn't find any documentation for it.

        I still don't know what it does - but it doesn't do this! Does anyone
        know what it does do?

        There is also a checkbox "Disable ATS" - checking this displays a dire
        warning, doubtless correctly; but does indeed provide an easier way to
        solve the problem, at least for development. What it would do to your
        chances of getting an app into the App Store is another question.

        I've also added a report in the QC (#21444) - I thought I'd done this
        before, but maybe I just whinged on the mailing lists - for the
        Standalone Builder to support generic additions to the info.plist
        rather than requiring a completely separate one for anything 
unsupported.

                I feel I've been through this before, but I've not been on it
                for a while, and I'm still (again) stuck.

                Using Oauth2 to connect an app to the Dropbox API works fine
                on desktop.

                On iOS, I get the overlay; with the Dropbox log-in; I sign in,
                and it then shows the message that this app would like access
                to the files in Dropbox, with buttons (from Dropbox) Cancel or
                Allow (and a link "Learn more").

                However, neither the Cancel nor Allow buttons do anything.
                Fortunately there is now an LC 'cancel' button at the bottom
                of the overlay (thanks Monte!
                https://github.com/livecode/livecode/pull/6315
                <https://github.com/livecode/livecode/pull/6315>).

                But something's not happening which should (I assume) happen
                when the user touches "Allow". (There is a tiny bit of visible
                feedback.)

                I know on a previous occasion I solved my issue with
                inclusions, but I don't think that's the problem this time. I
                have (manual inclusions) the Browser widget, the JSON and
                Oauth2 libraries, and the internet library. The call to Oauth2
                is wrapped in a try block, and I'm not seeing a catch (can't
                be sure that I would, but when I use the new emergency cancel,
                my script just reports "Not authorised" where if I drop the
                Oauth2 library, I get a dialog reporting the catch).

                What am I missing? Is anyone else able to succesfully connect
                to Dropbox using the Oauth2 library on LC 9.0.0, iOS 9.3 (or
                any similar environments)?

                TIA,

                Ben
