when opening a URL that requires authentication, web browser will open the redirect

[igalic]

This seems to be primarily on linux when trying to xdg-open a url that requires authentication before access, xdg-open will use whatever that URL redirects to. e.g.:

that means, that when trying to xdg-open https://cloud.digitalocean.com/settings/api/tokens/new - it will actually open https://cloud.digitalocean.com/login

apparently this isn't an xdg-utils bug: https://bugs.freedesktop.org/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&bug_status=NEEDINFO&bug_status=PLEASETEST&component=xdg-utils&query_format=advanced&short_desc=redirect&short_desc_type=allwordssubstr or at least no one has noticed it so far.

I'm going to be testing this out tomorrow. I'll make sure to post back here with my findings.

[igalic]

i've traced this down to kde-open5, now let's see what that does

---

of course that only calls KRun::runService()

[bryanl]

Would you mind describing your setup, so I can help you diagnose this a bit more. I've verified it works on a fresh Ubuntu 14.04.

[igalic]

This is kubuntu 16.04 with its latest plasma desktop

update: from https://quickgit.kde.org/?p=kio.git&a=blob&h=b9b232dc80e9fa9b47f65203aa72b52280124fc1&hb=19fd3c456037c9cd7f762b174172de085fd53673&f=src%2Fwidgets%2Fkrun.cpp (line 104++)

static QString schemeHandler(const QString &protocol)
{
    // We have up to two sources of data, for protocols not handled by kioslaves (so called "helper") :
    // 1) the exec line of the .protocol file, if there's one
    // 2) the application associated with x-scheme-handler/<protocol> if there's one

    // If both exist, then:
    //  A) if the .protocol file says "launch an application", then the new-style handler-app has priority
    //  B) but if the .protocol file is for a kioslave (e.g. kio_http) then this has priority over
    //     firefox or chromium saying x-scheme-handler/http. Gnome people want to send all HTTP urls
    //     to a webbrowser, but we want mimetype-determination-in-calling-application by default
    //     (the user can configure a BrowserApplication though)

    const KService::Ptr service = KMimeTypeTrader::self()->preferredService(QLatin1String("x-scheme-handler/") + protocol);
    if (service) {
        return service->exec(); // for helper protocols, the handler app has priority over the hardcoded one (see A above)
    }
    Q_ASSERT(KProtocolInfo::isHelperProtocol(protocol));
    return KProtocolInfo::exec(protocol);
}

so kde tries to figure out if the resulting url is an image, or a PDF, or whatever, before trying to open it in Gwenview, or Okular, or giving up and opening it in a browser. This is not so good in our case. It would be nice if we could override that.

@igalic I'm working out a solution to make this work with Kubuntu right now.

oh, wow… i haven't had time in almost a month for github gardening ._. thank you @bryanl :purple_heart:!
