A Flarum extension. Login to your Flarum forum using LINE

This extension adds LINE as an OAuth provider to FoF OAuth. You must therefore first enable the OAuth extension before enabling this extension.

Setup

In order to enable Login with LINE, you must first register on the Line developer console.

Once registered, create a new channel of the type LINE login, and select web app. Once you've created the channel, make a note of the Channel ID and Channel secret, then navigate to the LINE login tab. Here enter the callback URL for your forum - this will be displayed within the OAuth extension settings in your admin panel and look something like https://forum.example.com/auth/line.

If you wish to retrieve the registered email address from LINE, you must also complete the OpenID Connect Email Permission within the channel setup.

Enter the Channel ID and Channel secret in the admin panel for your forum (This can be found at {YOUR FORUM URL)/admin#/extension/fof-oauth

Installation

Install with composer:

composer require ianm/oauth-line:"*"

Updating

composer update ianm/oauth-line
php flarum cache:clear

    about android login with line
    after line login succes, page not auto reload ...
    .
    because line login redirect page url to auth ...
    it's make window.opener is null
    https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Opener-Policy
    .
    so ... ResponseFactory.php ... authenticationComplete not work
    window.opener.app.authenticationComplete(%s);
    .
    I add cookieStore.addEventListener

    <script>
cookieStore.addEventListener("change", (event) => {
  window.location.reload();
});
</script>

    .
    then edit ResponseFactory.php (cookieStore.set)

    private function makeResponse(array $payload): HtmlResponse
{
    $content = sprintf(
        '
        <script>
        window.close(); 
        cookieStore.set({name: "isLogin",  value: "yes"});
        window.opener.app.authenticationComplete(%s);
        </script>
        ',
        json_encode($payload)
    );
    return new HtmlResponse($content);
}

    .
    change event not support firefox & safari (but they support window.opener)

          my flarum work, you can try on android phone
          https://opencart.cc

            Subarist Because I am changing layout of the login 🤣
            I put the button of line login at the bottom

                Subarist the owner of the oauth line application seems to need a developer role. That is what the error seems to imply.

                    opencart
                    The login function is now working properly, but on mobile devices, it still cannot directly return to flarum. need to go back to the previous page on the LINE authentication screen.
