PHP and WordPress Single Sign On (SSO) with optional JWT Addon

maicol07

Hari for the WP repo yes, I'm working on it. I'll see if I can generate an API key from the extension, but I don't promise anything about that. For the moment, run a composer install --no-dev in plugin folder to solve the issue with the WP plugin

tharuka Try to deactivate all the extensions except SSO on Flarum and see if the issue persists

tharuka

maicol07 I installed a fresh copy of flarum only with the plugin and used your examples provided but same thing happens

maicol07

tharuka that's strange... if you see the URL of the button is correct, the redirect starts when Flarum is loading. Can you try to dump $request->getUri() in LoginMiddleware.php (extension)?

C:\wamp64\www\sso\forum\vendor\maicol07\flarum-ext-sso\src\Middleware\LoginMiddleware.php:25:
object(Laminas\Diactoros\Uri)[752]

'https' => int 443
private 'scheme' => string 'http' (length=4)

private 'port' => null
private 'path' => string '/' (length=1)
private 'query' => string '' (length=0)

This is the data I get from that

tharuka ok, so here is the issue. I'll look at that. Keep an eye on the tracker to get updated when I'll solve it: https://tracker.maicol07.it/issue/FSSOE-19

maicol07 Thank you very much 😃

tharuka

maicol07 Hey. I hardcoded the forum URL in LoginMiddleware and now it works. I know that's not a good solution but thought that you should be informed. Again thanks for this great plugin.

maicol07

tharuka So, you wrote the full URL instead of getting it from the config file?
Thank you for letting me know it

tharuka

maicol07 instead of $request->getUri() in RedirectResponse I used my forum URL. Then it worked. I think the problem is that $request->getUri() passes the root URL to the RedirectResponse funtion in LoginMiddleware.

maicol07

tharuka the only issue in this way is that you'll always be redirect to Flarum root and not to the page you requested

tharuka

maicol07 No. Since I used this with Codeigniter 4. I can use redirect function to redirect to the URL I want and It works. I don't know about $flarum->redirect() method which provide in the library.

maicol07

tharuka I didn't mean that. The $flarum->redirect() method only redirects the user to Flarum root. What I say is within the extension. The middleware runs on every request to Flarum. So if the user clicks a link to a discussion in your Flarum (i.e. from google) then the login middleware runs. If user is signed in in your auth system then it will be logged in and page is refresh (Redirect to the same page). Writing the forum url overrides this refresh and redirects to Flarum root

tharuka

maicol07 Oh I see. That is a problem. Hope you will find a solution. Again thank you for your hard work.

Is there any way I could use Google OAuth with this plugin? I tried setting up Google Social Login with a WP plugin but it doesn't seem to login into Flarum.

maicol07

Sanyu you must use a plugin for WP for this to work that uses the standard WP auth flow (basically, it must call the authenticate filter). Ask the plugin developer or choose another plugin

Sanyu

maicol07 Ok thanks for the info!

Hi @maicol07
Sorry to bother you a lot.
My folder structure is like this

www
->sso
-->forum
------>public
------>vendor
-->vendor
-->index.php
-->flarum.php
-->delete.php
->.......

index.php for login in inside the sso folder and forum folder is also at the same place
localhost/sso to load login page and localhost/sso/forum/public is the forum url.

I used these parameters as follows
FLARUM_HOST=http://localhost/sso/forum/public
API_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
ROOT_DOMAIN=localhost

Can you point out anything wrong with this configuration? I used the given example login forms with your php library. Still I can't figure out this problem. It always redirects me to localhost intsed of forum public url which I redirected using header("Location: http://localhost/sso/forum/public"); after logging in

maicol07

tharuka do you get logged into Flarum if you return to it manually?

tharuka

maicol07 Yes. After getting redirected to localhost I can go to localhost/sso/forum/public folder and I'm logged in.

maicol07

tharuka are you able to check if it gets redirected before the login middleware by echoing something?

tharuka

maicol07 When I echo Done at LoginMiddleware I get an output like below

Done
( ! ) Fatal error: Uncaught Laminas\HttpHandlerRunner\Exception\EmitterException: Output has been emitted previously; cannot emit response in C:\wamp64\www\sso\forum\vendor\laminas\laminas-httphandlerrunner\src\Exception\EmitterException.php on line 24

this line 24 is the echo line which I put. It is getting redirected at the LoginMiddleware. This only happens when a user logged in for the first time after logging out.
