Laravel oauth user redirection after registration - php

Question

all. I'm just trying to implement Single sign-on server using Laravel and passport app.
What I'm trying to achieve: A single sign-on server who listen to the request from the client and provide the authentication based on the requested parameter.
What I've achieved so far: The SSO server who listen to the client request and provide the authentication and redirect back to the client site only if the user already registered on the SSO server.
The problem is coming to the picture when the user is not registered on SSO server and try to register the account In this case Laravel register user and redirect back to the homepage instead client callback URL.
Please let me know if this is achievable in Laravel or someone does something special for it.

Answer 1

It is pretty much achievable, depends on how much effort you want to put towards it.
When the user is registering, you can save the callback URL in the session.
session(['callback' => $callback]);
Upon registration, redirect the user to their callback URL
return redirect()->away(session('callback'));
If you are still using the default Auth/RegisterController provided by laravel, you can change the redirect behavior by defining a custom redirect function
protected function redirectTo()
{
return redirect()->away(session('callback'));
}
Laravel will automatically pick it up.
Don't forget to delete the property
protected $redirectTo = '/home';

Yes you can do this with some customization in default registration functionality, you have to replace some code in RegistrationController as provided below:
app\Http\Controllers\Auth\RegistrationController
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use AuthenticatesUsers, RegistersUsers {
AuthenticatesUsers::redirectPath insteadof RegistersUsers;
AuthenticatesUsers::guard insteadof RegistersUsers;
}
public function register(Request $request)
{
$this->validator($request->all())->validate();
event(new Registered($user = $this->create($request->all())));
if ($this->attemptLogin($request)) {
if ($request->hasSession()) {
$request->session()->put('auth.password_confirmed_at', time());
}
return $this->sendLoginResponse($request);
}
}
