Laravel Auth RedirectTo will be ignored

Question

i use the default LoginController from Laravel 5.4 Auth. I just modified the redirectTo property to /

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    use AuthenticatesUsers;
    protected $redirectTo = '/';

    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }
}

Now i logged in as a user. After login the redirect to / works fine. So now i goto /login again and now the trait RedirectsUsers redirect's me to /home.

I think the problem is in the trait on this line:

return property_exists($this, 'redirectTo') ? $this->redirectTo : '/home';

But i didn't understand why. In the LoginController the redirectTo will be set to /.

I don't want to override the RedirectsUsers trait in the vendor directory.

How i can fix the issue?

Answer 1

When user is logging in, redirection is done by using the

/**
 * Where to redirect users after login.
 *
 * @var string
 */
protected $redirectTo = '/';

from app/Http/Controllers/Auth/LoginController.php

---

When user is already logged in and visits the /login page, redirection (to /home) is defined in this middleware

app/Http/Middleware/RedirectIfAuthenticated.php source

if (Auth::guard($guard)->check()) {
    return redirect('/home');
}

guest middleware is defined in app/Http/Kernel.php source

Edited answer to respond to the comment

guest middleware is added to app/Http/Controllers/Auth/LoginController.php source

public function __construct()
{
    $this->middleware('guest')->except('logout');
}
