Auth::login() not working properly laravel 5.7

Question

I'm trying to setup 'Login with facebook' using laravel socialite. When I try to login, it gets a successful callback from the facebook, I'm storing the data fetched into the database and try to redirect to home page. While doing so, I am redirected back to the login page and never reaching the homepage.

While debugging the error I found that my Auth::login($user) is not working properly.

Here is the code-

AuthController.php

use App\Http\Controllers\Controller;
use Laravel\Socialite\Two\InvalidStateException;
use Auth;
use Socialite;
use App\User;

public function redirectToProvider($provider)
{
    return Socialite::driver($provider)->redirect();
}

public function handleProviderCallback($provider)
{
    $user = Socialite::driver($provider)->user();
    // dd($user);
    $authUser = $this->findOrCreateUser($user, $provider);
    // dd($authUser);
    if(Auth::login($authUser, true)){            // here is the error
      return redirect($this->redirectTo);
    }
    else{
      return 'Login not done';                 //this prints out to the screen
    }
}

public function findOrCreateUser($user, $provider)
 {
     $authUser = User::where('id', $user->id)->first();
     if ($authUser) {
         return $authUser;
     }
     return User::create([
         'name'     => $user->name,
         'email'    => $user->email,
         'avatar'    => $user->avatar,
         'password'    => bcrypt('password'),
         'provider' => $provider,
         'id' => $user->id
     ]);
 }

Do let me know what am I doing wrong.

This is what I'm getting while dd($authUser)

Answer 1

Since you are grabbing user details and saving them to your database you in order to login you need to use attempt and passing the details that you get from $authUser variable, but you need a way to get the password since the attempt convert the password string to the hash in order to login the user

$authUser = $this->findOrCreateUser($user, $provider);
  $credentials = $request->only($authUser->email, 'password');

        if (Auth::attempt($credentials)) {
            // Authentication passed...
            return redirect()->intended('dashboard');
        }

In my end, I just resolved it by making the domain null in my session.php. I dont know if this is the correct answer but I can now redirect to my homepage after logging in with google. Maybe if you deploy this to production you will change the domain thing to the actual url.

/*
    |--------------------------------------------------------------------------
    | Session Cookie Domain
    |--------------------------------------------------------------------------
    |
    | Here you may change the domain of the cookie used to identify a session
    | in your application. This will determine which domains the cookie is
    | available to in your application. A sensible default has been set.
    |
    */

    'domain' => null,

    /*
    |--------------------------------------------------------------------------
    | HTTPS Only Cookies
    |--------------------------------------------------------------------------
    |
    | By setting this option to true, session cookies will only be sent back
    | to the server if the browser has a HTTPS connection. This will keep
    | the cookie from being sent to you if it can not be done securely.
    |
    */

    'secure' => false,

Auth::login() return void. use

Auth::login($authUser, true);

if(Auth::check()){
  return redirect($this->redirectTo);
}
else{
  return 'Login not done';
}

you should use auth()->login($user); function after create user to add user to auth
