Laravel Socialite funktioniert nicht?

Question

Ich habe ein Problem mit Laravel Persönlichkeit des öffentlichen Lebens mit, hier ist der Code:

class SocialAuthController extends Controller 
{ 
    public function redirect($provider) { 
     return Socialite::driver($provider)->redirect();  
    } 
    public function callback(SocialAccountService $service, $provider) { 
     $user = $service->createOrGetUser(Socialite::driver($provider)); 
     auth()->login($user, true); 
     return redirect()->to('/'); 
    } 
} 

SocialAccountService:

public function createOrGetUser(Provider $provider) 
{ 
    $providerUser = $provider->user(); 
    $providerName = class_basename($provider); 
    $account = SocialAccount::whereProvider($providerName) 
     ->whereProviderUserId($providerUser->getId()) 
     ->first(); 
    if ($account) { 
     return $account->user; 
    }else{ 
     $account = new SocialAccount([ 
      'provider_user_id' => $providerUser->getId(), 
      'provider' => $providerName 
     ]); 
     $user = User::whereEmail($providerUser->getEmail())->first(); 
     if (!$user) { 
      $user = User::create([ 
       'email' => $providerUser->getEmail(), 
       'name' => $providerUser->getName(), 
       'avatar' => $providerUser->getAvatar(), 
      ]); 
     } 
     $account->user()->associate($user); 
     $account->save(); 
     return $user; 
    } 
} 

Jetzt das Problem, das ich bekommen habe ist:

FatalThrowableError Type error: Argument 1 passed to Illuminate\Auth\SessionGuard::login() must implement interface Illuminate\Contracts\Auth\Authenticatable, null given, called in /var/www/liveandnow/vendor/laravel/framework/src/Illuminate/Auth/AuthManager.php on line 294

Könnte jemand erklären, Was mache ich falsch? Weil ich alle Probleme nicht sehen hier mit meinem Code

Answer 1

In auth()->login() haben Sie eine Instanz von App\User Modell zu schaffen, aber statt dass Sie vorbei null Wert.

Hier ist der Code, den Sie für (getestet) suchen:

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

public function handleProviderCallback($provider) 
{ 
     $socialMediaUser = Socialite::driver($provider)->user(); 

     $user = $this->findOrCreateUser($socialMediaUser); 

     auth()->login($user); 

     return redirect()->route('home'); 
} 

public function findOrCreateUser($socialMediaUser) 
{ 
    $user = User::where('social_provider_id', $socialMediaUser->getId())->first(); 

    if(is_null($user)) { 
     $user = User::create([ 
      'social_provider_id' => $socialMediaUser->getId(), 
      'name' => $socialMediaUser->getName(), 
      'email' => $socialMediaUser->getEmail(), 
      'avatar' => $socialMediaUser->getAvatar() 
     ]); 
    } 

    return $user; 
}

Hinweis:

Twitter nicht die E-Mail-Adresse des Nutzers angeben, damit dies nicht für Twitter funktioniert:

$user = User::whereEmail($providerUser->getEmail())->first();
