問題：參數 #1 ($user) 必須是 Illuminate\Contracts\Auth\Authenticatable 類型，null 給定，調用

Question

我是 Laravel 的初學者。 我正在使用 jetstream 進行身份驗證。 當我嘗試注冊到數據庫時，它會保存到數據庫但會出現此錯誤。 那么我該如何解決這個問題

我的 HomeController 是：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Auth;

class HomeController extends Controller
{
    protected $user;


    public function __construct(){
        $this->middleware(function ($request, $next) {
            $this->user= Auth::user();

            return $next($request);
        });
    }

    public function main(){
        return view('welcome');
    }

    public function home(){
        return view('design2.index');
    }

    public function logout(Request $request) {
        Auth::logout();
        return redirect('/');
      }

    public function register(){
        return view('design2.registerpage');
    }

    public function login_page(){
        return view('design2.loginpage');
    }

    public function profile(){
        return view('profile');
    }

}

我的用戶 model 是：

<?php

namespace App\Models;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Fortify\TwoFactorAuthenticatable;
use Laravel\Jetstream\HasProfilePhoto;
use Laravel\Sanctum\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens;
    use HasFactory;
    use HasProfilePhoto;
    use Notifiable;
    use TwoFactorAuthenticatable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
        'two_factor_recovery_codes',
        'two_factor_secret',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    /**
     * The accessors to append to the model's array form.
     *
     * @var array
     */
    protected $appends = [
        'profile_photo_url',
    ];
}

我的 CreateNewUser 是：

<?php

namespace App\Actions\Fortify;

use App\Models\User;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Laravel\Fortify\Contracts\CreatesNewUsers;
use Laravel\Jetstream\Jetstream;

class CreateNewUser implements CreatesNewUsers
{
    use PasswordValidationRules;

    /**
     * Validate and create a newly registered user.
     *
     * @param  array  $input
     * @return \App\Models\User
     */
    public function create(array $input)
    {
        Validator::make($input, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => $this->passwordRules(),
            
            
        ])->validate();

        $save = User::create([
            'name' => $input['name'],
            'email' => $input['email'],
            'password' => Hash::make($input['password']),
        ]);
 

    }
}

錯誤是：

Illuminate\Auth\SessionGuard::login(): 參數 #1 ($user) 必須是 Illuminate\Contracts\Auth\Authenticatable 類型，null 給定，在 /Applications/XAMPP/xamppfiles/htdocs/muzik/vendor/laravel/ 中調用fortify/src/Http/Controllers/RegisteredUserController.php 在第 56 行

Answer 1

嘗試返回創建的用戶，而不是將其保存在變量$save中。

    public function create(array $input)
    {
        Validator::make($input, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => $this->passwordRules(),                     
        ])->validate();

        return User::create([
            'name' => $input['name'],
            'email' => $input['email'],
            'password' => Hash::make($input['password']),
        ]);
    }
