Auth::user() 在 Laravel 5.8 中返回 null

Question

我在我的 Laravel 5.8.10 项目中遇到了身份验证问题。我没有使用 Laravel 为身份验证创建的默认表单。当我在浏览器中访问 URL/仪表板时，通常用户会在登录时获得重定向重定向。无论如何，该应用程序都允许它。此外，当我使用 Auth::user() 时，它返回 null。

当我输入无效的用户名和密码时，它不会从登录屏幕传递。当我输入无效凭据时，它会重定向到仪表板。通过仪表板视图访问 URL 的问题也继续存在。就好像你不需要身份验证来访问路由一样。

注意：我的 .env 文件中有一个变量 PASSWORD_HASH 来启用或禁用密码加密。

用户模型

namespace App\Entities;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Authenticatable
{
    use Notifiable;
    use SoftDeletes;

    protected $table = "users";
    public $timestamps = true;

    protected $fillable = [
        'cpf', 'name', 'phone', 'birth', 'gender', 'notes', 'email', 'password', 'status', 'permission'
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];

    public function groups()
    {
        return $this->belongsToMany(Group::Class, 'user_groups');
    }

    public function setPasswordAttribute($value)
    {
        $this->attributes['password'] = env('PASSWORD_HASH') ? bcrypt($value) : $value;
    }
}

config/auth.php

return [
    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],
    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
    ],
    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\Entities\User::class,
        ],
    ],
    'passwords' => [
        'users' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],
    ],
];

仪表板控制器

public function auth(Request $request)
{
    $data = [
        'email' => $request->get('username'),
        'password' => $request->get('password')
    ];
    try {
        if (env('PASSWORD_HASH')) {
            Auth::attempt($data, false);
        } else {
            $user = $this->repository->findWhere(['email' => $request->get('username')])->first();

            if (!$user)
                throw new Exception("O e-mail informado é inválido. PEEEEN!");
            if ($user->password != $request->get('password'))
                throw new Exception("A senha informada é inválida. PEEEEN!");
            Auth::login($user);
        }
        return redirect()->route('user.dashboard');
    } catch (Exception $e) {
        return $e->getMessage();
    }
}

路线

Route::get('/login', ['uses' => 'Controller@fazerlogin']);
Route::post('/login', ['as' => 'user.login', 'uses' => 'DashboardController@auth']);
Route::get('/dashboard', ['as' => 'user.dashboard', 'uses' => 'DashboardController@index']);

查看登录信息

<section id="conteudo-view" class="login">
    <h1>Investindo</h1>
    <h3>O nosso gerenciador de investimento</h3>
    {!! Form::open(['route' => 'user.login', 'method' => 'post']) !!}
    <p>Acesse o sistema</p>
    <label>
        {!! Form::text('username', null, ['class' => 'input', 'placeholder' => "Usuário"]) !!}
    </label>
    <label>
        {!! Form::password('password', ['placeholder' => 'Senha']) !!}
    </label>
    {!! Form::submit('Entrar') !!}
    {!! Form::close() !!}
</section>

.env

PASSWORD_HASH=false

这个想法是，当注册用户时它为假时，它会停止加密密码，当它为真时，进行加密。这是有效的。

1. 在没有身份验证的情况下停止重定向到仪表板使用身份验证中间件路由

   Route::middleware(['auth'])->group(function () {    
       Route::get('/dashboard', ['as' => 'user.dashboard', 'uses' => 'DashboardController@index']);    
   });
   

2. env 返回字符串，不是布尔值，所以使用env('PASSWORD_HASH') == 'true' 检查密码哈希是否启用

3. 使用loginUsingId()手动登录。

   if(env('PASSWORD_HASH') == 'true') {
       Auth::attempt($data, false);
   } else {
     $user = User::where('email', $request->username)->where('password', $request->password)->first();
   
     if(!$user){
       throw new Exception("O e-mail informado é inválido. PEEEEN!");
     } else {
       Auth::loginUsingId($user->id);
       //redirect
     }
   }
