php - Auth::user() 在 Laravel 5.8 中返回 null

Question

我在 Laravel 5.8.10 项目中遇到身份验证问题。我没有使用 Laravel 创建的用于身份验证的默认表单。当我在浏览器中访问 URL/仪表板时，通常用户会在登录时被重定向。该应用程序无论如何都允许它。此外，当我使用 Auth::user() 时，它返回 null。

当我键入无效的用户名和密码时，它不会从登录屏幕传递。当我键入无效凭据时，它会重定向到仪表板。通过仪表板 View 访问 URL 的问题也仍然存在。就好像您不需要身份验证就可以访问该路由。

注意:我的 .env 文件中有一个变量 PASSWORD_HASH 用于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 Controller

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

<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 false 时，它​​停止加密密码，而当为 true 时，进行加密。这是有效的。

1. 在没有授权的情况下停止重定向到仪表板使用授权中间件路由

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

2. env 返回字符串，而不是 bool 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
     }
   }
