Auth::user（）返回null在Laravel 6

Question

我设置了一个自定义的警卫和登录控制器
登录很好，但不知怎么的，它没有存储经过身份验证的用户

我读过这个"Auth::user（）在Laravel 5.2中返回null"
并且这个"Auth::user（）返回null"

但我认为我的问题与中间件无关

代码如下：

控制器：

<?php

namespace App\Http\Controllers\GuruAuth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{

    use AuthenticatesUsers;

    protected $redirectTo = RouteServiceProvider::GURU_HOME;

    public function showLoginForm(Request $request)
    {
        return view('auth_guru.login');
    }

    protected function guard()
    {
        return Auth::guard('guru');
    }

    public function username()
    {
        return 'username';
    }

    public function __construct()
    {
        $this->middleware('guest:guru')->except('logout');
    }

型号：

<?php

namespace App;

use Illuminate\Foundation\Auth\User as Akun;

class Guru extends Akun
{
    protected $table = 'guru';

    protected $guard = 'guru';

    protected $fillable = [
        'nip', 'nama', 'id_mapel',
        'username', 'password',
    ];

    public function mapel()
    {
        return $this->belongsTo('App\Mapel', 'id_mapel');
    }
}

config/auth.php：

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],

        'admin' => [
            'driver' => 'session',
            'provider' => 'admin',
        ],

        'guru' => [
            'driver' => 'session',
            'provider' => 'guru',
        ],

        'ortu' => [
            'driver' => 'session',
            'provider' => 'ortu',
        ],
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],

        'admin' => [
            'driver' => 'eloquent',
            'model' => App\Admin::class,
        ],

        'guru' => [
            'driver' => 'eloquent',
            'model' => App\Guru::class,
        ],

        'ortu' => [
            'driver' => 'eloquent',
            'model' => App\Ortu::class,
        ],
    ],

我还尝试将此添加到控制器：

    public function authenticated(Request $request, $user)
    {
        $user = $this->guard()->user();
        Auth::setUser($user);
    }

当我试图从视图访问Auth::user（）时，它返回null。

该视图直接从route/web.php调用：

Route::group(['prefix' => 'guru'], function() {
    Route::get('/login', 'GuruAuth\LoginController@showLoginForm')->name('guru.login');
    Route::post('/login', 'GuruAuth\LoginController@login')->name('guru.login.submit');
    Route::get('/dashboard', function() {
        return view('guru.index');
    })->name('guru.dashboard');
});

Answer 1

因此，我不知道为什么会发生这种情况，在最终放弃之后，我想出了一个（不太干净的）解决方案。
现在，我不再使用多个守卫，而是创建一个从用户表到guru/admin表的关系。

这就是我现在访问它的方式Auth:：user（）-

我知道这不是一个好的解决方案，但这是我能找到的最快的解决方法
