我对中间件RedirectIfAuthenticated有问题

当我在任何控制器中使用此中间件时，未检测到用户连接（用户连接为NULL）。即，我使用多重身份验证。

RedirectIfAuthenticated

class RedirectIfAuthenticated
{
    public function handle($request, Closure $next, $guard = null){
        //dd(Auth::guard($guard)->check()); // when the user is connected the result is null 
        //dd(Auth::user()); // when the user is connect the result is => Argument 2 passed to Illuminate\Auth\SessionGuard::__construct() must be an instance of Illuminate\Contracts\Auth\UserProvider, null given, called in /Users/diegoruiz/Desktop/app/XXX/vendor/laravel/framework/src/Illuminate/Auth/AuthManager.php on line 123


        if($guard == 'admin' && Auth::guard($guard)->check()) {
            return redirect('admin/accueil');
        }else if($guard == 'employer' && Auth::guard($guard)->check()){
            return redirect('/accueil');
        } else {
            return $next($request);
        }
    }
}

LoginController

    class LoginController extends Controller{
       use AuthenticatesUsers;
    ...
    public function __construct(){

    $this->middleware('guest')->except('logout');//It's not working.
    //$this->middleware('guest:admin')->except('logout');//It's not working.

    }
...
    }

config / auth.php

<?php
return [

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
        'admin' => [
            'driver' => 'session',
            'provider' => 'admin',
        ],
        'admin-api' =>[
            'driver' => 'token',
            'provider' => 'admins',

        'employer'=>[

        'employer-api'=>[

    ],

    'providers' => [
       'admins'=> [
            'driver' => 'UtilisateurUserProvider',
            'model' => App\Admin::class,
        ],
        'employers'=>[
            'driver' => 'UtilisateurUserProvider',
            'model'=> App\Employer::class
        ]
        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],



    'passwords' => [
        'users' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],
        'admin' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],
        'employer' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],

    ],

];

UtilisateurUserProvider

<?php

namespace App\Providers;

use Illuminate\Auth\EloquentUserProvider as UserProvider;
use Illuminate\Contracts\Auth\Authenticatable as UserContract;
use Illuminate\Contracts\Support\Arrayable;
use Illuminate\Support\Str;

class UtilisateurUserProvider extends UserProvider{

    public function boot()
    {
        //
    }

    public function register(){
        //
    }

    public function retrieveByCredentials(array $credentials)
    {
        if (empty($credentials) ||
            (count($credentials) === 1 &&
                array_key_exists('mdp', $credentials))) {
            return;
        }

        // First we will add each credential element to the query as a where clause.
        // Then we can execute the query and, if we found a user, return it in a
        // Eloquent User "model" that will be utilized by the Guard instances.
        $query = $this->createModel()->newQuery();

        foreach ($credentials as $key => $value) {
            if (Str::contains($key, 'uti_mdp')) {
                continue;
            }
            if (is_array($value) || $value instanceof Arrayable) {
                $query->whereIn($key, $value);
            } else {
                $query->where($key, $value);
            }
        }

        return $query->first();
    }

    public function validateCredentials(UserContract $user, array $credentials){

        $plain = $credentials['mdp'];
        return $this->hasher->check($plain, $user->getAuthPassword());
    }

}

内核

class Kernel extends HttpKernel
{
    protected $middleware = [
        \App\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,

    protected $middlewareGroups = [
        'web' => [

            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,

        ],

        'api' => [
            'throttle:60,1',
            'bindings',
        ],
    ];

        'entrepriseDatabase' => \App\Http\Middleware\SetEntrepriseDatabase::class,
    ];
}

当我在视图中使用Auth::user()时遇到此错误

Answer 1

如果您的任务是澄清用户并将他们重定向到其他路由，那么我将提供不使用中间件的另一种方式。enter image description here

Answer 2

问题出在 config / auth.php 中，当您调用Auth::user()时，它将在auth.php中看到用户Auth，但是根据您的auth.php，它丢失了： / p>

'providers' => [
   'admins'=> [
        'driver' => 'UtilisateurUserProvider',
        'model' => App\Admin::class,
    ],
    'employers'=>[
        'driver' => 'UtilisateurUserProvider',
        'model'=> App\Employer::class
    ]
    // 'users' => [
    //     'driver' => 'database',
    //     'table' => 'users',
    // ],
],

您必须提供用户，并在用户表中添加另一个包含雇员，管理员等的列角色。您的表关系不正确。
