我正在尝试在laravel中创建多个表用户和管理员登录，但出现错误

Question

I made changes in auth file but still, I am getting an error.

Argument 2 passed to Illuminate\\Auth\\SessionGuard::__construct() must be an instance of Illuminate\\Contracts\\Auth\\UserProvider, null given, called in C:\\LMS\\vendor\\laravel\\framework\\src\\Illuminate\\Auth\\AuthManager.php on line 123

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

           'admin1' => [
                         'driver' => 'eloquent',
                        'model' => App\RegisterOperation::class,
                       ],

    'guards' => [

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

         'user' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
 'admin' => [
            'driver' => 'session',
            'provider' => 'admin1',
        ],




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

    ],
       'providers' => [

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


],




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

Answer 1

correct your guard, you have something missing under your providers

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



    'guards' => [

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

         'user' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
 'admin' => [
            'driver' => 'session',
            'provider' => 'admin1',
        ],




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

    ],
       'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],
'admin1' => [
                         'driver' => 'eloquent',
                        'model' => App\RegisterOperation::class,
                       ],

],




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

];
