Question

我需要将Laravel应用程序中的默认用户模型更改为Admin模型。我遵循了change Authentication model in Laravel 5.3

中给出的教程

管理员模型必须进行身份验证，注册和重置密码。这是我到目前为止所做的。

完成php artisan make:auth之后，我创建了Admin.php模型

namespace Modules\Admin\Entities;

use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class Admin extends Authenticatable
{
    use Notifiable;
    protected $fillable = ['name','email','password'];
    protected $hidden = [
        'password', 'remember_token',
    ];
}

这是config/auth.php

return [

    /*
    |--------------------------------------------------------------------------
    | Authentication Defaults
    |--------------------------------------------------------------------------
    |
    | This option controls the default authentication "guard" and password
    | reset options for your application. You may change these defaults
    | as required, but they're a perfect start for most applications.
    |
    */

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

    /*
    |--------------------------------------------------------------------------
    | Authentication Guards
    |--------------------------------------------------------------------------
    |
    | Next, you may define every authentication guard for your application.
    | Of course, a great default configuration has been defined for you
    | here which uses session storage and the Eloquent user provider.
    |
    | All authentication drivers have a user provider. This defines how the
    | users are actually retrieved out of your database or other storage
    | mechanisms used by this application to persist your user's data.
    |
    | Supported: "session", "token"
    |
    */

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

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

    /*
    |--------------------------------------------------------------------------
    | User Providers
    |--------------------------------------------------------------------------
    |
    | All authentication drivers have a user provider. This defines how the
    | users are actually retrieved out of your database or other storage
    | mechanisms used by this application to persist your user's data.
    |
    | If you have multiple user tables or models you may configure multiple
    | sources which represent each model / table. These sources may then
    | be assigned to any extra authentication guards you have defined.
    |
    | Supported: "database", "eloquent"
    |
    */

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => \Modules\Admin\Entities\Admin::class,
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],

    /*
    |--------------------------------------------------------------------------
    | Resetting Passwords
    |--------------------------------------------------------------------------
    |
    | You may specify multiple password reset configurations if you have more
    | than one user table or model in the application and you want to have
    | separate password reset settings based on the specific user types.
    |
    | The expire time is the number of minutes that the reset token should be
    | considered valid. This security feature keeps tokens short-lived so
    | they have less time to be guessed. You may change this as needed.
    |
    */

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

];

这是RegisterController.php

namespace App\Http\Controllers\Auth;

use Modules\Admin\Entities\Admin;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:admins'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     */
    protected function create(array $data)
    {
        return Admin::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
    }
}

此代码在admins表中创建一个用户，但是当我尝试登录时，它将引发以下错误：

传递给Illuminate \ Auth \ SessionGuard :: __ construct（）的参数2必须是Illuminate \ Contracts \ Auth \ UserProvider的实例，给定为null，在... \ vendor \ laravel \ framework \ src \ Illuminate \ Auth中调用第125行的\ AuthManager.php

我不明白为什么会发生此错误。

Answer 1

更改config/auth.php上的代码：

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

收件人：

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

Answer 2

所有身份验证驱动程序都有一个用户提供程序。

这定义了实际上是如何从数据库或此应用程序用来持久存储用户数据的其他存储机制中检索用户的。

按如下所示更改您的 config/auth.php 文件：

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