笔记 - Laravel-MultiAuthGuard 多重身份组

目的

使 Laravel 除了原本 User 资料表外的资料表也可以当作纪录登入资讯使用。

一、 建立资料表

使用指令建立资料表：

php artisan make:migration create_admins_table

资料表内容如下：

public function up(){Schema::create('admins', function (Blueprint $table) {$table->id();$table->string('name');$table->string('username')->unique();$table->string('password');$table->rememberToken();$table->timestamps();});}

二、建立 Model

使用指令建立 Model：

php artisan make:model Admin

Model 内引入 Illuminate\Foundation\Auth\User 后将 extends 改为 Authenticatable，并设置 $guard，完整内容如下：

<?phpnamespace App\Models;use Illuminate\Database\Eloquent\Factories\HasFactory;use Illuminate\Database\Eloquent\Model;use Illuminate\Foundation\Auth\User as Authenticatable;class Admin extends Authenticatable{    use HasFactory;    protected $guard = 'admin';    protected $fillable = [        'name', 'username', 'password',    ];    protected $hidden = [        'password', 'remember_token',    ];}

三、定义 guards

打开 config/auth.php，并新增新的 guard 与 provider：

    'guards' => [        'web' => [            'driver' => 'session',            'provider' => 'users',        ],        'admin' => [            'driver' => 'session',            'provider' => 'admins',        ],    ],        ...            'providers' => [        'users' => [            'driver' => 'eloquent',            'model' => App\Models\User::class,        ],        'admins' => [            'driver' => 'eloquent',            'model' => App\Models\Admin::class,        ],    ],

四、透用 Seeder 新增帐号

使用指令建立 Seeder：

php artisan make:seeder CreateAdmin 

打开 database/seeders/CreateAdmin.php，并加入：

use Illuminate\Support\Facades\DB;use Illuminate\Support\Facades\Hash;...public function run(){DB::table('admins')->insert(['name' => 'admin','username' => 'admin','password' => Hash::make('123456'),]);}

然后运行上面写的 Seeder：

php artisan db:seed --class=CreateAdmin

五、建立登入

这边以 Livewire 为例：

namespace App\Http\Livewire\Auth;use Livewire\Component;use Illuminate\Support\Facades\Auth;class Login extends Component{    public $username;    public $password;    public $remember = false;    protected $rules = [        'username' => 'required',        'password' => 'required|min:6',    ];    public function login()    {        if (Auth::guard('admin')->attempt($this->validate(), $this->remember)) {            // 登入成功            return redirect('/posts');        }    }    public function render()    {        return view('livewire.auth.login')            ->layout('layouts.base');    }}

六、限制路由

开启 routes/web.php，并把要登入才能看得页面套上 middleware：

Route::middleware(['auth:admin', 'auth.session'])->group(function () {    Route::get('/posts', App\Http\Livewire\Post\ShowPostList::class);});
