功能：用于實現登錄功能
框架：laravel 5.8

一、添加路由器

Route::group( [ 'middleware'=>[] , 'prefix'=>'admin' , 'namespace'=>'Admin' , 'as'=>'admin.' ] , function(){/********************login********************/Route::get('login','LoginController@index')->name( 'login' );//登錄界面/********************登錄后的組************************/Route::group( [ 'middleware'=>[ 'admin.auth' ] ] , function(){Route::get('/','IndexController@index');//后臺首頁});});

二、制作驗證類

<?phpnamespace App\Http\Middleware;use Closure;class AdminAuth {/*** Handle an incoming request.** @param \Illuminate\Http\Request $request* @param \Closure $next** @return mixed*/public function handle( $request , Closure $next ){if( !auth( 'admin' )->check() ){return redirect()->route( 'admin.login' );}return $next( $request );}}

注：放入app\http\middleware文件目錄中

三、添加驗證類到app\http\kernel.php文件中
頭部加上use引入
use App\Http\Middleware\AdminAuth;

在函數中加入

protected $routeMiddleware = ['admin.auth'=> AdminAuth::class, ];

四、config\auth.php文件中加上配置

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

五、建立admin模型

<?phpnamespace App\Models;use Illuminate\Database\Eloquent\Model; use Illuminate\Foundation\Auth\User as Authenticatable;class Admin extends Authenticatable {}

表和模型同名 ，必須有三個字段 username password remember_token

六、login控制器中的登錄驗證方法

if(auth( 'admin' )->attempt( [ 'username'=>$request->username , 'password'=>$request->password ] , $request->remember ) ){return $this->success( '登錄成功' ); }return $this->fail( '賬號或密碼不正確' );

七、返回函數

public function success($info,$data = []) {$return = ['data'=>$data,'status' => 'y',];if($info){$return['info'] = $info;}return response()->json($return); }public function fail($info) {$return = ['info' => $info,'status' => 'n',];return response()->json($return); }
