Yii2 使用RBAC

1.在/basic/config/console.php和/basic/config/web.php里，配置组件，这里只贴出console.php里的代码 ：

<?phpYii::setAlias('@tests', dirname(__DIR__) . '/tests');$params = require(__DIR__ . '/params.php');$db = require(__DIR__ . '/db.php');return [    'id' => 'basic-console',    'basePath' => dirname(__DIR__),    'bootstrap' => ['log', 'gii'],    'controllerNamespace' => 'app\commands',    'modules' => [        'gii' => 'yii\gii\Module',    ],    'components' => [        'cache' => [            'class' => 'yii\caching\FileCache',        ],        'log' => [            'targets' => [                [                    'class' => 'yii\log\FileTarget',                    'levels' => ['error', 'warning'],                ],            ],        ],        'db' => $db,'authManager' => [    				'class' => 'yii\rbac\DbManager',    				'itemTable' => 'web_auth_item',    				'assignmentTable' => 'web_auth_assignment',    				'itemChildTable' => 'web_auth_item_child',        			'ruleTable'=>'web_auth_rule'    		],    ],    'params' => $params,];

如果console.php里没有配置，会报下面错误：

You should configure "authManager" component to use database before executing this migration.

2.打开命令行

3.cd 命令切换到/php/basic目录

4.输入命令：yii migrate –migrationPath=@yii/rbac/migrations/

5.创建Permission：

    public function createPermission($item)    {        $auth = Yii::$app->authManager;        $createPost = $auth->createPermission($item);        $createPost->description = '创建了 ' . $item . ' 许可';        $auth->add($createPost);    }

6.创建Role:

public function createRole($item)    {        $auth = Yii::$app->authManager;        $role = $auth->createRole($item);        $role->description = '创建了 ' . $item . ' 角色';        $auth->add($role);    }

7.Role分配Permission

 static public function createEmpowerment($items)    {        $auth = Yii::$app->authManager;        $parent = $auth->createRole($items['name']);        $child = $auth->createPermission($items['description']);        $auth->addChild($parent, $child);    }

8.角色分配用户：

 static public function assign($item)    {        $auth = Yii::$app->authManager;        $reader = $auth->createRole($item['name']);        $auth->assign($reader, $item['description']);    }

9.验证权限：

 public function beforeAction($action)    {        $action = Yii::$app->controller->action->id;        if(\Yii::$app->user->can($action)){            return true;        }else{            throw new \yii\web\UnauthorizedHttpException('对不起，您现在还没获此操作的权限');        }    }

10.Controller里的权限验证

class SiteController extends Controller{    public function behaviors()    {        return [            'access' => [                'class' => \y

11.在Controller里自定义验证

class SiteController extends Controller{    public function behaviors()    {        return [            'access' => [                'class' => \yii\web\AccessControl::className(),                'only' => ['special-callback'],                'rules' => [                    [                        'actions' => ['special-callback'],                        'allow' => true,                        'matchCallback' => function ($rule, $action) {                            return date('d-m') === '31-10';                        }                    ],

   // ...    // Match callback called! 此页面可以访问只有每个10月31日    public function actionSpecialCallback()    {        return $this->render('happy-halloween');    }

以上就介绍了Yii2 使用RBAC，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
