Yii2 Use RBAC

: This article mainly introduces the use of RBAC in Yii2. For more information about PHP tutorials, see. 1. in/basic/config/console. php and/basic/config/web. php, configure the component. here only the code in console. php is pasted:

  '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,];

If no configuration is available in console. php, the following error is reported:

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

2. open the command line

3. switch the cd command to the/php/basic directory.

4. enter the command: yii migrate -- migrationPath = @ yii/rbac/migrations/

5. create Permission:

Public function createPermission ($ item) {$ auth = Yii: $ app-> authManager; $ createPost = $ auth-> createPermission ($ item ); $ createPost-> description = 'created '. $ item. 'license '; $ auth-> add ($ createPost );}

6. create a Role:

Public function createRole ($ item) {$ auth = Yii: $ app-> authManager; $ role = $ auth-> createRole ($ item ); $ role-> description = 'created '. $ item. 'role'; $ auth-> add ($ role );}

7. Role allocation 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. assign a role to a user:

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

9. verify permissions:

Public function beforeAction ($ action) {$ action = Yii: $ app-> controller-> action-> id; if (\ Yii :: $ app-> user-> can ($ action) {return true;} else {throw new \ yii \ web \ UnauthorizedHttpException ('sorry, you have not yet obtained the permission for this operation ');}}

10. permission verification in Controller

class SiteController extends Controller{    public function behaviors()    {        return [            'access' => [                'class' => \yii\web\AccessControl::className(),                'only' => ['login', 'logout', 'signup'],                'rules' => [                    [                        'actions' => ['login', 'signup'],                        'allow' => true,                        'roles' => ['?'],                    ],                    [                        'actions' => ['logout'],                        'allow' => true,                        'roles' => ['@'],                    ],                ],            ],        ];    }    // ...

11. Custom Verification in Controller

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! This page can only be accessed for every October 31 public function actionSpecialCallback () {return $ this-> render ('happy-Halloween ');}

The above introduces the use of RBAC in Yii2, including some content, and hope to be helpful to friends who are interested in PHP tutorials.
