Yii2的rbac怎么关联某一个具体的action,有人有例子吗?
看到Yii::$app->authManager->createPermission('createPost')就可以创建createPost权限了;
然后再分配给某个用户,该用户就拥有这个权限了。
我认为'createPost'应该仅仅是权限的名字而已,事实上他也许对应一个logout操作(假设)。那么Yii怎么把权限和具体的action关联起来的呢?
是不是要配合AccessColtrol来使用呢?如果是,那要这个permission有什么意义呢?直接给role不就可以了?
求指教。3Q first~

正好做到做鉴权判断这块,我给你解答。
AccessColtrol 这种是一种形式
index、view 两个动作就是能通过AccessColtrol来判断了
<code>public function behaviors() { return [ 'access' => [ 'class' => AccessControl::className(), 'only' => ['index', 'view', 'create', 'update'], 'rules' => [ [ 'actions' => ['index'], //来宾可见 'allow' => true, 'roles' => ['?'], ], [ 'actions' => ['view', 'create', 'update'], //登录用户 'allow' => true, 'roles' => ['@'], ], [ 'actions' => ['create', 'update'], //Post请求 'allow' => true, 'verbs' => ['POST'] ], ], ], ]; } public function actionIndex() { return '来宾可见'; } public function actionView() { echo '登录用户可见:'."\n"; return Yii::$app->user->identity->id; } </code>
使用Rbac,放在各自的方法里
优点是使用灵活,缺点是每次都要写相识的代码
<code>public function actionCreate() { if (Yii::$app->user->can('CreatePost')) { return '可以的'; } else { throw new UnauthorizedHttpException('对不起,您现在还没获此操作的权限。'); } } public function actionUpdate() { if (Yii::$app->user->can('UpdatePost')) { return '可以的'; } else { throw new UnauthorizedHttpException('对不起,您现在还没获此操作的权限。'); } } </code>
使用Rbac,放在beforeAction这个方法里
正好跟上面一点相反,要根据请求的动作来判断哪个权限
<code>public function beforeAction($action) { if (parent::beforeAction($action)) { //print_r($action); // 权限名字传递过去(CreatePost) if (!Yii::$app->user->can('CreatePost')) { throw new UnauthorizedHttpException(Yii::t('yii', '对不起,您现在还没获此操作的权限')); } return true; } else { return false; } } </code>
