yii2 Rbac实例（做完以下这些会有些小的报错，相信各位都能解决，大多数都是自己命名空间上的问题）。

首先我自己没有使用自带的user表

如果model层没有AuthItem.php 那就自建一个将下面这些内容写入

<?php

namespace backend\models;

use Yii;

/**
 * This is the model class for table "auth_item".
 *
 * @property string $name
 * @property integer $type
 * @property string $description
 * @property string $rule_name
 * @property resource $data
 * @property integer $created_at
 * @property integer $updated_at
 *
 * @property AuthAssignment[] $authAssignments
 * @property AuthRule $ruleName
 * @property AuthItemChild[] $authItemChildren
 * @property AuthItemChild[] $authItemChildren0
 * @property AuthItem[] $children
 * @property AuthItem[] $parents
 */
class AuthItem extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'auth_item';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['name', 'type'], 'required'],
            [['type', 'created_at', 'updated_at'], 'integer'],
            [['description', 'data'], 'string'],
            [['name', 'rule_name'], 'string', 'max' => 64],
            [['rule_name'], 'exist', 'skipOnError' => true, 'targetClass' => AuthRule::className(), 'targetAttribute' => ['rule_name' => 'name']],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'name' => 'Name',
            'type' => 'Type',
            'description' => 'Description',
            'rule_name' => 'Rule Name',
            'data' => 'Data',
            'created_at' => 'Created At',
            'updated_at' => 'Updated At',
        ];
    }

    /**
     * @return \yii\db\ActiveQuery
     */
    public function getAuthAssignments()
    {
        return $this->hasMany(AuthAssignment::className(), ['item_name' => 'name']);
    }

    /**
     * @return \yii\db\ActiveQuery
     */
    public function getRuleName()
    {
        return $this->hasOne(AuthRule::className(), ['name' => 'rule_name']);
    }

    /**
     * @return \yii\db\ActiveQuery
     */
    public function getAuthItemChildren()
    {
        return $this->hasMany(AuthItemChild::className(), ['parent' => 'name']);    }    /**     * @return \yii\db\ActiveQuery     */    public function getAuthItemChildren0()    {        return $this->hasMany(AuthItemChild::className(), ['child' => 'name']);    }    /**     * @return \yii\db\ActiveQuery     */    public function getChildren()    {        return $this->hasMany(AuthItem::className(), ['name' => 'child'])->viaTable('auth_item_child', ['parent' => 'name']);    }    /**     * @return \yii\db\ActiveQuery     */    public function getParents()    {        return $this->hasMany(AuthItem::className(), ['name' => 'parent'])->viaTable('auth_item_child', ['child' => 'name']);    }}

要想使用yii rbac组件首先需要在我们的配置文件中开启 rbac组件

在common/config/main-local.php 中添加下边的组建

'authManager' => [
    'class' => 'yii\rbac\DbManager',
    'itemTable' => 'auth_item',
    'assignmentTable' => 'auth_assignment',
    'itemChildTable' => 'auth_item_child',
],

接下来创建我们的表

首先创建控制权限的四张表

这四张表的sql在我们的yii的核心文件中具体路径是

vendor/yiisoft/yii2/rbac/migrations/schma-mysql.sql

这是我们操作mysql的sql语句

另外的文件分别操作 sql server oracle postgresql sqlite

然后因为需要个我们的用户分配权限我们还需要使用我们的yii的用户表这个用户表的sql 下边给出

可以参考地址 http://www.yiichina.com/question/285

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) NOT NULL,
`auth_key` varchar(32) NOT NULL,
`password_hash` varchar(255) NOT NULL,
`password_reset_token` varchar(255) DEFAULT NULL,
`email` varchar(255) NOT NULL,
`role` smallint(6) NOT NULL DEFAULT '10',
`status` smallint(6) NOT NULL DEFAULT '10',
`created_at` int(11) NOT NULL,
`updated_at` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

在这里我偷懒了一下没有自己在写一个登录和注册功能而是使用yii自带的登录功能影响不大因为我们在进行权限操作

时，只需要只要是谁有权限就行了，其他信息不需要。如果是在项目中，user表可以自定义

下边开始实现rbac。我们对自己要求高一点，代码都要符合yii的规范。尽量不要使用自己的方法而是用框架封装好的

首先创建一个model层 Rbac.php
<?php
/**
* Created by PhpStorm.
* User: jinlei
* Date: 2017/2/16
* Time: 9:58
*/

namespace frontend\models;

use yii\widgets\ActiveForm;
use yii\helpers\Html;
use yii\base\Model;

class Rbac extends Model
{
public $power;
public $role;
}

然后创建控制器 RbacController.php
<?php
/**
* Created by PhpStorm.
* User: jinlei
* Date: 2017/1/13
* Time: 8:47
*/

namespace backend\controllers;

use backend\models\Rbac;
use yii\web\Controller;
use yii;

class RbacController extends Controller
{

}

下边开始权限的操作

第一步添加权限

首先来一个添加权限的页面

public function actionIndex(){
        $model = new Rbac();
        return $this->render('index',['model'=>$model]);
    }

然后创建 views 层

<?php
/**
* Created by PhpStorm.
* User: jinlei
* Date: 2017/2/16
* Time: 10:06
*/

use yii\helpers\Html;
use yii\widgets\ActiveForm;

$form = ActiveForm::begin([
    'id' => 'login-form',
    'options' => ['class' => 'form-horizontal'],
    'action'=>'?r=rbac/power',
    'method'=>'post',
]) ?>
    <?= $form->field($model, 'power') ?>

<div class="form-group">
        <div class="col-lg-offset-1 col-lg-11">
            <?= Html::submitButton('添加权限', ['class' => 'btn btn-primary']) ?>
        </div>
    </div>
<?php ActiveForm::end() ?>

然后在控制器里把权限入库

public function actionPower()
    {
        $item = \Yii::$app->request->post('Rbac')['power'];
        $auth = Yii::$app->authManager;
        $createPost = $auth->createPermission($item);
        $createPost->description = '创建了 ' . $item . ' 权限';
        $auth->add($createPost);

return $this->redirect('?r=rbac/role');
}

接下来创建角色

首先创建一个添加角色的表单

//创建一个就角色的表单

public function actionRole(){
        $model = new Rbac();
        return $this->render('role',['model'=>$model]);
    }

然后进入view层

<?php
/**
* Created by PhpStorm.
* User: jinlei
* Date: 2017/2/16
* Time: 13:52
*/

use yii\helpers\Html;
use yii\widgets\ActiveForm;

$form = ActiveForm::begin([
    'id' => 'login-form',
    'options' => ['class' => 'form-horizontal'],
    'action'=>'?r=rbac/addrole',
    'method'=>'post',
]) ?>
<?= $form->field($model, 'role') ?>

<div class="form-group">
        <div class="col-lg-offset-1 col-lg-11">
            <?= Html::submitButton('添加角色', ['class' => 'btn btn-primary']) ?>
        </div>
    </div>
<?php ActiveForm::end() ?>

然后将角色入库

/添加角色入库

public function actionAddrole(){
        $item = \Yii::$app->request->post('Rbac')['role'];
        $auth = Yii::$app->authManager;
        $role = $auth->createRole($item);
        $role->description = '创建了 ' . $item . ' 角色';
        $auth->add($role);

return $this->redirect('?r=rbac/rp');
}

然后给角色分配权限

public function actionRp(){
        $model = new Rbac();
        $role = AuthItem::find()->where('type=1')->asArray()->all();
        foreach($role as $value){
            $roles[$value['name']] = $value['name'];
        }
        $power= AuthItem::find()->where('type=2')->asArray()->all();
        foreach($power as $value){
            $powers[$value['name']] = $value['name'];
        }

return $this->render('rp',['model'=>$model,'role'=>$roles,'power'=>$powers]);
}

然后到views层进行分配

<?php
/**
* Created by PhpStorm.
* User: jinlei
* Date: 2017/2/16
* Time: 14:05
*/

use yii\helpers\Html;
use yii\widgets\ActiveForm;

$form = ActiveForm::begin([
    'id' => 'login-form',
    'options' => ['class' => 'form-horizontal'],
    'action'=>'?r=rbac/empowerment',
    'method'=>'post',
]) ?>
<?= $form->field($model, 'role')->checkboxList($role) ?>
<?= $form->field($model, 'power')->checkboxList($power) ?>

<div class="col-lg-offset-1 col-lg-11">
            <?= Html::submitButton('提交', ['class' => 'btn btn-primary']) ?>
        </div>
    </div>
<?php ActiveForm::end() ?>

然后入库

public function actionEmpowerment(){
        $auth = Yii::$app->authManager;
        $data = \Yii::$app->request->post('Rbac');
        $role = $data['role'];
        $power = $data['power'];

foreach($role as $value){
foreach($power as $v){
$parent = $auth->createRole($value);

$child = $auth->createPermission($v);
               //var_dump($child);
               $auth->addChild($parent, $child);
           }
       }
return $this->redirect('?r=rbac/fenpei');
    }

然后给用户分配角色

public function actionFenpei(){
        $model = new Rbac();
        $role = AuthItem::find()->where('type=1')->asArray()->all();//注意AuthItem，如果你用的自己新建的登录表需要将它改为你自己的表名
        foreach($role as $value){
            $roles[$value['name']] = $value['name'];
        }
        $user= User::find()->asArray()->all();
        foreach($user as $value){
            $users[$value['id']] = $value['username'];
        }
        return $this->render('fenpei',['model'=>$model,'role'=>$roles,'user'=>$users]);
    }

分配角色的views层

<?php
/**
* Created by PhpStorm.
* User: jinlei
* Date: 2017/2/16
* Time: 14:05
*/

use yii\helpers\Html;
use yii\widgets\ActiveForm;

$form = ActiveForm::begin([
    'id' => 'login-form',
    'options' => ['class' => 'form-horizontal'],
    'action'=>'?r=rbac/ur',
    'method'=>'post',
]) ?>
<?= $form->field($model, 'user')->checkboxList($user) ?>
<?= $form->field($model, 'role')->checkboxList($role) ?>

<div class="form-group">
        <div class="col-lg-offset-1 col-lg-11">
            <?= Html::submitButton('提交', ['class' => 'btn btn-primary']) ?>
        </div>
    </div>
<?php ActiveForm::end() ?>

将给用户分配的角色入库

public function actionUr(){
        $auth = Yii::$app->authManager;
        $data = \Yii::$app->request->post('Rbac');
        $role = $data['role'];
        $power = $data['user'];

foreach($role as $value) {
            foreach ($power as $v) {
                $reader = $auth->createRole($value);
                $auth->assign($reader, $v);
            }
        }
    }

然后在你想要使用权限控制的控制器添加上下面的方法

 //检测权限
    public function beforeAction($action)
    {
        $user_id= Yii::$app->session['id'];
        $action=$_REQUEST['r'];
//这句是查询你所拥有的角色所拥有的权限
        $sql="select child from auth_assignment as a inner join auth_item_child as b on a.item_name=b.parent where user_id=$user_id";
        $ar=\yii::$app->db->createCommand($sql)->queryAll();
        //将所查出来的权限  转化为一维数组（因为下边的条件需要一个一维数组做比对）
        $arr = array_column($ar, 'child');
//        print_r($arr);die;
//条件里所用的函数不懂得可以百度就知道什么意思了
        if(in_array($action, $arr)){
            return true;
        }else{
            throw new \yii\web\UnauthorizedHttpException('对不起，您现在还没获此操作的权限');
        }
    }

这样你就可以实现依据actionID的权限控制了
