Yii Framework ACF of accessController Simple Privilege Control Operation Example

This article illustrates the simple permission control operation of the Yii framework ACF (accessController). Share it for your reference, as follows:

use yii\filters\AccessControl;
class SiteController extends Controller
{
  public function behaviors()
  {
    return [
      'access' =>[
        'class' => AccessControl::className(),
        'rules' => [
          [
            'allow' => true,
            'actions' => ['index', 'view'],
            'roles' => ['?'],
          ],
          [
            'allow' => true,
            'actions' => ['view','index','create','update'],
            'roles' => ['@'],
          ],
 　　　　　　　　　　　　 [
  　　　　　　　　　　　　 　　 'actions' => ['special-callback'],
  　　　　　　　　　　　　 　　 //'only' => ['special-callback'],
  　　　　　　　　　　　　 　　 'allow' => true,
  　　　　　　　　　　　　 　　 'matchCallback'=>function($rule,$action){
   　　　　　　　　　　　　 　　 　　 return date('Y-m-d') === '2017-02-14';// Only 2017 Year 2 Month 14 Number can only be accessed 
  　　　　　　　　　　　　 　　 },
  　　　　　　　　　　　　 　　 'denyCallback'=>function($rule,$action){ // Rules against access 
  　　　　　　　　　　　　 　　 },
  　　　　　　　　　　　　 　　 'ips'=>[],// Permissible ip
  　　　　　　　　　　　　 　　 'verbs'=>['GET','POST','DELETE'],// Mode of request 
 　　　　　　　　　　　　 ],
        ],
      ],
    ];
  }
  // ...
}

Access rules are set by the following context parameters:

actions: Sets which action matches this rule.

roles: Sets which role matches this rule.

*: Any user, including anonymous and authenticated users.
? Anonymous user.
@: Authenticated users.

ips: Sets which client IP matches this rule.

verbs: Sets which request type (for example, GET, POST) matches this rule.

matchCallback: Specifies an PHP callback to determine that the rule is applied.

denyCallback: The PHP callback is invoked when the rule prohibits access.

public function actionSpecialCallback()
{
  return $this->render('happy-halloween');
}

The above code can be used to control the relevant permissions of visitors and logged-in users of the blog system
