yii permission control methods (three methods), yii permission control

This article describes the yii permission control method with examples. Share it with everyone for your reference, the details are as follows:

Here are the following 3 excerpts:

1. Through accessControl:

public function filters()
{
  return array(
    'accessControl', // perform access control for CRUD operations
  );
}
/**
 * Specifies the access control rules.
 * This method is used by the 'accessControl' filter.
 * @return array access control rules
 */
public function accessRules()
{
  return array(
    array('allow', // allow authenticated users to access all actions
      'users'=>array('@'),
    ),
    array('deny', // deny all users
      'users'=>array('*'),
    ),
  );
}

Copy after login

2. Through plug-ins (eg: right)

public function filters()
{
  return array(
    'rights',
  );
}

Copy after login

3. Mixing mode:

/**
 * @return array action filters
 */
public function filters()
{
  return array(
    'updateOwn + update', // Apply this filter only for the update action.
    'rights',
  );
}
/**
 * Filter method for checking whether the currently logged in user
 * is the author of the post being accessed.
 */
public function filterUpdateOwn($filterChain)
{
  $post=$this->loadModel();
  // Remove the 'rights' filter if the user is updating an own post
  // and has the permission to do so.
  if(Yii::app()->user->checkAccess('PostUpdateOwn', array('userid'=>$post->author_id)))
    $filterChain->removeAt(1);
  $filterChain->run();
}

Copy after login

If you want to open certain actions based on permissions, you can pass allowedActions:

public function allowedActions()
{
  return 'autocomplate,autocomplate2';
}

Copy after login
