yii权限控制的方法(三种方法)

本文实例讲述了yii权限控制的方法。分享给大家供大家参考，具体如下：

这里摘录以下3种：

1. 通过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('*'),
    ),
  );
}

2. 通过插件（如：right）

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

3. 混合模式:

/**
 * @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();
}

如果有权限的基础上，开放某些动作的权限，可以通过allowedactions:

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

希望本文所述对大家基于yii框架的php程序设计有所帮助。
