- 设置权限规则表:可放在module模块配置文件里面
public function init() {
//操作权限表,必须存在以下字段:
//itemname角色名/ID,
//type授权项目类型/1(任务)或者2(角色),
//bizrule权限/逻辑运算表达式为false是有权限操作,
//data数据/YII暂无利用
Yii::app()->authManager->itemTable = 'AuthItem';
//会员组-权限对应表,必须存在以下字段:
//child子角色/ID,
//parent父角色/ID,此表可循环执行,可多级继承
Yii::app()->authManager->itemChildTable = 'uthItemChild';
//会员-会员组对应表,会员组可直接为操作名称,必须存在以下字段:
//itemname角色名/ID,
//userid用户名/ID,
//bizrule权限/逻辑运算表达式为false是有权限操作,
//data数据/YII暂无利用
Yii::app()->authManager->assignmentTable = 'zd_mem_glog';
}
- 实现规则,所在控制器继承基类SBaseController,原来为Controller
class ProductController extends SBaseController
{
........
}
class SBaseController extends Controller
{
........
}
- SBaseController继承基类Controller,前填加beforeAction,实现权限验证。
protected function beforeAction($action) {
//载入模块分隔符
$del = Helper::findModule('srbac')->delimeter;
//取得前模块名称
$mod = $this->module !== null ? $this->module->id . $del : "";
$contrArr = explode("/", $this->id);
$contrArr[sizeof($contrArr) - 1] = ucfirst($contrArr[sizeof($contrArr) - 1]);
$controller = implode(".", $contrArr);
$controller = str_replace("/", ".", $this->id);
// 生成静态页面 模块+分隔符+控制器(首字母大写)+方法(首字母大写)例: model-ControllerAction
if(sizeof($contrArr)==1){
$controller = ucfirst($controller);
}
$access = $mod . $controller . ucfirst($this->action->id);
//验证访问页面地址是否在总是允许列表里面,是返回有权限
if (in_array($access, $this->allowedAccess())) {
return true;
}
//验证SRBAC有无安装,没在安装,返回的权限访问
if (!Yii::app()->getModule('srbac')->isInstalled()) {
return true;
}
//验证SRBAC有无开启,没在开启,返回的权限访问
if (Yii::app()->getModule('srbac')->debug) {
return true;
}
// 权限验证
if (!Yii::app()->user->checkAccess($access) || Yii::app()->user->isGuest) {
$this->onUnauthorizedAccess();
} else {
return true;
}
}
- CDbAuthManager读取当前用户角色
public function getAuthAssignments($userId)
{
$rows=$this->db->createCommand()
->select()
->from($this->assignmentTable)
->where('userid=:userid', array(':userid'=>$userId))
->queryAll();
$assignments=array();
foreach($rows as $row)
{
if(($data=@unserialize($row['data']))===false)
$data=null;
$assignments[$row['itemname']]=new CAuthAssignment($this,$row['itemname'],$row['userid'],$row['bizrule'],$data);
}
return $assignments;
}
- CDbAuthManager读取角色对应权限
public function getAuthItem($name)
{
$row=$this->db->createCommand()
->select()
->from($this->itemTable)
->where('name=:name', array(':name'=>$name))
->queryRow();
if($row!==false)
{
if(($data=@unserialize($row['data']))===false)
$data=null;
return new CAuthItem($this,$row['name'],$row['type'],$row['description'],$row['bizrule'],$data);
}
else
return null;
}
- CDbAuthManager读取权限对应操作
protected function checkAccessRecursive($itemName,$userId,$params,$assignments)
{
if(($item=$this->getAuthItem($itemName))===null)
return false;
Yii::trace('Checking permission "'.$item->getName().'"','system.web.auth.CDbAuthManager');
if(!isset($params['userId']))
$params['userId'] = $userId;
if($this->executeBizRule($item->getBizRule(),$params,$item->getData()))
{
if(in_array($itemName,$this->defaultRoles))
return true;
if(isset($assignments[$itemName]))
{
$assignment=$assignments[$itemName];
if($this->executeBizRule($assignment->getBizRule(),$params,$assignment->getData()))
return true;
}
$parents=$this->db->createCommand()
->select('parent')
->from($this->itemChildTable)
->where('child=:name', array(':name'=>$itemName))
->queryColumn();
foreach($parents as $parent)
{
if($this->checkAccessRecursive($parent,$userId,$params,$assignments))
return true;
}
}
return false;
}
- CAuthManager验证权限
public function executeBizRule($bizRule,$params,$data)
{
return $bizRule==='' || $bizRule===null || ($this->showErrors ? eval($bizRule)!=0 : @eval($bizRule)!=0);
}
- 总是充许访问规则设置
