- 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
