{/*** Authenticates a user.* The example implementation makes sure if the username and password* are both demo.* In practical applications, this should be changed to authenticate* against some persistent user identity storage (e.g. database).* return boolean whether authentication succeeds.*/public function authenticate(){$usernamestrtolower($this-username);$userUser::model()-find(LOWER(username)?,array($username));if($usernull)$this-errorCodeself::ERROR_USERNAME_INVALID;else if($user-password!$this-password)$this-errorCodeself::ERROR_PASSWORD_INVALID;else{$this-username$user-username;$this-setState(roles, $user-level1?admin:commen_user); //添加用户角色$this-errorCodeself::ERROR_NONE;}return $this-errorCodeself::ERROR_NONE;}}上面这句$this-setState(roles,$user-level1?admin:commen_user)非常重要这里表示添加了一个用户的角色3.重写CWebUser,放在components文件夹下(WebUser.php)class WebUser extends CWebUser
{/*** Overrides a Yii method that is used for roles in controllers (acce***ules).** param string $operation Name of the operation required (here, a role).* param mixed $params (opt) Parameters for this operation, usually the object to access.* return bool Permission granted?*/public function checkAccess($operation, $paramsarray()){if (empty($this-id)) {// Not identified no rightsreturn false;}$role $this-getState(roles);if ($role admin) { //管理员return true; // admin role has access to everything}// allow access if the operation request is the current users rolereturn ($operation $role);}
}4.控制器里修改public function filters(){return array(accessControl, // perform access control for CRUD operationspostOnly delete, // we only allow deletion via POST request);}/*** Specifies the access control rules.* This method is used by the accessControl filter.* return array access control rules*/public function acce***ules(){return array(array(allow, // allow all users to perform index and view actionsactionsarray(index,view,login,passwordupdate),usersarray(*),),array(allow, // allow authenticated user to perform create and update actionsactionsarray(create,update,getuser,delete),rolesarray(admin),//表示只有角色为admin的用户才能访问),array(deny, // deny all usersusersarray(*),),);}5.修改配置文件main.phpuserarray(// enable cookie-based authenticationclassWebUser,allowAutoLogintrue,loginUrl array(/user/login),),6.视图中如何用array(namestatus, typehtml, valueCustomer::showStatus($data-status, $data-id),visible Yii::app()-user-checkAccess(admin)),array(nameemployee_id, typehtml, valueCustomer::isDivided($data-employee_id, $data-id),visible Yii::app()-user-checkAccess(admin)),原理当用户登录的时候获取用户的level字段并添加相应的角色若是1则该用户为admin否则就是common_user.然后重写CWebUser中的checkAccess方法如果是admin则有权操作相应的权限。最后在控制器里rules里定义规则有一个roles属性我们给它设置为admin表示只有角色为admin的才能进行相关的action操作。 转载于:https://blog.51cto.com/php2013/1363163
