PHP 访问控制的实施方案

use RoleBasedControl as RBC; $user = new User(); $user->setUsername('admin'); $role = new Role(); $role->setName('manager'); $permission = new Permission(); $permission->setPermission('manage_users'); $rbac = new RBC(); $rbac->assignUserToRole($user, $role); $rbac->assignPermissionToRole($permission, $role); if ($rbac->hasAccess($user, $permission)) { // 允许访问 } else { // 拒绝访问 }

use AttributeBasedControl as ABC; $user = new User(); $user->setAttribute('age', 25); $user->setAttribute('location', 'USA'); $resource = new Resource(); $resource->setAttribute('sensitivity', 'high'); $policy = new Policy(); $policy->setAttribute('age', '>= 21'); $policy->setAttribute('location', 'USA'); $policy->setPermission('read'); $abc = new ABC(); $abc->addPolicy($policy); if ($abc->hasAccess($user, $resource)) { // 允许访问 } else { // 拒绝访问 }

$user = $_SESSION['user']; if ($user->hasRole('admin')) { // 显示管理仪表板 } else { // 重定向到主页 }
