我已经在CakePHP 4.0中实现了新的身份验证、授权和请求授权中间件。（从认证的用户）到各种页面。当前，所有未授权的请求都被重定向到我的未授权重定向URL - Pages/Permission页面。是否有方法从RequestPolicy/canAccess函数动态更改未授权的重定向URL？
我的RequestPolicy/canAccess函数看起来像这样（已编辑）：

public function canAccess($identity, ServerRequest $request)
{
    $unauthenticatedActions = $request->getAttribute('authentication')->getConfig('unauthenticatedActions');
    if (in_array($request->getParam('action'), $unauthenticatedActions, true)) { 
        return true;
    }
    else if(!empty($identity)){
        //check based on actions and user roles

        $userRole = $identity->role;
        $userStatus = $identity->status;
        $accountType = $identity->accountsubType;
        $action = $request->getParam('action');
        $controller = $request->getParam('controller');

        switch ($controller) {

            case 'Pages':
                return true;
                break;

            case 'Users':
                    if($userRole === 'ADMIN' && $userStatus === 'ACTIVE'){
                        return true;
                    }elseif($action === 'aaa'){
                        if($userRole === 'xxx' && $userStatus === 'ACTIVE'){
                            return true;
                        }
                        elseif($userRole === 'xxx' && $userStatus === 'EXPIRED'){
                            //redirect to custom 'suspended access' page
                            return false;
                        }
                        elseif($userRole === 'yyy' && $accountType === 'c'){
                            //redirect to custom 'restricted access' page 
                            return false;
                        }
                        else{
                            return false;
                        }
                    }
                    ...
                    return false;
            case: "Sales":   
            ...
            default:
                //none of the Controller names matches
                return false; //redirects to the default unauthorized redirect url (pages/permission)
                //here if I return true, I get the MissingControllerException, MissingActionException etc as expected
    }else{
        //force them back to the login page
        $request =  $request
                    ->withParam('controller', 'users')
                    ->withParam('action', 'login');
        return true; 
    }
}
