php - 如何在cakephp 1.3中使用独立类？

我有一个用php编写的独立类，用于一些非常基本的ldap/ad函数。我想在cakephp的项目中使用这个类。
在cakephp 1.2中，我可以作为一个供应商添加这个类，但是cakephp1.3似乎删除了对供应商的支持。那么我该如何调用这个类中的一些函数呢？
（我想保持类本身不变，而不是把它变成一个插件，因为这似乎是不必要的）
谢谢！
代码如下：

**<?php
class UsersController extends AppController {

var $name = 'Users';

    //commented out because it breaks the script
    //App::import('Lib', 'ldap');


function index() {
    $this->User->recursive = 0;
    $this->set('users', $this->paginate());
}

    function login() {

        if (!empty($this->data)) {
                if ($ldap->auth($this->data['User']['user'],$this->data['User']['password'])) {
                        $this->Session->setFlash(__('The user has been saved', true));
                        $this->Session->write('user', $this->data['User']['user']);
                        $this->redirect(array('action' => 'index'));
                } else {
                        $this->Session->setFlash(__('Login Failed', true));
                }
        }
    }

    function logout() {
        $this->Session->delete('user');
        $this->redirect($this->referer());

    }

function view($id = null) {
    if (!$id) {
        $this->Session->setFlash(__('Invalid user', true));
        $this->redirect(array('action' => 'index'));
    }
    $this->set('user', $this->User->read(null, $id));
}

function add() {
    if (!empty($this->data)) {
        $this->User->create();
        if ($this->User->save($this->data)) {
            $this->Session->setFlash(__('The user has been saved', true));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The user could not be saved. Please, try again.', true));
        }
    }
    $projects = $this->User->Project->find('list');
    $this->set(compact('projects'));
}

function edit($id = null) {
    if (!$id && empty($this->data)) {
        $this->Session->setFlash(__('Invalid user', true));
        $this->redirect(array('action' => 'index'));
    }
    if (!empty($this->data)) {
        if ($this->User->save($this->data)) {
            $this->Session->setFlash(__('The user has been saved', true));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The user could not be saved. Please, try again.', true));
        }
    }
    if (empty($this->data)) {
        $this->data = $this->User->read(null, $id);
    }
    $projects = $this->User->Project->find('list');
    $this->set(compact('projects'));
}

function delete($id = null) {
    if (!$id) {
        $this->Session->setFlash(__('Invalid id for user', true));
        $this->redirect(array('action'=>'index'));
    }
    if ($this->User->delete($id)) {
        $this->Session->setFlash(__('User deleted', true));
        $this->redirect(array('action'=>'index'));
    }
    $this->Session->setFlash(__('User was not deleted', true));
    $this->redirect(array('action' => 'index'));
}
}

最佳答案

蛋糕1.3仍然完全支持供应商文件的想法。此外，它们now also support "libraries"，不是第三方类的附加类。只需将文件弹出到/vendors或/libs目录，然后使用App::import加载文件。
