我在 module.php 上定义了一些服务,它们按预期工作,声明为:
public function getServiceConfig()
{
return array(
'factories' => array(
'Marketplace\V1\Rest\Service\ServiceCollection' => function($sm) {
$tableGateway = $sm->get('ServiceCollectionGateway');
$table = new ServiceCollection($tableGateway);
return $table;
},
'ServiceCollectionGateway' => function ($sm) {
$dbAdapter = $sm->get('PdoAdapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new ServiceEntity());
return new TableGateway('service', $dbAdapter, null, $resultSetPrototype);
},
'Marketplace\V1\Rest\User\UserCollection' => function($sm) {
$tableGateway = $sm->get('UserCollectionGateway');
$table = new UserCollection($tableGateway);
return $table;
},
'UserCollectionGateway' => function ($sm) {
$dbAdapter = $sm->get('PdoAdapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new UserEntity());
return new TableGateway('user', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
我使用它们将我的数据库表映射到一个对象。从我项目的主要课程中,我可以毫无问题地访问它们。看一下我的项目文件树:
例如,userResource.php 扩展了 abstractResource 并且此函数有效:
public function fetch($id)
{
$result = $this->getUserCollection()->findOne(['id'=>$id]);
return $result;
}
在 ResourceAbstract 里面我有:
<?php
namespace Marketplace\V1\Abstracts;
use ZF\Rest\AbstractResourceListener;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class ResourceAbstract extends AbstractResourceListener implements ServiceLocatorAwareInterface {
protected $serviceLocator;
public function getServiceCollection() {
$sm = $this->getServiceLocator();
return $sm->get('Marketplace\V1\Rest\Service\ServiceCollection');
}
public function getUserCollection() {
$sm = $this->getServiceLocator();
return $sm->get('Marketplace\V1\Rest\User\UserCollection');
}
public function setServiceLocator(ServiceLocatorInterface $serviceLocator) {
$this->serviceLocator = $serviceLocator;
}
public function getServiceLocator() {
return $this->serviceLocator;
}
}
正如 Zf2 文档所建议的那样,我需要实现 ServiceLocatorAwareInterface 才能使用 serviceManager。到目前为止,一切都很好。然后我决定添加一个新类,调用 Auth。
这个类与 abstractResource 没有太大区别,它在 loginController 中调用如下:
<?php
namespace Marketplace\V1\Rpc\Login;
use Zend\Mvc\Controller\AbstractActionController;
use Marketplace\V1\Functions\Auth;
class LoginController extends AbstractActionController
{
public function loginAction()
{
$auth = new Auth();
$data = $this->params()->fromPost();
var_dump($auth->checkPassword($data['email'], $data['password']));
die;
}
}
这是授权:
<?php
namespace Marketplace\V1\Functions;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class Auth implements ServiceLocatorAwareInterface {
protected $serviceLocator;
public function setServiceLocator(ServiceLocatorInterface $serviceLocator) {
$this->serviceLocator = $serviceLocator;
}
public function getServiceLocator() {
return $this->serviceLocator;
}
public function checkPassword($email, $rawPassword) {
$user = $this->getServiceLocator()->get('Marketplace\V1\Rest\User\UserCollection')->findByEmail($email);
if($user)
return false;
$result = $this->genPassword($rawPassword, $user->salt);
if($result['password'] === $user->password)
return true;
else
return false;
}
public function genPassword($rawPassword, $salt = null) {
if(!$salt)
$salt = mcrypt_create_iv(22, MCRYPT_DEV_URANDOM);
$options = [
'cost' => 11,
'salt' => $salt,
];
return ['password' => password_hash($rawPassword, PASSWORD_BCRYPT, $options), 'salt' => bin2hex($salt)];
}
}
如您所见,它遵循与 abtractResource 相同的路径,但是,在这种情况下,当我执行 loginController 时,会出现错误:
Fatal error</b>: Call to a member function get() on null in C:\WT-NMP\WWW\MarketPlaceApi\module\Marketplace\src\Marketplace\V1\Functions\Auth.php on line 25
这指的是这一行:$user = $this->getServiceLocator()->get('Marketplace\V1\Rest\User\UserCollection')->findByEmail($email);
这意味着 getServiceLocator 是空的。为什么我不能让 serviceLocator 在 Auth 类上工作,但我可以在 abstractResource 中工作?
