我仍在努力从Zend Framework之外的ZF2模块实例化一个服务(在一个空白的.php中)。
我想实现:
通过使用ServiceManager和可能的DI实例化+从ZF外部调用ZF2服务方法。
我现在拥有的内容:(更新日期4/10/2013 )
根据以下评论,我做了更多的研究,特别是:
我选择删除所有DI和ModuleManager的东西并尝试自动加载(现在正常工作)并实例化(不)服务。
1 - 使用Classmap自动加载请求的类并在独立的.PHP文件中实例化servicemanager
// Autoload ZF and ProductImage module via classmap
Zend\Loader\AutoloaderFactory::factory(array(
'Zend\Loader\StandardAutoloader' => array(
'autoregister_zf' => TRUE,
),
'Zend\Loader\ClassMapAutoloader' => array(
'/home/frequency/domains/scrftcdn/public_html/ft/shop/php/zendframework/module/ProductImage/autoload_classmap.php',
)
)
)
// Hard-coded servicemanager configuration (will come from $module->getConfig once this works)
$smc = new \Zend\ServiceManager\Config(
array(
'service_manager' => array(
'factories' => array(
'ProductImage\Model\ProductImage' => 'ProductImage\Factory\ProductImageFactory',
)
),
)
);
// Instantiate the service manager
$sm = new \Zend\ServiceManager\ServiceManager($smc);
//Load the service via the service manager
$service = $sm->get('ProductImage\Model\ProductImage'); // <throws exception
die();
2 - 例外

3 - ProductImage \ autoload_classmap.php
<?php
// Generated by ZF2's ./bin/classmap_generator.php
return array(
'ProductImageTest\Service\ProductImageServiceTest' => __DIR__ . '/test/ProductImageTest/Service/ProductImageServiceTest.php',
'ProductImage\Module' => __DIR__ . '/Module.php',
'ProductImage\Factory\ProductImageFactory' => __DIR__ . '/src/ProductImage/Factory/ProductImageFactory.php',
'ProductImage\Model\ProductImage' => __DIR__ . '/src/ProductImage/Model/ProductImage.php',
);
4 - ProductImage \ Module.php
class Module implements \Zend\ModuleManager\Feature\ConfigProviderInterface
{
/* Invoked by Module Manager */
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
}
5 - ProductImage \ config \ module.config.php
<?php
return array(
'service_manager' => array(
'factories' => array(
'ProductImage\Model\ProductImage' => 'ProductImage\Factory\ProductImageFactory',
),
),
);
我希望这是正确的方法,并且离正确的方向不太远。
答案 0 :(得分:2)
我终于找到了解决方案。 Jurian使用实际应用程序的提示使我走上正轨! :)
1 - /zendframework/config/application.config.php。
一切都是默认的,只需确保添加模块即可。我对“应用程序”模块进行了评论,因为我认为它没有任何用处(截至目前)。我还必须将配置文件的路径从'./module'
更改为__DIR__ . '../module'
,因为它查找的是错误的目录(花了一些时间才找到它)。
<?php
return array(
// ...
'modules' => array(
'ProductImage', /* ProductImage module */
// 'Application',
),
// ...
'module_listener_options' => array(
'module_paths' => array(
__DIR__ . '/../module',
__DIR__ . '/../vendor',
),
2 - 配置
确保模块配置正确,并确保ZF2路径设置正确。就我而言,在RTD上快速启动(http://zf2.readthedocs.org/en/latest/ref/installation.html)。我有ZF2_PATH
例外,并通过WHM更改httpd.conf
。
3 - 详细了解RTD
特别是关于如何引导应用程序:http://zf2.readthedocs.org/en/latest/modules/zend.mvc.intro.html#zend-mvc-intro
经过极少的调试后,我生成了以下代码来访问整齐配置的$ sm实例。
//wherever the ZF2 application skeleton is, include the autoloader
require_once '/home/path/to/the/ZF2/application/directory/init_autoloader.php';
use Zend\Loader\AutoloaderFactory;
use Zend\Mvc\Application;
use Zend\Mvc\Service\ServiceManagerConfig;
use Zend\ServiceManager\ServiceManager;
// setup autoloader
AutoloaderFactory::factory();
// get application stack configuration
$configuration = include '/home/path/to/the/ZF2/application/directory/config/application.config.php';
//var_export($configuration);
// The init() method does something very similar with the previous example.
$app = Application::init($configuration);
$sm = $app->getServiceManager();
$pi = $sm->get('ProductImage\Service\ProductImageService');
var_export($pi);
die();
我不喜欢除了init_autoloader路径之外还需要指定配置的事实。我避免将此实现复制并粘贴到所有地方,我正在考虑将$sm
实例化集成到init_autoloader.php
中,以便不必每次都指定配置文件的路径需要调用ProductImage
服务。
