PluginManager :: Get无法获取或为FileQueryPlugin创建实例

Question

我正在使用Zend Framework 2.3.9。我正在尝试使用依赖项注入从视图助手来调用插件" filequeryplugin"。

我尝试将"插件"更改为模块中的" controler_plugins"，但我得到了相同错误消息的变体。

这是Module.config.php

'view_helpers' => array(
    'invokables'=> array(
        'MenuBuildLink' => 'qatoolsViewHelperMenuBuildLink',
    ),
    'factories' => array(
        'FileQuery' => function ($container, $requestedName) {
            return new qatoolsViewHelperFileQuery($container->getServiceLocator()->get(ZendMvcControllerPluginManager::class)->get('FileQueryPlugin'));
        },
    ),
),
'plugins' => array(
    'invokables'=> array(
        'FileQueryPlugin' => 'qatoolsPluginsFileQueryPlugin'
    ),
),

这是filequeryplugin.php

<?php
namespace qatoolsPlugins;
namespace ZendView;
use ZendI18nTranslatorTranslatorAwareInterface;
use ZendServiceManagerAbstractPluginManager;
use ZendServiceManagerConfigInterface;
class FileQueryPlugin extends AbstractPluginManager {
    public function fileQuery($filename) {
        $fileQuery = $this->getServiceLocator->get('qatoolsModelGroupFilesTable');
        $modified = $fileQuery->getModifiedBy($filename);
        return $modified;
    }
    public function validatePlugin($plugin) {
    }
}
?>

我正在看到以下错误消息。

Answer 1

您的命名中有不一致。

您的工厂功能正在调用以下：

return new qatoolsViewHelperFileQuery(...);

当您的className为 FileQueryPlugin。

您应该重命名课程或致电new qatoolsViewHelperFileQueryPlugin(...);

更新

您需要在FileQueryPlugin.php文件中删除较低的命名空间声明，并且上部应与您在工厂中调用的命名空间相对应(qatoolsViewHelperFileQueryPlugin：

namespace qatoolsPlugins; // <--- update this so it corresponds
namespace ZendView;  // <--- remove this one

您还应确保文件所在的文件夹对应于路径qatoolsViewHelperFileQuery，因此文件夹树看起来应该像这样：

- qatools
   - View 
     - Helper
       - FileQueryPlugin.php
