Bundle 的 Symfony 4 自定义配置 yaml 文件

Symfony 4 Custom config yaml file for Bundle

我正在尝试将一个包转换为 symfony 4,并且需要将我古老的 parameters.yml 更新为现代的 symfony 4 生活方式。 Basicall 捆绑包本身 - 在多个应用程序之间共享 - 应该在 /config/packages/.

下有一个可配置文件

但是我收到这个错误:

(1/1) InvalidArgumentException

There is no extension able to load the configuration for "ptmr" (in /var/www/html/ptmr/pws_ptmrio_dev/PtmrBundle/DependencyInjection/../../config/packages/ptmr.yaml). Looked for namespace "ptmr", found none

/PtmrBundle/DependencyInjection/PtmrExtension.php

<?php
namespace PtmrBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;

class PtmrExtension extends Extension
{

    public function load(array $configs, ContainerBuilder $container)
    {

        $configuration = new Configuration(true);
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new YamlFileLoader(
            $container,
            new FileLocator(__DIR__ . '/../../config/packages')
        );

        $loader->load('ptmr.yaml');

    }


}

/PtmrBundle/DependencyInjection/Configuration.php

<?php
namespace PtmrBundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{

    private $debug;

    public function  __construct($debug = true)
    {
        $this->debug = (bool) $debug;
    }

    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder('ptmr');

        $treeBuilder->getRootNode()
            ->children()
            ->arrayNode('twitter')
            ->children()
            ->integerNode('client_id')->end()
            ->scalarNode('client_secret')->end()
            ->end()
            ->end() // twitter
            ->end()
        ;

        return $treeBuilder;
    }
}

/config/packages/ptmr.yaml

ptmr:
  twitter:
    client_id: 123
    client_secret: your_secret

-- 笔记: 捆绑包本身有效。

我在 composer.json 中将此行添加到 psr-4:

    "PtmrBundle\": "PtmrBundle/"

这行到config/routes/annotations.yml

ptmr_bundle:
    resource: ../PtmrBundle/Controller/
    type: annotation

配置这些行/services.yaml

services:
    ...

    PtmrBundle\:
        resource: '../PtmrBundle/*'
        exclude: '../PtmrBundle/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

    ...

    PtmrBundle\Controller\:
        resource: '../PtmrBundle/Controller'
        tags: ['controller.service_arguments']

当然还有PtmrBundle/PtmrBundle.php

<?php

namespace PtmrBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class PtmrBundle extends Bundle
{

}

我正在按照这些说明操作,我确实没有看到任何错误。我错过了什么?交响乐 4.2.

您正试图在 Symfony 发现您的包之前加载您的包的配置。您的包 class 必须先加载和配置,然后才能解析 ptmr 属性.

下的配置

通常,您的包会加载 __DIR__.'/../Resources/config/services.yaml,其中包含 serviceparameters 定义。在你的包之外,在你的应用程序 config/ 目录中,然后你将在 ptmr 属性.

下加载配置

终于找到答案了。要制作您自己的 config/bundle.yaml 参数文件,只需执行以下操作:

第 1 步: 在您的包中创建一个文件 DependencyInjection/{BundleNameWithoutBundle}Extension.php,例如对于 MyBundle > MyExtension.php

<?php
namespace MyBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;

class MyExtension extends \Symfony\Component\DependencyInjection\Extension\Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $container->setParameter('my', $config);
    }
}

步骤 2:制作一个配置文件,为您的 .yaml 文件提供架构 DependencyInjection/Configuration.php

<?php

namespace MyBundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder('my');

        $treeBuilder->getRootNode()
            ->children()
                ->variableNode('project_name')->end()
            ->end()
        ;

        return $treeBuilder;
    }
}

另见 How to Create Friendly Configuration for a Bundle

第 3 步:在 config/my.yaml

中镜像 Configuration.php
my:
  project_name: "My Name"

现在参数 my 可用(在 MyExtension Class 中设置)。只需在您的控制器中获取它,例如:

class IndexController extends AbstractController
{
    public function indexAction(ParameterBagInterface $parameterBag)
    {
        ...
        dump($parameterBag->get('ptmr'));
        return $this->render('index.html.twig');
    }

}

注意: 大多数 bundle 更进一步并操作 bundle 配置 xml 文件,这超出了像这样的简单问题的范围。关于如何执行此操作的一个简单示例是 KnpPaginatorBundle,对于设置参数来说理解起来并不过分复杂。

个人说明: 在我看来,Symfony 文档过于复杂,应该提供一个简单的示例。你必须了解很多术语,但很难学会,尤其是与其他有据可查的 symfony 章节相比。
