Symfony2未加载服务


Symfony2 not loading Service

im试图按照文档书的示例使用Synfony 2创建/加载服务,但遇到了这个问题。目前我有

<?php
//src/AppBundle/Services/AmazonWS.php
namespace AppBundle'Services;
use Aws'S3'S3Client;
class AmazonWS
{
    function __construct($bucket,$key,$secret){}
}

并为我服务。yml:

parameters:
#    parameter_name: value
  amazonws.S3_BUCKET : "synfony"
  amazonws.S3_KEY : "my_key"
  amazonws.S3_SECRET : "my_secret"
services:
#    service_name:
#        class: AppBundle'Directory'ClassName
#        arguments: ["@another_service_name", "plain_value", "%parameter_name%"]
AmazonWS:
  class: AppBundle'Services'AmazonWS
  arguments: ["%amazonws.S3_BUCKET%","%amazonws.S3_KEY%","%amazonws.S3_SECRET%"]

我得到以下错误:

 [Symfony'Component'Config'Exception'FileLoaderLoadException]                                                                                                                                  
  There is no extension able to load the configuration for "AmazonWS" (in /home/sergio/Desktop/hello_symfony_heroku/app/config/services.yml). Looked for namespace "AmazonWS", found "framewor  
  k", "security", "twig", "monolog", "swiftmailer", "assetic", "doctrine", "sensio_framework_extra", "debug", "web_profiler", "sensio_distribution" in /home/sergio/Desktop/hello_symfony_hero  
  ku/app/config/services.yml (which is being imported from "/home/sergio/Desktop/hello_symfony_heroku/app/config/config.yml").                                                                  

  [Symfony'Component'DependencyInjection'Exception'InvalidArgumentException]                                                                                                                    
  There is no extension able to load the configuration for "AmazonWS" (in /home/sergio/Desktop/hello_symfony_heroku/app/config/services.yml). Looked for namespace "AmazonWS", found "framewor  
  k", "security", "twig", "monolog", "swiftmailer", "assetic", "doctrine", "sensio_framework_extra", "debug", "web_profiler", "sensio_distribution" 

我用配置了yml

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: services.yml }

您是否尝试过使用AppBundle中的依赖项注入?

src/AppBundle/DependencyInjection/AppExtension.php:

<?php
namespace AppBundle'DependencyInjection;
use Symfony'Component'DependencyInjection'ContainerBuilder;
use Symfony'Component'Config'FileLocator;
use Symfony'Component'HttpKernel'DependencyInjection'Extension;
use Symfony'Component'DependencyInjection'Loader;
class AppExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);
        $loader = new Loader'YamlFileLoader(
            $container,
            new FileLocator(__DIR__.'/../Resources/config')
        );
        $loader->load('services.yml');
    }
}

然后使用位于src/AppBundle/Resources/config/services.yml中的services.yml(如果它不存在,请创建它(。

缩进:

services:
    AmazonWS:
        class: AppBundle'Services'AmazonWS
        arguments: ["%amazonws.S3_BUCKET%","%amazonws.S3_KEY%","%amazonws.S3_SECRET%"]
