Symfony2:在Twig模板中使用LiipImagineBundle与KnpGaufretteBundle和Amaz

Question

我无法让LiipImagineBundle识别流路径。它不加载图像并应用指定的过滤器集，而是采用流路径并将其视为正常的web路径。

这是我能够从各种来源拼凑出来的配置。我找不到任何确切的解决这个问题的方法。就LiipImagineBundle而言，这些设置似乎根本没有取得任何效果。没有抛出任何错误或警告，日志中也没有任何内容。它完全忽略了我的配置。

Twig:

{{ 'gaufrette://amazon_s3/file.jpg'|imagine_filter('event_small') }}

我几周前就这么做了，但我没有将s3用于缓存。您的问题似乎与图像路径有关。在树枝上试试这个：

{{ 'file.jpg'|imagine_filter('event_small') }}

由于数据加载程序知道您使用的流，缓存解析程序知道文件所在的URL，因此您只需要传递文件名。

另一个与您的配置不同的地方是，我的配置在gaufrite路径上有一个领先的/：

liip_imagine:
  loaders:
    stream.amazon_s3:
      stream:
        wrapper:      gaufrette://amazon_s3/

希望能有所帮助。
