如何在Magento中处理媒体/目录/产品/缓存的缓存 [英] How to work Cache of media/catalog/product/cache in Magento

问题描述

我想知道如何处理媒体/目录/产品/缓存的缓存我不知道如何制作目录结构。
我的例子是

i want to know how to work the cache of media/catalog/product/cache i don´t know how made the directory structure. My example is

media\catalog\product\cache

  \1\small_image\120x120\9df78dab3d52sd08dse5fw8d27w36e95

      a\
      b\
      d\
      ...

我不明白如何取缓存中的数字1 \\ $
接下来如何取哈希密钥9df78dab3d52sd08dse5fw8d27w36e95
而且很多次代替higthxweith（目录）取numberx（目录）
我需要知道所有因为我想制作一个外部CDN并解放来调整我机器中的图像大小。
Thx

i don´t understand how to take the number 1 in cache\ next how to take the hash key 9df78dab3d52sd08dse5fw8d27w36e95 and many times in stead of higthxweith(directory) take numberx(directory) I need to know all because i want to made a external CDN and liberate to resize images in my machine. Thx

推荐答案

如果您想了解更多有关该哈希键的信息，我相信它是在Mage_Catalog_Model_Product_Image类中创建的，在setBaseFile函数的底部，它基本上获取图像的属性，将它们一起内爆并创建一个哈希。

If you wish to know more about that hash key, I believe it is created in the Mage_Catalog_Model_Product_Image class, at the bottom of the setBaseFile function, it basically takes properties of the image, implodes them together and creates a hash.

    // add misk params as a hash
    $miscParams = array(
            ($this->_keepAspectRatio  ? '' : 'non') . 'proportional',
            ($this->_keepFrame        ? '' : 'no')  . 'frame',
            ($this->_keepTransparency ? '' : 'no')  . 'transparency',
            ($this->_constrainOnly ? 'do' : 'not')  . 'constrainonly',
            $this->_rgbToString($this->_backgroundColor),
            'angle' . $this->_angle,
            'quality' . $this->_quality
    );

    // if has watermark add watermark params to hash
    if ($this->getWatermarkFile()) {
        $miscParams[] = $this->getWatermarkFile();
        $miscParams[] = $this->getWatermarkImageOpacity();
        $miscParams[] = $this->getWatermarkPosition();
        $miscParams[] = $this->getWatermarkWidth();
        $miscParams[] = $this->getWatermarkHeigth();
    }

如果您需要自己生成哈希，可以使用相同的步骤。显然，HASH'ing是一个单向过程，因此不可能获取值并找出图像属性。

If you need to generate the hash yourself you can use the same steps. Obviously HASH'ing is a one way process, so it is impossible to take the value and find out the image properties.
