如何在 Magento Api 的产品列表方法结果中包含产品图片 [英] How to include product images in Magento Api's product list method result

问题描述

我想尽量减少连接到基于 Magento 的商店以展示产品的移动应用程序的 Api 调用次数.现在我们必须为每个产品调用 catalog_product_attribute_media.list 方法来获取图片 Urls，这确实减慢了应用程序的速度.

I want to minimize the number of Api calls for a mobile application which connects to Magento based shop to display products. right now we have to call catalog_product_attribute_media.list method for each product in order to get image Urls and it really slows down the app.

我在此答案中发现可以通过编辑某些脚本来扩展 Api 调用的结果.我尝试使用相同的方法通过编辑 app/code/core/Mage/Catalog/Model/Category/Api.php 第 440 行将图像包含在产品列表中:

I found out in this answer that it is possible to extend the result of an Api Call by editing certain scripts. I tried to use the same approach to include images in product list by editing app/code/core/Mage/Catalog/Model/Category/Api.php line 440:

$storeId = $this->_getStoreId($store);
$collection = $category->setStoreId($storeId)->getProductCollection()
->addAttributeToSelect('brand')
->addAttributeToSelect('media_gallery_images');
($storeId == 0)? $collection->addOrder('position', 'asc') : $collection->setOrder('position', 'asc');;

$result = array();

foreach ($collection as $product) {
    $result[] = array(
        'product_id' => $product->getId(),
        'type'       => $product->getTypeId(),
        'set'        => $product->getAttributeSetId(),
        'sku'        => $product->getSku(),
        'position'   => $product->getCatIndexPosition(),
        'brand'      => $product->getData('brand'),
    'media'      => $product->getMediaGalleryImages()
    );
}

return $result;

我还编辑了 html/app/code/core/Mage/Catalog/etc/wsdl.xml 以包含新的媒体"属性行:255

I also edited html/app/code/core/Mage/Catalog/etc/wsdl.xml to include the new 'media' property line: 255

    <complexType name="catalogAssignedProduct">
        <all>
            <element name="product_id" type="xsd:int"/>
            <element name="type" type="xsd:string"/>
            <element name="set" type="xsd:int"/>
            <element name="sku" type="xsd:string"/>
            <element name="position" type="xsd:int"/>
            <element name="brand" type="xsd:string"/>
            <element name="media" type="typens:catalogProductImageEntityArray"/>
        </all>
    </complexType>

但是当我调用 catalog_category.assignedProducts 时，它总是为 'media' 属性返回 null，我想知道为什么这不起作用?是xml类型还是别的什么?

but when I call the catalog_category.assignedProducts it always returns null for the 'media' property, I wonder why this doesn't work? is it the xml type or something else?

推荐答案

感谢 这个答案 我想出了如何在结果中包含图像:这是我修改 app/code/core/Mage/Catalog/Model/Category/Api.php 中的assignedProducts 方法的方法，它起作用了:

Thanks to this answer I figured out how to include images in the results: here's how I modified the assignedProducts method in app/code/core/Mage/Catalog/Model/Category/Api.php and it worked:

public function assignedProducts($categoryId, $store = null)
{
    $category = $this->_initCategory($categoryId);

    $storeId = $this->_getStoreId($store);
    $collection = $category->setStoreId($storeId)->getProductCollection()
    ->addAttributeToSelect(array('brand','image','price','description','short_description','name'));
    ($storeId == 0)? $collection->addOrder('position', 'asc') : $collection->setOrder('position', 'asc');

    $result = array();
    $type = 'image';
    foreach ($collection as $product) {
        $result[] = array(
            'product_id' => $product->getId(),
            'type'       => $product->getTypeId(),
            'set'        => $product->getAttributeSetId(),
            'sku'        => $product->getSku(),
            'position'   => $product->getCatIndexPosition(),
            'brand'      => $product->getData('brand'),
            'price'      => $product->getData('price'),
            'name'      => $product->getData('name'),
            'description'      => $product->getData('description'),
            'short_description'      => $product->getData('short_description'),
            'image_url'  => $product-> getImageUrl() 
        );
    }

    return $result;
}
