Bagaimana cara mendapatkan gambar dan URL produk di Magento 2?

Ini adalah pengamat saya:

public function execute(\Magento\Framework\Event\Observer $observer)
{
    $orderIds = $observer->getEvent()->getOrderIds();
    $order = $this->_orderRepositoryInterface->get($orderIds[0]);
    $items =$order->getAllVisibleItems();
    $productQuantity = array();
    $productPrice = array();
    $productName = array();
    $productIds = array();
    foreach($items as $item) {
        $productIds[]= $item->getProductId();
        $productName[]= $item->getSku(); 
        $productPrice[] = $item->getPrice();
        $productQuantity[]= floor($item->getQtyOrdered());
    }
}

Bagaimana saya bisa mendapatkan gambar produk dan URL produk dari item?

Cara ini mungkin bukan cara terbaik untuk mendapatkan gambar produk.

Suntikkan \Magento\Catalog\Api\ProductRepositoryInterfaceFactorydi konstruktor kami.

protected $_productRepositoryFactory;

public function __construct(
        \Magento\Catalog\Api\ProductRepositoryInterfaceFactory $productRepositoryFactory
) {

    $this->_productRepositoryFactory = $productRepositoryFactory;
}

Kita bisa mendapatkan gambar:

$product = $this->_productRepositoryFactory->create()->getById($item->getProductId());
$product->getData('image');
$product->getData('thumbnail');
$product->getData('small_image');

Jika Anda ingin URL tampilan depan / cache dari suatu gambar untuk tampilan toko tertentu (seperti yang saya lakukan) ini berfungsi untuk saya:

/**
 * @var \Magento\Store\Model\App\Emulation
 */
protected $appEmulation;

/**
 * @var \Magento\Store\Model\StoreManagerInterface
 */
protected $storeManager;

/**
 * @var \Magento\Catalog\Api\ProductRepositoryInterfaceFactory
 */
protected $productRepositoryFactory;

/**
 * @var \Magento\Catalog\Helper\ImageFactory
 */
protected $imageHelperFactory;

/**
 * @param \Magento\Store\Model\StoreManagerInterface $storeManager
 * @param \Magento\Store\Model\App\Emulation $appEmulation
 * @param \Magento\Catalog\Api\ProductRepositoryInterfaceFactory $productRepositoryFactory
 * @param \Magento\Catalog\Helper\ImageFactory $helperFactory
 */
public function __construct(
    \Magento\Store\Model\StoreManagerInterface $storeManager,
    \Magento\Store\Model\App\Emulation $appEmulation,
    \Magento\Catalog\Api\ProductRepositoryInterfaceFactory $productRepositoryFactory,
    \Magento\Catalog\Helper\ImageFactory $imageHelperFactory
)
{
    $this->storeManager = $storeManager;
    $this->appEmulation = $appEmulation;
    $this->productRepositoryFactory = $productRepositoryFactory;
    $this->imageHelperFactory = $imageHelperFactory;
}

Lalu, di mana pun Anda perlu mendapatkan URL frontend gambar:

$sku = "my-sku";
// get the store ID from somewhere (maybe a specific store?)
$storeId = $this->storeManager->getStore()->getId();
// emulate the frontend environment
$this->appEmulation->startEnvironmentEmulation($storeId, \Magento\Framework\App\Area::AREA_FRONTEND, true);
// load the product however you want
$product = $this->productRepositoryFactory->create()->get($sku);
// now the image helper will get the correct URL with the frontend environment emulated
$imageUrl = $this->imageHelperFactory->create()
  ->init($product, 'product_thumbnail_image')->getUrl();
// end emulation
$this->appEmulation->stopEnvironmentEmulation();

Anda dapat memilih jenis gambar lain selain product_thumbnail_image: lihat magento/theme-frontend-luma/etc/view.xmldaftar gambar produk yang tersedia, atau buat gambar Anda sendiri dalam view.xmlfile.

Jika Anda perlu mengembalikan URL produk, URL akan terlihat seperti ini:

//todo get product object $product 

$objectManager =\Magento\Framework\App\ObjectManager::getInstance();
$helperImport = $objectManager->get('\Magento\Catalog\Helper\Image');

$imageUrl = $helperImport->init($product, 'product_page_image_small')
                ->setImageFile($product->getSmallImage()) // image,small_image,thumbnail
                ->resize(380)
                ->getUrl();
echo $imageUrl;

Itulah yang saya lakukan. cukup efisien dan bersih:

1) Pertama, Anda perlu menyuntikkan kelas-kelas berikut:

protected $_storeManager;
protected $_appEmulation;
protected $_blockFactory;

public function __construct(
    ...
    \Magento\Store\Model\StoreManagerInterface $storeManager,
    \Magento\Framework\View\Element\BlockFactory $blockFactory,
    \Magento\Store\Model\App\Emulation $appEmulation)
{
    $this->_storeManager = $storeManager;
    $this->_blockFactory = $blockFactory;
    $this->_appEmulation = $appEmulation;
}

2) Kemudian, buat metode getImageUrl dengan kode di bawah ini:

protected function getImageUrl($product, string $imageType = '')
{
    $storeId = $this->_storeManager->getStore()->getId();

    $this->_appEmulation->startEnvironmentEmulation($storeId, \Magento\Framework\App\Area::AREA_FRONTEND, true);

    $imageBlock =  $this->_blockFactory->createBlock('Magento\Catalog\Block\Product\ListProduct');
    $productImage = $imageBlock->getImage($product, $imageType);
    $imageUrl = $productImage->getImageUrl();

    $this->_appEmulation->stopEnvironmentEmulation();

    return $imageUrl;
}

Catatan: Kode "appEmulation" hanya diperlukan ketika Anda melakukan panggilan ini dari admin atau untuk API . Jika tidak, Anda akan mendapatkan kesalahan di bawah ini (atau serupa):

Unable to resolve the source file for 'webapi_rest/_view/en_AU/Magento_Catalog/images/product/placeholder/.jpg'

3) Panggil getImageUrl lewat objek produk dan jenis gambar yang Anda inginkan (berdasarkan file view.xml Anda )

...
$smallImage = $this->getImageUrl($productObject, 'product_page_image_small');
...

Untuk mendapatkan url gambar khusus, saya menggunakan kode ini. Jadi jika gambar tidak keluar itu akan memuat gambar tema default.

$product = $block->getProduct();

$productImageAttr = $product->getCustomAttribute('product_banner_image');

if ($productImageAttr && $productImageAttr->getValue() != 'no_selection') {

    $productImage = $this->helper('Magento\Catalog\Helper\Image')
    ->init($product, 'product_banner_image')
    ->setImageFile($productImageAttr->getValue());

    $imageUrl = $productImage->getUrl();

} else {

    $imageUrl = $this->getViewFileUrl('images/cat-img1.jpg'); // Theme/web/images

}
