Cree programáticamente un producto simple en magento 2

Me gustaría crear un producto simple mediante programación en magento 2. ¿Hay alguna forma de crear?

Aquí, encontré las soluciones para crear un producto mediante programación a través de un archivo php personalizado, es decir test.php.

<?php
use Magento\Framework\App\Bootstrap;
include('app/bootstrap.php');
$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();

$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');


$_product = $objectManager->create('Magento\Catalog\Model\Product');
$_product->setName('Test Product');
$_product->setTypeId('simple');
$_product->setAttributeSetId(4);
$_product->setSku('test-SKU');
$_product->setWebsiteIds(array(1));
$_product->setVisibility(4);
$_product->setPrice(array(1));
$_product->setImage('/testimg/test.jpg');
$_product->setSmallImage('/testimg/test.jpg');
$_product->setThumbnail('/testimg/test.jpg');
$_product->setStockData(array(
        'use_config_manage_stock' => 0, //'Use config settings' checkbox
        'manage_stock' => 1, //manage stock
        'min_sale_qty' => 1, //Minimum Qty Allowed in Shopping Cart
        'max_sale_qty' => 2, //Maximum Qty Allowed in Shopping Cart
        'is_in_stock' => 1, //Stock Availability
        'qty' => 100 //qty
        )
    );

$_product->save();
?>

En primer lugar, en su constructor querrá incluir tres clases para la inyección de dependencias: Magento\Catalog\Api\Data\ProductInterfaceFactory, Magento\Catalog\Api\ProductRepositoryInterfacey Magento\CatalogInventory\Api\StockRegistryInterface. El primero se genera, así que no te preocupes demasiado si aparece como no existente en tu IDE.

public function __construct(\Magento\Catalog\Api\Data\ProductInterfaceFactory $productFactory, \Magento\Catalog\Api\ProductRepositoryInterface $productRepository, \Magento\CatalogInventory\Api\StockRegistryInterface $stockRegistry)
{
    $this->productFactory = $productFactory;
    $this->productRepository = $productRepository;
    $this->stockRegistry = $stockRegistry;
}

A partir de ahí, donde desee crear el producto, deberá usar Factory para crearlo y configurar los datos, y el repositorio para guardarlo:

/** @var \Magento\Catalog\Api\Data\ProductInterface $product */
$product = $this->productFactory->create();
$product->setSku('SAMPLE-ITEM');
$product->setName('Sample Item');
$product->setTypeId(\Magento\Catalog\Model\Product\Type::TYPE_SIMPLE);
$product->setVisibility(4);
$product->setPrice(1);
$product->setAttributeSetId(4); // Default attribute set for products
$product->setStatus(\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
// If desired, you can set a tax class like so:
$product->setCustomAttribute('tax_class_id', $taxClassId);

$product = $this->productRepository->save($product); // This is important - the version provided and the version returned will be different objects

Es probable que desee agregar algo de stock, lo que puede hacer así:

$stockItem = $this->stockRegistry->getStockItemBySku($product->getSku());
$stockItem->setIsInStock($isInStock);
$stockItem->setQty($stockQty);
$this->stockRegistry->updateStockItemBySku($product->getSku(), $stockItem);

Si está ejecutando esto en una secuencia de comandos (incluidas las secuencias de comandos de configuración / actualización), entonces también necesitará emular el área, ya que este tipo de cosas requiere sesiones por alguna extraña razón.

Para hacer eso, ingrese a \Magento\Framework\App\Statetravés del constructor y luego utilice este código:

$this->state->emulateAreaCode(
    'adminhtml', 
    function () { 
        /* all code here */ 
    }
);

use \Magento\Framework\App\Bootstrap;
include('app/bootstrap.php');

// add bootstrap
$bootstraps = Bootstrap::create(BP, $_SERVER);
$object_Manager = $bootstraps->getObjectManager();

$app_state = $object_Manager->get('\Magento\Framework\App\State');
$app_state->setAreaCode('frontend');

// get date 
$today_date = date("m/d/Y");
$added_date = date('m/d/Y',strtotime("+17 day"));

$set_product = $object_Manager->create('\Magento\Catalog\Model\Product');

try{
    $set_product->setWebsiteIds(array(1));
    $set_product->setAttributeSetId(4);
    $set_product->setTypeId('simple');
    $set_product->setCreatedAt(strtotime('now')); 
    // time of product creation
    $set_product->setName('Test Sample Products'); 
    // add Name of Product
    $set_product->setSku('add-sku-1');
    // add sku hear
    $set_product->setWeight(1.0000);
    // add weight of product
    $set_product->setStatus(1);
    $category_id= array(4,5);
    // add your catagory id
    $set_product->setCategoryIds($category_id); 
    // Product Category
    $set_product->setTaxClassId(0); 
    // type of tax class 
    // (0 - none, 1 - default, 2 - taxable, 4 - shipping)
    $set_product->setVisibility(4); 
    // catalog and search visibility
    $set_product->setManufacturer(28); 
    // manufacturer id
    $set_product->setColor(24);
    //print_r($_product);die;
    $set_product->setNewsFromDate($today_date); 
    // product set as new from
    $set_product->setNewsToDate($added_date); 
    // add image path hear
    $set_product->setImage('/testimg/test.jpg');
    // add small image path hear
    $set_product->setSmallImage('/testimg/test.jpg');
    // add Thumbnail image path hear
    $set_product->setThumbnail('/testimg/test.jpg');
    // product set as new to
    $set_product->setCountryOfManufacture('AF'); 
    // country of manufacture (2-letter country code)
    $set_product->setPrice(100.99) ;
    // price in form 100.99
    $set_product->setCost(88.33); 
    // price in form 88.33
    $set_product->setSpecialPrice(99.85); 
    // special price in form 99.85
    $set_product->setSpecialFromDate('06/1/2016'); 
    // special price from (MM-DD-YYYY)
    $set_product->setSpecialToDate('06/30/2018'); 
    // special price to (MM-DD-YYYY)
    $set_product->setMsrpEnabled(1); 
    // enable MAP
    $set_product->setMsrpDisplayActualPriceType(1); 
    // display actual price 
    // (1 - on gesture, 2 - in cart, 3 - before order confirmation, 4 - use config)
    $set_product->setMsrp(99.99); 
    // Manufacturer's Suggested Retail Price
    $set_product->setMetaTitle('test meta title 2');
    $set_product->setMetaKeyword('test meta keyword 2');
    $set_product->setMetaDescription('test meta description 2');
    $set_product->setDescription('This is a long description');
    $set_product->setShortDescription('This is a short description');
    $set_product->setStockData(
        array(
        'use_config_manage_stock' => 0, 
        // checkbox for 'Use config settings' 
        'manage_stock' => 1, // manage stock
        'min_sale_qty' => 1, // Shopping Cart Minimum Qty Allowed 
        'max_sale_qty' => 2, // Shopping Cart Maximum Qty Allowed
        'is_in_stock' => 1, // Stock Availability of product
        'qty' => 100 // qty of product
        )
    );

    $set_product->save();
    // get id of product
    $get_product_id = $set_product->getId();
    echo "Upload simple product id :: ".$get_product_id."\n";
}
