Php Magento 2从代码向购物车添加捆绑产品

我正在尝试插入一些带有子项的捆绑产品，以便结账/购物车。 我正在使用这段代码，但它只适用于简单的产品

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$product = $objectManager->get('Magento\Catalog\Model\Product')->load(703);

$listBlock = $objectManager->get('\Magento\Catalog\Block\Product\ListProduct');

$addToCartUrl =  $listBlock->getAddToCartUrl($product);

echo $addToCartUrl;

$product = $this->productRepository->getById("29");
$magento = array(21=>"1",22 => "2", 23 => "3");
$par = array('product' => $product->getId(),
             'bundle_options' => array(  1 => $magento),
             'qty' => $qty);
$this->cart->addProduct($_product,$par);
$this->cart->save();

我也用这个建议

$objectManager=\Magento\Framework\App\objectManager:：getInstance（）

$product=$this->productRepository->getById（“703”）

$magento=array（82=>“103”，82=>“112”）

$par=array（'product'=>$product->getId（），'bundle\u options'=>array（1 =>$magento），“数量”=>$qty）

$this->cart->addProduct（$\产品，$par）

$this->cart->save（）

但还是不行。有人能帮我吗？

谢谢

//查找下面添加捆绑产品的代码

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$product = $objectManager->get('Magento\Catalog\Model\Product')->load(703);

$listBlock = $objectManager->get('\Magento\Catalog\Block\Product\ListProduct');

$addToCartUrl =  $listBlock->getAddToCartUrl($product);

echo $addToCartUrl;

$product = $this->productRepository->getById("29");
$magento = array(21=>"1",22 => "2", 23 => "3");
$par = array('product' => $product->getId(),
             'bundle_options' => array(  1 => $magento),
             'qty' => $qty);
$this->cart->addProduct($_product,$par);
$this->cart->save();
