     foreach ($items as $item) 
      $resulta = $item->getName(); 
    } 
    $address = $addressInformation->getShippingAddress(); 
    $postcode = $address->getData('postcode'); 
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
    $result = $this->jsonResultFactory->create(); 
    throw new StateException(__($resulta));    
}

も

カートの製品を取得する必要があります

$ items = $ this - > _ cart-> getAllVisibleItems（）;空の値としてこの商品はカートに入れられます

あなたは製品名が必要なだけです。カスタムモジュールPHP機能で

：

protected $_quote; 

public function __construct(
    \Magento\Quote\Model\QuoteFactory $quoteFactory 
    /*Other DIs if you have*/ 
) 
{ 
    $this->_quote= $quoteFactory; 
    /*Other DIs if you have*/ 
} 

public function beforeSaveAddressInformation(
    \Magento\Checkout\Api\ShippingInformationManagementInterface $subject, 
    $cartId, 
    \Magento\Checkout\Api\Data\ShippingInformationInterface $addressInformation 
){ 
    //Inside 
    $cart = $this->_quote->create()->get($cartId); 
    $items = $cart->getAllVisibleItems(); 
    $result = []; 
    if (count($items) > 0){ 
     foreach ($items as $item) 
      $result[] = $item->getName(); 
      //If you need other fields, please let me know. 
      //$result[] = $item->getData(); 
    } 
    return $result; 
}
